A novel series of antiinflammatory agents, N-isoxazolyl-3-carboxamides of 4-hydroxy-2H-1,2-benzothiazine 1,1-dioxide, was synthesized and evaluated as antiinflammatory agents in the carrageenin-induced rat paw edema (CIRPE) assay and adjuvant-induced polyarthritis (AIP) assay. Several analogues were found to be equipotent or more potent than aspirin and phenylbutazone. Structure-activity relationships
合成了一系列新的抗炎药,即4-羟基-2H-1,2-苯并噻嗪1,1-二氧化物的N-异恶唑基-3-羧酰胺,并作为角叉菜胶诱导的大鼠爪水肿(CIRPE)的抗炎药进行了评估分析和佐剂诱发的多关节炎(AIP)分析。发现几种类似物比阿司匹林和苯基丁氮酮等效或有效。讨论了构效关系。发现其中一种化合物为4-羟基-2-甲基-N-(5-甲基-3-异恶唑基)-2H-1,2-苯并噻嗪3-羧酰胺1,1-二氧化物(3a;异昔康)在CIRPE和治疗性AIP分析中,其效力是苯基丁a的3倍。Isoxicam(3a)目前正在作为抗关节炎药物进行III期临床试验。
