Development of new drugs, especially in the area of oncological and infectious disease represents today one of the most important research fields. The marine environment is a tremendous source of natural products. Many new compounds isolated from marine micro- and macroorganisms showed prominent biological effects, mostly antibiotic and cytotoxic activities. The current study aimed to investigate pure compounds which were isolated from marine-derived fungi. The study was preformed with fractions from two marine derived fungal strains, i.e. Verticillium teneru and Acremonium sp. The isolation of the desired secondary metabolites was carried out using different chromatographic separation techniques (TLC, VLC and mainly HPLC). Chemical and spectroscopic methods (1D NMR, 2D NMR, MS, IR and UV) were applied for structural elucidation of the separation compounds. Extracts of two algal-derived fungus strains with high cytotoxic properties, were investigated chemically. This investigation resulted in the isolation and structure elucidation of three pure compounds representing different structural sub-classes, one of them 1 proved to be new natural products and two were known compounds2 & 3.

Majority of crude drugs from plant origin are used in Indian system of medicine. Medicinal plants are using as herbal remedies to prevent and cure several ailments differs from community to community. Most studies on the exploitation of mango have been dealing with mango peels, juices and stem bark and mango leaves. Mangifera indica (Anacardiaceae), reported to contain active substances like mangiferin. In ayurveda, one of its uses is clearing digestion and acidity. Mangiferin is a pharmacologically active flavonoids, which having the anti bacterial, antioxidant, anticancer, antidiabetes, hepatoprotective, anti inflammatory activities.

Plants have been used in treating cardiovascular diseases (CVD) and are recognized for their ability to produce secondary metabolites. Secondary metabolites obtained from different plants have been the starting material for designing different drugs. Echinosystic acid, a pentacyclic triterpene was isolated and identified from the fruits of Gleditsia sinensis Lam. Echinosystic acid has significant cardioprotective effects. Different phytochemicals have been found to be cardioprotective and paved the path towards development of cardioprotective formulations. In the present study we have analyzed the inhibitory potential of Echinosystic acid, on the Angiotensin Converting Enzyme (ACE) - the enzyme responsible for various cardiovascular diseases.
The study revealed that Echinosystic acidhave high ACE inhibiting potential as compared to other known ACE inhibitors.

Different heterocyclic analogues were evaluated for their diverse biological activities. The triazole moiety seems to be very small but in the biological profile has attracted the attention of many researchers to explore this skeleton to its multiple potential against several activities. Triazole analogues have a wide range of biological applications including antimicrobial, antimalarial, antitubercular, anti-inflammatory, analgesic, antiepileptic, antiviral, antihypertensive, antianxiety, antidepressant, antihistaminic activities etc. This review provides a brief response of the medicinal chemistry of triazole analogues particulary as analgesic and anti-inflammatory activities.

Microspheres are well accepted technique to control the drug release from the dosage form to improve bioavailability, reduce absorption difference in patients, reduce the dosing frequency and adverse effects during prolong treatment. The main objective of the present study is to prepare and evaluate ibuprofen microspheres by solvent evaporation method, with water insoluble polymers such as Ethyl cellulose and sodium carboxymethyl cellulose as suspending agent, using as carrier for oral administration in view to achieve oral sustained release of the drug. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) used for relief of signs and symptoms of rheumatoid arthritis, osteoarthritis and is used in chronic and acute conditions of pain and inflammation. Its biological half-life is 2 ±0.5 hrs. Due to its low biological half-life (2 hrs), it requires frequent administration to maintain plasma concentration. This causes inconvenience to the patient and also leads fluctuations in plasma drug concentration that may cause inferior therapeutic effects or toxic effects. There-fore, development of controlled release dosage forms would clearly be beneficial in terms of decreased dosage requirements, thus increase patient compliance. The formulations were evaluated for particle size distribution analysis, flow properties like Angle of repose, bulk density, tapped density, Hausner’s Ratio, Carr’s index, Encapsulation efficiency, Scanning electron microscopy,optical electron microscopy and invitro release studies. The optimized formulation showed good invitro sustained release activity of the drug ibuprofen.

When pregnant mother consumes drugs it reaches the fetus through the placenta, in the same way that oxygen & nutrients are delivered to the baby in the mother’s uterus. Depending upon the drug taken, the amount, duration & stage of pregnancy, it can produce varying effects on growing baby. Drugs can damage the fetus &cause developmental abnormalities (producing birth defects) & result in still birth. The objectives of the study were to assess the knowledge regarding teratogenic effect of drugs among staff nurse working in maternity and pediatric wards. Structured Knowledge Questionnaire on teratogenic effects of drugs was used to evaluate the knowledge of Staff Nurses. The results revealed that out of 30 staff nurses selected for the study, majority 19 (63.3%) possessed average knowledge regarding teratogenic effect of drugs.

Infertility is the inability of an animal or plant to reproduce by natural means. Many people in the world are facing the problem of infertility altimatlely the problem of saving their generations. Today, modern science chalanged and solved the problem of infertility by developing the technique of Test Tube Baby by using principle of in-vitro fertilization.
Dr. Subhas Mukherjee, first Asian who invented most easy and successful method of producing Test Tube Baby. In Culcutta, West Bengal, on 3rd October 1978, the team announced the birth of World's Second Test Tube baby named as 'Durga' (Kanupriya Agarwal). The announcement came 67 days after the birth of World's First Test Tube Baby named as 'Louise Brown in England by Physiologist Robert G. Edwards who awarded the Nobel Prize for such work in 2010. During his lifetime, Government of West Bengal didn't recognized his work. By the day to day insult from government Dr. Subhas Mukherjee committed to suicide.

Delivery of drug through Transdermal route represents a most convenient and novel approach. Transfersomes were found to be more effective as they render controlled release of drug due to depot formation in skin and were more effective in transdermal delivery. Transfersomes are applied to the skin and permeate through the stratum corneum lipid lamellar regions as a result of the hydration and osmotic force in the skin. Transfersomes have been widely used as a novel carrier for transdermal drug delivery. The Transfersomes can be evaluated by in vitro for vesicle shape and size, entrapment efficiency, degree of deformability, number of vesicles per cubic mm. Transfersomes enhances the penetration of most of the low as well as high molecular weight drugs. When tested in artificial systems transfersomes can pass through even tiny pores (100 nm) which are 1500 times smaller. The use of transfersomes carrier results in delivery of high concentration of active agents through the skin, regulated by system composition and their physical characteristics. Thus, this novel technique has got a great potential for overcoming current problems faced by the conventional techniques.

Scopolamine a cholinergic antagonist may cause amnesia in human and animal models. Amnesia induced by Scopolamine has been widely used to understand the biochemical and behavioral changes in rodents. This model can be used to describe the therapeutic targets of memory impairment. In this model the Scopolamine decreases the central cholinergic neuronal activity, block muscarinic receptor and induces oxidative stress. Cholinesterase inhibitors (Donepezil, tacrine, galantamine, and rivastigmine are widely used in the treatment of amnesia. These inhibitors showed non-significant effects. Therefore, herbal medicine can be the sources for the treatment of memory loss due to their Antiacethylcholine esterase and antioxidant activities. In this paper introducing the medicinal plants and their components affecting amnesia on the scopolamine induced model are discussed.
