The effect of structural change on the biological activity of a series of imidazothiazoles and thiazolobenzimidazoles is described. It was found that compounds with polar substituents at the 2 or 3 position of the ring system are less acutely toxic while maintaining antiinflammatory activity. Other structural changes, such as the incorporation of a gem-dimethyl substituent in the 6 position, increase
描述了结构变化对一系列咪唑并噻唑和噻唑基苯并咪唑的生物活性的影响。发现在环系统的2或3位具有极性取代基的化合物在维持抗炎活性的同时毒性较小。其他结构变化,例如在6位掺入宝石二甲基取代基,会增加急性毒性并消除抗炎活性。具有最佳活性/毒性比的化合物在噻唑环上包含烷基磺酰基取代基。噻唑并苯并咪唑类似物比咪唑类似物更有效。
