ELECTROCHEMICAL STUDY OF INTERACTION OF THE HEAVY METAL IONS IN HYDROXYLATION REACTION OF SALICYLIC ACID ON GLASSY CARBON ELECTRODE
The formation of free hydroxyl radical (˙OH) in oxygen transfers at GCE and the reaction between the electrochemically produced ˙OH and salicylic acid (SA) is studied by cyclic voltammetry method. Experiments showed that ˙OH is formed in the potential range of 1.0-1.4V corresponding to the anodic discharge of H2O at the GCE. The interaction of Cu2+, Hg2+, Cd2+, Mn2+ ions on the hydroxylation re...

SELF-ASSEMBLED LIPID NANOTUBES, NANOSHEETS AND NANOPIPES
Three N,N’-diacyl-2,6-diaminopyridines were synthesized with a saturated undecanoic acid or an unsaturated undecenoic acid in order to study the effect of the alkyl-chain on the nano architectures. The imaging studies showed that the compound possessing two unsaturated alkyl chains exhibited a tubular structure. On the other hand compound possessing two saturated alkyl chain showed poorly formed...

SYNTHESIS AND STUDY OF ANALGESIC, ANTI-INFLAMMATORY ACTIVITIES OF BIS (INDOLYL) METHANES (BIMs)
Gastro-intestinal (GI) toxicity is the common adverse effect which has been associated with most of NSAIDs available in the market. So the search for new therapeutic agents with high margin of safety and freedom from normally associated GI toxic effects has been a priority of pharmacologists and pharmaceutical industries. There are virtually limitless series of structurally novel heterocyclic comp...

ANTIDEPRESSANT ACTIVITY OF DURENTA REPENS LINN.
The pet ether and chloroform extracts of Durenta repens leaves was screened for antidepressant action in tail suspension model. Both the extracts showed antidepressant action at the dose of 200mg/kg. Chloroform extract produced significant (p<0.001) mobilisation of the animals when compared with that of the standard drug Imipramine (10mg/kg) and acts as a potent centrally acting antidepressant ...
