A series of organotin esters has been synthesized using a diverse array of drugs containing carboxylic function with triphenyl/tributyltin. The synthesized derivatives were bioevaluated for antibacterial, anti fungal and enzyme inhibition (alpha-amylase, alpha-glucosidase and butyrylcholinesterase) activities. Interestingly, compound 3c was found to be most potent in all bioassay and showed higher activity than the standards in case of antibacterial and antifungal activity.The molecular docking was utilized to ascertain the mechanism and mode of action towards the molecular targets indicating that ligands and complexes were stabilized at the active site by electrostatic and hydrophobic forces, consistent with the corresponding experimental results. Docking simulation providing additional information about the possibilities of the inhibitory potential of the compounds against the 1j7t and 1EAI. It has been predicted by in silico calculation and investigation of the binding pattern that compound 3c can serve as the potential surrogate for hit to lead generation and design of novel antibacterial and anti-leishmanial agents.

Synthesis of some newer derivatives of 2-amino benzoic acid as potent anti-inflammatory and analgesic agents
Diazotization of N-benzylidene anthranilic acids 1a-1n at pH 9 yielded N-[alpha-(phenylazo) benzylidene] anthranilic acids 2a-2n and at pH 3 yielded N-benzylidene-5-(phenylazo) anthranilic acids 3a-3n. When compounds 3a-3n were treated with thioglycolic/thiolactic acid in the presence of anhydrous ZnCl(2), 2-(4-oxo-2-phenylthiazolidin-3-yl)-5-(phenylazo) benzoic acids 4a-4n were afforded. The newly synthesized
