3-Thio or amino substituted benzo[b]thiophene-2-carboxamides and 3-oxygen, thio, or amino substituted benzofuran-2-carboxamides are described as agents which inhibit leukocyte adherence to vascular endothelium and, as such, are effective therapeutic agents for treating inflammatory diseases. Certain of these compounds are novel and methods of manufacture are also described. The same benzo[b]thiophene and benzofuran-2-carboxamides also inhibit the activation of human immunodeficiency virus (HIV), latent in infected mammals.

The preparation of a series of 3,5-substituted indole- and benzofuran-2-carboxamides is described. A 3-alkoxy-5-hydroxybenzofuran was prepared by elaboration of a benzyloxy salicylate ester. A related 3-alkylthiobenzofuran was obtained by the addition of thionyl chloride and isopropylmagnesium chloride to a benzofuran ester. A series of 3-(methylthio)indoles was prepared from an indole sulfonium salt
