A series of 2-substituted 4-(3-thienyl)imidazoles (6, 11, and 14) was synthesized and evaluated for antiinflammatory activity. Among them, 6g, 14a, and 14g exhibited strong activity, comparable to that of ibuprofen. The acute toxicity and the ulcerogenicity were low as compared with those of standard acidic antiinflammatory agents. The structure-activity relationships are discussed.
