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.

Synthesis and Conformational Features of 4-(Cyclohexylsulfanyl)-1-(2,4-dinitrophenyl)-3-aryl-1<i>H</i>-pyrazole
[image omitted] A set of new 4-(cyclohexylsulfanyl)-1,3-diaryl-1H-pyrazoles has been synthesized using Vilsmeier's reagent. It is found that 4-(cyclohexylsulfanyl)-1-(2,4-dinitrophenyl)-3-(4-methoxyphenyl)-1H-pyrazole exists with the arylthio group in the equatorial position of the cyclohexyl group in solution, whereas it has the arylthio group in the axial position of the cyclohexyl group in crystal state as evidenced by NMR and single-crystal x-ray analysis respectively.

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.
