The synthesis and screening of a series of 5-(3-pyridylmethyl)benzofuran-2-carboxylic acids as selective thromboxane A2 (TxA2) synthase inhibitors is outlined. The ability of these compounds to inhibit TxA2 biosynthesis was assayed using microsomal enzyme from human platelets. Substitution of the benzofuran ring caused small changes in potency; modification of the carboxylic acid group caused modest reductions in potency, and substitution of the pyridine ring resulted in large reductions of potency. 5-(3-Pyridylmethyl)benzofuran-2-carboxylic acid sodium salt (9b, sodium furegrelate) was chosen for further evaluation as a TxA2 synthase inhibitor.
