  The preparation of a series of 2-(1H-imidazol-1-ylmethyl)-substituted carboxylic acids of benzo[b]furan, benzo-[b]thiophene, indole, and naphthalene is described. All compounds showed a similar level of activity as TxA2 synthetase inhibitors in vitro, having IC50 values between 1 and 7 X 10(-8) M. In the cases examined, compounds had, at most, only negligible activity against PGI2 synthetase, cyclooxygenase
