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.

s (DHDMBFs) are antiinflammatory and analgesic agents. Several other functional groups have been introduced at the 5 position: amides, amidines, ureas, guanidines, amines, heterocycles, heteroaromatics, and heteroaryl ethenyl substituents in the 5 position all provide active compounds. These compounds are dual cyclooxygenase (COX) and 5-lipoxygenase (5-LOX) inhibitors. They inhibit both COX-1 and COX-2

Abstract1,2‐O‐Isopropylidene‐3‐O‐methyl‐α‐D‐xylo‐pentodialdo‐1,4‐furanose and its 3‐O‐benzyl analog have been reacted with pyridinyl‐3‐methylenetriphenylphosphorane and benzimidazolyl‐2‐methylenetriphenylphosphorane. The unsaturated sugars so obtained are vinylogs of homo‐C‐glycosides whose conformation is easily determined. They constitute useful model compounds for pharmacologic studies.
