New chiral inhibitors of induced platelet aggregation: the enantiomeric specificity of (R)- and (S)-methyl and ethyl esters of 1-(4-[(1-hydroxycarbonyl)-ethoxy]-benzyl)-1H-1,2,3-triazole as a tool for determining their biological target.

The synthesis of title enantiomers was accomplished and their biological behaviour as inhibitors of rabbit platelet aggregation process induced by ADP and arachidonic acid was dtermined. Structure-activity comparison with that of SM-12502 [(2R,5S)-(+) 3,5-dimethyl-2-(3-pyridyl)-thiazolidin-4-one hydrochloride] and Dazoxiben {4-[2-(1H-imidazol-1-yl)-ethoxy]-benzoic acid} allowed us to formulate the possible capability for the synthesized compounds to interact with biological targets of the model molecules
