Hence, the use of natural products for the abovementioned pharmacological aspects can be a suitable alternative. Lglutamine is an amino acid precursor for nicotinamide adenine dinucleotide. It is needed for the generation of reduced NAD in sickle cell erythrocytes.In the patient with SCA, glutathione and glutamine levels are low in spite of increasing availability of glutamine.These events possibly lead to an increase of oxidative stress and episodes of pain crisis.Though NAD production is adequate, but glutathione and glutamine levels in the erythrocyte are signicantly exhausted.Several plant extracts as well as pure molecules have been explored under the wide range of pharmacological treatment perspectives to manage SCA patients.Here, we are focused on the inhibition of hemoglobin polymerization activity by the characterized components in plant extracts or pure natural candidates.These two components as individual as well as in combination at same concentration level exhibit signicant protection against sickling of blood with respect to time. Larginine is an amino acid that helps for the production of nitric oxide.In SCA, nitric oxide level depletes that link to the complication of pain crisis.Further investigation of this compound reveals that it can protect the erythrocyte membrane from damage by transient oxidative species. Vanillin is a phenolic aldehyde mainly used as a avoring agentfood additive.This dual mechanism of vanillin may be responsible for antisickling activity. As vanillin is rapidly degraded in the upper gastrointestinal tract of oral administration, a prodrug of vanillin, namely, MX, was explored in transgenic sickle mice that can develop pulmonary sequestrations under hypoxic condition.Treatment of MX signicantly reduced the percentage of sickle cell in blood as well as prolonged the survival time after oral as well as intraperitoneal administration in severe hypoxic condition. It is reported that INN and INN, pyridyl derivatives of vanillin, increased antisickling activity by fold as compared to vanillin.Research on antisickling activity by naturally occurring vemembered heterocyclic aldehydes evolve that hydroxymethylfurfural inhibit sickling of homozygous sickle red blood cells up to at the concentration of mM.Results illustrated that this molecule increased the oxygen afnity of hemoglobin and displayed strong antisickling activity. Nix decreased the percentage of sickle cell to at. A clinical trial to access the safety and efcacy of NIPRISAN was carried out.This phytomedicine is found to be safe in terms of liver and kidney function test.Moreover, it signicantly lowered the frequency of pain crisis. It showed antisickling activities where burkinabins C is the most active component. It is reported that these have the ability to induce differentiation and globin gene expression in human erythroid cells. Further research by the same research group illustrated that ursolic acid is present in the same plant part.These showed dosedependent and timedependent inhibition of in vitro sodium metabisulfateinduced polymerization of hemoglobin using SCA patient blood samples.SCA is a botanical drug that exhibits both in vitro and in vivo antisickling activities.Clinical investigation depicts that it can able to reduce chronic pain, but limited data is available on its mechanism. Anthocyanin is a avonoid class of compounds present in several plants.Dosedependent activity on inhibition of sickling was attributed to anthocyanin also showed in vitro antisickling activity in sodium metabisulfateinduced blood sample.

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 buy Amiloride hydrochloride 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 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. Rohitukine was isolated as the constituent accounting for antiinammatory and immunomodulatory activity.Hyphenated techniquesbased dereplication and early identication of known compounds in crudefraction combined with bioassayguided fractionation drastically enhanced the drug discovery outcomes.LCMS is now considered as a major hyphenated technique widely used in academia and industry.This technique gained immense popularity in the last years, and hence the creation of databases or repository of MSMS fragmentbased mass spectrometry data has gained popularity in the eld of natural products dereplication.The standard MSMS fragmentation of a particular metabolite remains same under the same experimental conditions which can be considered as a signature or ngerprint of that particular metabolite.These signature proles help in the identication of known metabolites within the crude.These plants possess a wide range of bioactive principles which alone or synergistically act on different targets.

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, magnesium and sildenal were investigated to reduce the frequencyduration of painful crisis, but results are not encouraging.

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.
