Natural compounds for disease management -

The development of conventional insecticides focused on potent fast-acting agents. As previously mentioned, most of these successful agents affect the insect nervous system or other essential processes. NPs that act in a similar fashion are relatively rare, helping explain the contrasting high number of positive lab results and low number of leads in the pipeline Figure 3.

For active isolated compounds, the physico-chemical properties, toxicity and selectivity can be improved by semi-synthesis. For example, phenylpropanoids can be modified in a similar manner to eugenol derivatives to increase potency Barbosa et al. In some cases, larvicidal activity can be improved to the ppb level, as demonstrated in carnols from cashew nut shell liquid 11 ppm—2.

Structure-activity relationships SAR are important when constructing a nature-inspired active compound to be used in a final product. In such cases, where compounds are moderately active, they constitute hits as opposed to lead drug candidates Guantai and Chibale, This is also important to improve properties such as lipophilicity logP.

Other causes of low potency can relate to test scale Silva et al. Our group performs an initial small-scale test in 3 ml well plates in order to screen NP compounds frequently isolated in low quantities.

The World Health Organization WHO recommends testing with cups — ml which, due to the increased scale, decreases the activity of many compounds or alters solubility Silva et al. Another important consideration is the Ae. aegypti strain used in initial laboratory studies, frequently the Rockefeller strain.

Less promising activity can be observed in field-collected laboratory tests, small-scale field and field tests which involve exposure of native mosquito strains Melo-Santos et al.

Loss of potency after isolation may also be attributed to synergic effects. Plants produce secondary metabolites which target pathogens through several combined mechanisms Caesar and Cech, , commonly the case for the insecticidal action of essential oils such as rosemary oil Miresmailli et al.

In this case, the use of extract standards should be considered Demarque et al. Strategies that exploit synergic effects gather compounds in the same formulation, one such example is pyrethrin formulations with slow pyrethrin detoxification, piperonyl butoxide PBO , N-octyl bicycloheptene dicarboximide MGK , rotenone and ryania Dimetry, Nanoparticles also offer an excellent alternative Benelli, NP prototype development is hindered by the source itself, as native plants whose commercial interest has not yet led to their domestication, limits scale-up.

Genetic variability, together with all climatic and environmental factors involved in secondary metabolite production, may also affect the presence of compounds of interest Gobbo-Neto and Lopes, ; Gobbo-Neto et al.

In addition, antifeedant molecule production may be triggered by the presence of predators, with intermittent production impacting collection. All plant parts can be collected, with leaves more readily accessible.

Unnecessary plant part collection can be reduced by employing prior metabolomic analysis to detect the molecule of interest when the target is known. This specific type of analysis is termed targeted metabolomics. Another strategy, which is both environmentally and economically advantageous, is using abundant sources of raw material, such as industrial waste and commercialized ornamental or food plants Singha and Chandra, Furthermore, the latter poses less risk to humans.

Commercial compound screening constitutes another approach Chen et al. Residuality studies are mandatory in insecticide development.

Biodegradation of plant insecticides limits their prolonged presence in the environment which is one of their main advantages Schulte et al.

There is a fine balance between insecticide efficacy over a defined period and biodegradation. Environmental persistence is undesirable, but necessary to guarantee residuality, facilitate the logistics of application, reduce costs Isman, and above all successfully control the vector.

Strategies employed to improve formulation stability and effectiveness include nanoformulation and microencapsulation Werdin González et al. The impregnation of zedoary oil in sand granules also remarkably prolonged activity from 5 days to 3 weeks Champakaew et al.

In addition, the presence of antioxidants can prolong insecticide residuality as observed in pyrethrin formulations Dimetry, Although it may seem a less problematic consideration, finding the right combination to maintain the active ingredient soluble and dispersible in water can prove difficult, as most actives are highly apolar compounds, exemplified by the aforementioned compounds.

Arboviral disease control is almost completely reliant on an insecticide-based strategy. Considering that commercially available insecticides persist in the environment, harm non-target organisms, promote resistance in mosquitoes, and pose long-term risks for humans and the environment, new strategies are clearly needed to control the Ae.

aegypti vector. Genetically-modified mosquitoes can constitute part of a future alternative control strategy, although effectiveness is still being evaluated Wilke et al. Therefore, we highlight the importance of natural products as an important source of chemical prototypes for new product development.

Despite this apparently low number, the impact of NP chemistry in new insecticide discovery is notorious in terms of the development of novel chemical leads and mechanisms of action.

Herein we highlighted i the potential of NP as a source of compounds for new product development, together with ii the bottlenecks associated with NP-based insecticide development and iii the technological advances providing a more streamlined discovery strategy Figure 4.

FIGURE 4. Bottlenecks that NP chemistry needs to address to develop agents against arbovirus vectors. In summary, anthropogenic activities continue to foster arboviral vector proliferation and hamper disease control efforts.

Multidisciplinary teams are essential to tackle the aforementioned significant challenges, exploit natural products to obtain prototypes and, most importantly, shorten the development time of novel insecticides.

Shah, F. The corresponding risk of developing PD was 2. Changes in a significant number of other genes were thought to be PD-causative and were discovered by linkage analysis or a candidate gene approach, in addition to the genes responsible for the six monogenic types of PD.

A higher risk of developing PD has been linked to variants in a number of PARK-designated SNCA, UCHL1, LRRK2, PARK 16, GAK and a few additional genes MAPT, GBA, NAT2, INOS2A, GAK, HLA-DRA, and APOE Postuma et al. Parkin, DJ-1, ubiquitin C-terminal hydrolase isozyme L1 UCH-L1 , nuclear receptor-related factor 1, and α-synuclein are genes linked to either Parkinson- or Parkinson-related diseases.

Because it rapidly aggregates and forms the majority of Lewy bodies LBs , α-synuclein is particularly noteworthy. The α-synuclein that has accumulated interacts to the proteasome and effectively suppresses proteasomal action.

Proteasomal dysfunction is believed to play a role in the pathogenesis of PD because ubiquitin builds up in LBs and interacts with the proteasomal system through interactions with parkin and UCH-L1.

PD is a complex neurodegenerative disorder ND. As a result, nigrostriatal dopaminergic neuron function declines and cholinergic neuron the function rises, resulting in movement problems Phani et al. The majority of contemporary opinions believe that fibrillation and aberrant α-synuclein aggregation are the primary components in the PD clinical occurrences.

Furthermore, the existence of Lewy bodies LBs made up of α-synuclein is a significant pathological marker of PD. As a result, α-synuclein may be linked to PD Stefanis, ; Zhang et al. This article discusses newly identified natural compounds having substantial anti-PD capabilities, as well as the current state of research into their medicinal chemistry.

However, age or the aging process is the single most important predictor of the beginning of PD. The most widespread explanation is that as normal cellular physiological and biochemical processes fail more frequently, dopaminergic neurons become more sensitive to toxic assault.

Dopaminergic cells aging linked with L-type calcium channels Surmeier et al. In reality, most models of cell death in PD disregard the role of age or aging, and young animals are used to represent the disease process in the great majority of experimental research Hindle and Ageing, When looking at the prevalence of PD, the same might be said about men outnumbering women Shulman, Despite evidence that estrogen plays a role in determining the age at which women develop PD and its effect on dopaminergic neuron function, no explanation for the disparity has emerged.

Industrialization, rural areas, well water, plant-derived toxins, bacterial and viral infection, and exposure to organic solvents, carbon monoxide and carbon disulfide are some of the broad environmental factors on the prevalence of PD Tellier et al.

Despite inconsistent results from various research and the difficulty of identifying specific pesticide compounds that may be connected to an increased risk of PD, pesticide exposure has recently attracted interest Richardson et al.

Paraquat and rotenone are two specific agrochemicals that have been shown to cause dopaminergic cell death in the nigral area of mice Berry et al. Some of these will be discussed later while discussing pathogenic mechanisms. Exercise, anti-inflammatories, antihypertensives mostly calcium antagonists and antilipidemic all seem to lower the risk, but the role of some, like anti-inflammatories, exercise, antihypertensives mostly calcium antagonists and antilipidemic, is still unknown Ascherio et al.

However, MPTP-induced parkinsonism differs from typical PD in that it does not develop in humans, there is no LB development and there is no pathology in other parts of the brain that are damaged in human illness. PD is a neurological, progressive condition that causes a number of motor and crippling abnormalities, including as bradykinesia, resting tremor, muscle stiffness and imbalance.

Dopamine levels in the striatum, tailed nuclei and putamen are reduced as a result of the slow, progressive degeneration of dopaminergic neurons in the SN compacta, which is a pathological hallmark of PD.

The most significant pathogenic finding in the brains of PD patients is the progressive loss of dopaminergic neurons in the basal complexes. Dopamine neurotransmitter levels in this region are decreased as a result of the destruction of these neurons. However, studies have shown that oxidative stress and mitochondrial dysfunction probably play a key role in the pathogenesis of PD; the loss of nigrostriatal dopaminergic neurons and the presence of intracellular cytoplasmic proteins, i.

The precise molecular mechanism of the degradation of dopaminergic neurons and the incidence of PD is unknown. The cells are transmitted to the putamen from the nigrostriatal neurons in the SN pars compacta SNpc.

Depigmentation of SNpc results from the absence of these neurons, which normally contain modest levels of melanin Lees, PD, the most prevalent form of Multiple Sclerosis MS , results from the progressive degeneration of dopaminergic neurons along the nigrostriatal pathway Hacker et al.

Magnetic resonance diffusion tensor imaging revealed signs of neurodegeneration in the nigrostriatal circuits Wang et al. PD is caused by a variety of causes that cause neurodegeneration. Recently some researcher found missing of the substantial nigra of the PD patients, investigators also revealed abnormalities of the mitochondria in skeletal muscle, platelets and lymphoblast that basically indicate direct link between mitochondrial dysfunction and PD Schapira et al.

PD patients with mitochondrial dysfunction confirmed by pathologically especially in sporadic PD, against a backdrop of increased oxidative stress and elevated brain iron levels, this helps us to understand how mitochondrial abnormalities interconnected in PD pathogenesis Dexter et al.

The discovery of specific mutations in genes that cause dopaminergic cell death and familial PD have confirmed the role of mitochondria in the development and pathophysiology of PD.

Many instances of PD with PINK1 or LRRK2 mutations, on the other hand, are clinically indistinguishable from spontaneous PD. Several knockouts or expression models of these mutations have been discovered to exhibit mitochondrial function abnormalities Moon, Parkin is a ubiquitously transcribed protein that has been linked to the endoplasmic reticulum, synaptic vesicles, Golgi apparatus, and mitochondria in intracellular investigations Shimura et al.

The alternative method to investigating PD etiology has been to look at the pathological components of the disease process. The formation of LBs and the existence of a reactive microgliosis, which may contribute to disease progression, are two characteristics of PD. The LB has long been regarded as the distinguishing hallmark of PD, although its significance in the disease process has been debated.

It has been alternately described as a pathogenesis marker and a graveyard for dead and dying neurons. In PD α-synuclein mutations is common and in sporadic PD LBs strongly immunoreactive for wild-type α-synuclein with many other protein in their normal or damaged condition Spillantini et al.

The discovery of parkin and UCH-L1 mutations, as well as their involvement in the ubiquitin-proteasomal system, ushered in a new age of research into changes in protein processing in dopaminergic cells via both proteasomes and lysosomes Eldeeb et al.

The argument has been fanned by postmortem tests and toxicology research. In the substantia nigra, there is a decrease in proteasomal enzyme activity that is unique to PD and does not occur in other parts of the brain McNaught et al.

McGeer et al. Microglia with DR positivity McGeer et al. Furthermore, elevated pro-inflammatory mediators such as TNF, ILβ, IL6, iNOS, and COX two have been found in the striatum and substantia nigra, according to this study Tansey et al.

As previously mentioned, PD is linked to aberrant α-synuclein aggregation, which activates microglia even more Su et al. Neuroinflammation is characterized by the activation of microglia and reactive astrocytes in the brain, as well as the production of inflammatory mediators such as cytokines TNF-α, IL-1, and IL-6 , chemokines, complement cascade proteins, reactive oxygen species, and reactive nitrogen species RNS.

Several factors have been shown to reduce the permeability of the blood-brain barrier BBB da Fonseca et al. The degeneration of the nigral dopaminergic neurons in PD is caused mainly by inflammasome-induced neuroinflammation.

Baicalein, a flavonoid derived from the Scutellaria baicalensis Georgi plant used in traditional Chinese medicine, has been shown to have anti-inflammatory and neuroprotective effects in animal models of NDs, including PD.

Biloba DeFeudis and Drieu, In a PD rat model treated with 1-methylphenyl-1,2,3,6-tetrahydropyridine MPTP , long-term use of EGb prevented the loss of dopaminergic nerve terminals caused by MPTP Ramassamy et al.

EGb was shown to protect against dopaminergic neurotoxicity caused by MPTP whether it was given before or after the treatment Sharma et al. This suggests that levodopa is neurotoxic and that EGb may reduce this toxicity Fei et al. A previous study found that the ginsenosides Rb1 and Rg1 both decreased MPTP-induced cell death in SN-K-SH cells a neuroblastoma cell line Rudakewich et al.

Rg1 protects cells against apoptosis caused by MPTP by increasing Bcl-2 and Bcl-xl expression, decreasing Bax and iNOS expression and blocking caspase-3 activation Chen et al.

Ginsenosides protect by lowering intracellular reactive oxygen species ROS , boosting antioxidant activity, maintaining complex I activity, and raising intracellular Adenosine triphosphate ATP levels, according to research.

Men are more impacted than women Gualtieri, DLB diagnostic criteria differ substantially in their sensitivity and specificity and improved criteria are needed Lopez et al.

Cases with more substantial DLB disease have typical symptoms, whereas cases with larger neurofibrillary tangles are likely to show AD Ballard et al. Continuing to work memory issues, visual spatial difficulties, psychotic episodes, melancholy, unconcern, and low mood are among early signs of DLB Simard et al.

Degeneration of the corticobasal ganglion is gradual, with unilaterally akinesia and rigidity responding badly to apraxia especially ideomotor apraxia and levodopa. Myoclonus of the cerebral reflex, limb rigidity, alien limb signs, and cortical sensory loss is all symptoms Riley et al.

Despite the fact that there are various requirements for diagnoses were submitted, none were validated and their warnings were explored elsewhere Litvan et al.

The estimated prevalence per , individuals is 4. Insomnia at night and daytime sleepiness are prevalent among people with PD Figure 3. The most prevalent complaint of PD patients in nighttime sleep is many nightly awakes or fragmented sleep Factor et al. PD fragmentation of sleep A lot of etiology including nightly recurrence of PD symptoms, medicine, coexisting apnea of sleep, and regular limb sleep movements Comella et al.

Patients with PD may experience nocturnal waking and difficulty sleeping Factor et al. Levodopa medicament can reduce the fragmentation of sleep owing to recurring symptoms and enhance early-morning function Askenasy and Yahr, ; Juncos et al.

FIGURE 3. PD with different types of sleep disorder like sleep fragmentation, REM Rapid Eye Movement , Breathing problem during sleep Apnea , increase daytime sleep and finally depression.

Obstructive sleep apnea was once thought to be a minor issue in PD since it was generally associated with a high BMI. Sleep apnea, on the other hand, is more frequent in PD than previously thought.

Despite having a normal BMI, 20 to 50 percent of PD patients tested by sleep study had significant apnea, according to descriptive investigations Ferini-Strambi et al. People with multiple system atrophy MSA have a high prevalence of respiratory problems during sleeping.

MSA patients may have difficulty breathing during sleep due to vocal cord abductor paralysis Isozaki et al. REM behavioral disorder is a sleep condition characterized by muscular movement in REM sleep with dream activity Schenck et al. REm atony-free sleep RWA displays aberrant muscle activation without obvious behavioral behavior during REM sleep Gagnon et al.

In patients with Basic RBD, a SPECT scan reveals a reduction in dopaminergic transport which is midway among normal controls and Parkinson patients without parkinsonism Eisensehr et al.

The typical complaint of PD-patient patients is excessive daily drowsiness EDS. This problem has been characterized as sleep daily for PD patients on ropinirole or pramipexole, as well as a result of motor vehicle accidents recorded in Hobson et al. Dementia and the fast advancement of parkinsonism were related to the onset of EDS Gjerstad et al.

Since its debut in the s, levodopa has been known to produce drowsiness. Although community studies indicated that almost any dopamine agonist, particularly levodopa, may cause EDS, it was shown that levodopa was the most closely connected to the disease Hauser et al.

Epidemiological studies are regarded as a common non-motor discovery in PD and prevalence calculations range from 2. The degree of depression moderate to serious and the definition of depression undoubtedly influence these figures.

Estimates dispute PD age and depresence, as well as the period of disease, severity of disease, and gender problems Olanow et al. Neurochemical and neuroimaging approaches have been appraised in the functions of dopamine, norepinephrine and serotonin, although no definite pathophysiological mechanism is recognized.

A function was proposed for an allelic variant in the serotonin transporter Mössner et al. In this way, Bax may stop apoptosis from happening while Bcl-2 helps it happen and both caspase-3 and caspase-9 can stop Bcl-2 from doing its job. By forming the TPHIPK2-AXIN1 complex, HIPK2 Homeodomain-interacting protein kinase-2 can control the creatine kinase and transcriptional activation of TP53 Tumor protein This slows down cell growth and speeds up cell death Li et al.

Pedicularioside A exerts a protective effect on mesencephalic neurons, increasing their longevity. Pathogenesis of PD is exacerbated by neuroinflammation and oxidative stress Li et al. Some transcription factors, for instance MAFG, can promote nNOS by raising NRF1 expression.

Nuclear factor erythroidrelated factor 2 Nrf2 protein levels and transcriptional activity, as well as overexpression of Nrf2-dependent genes, were shown to rise following therapy. A ligase modulatory component is seen in SH-SY5Y cells Jing et al. The dopamine transporter DAT is in charge of DA re-uptake by altering the PP2A kinase pathway, α-synuclein inhibits VMAT2 but enhances DAT function Dorsey et al.

Immunohistochemistry results showed that treatment with ME dried mulberry fruit extract greatly reduced the overexpression of SNCA Synuclein Alpha and ubiquitin, which are two of the most important parts of LBs Gu et al. The herb derived Anti-Parkinson components may produce very good activity.

Some of these components are displayed in Table 1. Numerous laboratories are investigating the remarkable properties of the tropical legume M. pruriens for the treatment of PD. For the first time, a multicentric preclinical trial described the efficacy of the herbal preparation HP derived from the tropical legume for the treatment of the disease, which was administered to 60 PD patients for 12 weeks Sengupta et al.

niger has been utilized for a variety of ailments in the traditional medical systems of many cultures, including Indian, Chinese, Roman, and Byzantine.

No reference is made in the literature to its independent usage for the treatment of parkinsonism in either human patients or any animal model. However, a clinical research has confirmed its efficacy when combined with three additional Ayurvedic herbs. niger contains little L-DOPA Nagashayana et al.

A relative excess of the neurotransmitter acetylcholine exists in the striatum due to the depletion of DA in PD, which is thought to be one of the causes of the many motor impairments linked to PD. Anticholinergics are therefore used to treat PD, especially tremor Mirahmadi et al.

In a 6-OHDA-rat model of PD, an ethanolic extract of the Ayurvedic plant N. jatamansi roots can reduce neuronal damage Ahmad et al. The extract effectively decreased the neurotoxin-induced lipid peroxidation, increased GSH content, the activities of GT, GR, GP, SOD, and catalase, attenuated the loss of catecholamines, increased DA-ergic D 2 receptor binding, and increased TH-immunoreactivity in the animals before 6-OHDA lesioning.

jatamansi extract also dose-dependently reversed the dopaminomimetics-induced rotations and deficits in locomotor activity and muscular coordination brought on by nigrostriatal degeneration. Ayurveda makes extensive use of this plant as a brain booster.

Recent preclinical studies have demonstrated its effectiveness in treating PD. monnieri extract was found to have significant preventive action in the paraquat-induced PD model in Drosophila and mice, principally through antioxidant capabilities and restoration of the mitochondrial ETC complexes activities Ravikumar and Muralidhara, ; Hosamani et al.

But in the future, real-world studies should look into how well plant extracts and their active parts work in PD models Mercuri and Bernardi, ; Diaz and Waters, Aside from the fact that the gold standard, levodopa, does not operate on the cause, there is an additional restriction in that the symptoms become exceedingly severe after a lengthy period of therapy Odin et al.

Another significant issue with L-dopa is that it promotes neurodegeneration by causing oxidative stress Pahwa and Lyons, While levodopa has all of these side effects, other PD medications might cause sleep difficulties and cognitive issues such disorientation and psychosis, MAO-B inhibitors, COMT inhibitors, and other similar drugs anticholinergic medications Yuan et al.

Due to great success, DBS Deep brain stimulation in the subthalamic nucleus STN and globuspallidus internus GPi is currently the most popular therapy Rocchi et al. However, DBS has the same drawbacks in that it does not stop the disease from developing and does not prevent it from deteriorating various signs and symptoms Tsai et al.

Rehabilitative therapy is a type of treatment for PD that involves daily exercises such as stretching and muscle strengthening, exercises to strengthen and improve posture Tomlinson et al.

Further research is warranted to explore several folklore or traditional medicinal herbs and their myriad of bioactive phytochemicals to develop new safe and effective anti PD drug agents Sharma et al.

We discovered that several organic substances and herbal extracts display varied anti-Parkinsonian properties. When numerous PD neurotoxic models are coupled, they give a good framework for discovering anti-Parkinsonian drugs, and herbal medications can be employed to develop novel PD treatments.

But in the future, real-world studies should look into how well plant extracts and their active parts work in PD models. Additionally, there is still a need for more thorough explanations of the constituents and methods of action of herbal extracts. To assure strong reproducibility, to boost therapeutic benefit, and to lessen the possibility of harm, methodological improvements must be made to upcoming clinical studies using natural products for the treatment of PD.

The study design should include double blinded trials and the use of placebos. Before beginning clinical trials, protocols must be established to ensure the openness of the study findings. DC vaccination is a cell-based treatment. It uses antigen-loaded or sensitized DCs as the vehicle for vaccination to cause an immune response, and it is very important for getting early immune responses.

T-cells become activated when they are exposed to antigen Steinman, ; Boer et al. Also, peptide-sensitized DC PSDC vaccines cause an antigen-specific immune response that lasts longer than traditional vaccinations Steinman, In some way, these DCs have become sensitized. Nevertheless, current experimental and clinical evidence strongly imply that, in order to deliver significant therapeutic effect, the clinical candidate cell must be of human origin and possess the following characteristics: A neuron in the substantia nigra Lindvall et al.

After intrastriatal transplanting, a large percentage of substantia nigra dopaminergic neurons survived for a long time, there were no tumors seen in the rodents.

Furthermore, a large area of the brain was re-innervated thanks to the transplants in a bigger nonhuman primate brain, the striatum and behavioral impairments that resemble symptoms have improved in PD patients Lindvall et al.

Grealish and others found that grafts of human ES cell-derived dopaminergic neurons placed in a mouse were effective, axonal regeneration is possible in the rat model of PD as well as functional growth and long-term survival efficacy more than the human foetal mesencephalic dopaminergic neurons Grealish et al.

Even if no tumors have been found, safety is still an important consideration when considering human transplantation, Dopaminergic neurons generated from ES cells in patients with PD Kriks et al.

In , gene therapy was first proposed as a way to replacing bad DNA with good DNA Friedmann and Roblin, There are a variety of techniques, but the most common is the use of designed non-replicating viral vectors, primarily recombinant viruses of various serotypes lentivirus or adeno-associated virus AAV Lang et al.

Treatments with non-disease modifying medications aim to relieve the symptoms of PD by attempting to restore aberrant firing of dopaminergic or GABA-producing enzymes in the basal ganglia Axelsen and Woldbye, So, we can expect that the gene therapy will be one the most promising therapeutic technique.

Deep brain stimulation DBS or localized treatments may help patients with PD enhance their quality of life and functional independence Weaver et al.

Surgical lesions and deep brain stimulation DBS improve medication and reduce dyskinesia as compared to standard medical therapy Vitek et al. New surgical and stimulation approaches are reshaping the sector, and technology improvements may enhance possible outcomes.

Surgical decision-making is difficult, as it involves determining the best surgical candidates, among other things, such as methodology, complication management, hardware, and code changes, all of which necessitate a multidisciplinary team effort Mitchell and Ostrem, MR: Writing original draft; XW, MI, SA, FS, MM, MH-O-R: Collection of data and analysis; Most.
