A new set of highly substituted pyridine derivatives has been synthesized by a product selective four component reaction of aryl aldehyde, malononitrile and 2-aryl/cyclohexylsulfanyl-1-aryl-1-ethanones in presence of sodiumhydroxide in methyl/ethylalcohol. Among the compounds, 4,6-bis(4-chlorophenyl)-5-[(4-chlorophenyl)sulfanyl]-2-methoxynicotinonitrile (4n) inhibited Mycobacterium tuberculosis (MTB)

High-throughput screening resulted in the identication of a small molecule inhibitor of PAR1. Optimisation of the initial hit led to the discovery of compounds 34 and 49, which displayed antithrombotic activity in an arteriovenous shunt model in the rat after iv administration.

Diasteroselective synthesis of highly substituted N-hydroxypiperidine was achieved by an intramolecular reductive cyclization of monoxime (2) of the 1,5-diketone (1), generated from 2-(cyclohexylthio)-1-phenylethanone and arylaldehyde, using NaBH3CN. The major product N-hydroxypiperidine (3) has been found to be racemate of a single diastereomer.
Pyrazole derivatives from azines of substituted phenacyl aryl/cyclohexyl sulfides and their antimycobacterial activity
Azines derived from substituted phenacyl aryl/cyclohexyl sulfide on treatment with excess phosphorous oxychloride in N,N-dimethylformamide have been found to yield two isomeric pyrazoles in each case. A plausible mechanism has been suggested for the formation of the products. The antimycobacterialactivity of the isomeric compounds has been tested against Mycobacterium tuberculosis (MTB).
