This chapter is focused on the effect of natural products in pure form or characterized phytoconstituents on particularly inhibition of hemoglobin polymerization.This summarized information will be benecial for further exploration of new therapeutics in the treatment arena of SCA.Millions of people around the world, especially children, have been affected by SCA. This global burden is a growing concern nowadays as the yearly increase of newborns with SCA is expected from around three to four lakhs between and. SCA, congenital hemolytic anemia, is caused by a single amino acid substitution. This shows the way for polymerization of deoxygenated sickle hemoglobin which is the crucial step in the molecular pathogenesis of SCA.This polymerization alters the RBC rheology by changing its surface property, membrane damage, and dehydration of RBC.Potassium chloride cotransport and calciumactivated potassium efux are generally involved during the process of RBC dehydration. During this process, shape of RBC is changed from round disk to crescent moonlike structures.These dehydration events further show the way to reduce the RBC volume with rise in hemoglobin concentration at intracellular level in parallel. This conformational change in RBC directs toward hemolysis and vasoocclusion leading to ischemia followed by pain crisis.Generation and impairment of oxidative stress is involved during the abovementioned process. Gene therapy can provide a proper solution to tackle the abovementioned pathophysiological conditions, but currently, research including clinical trials have been ongoing. A vast range of drugs have been explored for symptomatic management of these disease conditions that are discussed below.As natural products have immense potential for the treatment of a broad range of disease conditions, supplementationadjuvant therapy with natural products can be a suitable alternative.Hydroxyurea is an anticancer agent that inhibits ribonucleotide reductase.Despite several advantageous effects of hydroxyurea, the major limitation is its myelosuppression effects. Azacytidine, decitabine, and pomalidomide are the representatives of this class of molecules. This molecule has been reported to extend halflife of RBC and sanguinate. Inhibition of platelet aggregation is benecial to prevent vasoocclusion.Therefore, antiplatelet agents have been investigated for the management of SCA.Investigation of it was carried out earlier for SCA. Prasugrel is an antiplatelet agent and irreversible antagonist of PY adenosine diphosphate receptors.It interferes with adenosine diphosphatemediated platelet activation as well as aggregation.The ability of prasugrel to reduce the rate of vasoocclusive crisis in the clinical trial is not promising for the treatment of SCA patients. Anticoagulant medications are also used to treat and prevent blood clots.Rivaroxaban are the two anticoagulant drugs under clinical trial for SCA.Pan selectin inhibitors are another class of molecule that mediates adhesion of RBC to vascular endothelium linked to vasoocclusion. Tinzaparin is lowmolecularweight heparin and is used as antithrombotic drug.There are several other molecules that have been investigated for the management of SCA because of their additional pharmacological activity instead of its current pharmacological use like simvastatin, a hypolipidemic agent that activates endothelial nitric oxide, and propranolol, a nonselective adrenergic blocker that hinders sickle RBC adhesion. It was found to be effective for prevention of vasoocclusive crisis in SCA patients. To improve the vascular tone and endothelial dysfunction, purchase Naloxone hydrochloride magnesium and sildenal were investigated to reduce the frequencyduration of painful crisis, but results are not encouraging.

There are several diseases caused by microbial infection while others are caused due to disregulation of primary metabolic and body defense systems, which are evolved to protect body from suffering.There are many examples, where plant products have made their irony contribution toward disease management. In, another antimalarial drug called chloroquine was synthesized and used for the treatment of malaria; however, due to their synthetic origin, the pathogen develops resistance, which was more problematic. Generally, it is evident that the diabetic people have more chances of cardiovascular attacks than the nondiabetic ones. Up to now only plasmamediated transfusion of drugs are available to treat diabetes due to their sensitivity toward digestive enzymes, which inactivates them upon consumption when taken through oral routes; therefore, it is desirable to think toward some oral form of alternatives.In this context, plants can be the best alternatives, and more than plants are available and reported to show antidiabetic properties without causing any complication. Stevia rebaudiana, which was reported to be more than hundred times sweeter than the sugar, possesses hypoglycemic action in diabetic patients. The possible mechanism of action of taxol was believed to occur due to arrest of cells in GM phase of the cell cycle, while camptothecin exhibits their action by inhibiting the activity of topoisomerase I enzymes involved in DNA replication. Several other compounds like topotecan, irinotecan, docetaxel, podophyllotoxin, teniposide, and elliptinum have been documented to showed anticancerous properties. The antiretroviral therapy is the most signicant approach used for their treatment, and it is recommended that all patients with detectable HIV infection should be treated with antiretroviral therapy to prevent their subsequent progression as well as to reduce transmission. Galanthus nivalis performed its action by preventing the binding of viral envelop protein to the host cells receptor, therefore inhibiting hostspecic recognition. The important disease caused by bacteria include diarrhea, tuberculosis, typhoid, and many more, while fungi caused mycotoxicosis, which is characterized by immune suppression, liver cirrhosis, abnormal fetus development, stunted growth, and sometimes cancers. Different chemical preservatives and shelf life enhancers have been used since long time to eradicate these contaminants and their toxins; however, their indiscriminate use may lead to the development of resistance stain of these contaminants and residual toxicity to the nontarget organisms and to the environments. In this context, many authors have claimed the importance of plantderived essential oils and their bioactive compounds as safer candidate for the preservation of these food items.In the last two decades, herbal formulations have been proven to act as effective strategies, and many plant bioactive compounds, namely, epigallocatechin gallate from tea, quercetin from onion and apple, acacetin from black locust, and genistein from bean plants have been proved to have antiviral and hepatoprotective properties. None of the medicines discovered till date have been reported to completely reverse multiple sclerosis; however, sometimes it is believed that the utilization of plantderived compounds can be the effective strategies, and this may restore the functioning of neurons inammation.In this regard, some important plants and their derivatives have been used and reported by many workers against multiple sclerosis.

This hyphenated technique shows the promising results for the analysis of small combinatorial libraries containing up to molecules. Common derivatization method is the conversion of the component to trimethylsilyl, acetyl, and methyl derivatives.But, on hydrolysis, and acetylation of active fraction followed by GCMS analysis, only two peaks were identied as phorbol tetraacetates by comparison with phorbol triacetate. Since a lot of organic compounds produce peaks at characteristic wavelengths, FTIR is a useful detection technique.But, due to the presence of solvents producing intense peaks in the same region, this technique is much less sensitive than other detection methods like UV and MS.HPLC separation followed by NMR analysis is a potential technique for the investigation of natural products. HPLCSPENMR has an important advantage over HPLCNMR in that the compounds are accumulated on SPE cartridges by repetitive adsorption.Further, the analytes are extracted by deuterated solvent, so that compounds are concentrated in detection cells, resulting in increased reasch Norfloxacin sensitivity of this hyphenated technique. The extract was submitted to online LCNMR to conrm the above ndings and to obtain more structural data.Compound was conrmed as decussatin, and compound, responsible for antifungal activity, was nally identied as the known methoxy, naphthoquinone. Optimization also requires modifying, replacing, or adding functional groups and stereo centers or extreme remodeling of the fundamental scaffold to optimize physicochemical and pharmacokinetic properties.Thus, natural products are guiding principles or natural productbased design and synthesis of compound libraries. The application of synthetic chemistry to modify the leads of the natural product has long been used to produce compounds with improved pharmacological properties.This semisynthetic approach has been widely used either to generate more similar compounds randomly or to improve lead natural product candidates. For example, aspirin is the best and rst example; it was synthesized from salicin.Similarly, the cholesterol lowering semisynthetic simvastatin is more potent than parent lovastatin. Taxol is one of the most effective anticancer drugs ever developed.Similarly, camptothecin was identied as potent anticancer agent; later the solubility issue was resolved by semisynthesizing potent anticancer compounds topotecan and irinotecan that are widely used for cancer treatment.There are a number of potential candidates of natural origin used for semisynthesisbased natural product libraries.One of the excellent examples of natural product inspired total synthesis is the discovery of avopiridol.

Similarly, other traditional systems of medicine produced a huge wealth of knowledge.By, approximately of approved medicinal products were either originated from naturally occurring compounds or were motivated by a natural product.The importance of natural products has been extensively reviewed and it was found that out of the new drugs introduced between and, of the smallmolecule approved drugs were either natural products or derived from natural products and another were created around a pharmacophore from a natural product. Plants use these secondary metabolites for defense and signaling.Thus, they are important for the survival and reproductive tness of plants.Secondary metabolites, therefore, represent adaptive characters that have been subjected to natural selection during evolution. Several specic interactions of secondary metabolites with proteins and other cellular components have been discovered.Structures of these metabolites appear to have been shaped during evolution in such a way that they can mimic the structures of endogenous substrates, hormones, neurotransmitters, or other ligands. Hence, these compounds are results of an evolutionary relation, and the internal signaling pathways respond to many of the primordial exocrine signaling systems found today in ancient marine animals as well as in the plants. Parallel discovery of high throughput screening and the knowledge of molecular targets of diseases, along with the introduction of combinatorial chemistrybased synthesis, dramatically shifted efforts toward the synthetic medicinal chemistry.Natural products are biosynthesized in small amounts and present in extracts as mixtures, isolation of which is an effortful and tedious procedure.Obtaining additional quantities for preclinical development requires a largescale reacquisition or fermentation that would have a signicant impact on the growth timeline.When screening natural product libraries, rediscovery of known compounds is a major problem.This is due to the lack of active dereplication methodologies.Natural products are often complex in terms of structure.It is often difcult to alter the complex natural products using organic chemistry.To meet the above challenges, various concepts have emerged in the natural productbased drug discovery.Natural productlike compounds can be obtained either by isolation or synthesis based on natural products.These two categories can be classied further according to different concepts involved in methodology, and has been discussed in subsequent subheads.Around, higher plant species have been estimated, and only of that has been investigated pharmacologically and phytochemically. Synthetic chemistry and natural sources are two major sources for these compounds of interest.Subsequent validation steps required for lead identication, preclinical development, and clinical development at the discovery level of molecules from plants involve several crucial steps such as plant selection, extraction, isolation, and characterization before its biological testing.In these systems, to prevent or control complex diseases, many herbal preparations are considered ideal than a single active ingredient.Studies have shown the ability of plant metabolites such as quercetin, catechins, resveratrol, piperine, and curcumin to potentiate the activity of various anticancer drugs. Various digital platforms, databases, and documents have been compiled to keep this information in a B.Various plants have been classied according to their traditional uses; this information can be used to choose plant material to isolate compounds of interest.Primary way of authentication is morphological as well as anatomical analysis, based on texture and organoleptic properties.

Therefore, a massscale clinical trials and specic documentation on its molecular mode of action is needed.Based on the aforementioned background, the present chapter describes the documentation of important medicinal plants and their derived bioactive principles, potential to combat important human diseases with underlying mode of action to facilitate A.It is estimated around of the drugs launched worldwide and more than population of the developing countries basically rely on plant products for their preliminary health care or as a supplement for health. According to WHO, it has been estimated that, species of plants exist on the earth, up to now, only around or, plants have been used as medicines by humans to treat these complications.In spite of their appreciated potential against different human diseases, their exploration as medicine directly to human has faced several challenges due to lack of scientic and clinical evidence regarding their biochemical mode of action on particular cells, tissues, or organs as well as standardization issues.Based the aforementioned background, the present chapter deals with exploration of some important medicinal plants for the development of drugs, which are useful for treatment of severe humans ailments.The knowledge of thousands of years of traditionally used herbal medicines can be used to overcome several medical problems of present generations.The development of medicine for the early humans was not an easy task; several of them have sacriced their lives during the course of testing of plants with some benecial medicinal importance.Some plants might be poisonous, harming their lives.Medicinal plants are the major source of traditional medicines as well as some modern medicines.It comprises of four elements: monarch, minister, assistant, and servant according to their roles in the formula.Unani medicine is also recognized by WHO as alternative medicine system for curing the sufferers.The body temperature of a human being shows its wellbeing and mental and physical status.Alteration in the body temperature makes the human body susceptible to many kinds of diseases.The traditional medicine system is well integrated in the scheme of national healthcare system of the country and well organized. The other two, SE and SY are called kidney and pancreas types, respectively. Plants have several secondary metabolites in the form of phytochemicals which protects plants from invasion of pests and infection from microorganisms.These phytochemicals have some active ingredients which can be used in the form of drug for the treatment and prevention of disease. Phenolic compounds of plants are most valuable among the secondary metabolites because of their active role in morphological development, reproductive process, and physiological responses.There are about structures of different plant phenolic compounds known to us.The central skeleton of phenolic compounds is formed by one phenolic ring, and hydrogen is replaced by more active residues like hydroxyl, acetyl, and methyl groups.This is the reason behind wide spectrum of biological properties of phenolic compounds.In plants, these phenolic compounds are assembled in phenolic rings and are called polyphenols. Phenolic compounds containing plants have high antioxidant properties.Plants absorb the radiation of sun and produce oxygen as a byproduct.Oxygen gets activated by UV light and heat generated by sunlight and produces reactive oxygen species, which interfere with cellular entities and alter them leading to cellular damage.
