ABSTRACT
As part of ongoing studies in developing new antimicrobials, a novel series of 4-acetamido-N-(substituted 1, 3-benzothiazol-2-yl) benzenesulphonamide and N-(substituted 1, 3-benzothiazol-2-yl)-4-(substituted aryl diazenyl) benzenesulphonamide were synthesized in order to determine their antibacterial and antifungal activity. The synthesized compounds were tested in vitro against two Gram-positive bacteria like Staphylococcus aureus, Bacillus subtilis; two Gram-negative bacteria like Escherichia coli, Pseudomonas aeruginosaand one fungal strain Candida albicans in comparison with standard drugs. Microbiological results showed that the synthesized compounds possessed a broad spectrum of antibacterial and antifungal activity against the tested microorganisms. The compounds with a 6-chloro (SK5b), 7-chloro-6-fluoro(SK5d) and 6-nitro (SK5e) on 2-amino benzothiazole ring possessing azo linkage showed better antimicrobial activity; almost similar or less to that of standard drugs thus they could be promising candidates for novel drugs. The novel heterocyclic derivatives were characterized by Physical characterization (Melting point, TLC) and different Spectroscopy techniques (IR, ¹H NMR and Mass spectroscopy).

Abstract
Chemical synthesis data and their biological screening have provided a vast amount of experimental data. As a result of that, availability of large amount of biological data information through molecular biology has made drug discovery and development a more complex method. To combat these problems, Quantitative structure-activity relationships (QSAR) emerged as a very useful tool in drug design. QSAR has been applied extensively and successfully over several decades to find predictive models for activity of bioactive agents. QSAR have brought revolution in drug discovery process by thedevelopment of mathematicalrelationships linking chemical structures and pharmacological activity in quantitative manner of series of compounds. Description of the molecular structure, electronic orbital reactivity and the role of structural and steric components has been the subject of mathematical and statistical analysis. Computational drug design method in QSAR is a rapidly growing field which is now a very important component in the discipline of medicinal chemistry. Virtual filtering and screening of combinatorial libraries have recently gained attention as methods complimenting the high-throughput screening and combinatorial chemistry. These chemoinformatic techniques rely heavily on quantitative structure-activity relationships (QSAR) analysis, a field with established methodology and successful history.By characterize a specific aspect of a molecule that is numbers containing structural information derived from the structural representation used for molecules under study called “Molecular descriptors” to find appropriate representations of the molecular structure of drug compoundsto obtain the structure-activity relationships in which these theoretical and computational methods are based, the ability to predict physicochemical, pharmacokinetic and toxicological properties of these leads are becoming increasingly important in reducing the number of expensive methods and late development failures. Thus thereby, QSAR certainly decreases the number of compounds to be synthesized by easing the selection of the most promising candidates. This review seeks to provide a review on role of molecular descriptors in the drug design in QSAR.

Abstract:
Bullous Pemphigoid (BP) is an autoimmune subepidermal blistering disease appearing predominantly in the elderly. Bullous Pemphigoidcharacterized by an autoimmune response to 2 hemidesmosomal proteins within the dermal–epidermal junction, These proteins, called BP antigen 1 (BPAG1 or AgBP230), and BPAG2 (or AgBP180 or collagen XVII) have respective molecular masses of 230 and 180. While BP180 is a transmembrane glycoprotein with an extracellular domain BP230 localizes intracellularly and associates with the hemidesmosomal plaque. The disease is characterized clinically by tight bullae, with clear content, often large, developing primarily on the edge of erythematous plaques. Intense itching is common. The disease is primarily treated with systemic corticosteroids. Now,The increased knowledge of the development of noveltherapeutic strategies for Bullous Pemphigoids.

ABSTRACT:
The demand for mouth dissolving tablets has been growing during the last decade especially for elderly and children who have swallowing difficulties. Chlorpheniramine maleate is a non-steroidal anti-inflammatory drug (NSAID) histamine H1 antagonist with antihistamine drug it is commonly used  in allergic reactions, hay fever, rhinitis, urticaria, and asthma. The main criteria for mouth dissolving tablets are to disintegrate or dissolve rapidly in oral cavity with saliva in 15sec to 60sec with need of water. The disintegrants used should fulfill the criteria by disintegrating the tablets in specified time limit.in the present investigation variety of super disintegrants Crospovidone, sodium starch glycolate,kyron t-314 , were selected and tablets were prepared by direct compression method in different concentration like 3%,6% and 8%. The prepared tablets were evaluated for weight variation, hardness, friability, in vitro disintegration time, wetting time, in vitro dissolution study, etc.formulation f-9 shows the lowest disintegration time (29sec) and wetting time (37sec). In vitro dissolutionstudies revealed that formulation F-9 containning 9% t-314  showed 98% drug release at the end of 10 min.

Abstract:
Selective estrogen receptor modulators, called SERMs for short, blocks the naturally circulating estrogen in breast tissues and other estrogen-sensitive tissues in the body. Each estrogen receptor has a slightly different structure, depending on the kind of cell it is in. If a SERM binds to a estrogen receptor, there is no site available for estrogen to bind and it can't attach to the cell. SERMs are called "selective" because they bind to particular estrogen receptors. This selective binding action is sometimes called estrogen inhibition, or estrogen suppression.

ABSTRACT:-
In this review article, we discussed about Bioavailability and bioequilance study, bioavailability means rate and extent to which active ingredients absorbed from a drug product and become available at site of action. This article provides the information about important aspect involved in bioequivalence and regulatory requirement for bioequivalence study. The rate or rapidity at which drug is absorbed is important consideration in treatment of acute conditions such as asthma attack in pain. Extent of absorption is of special significance in treatment of chronic conditions like hypertension, epilepsy. In this review we discussed all the factors affecting bioavailability from its dosage form, objective/purpose of bioavailability study, design and evaluation of bioequilance study, methods of assessing of bioavailability and bioequilance etc.

Abstract
This study investigated the anti-inflammatory activity of the methanolic extract of Cissampelos pareira (Abuta) in male albino rats after intramuscular administration. This was done using the carragenin-induced paw edema method. Methanolic extract of Cissampelos pareira showed significant anti-inflammatory activity similar to ibuprofen and indomethacin.

ABSTRACT
This paper discussed the problems associated with nasal drug delivery and how it is possible, sometimes by means of quite simple concepts, to improve transport across the nasal membrane. It also described the advantages, barriers, physicochemical factors, and formulation related parameters that affecting the nasal drug delivery and the applications of nasal route for delivery of peptides, proteins, non-peptide drugs, and vaccines.  In this way it is feasible to deliver efficiently challenging drugs such as small polar molecules, peptides and proteins and even the large proteins and polysaccharides used in vaccines or DNA plasmids exploited for DNA vaccines. The transport of drugs from the nasal cavity directly to the brain is also described. Nasal vaccines offer several benefits, such as low enzymatic degradation compared to oral vaccines, and greater acceptability to patients. Nasal vaccines, however, have to overcome several limitations, including mucociliary clearance. Therefore, nasal vaccines require potent adjuvants and delivery systems to enhance their immunogenicity and to protect their antigens.
