Leflunomide Analogues as Potential Antiinflammatory Agents

概要

論文の詳細を見る
A series of leflunomide (1a) analogues were examined for antiinflammatory activity using the carrageenan-induced paw edema assay. Some of the compounds were significantly more potent than leflunomide, particularly those with electron-donating or negative inductive groups situated in the phenyl rings. In contrast, all the non-substituted compounds or with further chain-extension in the 4-position of the rings led to a decrease in activity. The LD, 0 values of the most active compounds (1d, g-j) in male ICR mice were significantly greater than those of either 1a or its active metabolite 2 and therefore merit further study.
