Porphyrins are ever-present large class of naturally occurring macrocyclic compounds with many significant biological representatives comprising heme and chlorophyll. Novel bi-metallic porphyrins derived from [5-(4-hydroxyphenyl)-10,15,20-tri(4-methyl phenyl) porphyrin] and salicylideneamino-2-(N,N-dimethylamino) ethane copper (II) perchlorate was obtained in good yields. The results from various ...
Protein conformation and dynamics are influenced by various factors, including binding of ligands, their physico-chemical properties, etc. Every conformational change is dictated by an array of events, as making and breaking of bonds or change in interaction of protein residues. The three dimensional structure of protein molecules are widely investigated, based on small world network approaches, w...
SYNTHESIS OF NEW TWO DERIVATIVES OF 6-MERCAPTOPURINE (6MP) 6-[5-PYRIDINE-4-YL- 1, 2, 3, 4-OXADIAZOLE-2-YL)DITHIOL]-9H-PURINE (38) AND 9H-PURINE-6-YL-BENYLDITHIOCARBAMATE (45) WITH CYTOTOXICITY RESULTS FROM THE NATIONAL CANCER INSTITUTE’S ANTICANCER DRUG SCREEN
6-[(5-pyridine-yl-1, 2, 3, 4-oxadiazole-2-yl)dithiol]-9H-purine (38) and 9H-purine-6yl-benzyldithiocarbamate (45) are synthesized as possible prodrugs for 6-mercaptopurine(6-MP). The generation of the compounds 38, 42, 45 and 48 were accomplished following multistep reaction procedures. The reaction and purity of the products were checked by TLC, the structure of the final compounds and their inte...
LOCALIZATION OF CONNEXIN 36 AND CALCITONIN GENE RELATED PEPTIDE AS A DETERMINANT OF NEUROPATHIC PAIN IN THE TRIGEMINAL GANGLION
The trigeminal ganglion consists of pseudounipolar neurons surrounded by satellite glial cells and processes innervating craniofacial region. The trigeminal ganglion consists of neurons which are of first order pseudounipolar carrying sensory pathway from the receptors from face, mouth, scalp and duramater. The gap junctions are trans-membrane proteins formed between the cell membranes of adjacent...
IDENTIFICATION AND ANALYSIS OF LEAD COMPOUNDS AGAINST HIV-1 INTEGRASE ENZYME USING ADMET PREDICTION AND DOCKING ANALYSIS
Acquired immune deficiency syndrome (AIDS), one of the most challenging diseases world-wide is caused by human immunodeficiency virus (HIV), member of human retrovirus family. Various therapies and treatments of HIV are provided, but these are rapidly drug resistance in recent decades. After the explosion of HIV integrase (enzyme essential for the replication of DNA virus in the host genome), phar...
Angiogenesis is process of new blood vessel formation that occurs under both normal and pathological conditions. In the normal state, two distinct processes can be seen. One utilizes endothelial progenitor cells (EPC) and the second utilizes existing vasculature to generate new vessels. The healthy body controls angiogenesis through a series of "on" (angiogenesis-stimulating growth factors) and "o...
AUS - Ayurveda, Unani and Siddha is the traditional system of medicines in India more than 3000 years old and still practiced extensively in India and neighbouring countries. Assurance of the safety margin, potency of medicinal plants that make the herbal products has now become a key issue in industrialized with developed countries. Pharmacological studies is a science relating to the screening, ...
SYNTHESIS AND PHARMACOLOGICAL EVALUATION OF SUBSTITUTED N-(3-FORMYL-4-OXO-4H-CHROMEN-2-YL)-N- PHENYLBENZENESULFONAMIDE AND ITS DERIVATIVES
Modification of a drug molecule of a series having optimal activity is widely used and continues to be an important factor necessary for new drug discovery. Infectious diseases which increase dramatically by resistant and multi resistant microbes are now a days the second major cause of death worldwide and the third leading cause of death in the developed countries. Although, the search for new le...
TERBINAFINE INCORPORATED SODIUM HYALURONATE MICROSPHERE MUCO-ADHESIVE SYSTEM FOR VAGINAL CANDIDIASIS
The aim of the present investigation was to prepare and evaluate novel bioadhesive vaginal microspheres containing Terbinafine (TBH) in order to provide long-term therapeutic activity at the site of infection and prove the same using in vitro anti fungal activity of the same using Candida albicans. Microspheres were prepared by the Solvent extraction technique using sodium hyaluronate and Arlacel ...
AMELIORATIVE EFFECT OF HYGROPHILA AURICULATA (K. SCHUM) HEINE ON LIPID PEROXIDATION IN A RAT MODEL OF N-NITROSODIETHYLAMINE INDUCED HEPATOCELLULAR CARCINOMA
This study was designed to investigate the ameliorative effect effect of Hygrophila auriculata (H. auriculata) on lipid peroxidation (LPO) in N-nitrosodiethylamine induced Hepatocellular Carcinoma (HCC) in rats. Experimental rats were divided into different groups: normal, N-Nitrosodiethylamine induced hepatocellular Carcinoma bearing rats, H. auriculata treated hepatocellular carcinoma bearing ra...
