ABSTRACT:
Novel 1-substituted-3-acylpyrrole derivatives of the formula ##STR1## wherein all symbols are as defined in the specification; and platelet aggregation inhibiting agents comprising them as active ingredients. These novel 1-substituted-3-acylpyrrole derivatives are prepared by condensing the corresponding 1-substituted pyrrole derivatives with the corresponding acylating agents in the presence of acid catalysts, and if desired, subjecting the products to oxidation, hydrolysis, amidation or acetal-forming reaction. These 1-substituted-3-acylpyrrole derivatives exhibit unique properties in that they have superior platelet aggregation inhibiting actions with low antiinflammatory activity.
