Anti-inflammatory and analgesic profile of amidines of 3-amino-1,2,4-benzotriazine and 3-amino-1,2,4-benzotriazine-1-oxide.

Several formamidine and acetamidine derivatives prepared from 3-amino-1,2,4-benzotriazine and 3-amino-1,2,4-benzotriazine-1-oxide displayed an aspirin-like anti-inflammatory and analgesic profile. The test systems include adjuvant-induced arthritis in rats, carrageenan-induced edema in rats, UV-induced erythema in guinea pigs, the analgesic gait test, the antipyretic test, and GI ulcer studies.
