Abstract

Drug design and drug discovery have critical importance in human health care. There are various sites for the drug targeting like cell membrane, intracellular constituents, outside the cell and possibly antimicrobial action. Receptor as agonist and antagonist, enzymes and pumps, ion channels, physicochemical action with Lipid, protein or water constituents of nerve cell membrane are targeted on cell membrane. Various type of nuclear receptor like Oestrogen, retinoid, vitamin-D, Glucocorticoid, Thyroid hormone, peroxisome proliferators, liver receptor etc. are targeted on the intracellular constituents. The traditional approach of drug discovery involves target identification, validation, lead search and optimization followed by clinical development phases. The recent targets for drug action are DNA, Nuclear Receptors e.g. Retinoid Receptors, Ion Channels e.g. Calcium channel, Enzymes e.g. Cholinesterase, Receptors e.g. Adenosine Receptor in the present work different targets of drug action are discussed in brief which is an essential part during discovery phase of a drug.

Keywords

Abstract

Mycorrhiza is a mutualistic association between fungi and higher plants . Different types of mycorrhizae occur, distinguished by their morphology and to a certain extent, in their physiology. These include the ectomycorrhizae and endomycorrhizae. The ectomycorrhizae characterized by an external sheath of fungal cells surrounding the ischolar_main, often penetrates between the cells of epidermis and the first few cells of cortex and the fungal hyphae typically infect the ischolar_mains of forest trees of the temperate region. While mycorrhizae endomycorrhizae like vesicular arbuscular mycorrhizal (VA) fungi forms no sheath, the fungus infects the ischolar_main system of most cultivated crops and usually it invades several layers of the outer ischolar_main cortex. VA-fungal hyphae penetrate individual cells and form arbuscules within the cell and vesicles outside their host cells which led to their name. VA-fungi are associated with improved growth of many plant species due to increased nutrients uptake, production of growth promoting substances, tolerance to drought, salinity and transplant shock and synergistic interaction with other beneficial soil microorganisms such as N-fixers and P-solubilizer. Symbiotic association of plant ischolar_mains with VA-fungi often result in enhanced growth because of increased acquisition of phosphorus (P) and other low mobile mineral nutrients. Effective nutrient acquisition by VA-fungi is generally attributed to the extensive hyphal growth beyond the nutrient depletion zone surrounding the ischolar_main. Although a lack in growth response to VA-fungi inoculation in unsterilized soil was also recorded, this result has been attributed to the fact that native VA-fungi may provide the potential benefit of this mutualistic association.

Abstract

Biomarkers provide a dynamic and powerful approach to understanding the spectrum of disease with applications in observational and analytic epidemiology, randomized clinical trials, screening and diagnosis and prognosis. Defined as alterations in the constituents of tissues or body fluids, these markers offer the means for homogeneous classification of a disease and risk factors, and the can extend our base information about the underlying pathogenesis of disease. A prerequisite for the clinical use of biomarker is elucidation of the specific indication, standardization of analytical methods, characterization of analytical features, incremental yield of different markers for given clinical indications. Biomarkers can also reflect the entire spectrum of disease from the earliest manifestations to the terminal stages. The major use of biomarkers in clinical investigation.

Abstract

Cancer nanotherapeutics are rapidly progressing and are being implemented to solve several limitations of conventional drug delivery systems such as nonspecific biodistribution and targeting, lack of water solubility, poor oral bioavailability, and low therapeutic indices. To improve the biodistribution of cancer drugs, nanoparticles have been designed for optimal size and surface characteristics to increase their circulation time in the bloodstream. Nanoparticle has emerged as a promising strategy for the efficient delivery of drugs used in the treatment of cancer by avoiding the reticuloendothelial system, utilizing the enhanced permeability and retention effect and tumorspecific targeting. Delivery methods using nanoparticle are highlighted including both degradable and non-degradable polymers. The preparation techniques include emulsion polymerization, micelle polymerization, desolation of macromolecule, and emulsion-solvent evaporation methods. The particle size of the polymeric nanoparticle is in the nanometer range (10- 1000 nm) and is dependent on the method of preparation employed.

Abstract

The use of and search for drugs and dietary supplements derived from plants have accelerated in recent years. Ethno pharmacologists, botanists, microbiologists, and natural-products chemists are combing the Earth for phytochemicals and “leads” which could be developed for treatment of infectious diseases. While 25 to 50% of current pharmaceuticals are derived from plants. Traditional healers have long used plants to prevent or cure infectious conditions; Western medicine is trying to duplicate their successes. Plants are rich in a wide variety of secondary metabolites, such as tannins, terpenoids, alkaloids, and flavonoids, which have been found in vitro to have antimicrobial properties. This review attempts to summarize the current status of botanical screening efforts, as well as in vivo studies of their effectiveness and toxicity. The structure and antimicrobial properties of phytochemicals viz; Simple phenols and phenolic acids (spp.2) Quinones (spp.3) Flavones, flavonoids, and flavonol (spp.3), Tannins (spp.7) coumarins, (spp.1), Terpenoids and Essential Oils (spp.19), Alkaloids (spp.9) Lectins and polypeptides (spp.5) ,mixture (spp.4), other compounds (spp.1) and new antimicrobial plant origins (spp.7) are also addressed. Since many of these compounds are currently available as unregulated botanical preparations and their use by the public is increasing rapidly, clinicians need to consider the consequences of patients self-medicating with these preparations.

Abstract

Antioxidant the word itself is magic. Suggesting some type of allencompassing protection against cellular wear and damage, the scientific medical community has now embraced a once reviled theory. Using the antioxidant concept as a spearhead in proposed mechanisms staving off socalled “free radical” reactions, the rush is on to mine claim for the latest and most effect combination of free radical scavenging compound. They are therefore critical for maintaining optimal cellular and systemic health and well being. Defense strategies against such aggressive radical species include enzymes, antioxidants that occur naturally in the body (glutathione, uric acid, ubiquinol-10, and other) and radical scavenging nutrients, such as vitamins A, C, E, and carotenoids. This paper will present a brief discussion of some well-and little- known phyto pharmaceuticals (i.e. herbs) that may add to the optimization of antioxidant status and therefore offer added preventive values for overall health.

Abstract

Schiff Bases of 2-amino-5-aryl-1, 3, 4-thiadiazole derivatives have been synthesized with different aromatic aldehyde. 1, 3, 4-thiadiazole derivatives were prepared by the reaction of thiosemicarbazide, sodium acetate and aromatic aldehyde. The structures of the titled Schiff bases were elucidated by IR and ¹H NMR spectral measurements. All the compounds were evaluated for their analgesic activity against Swiss albino mice, anti-inflammatory activity against Wister albino rats.
