A series of 2-(4-methylphenyl)benzothiazoles was synthesized and evaluated using an adjuvant-induced arthritic rat model. This calss of desired compounds affecting the immune response was found using hemagglutination assay.4-Acetoxy-2-(4-methylphenyl)benzothiazole (7m), KB-2683, was most potent in the adjuvant-induced arthritic rat model and selected for further evalution. In contrast to nonsteroidal antiinflammatory drugs, compound 7m showed no antiinflammatory or analgesic activities. It did, however, show an immunomodulatory activity in enhanced delayed type hypersensitivity.
合成了一系列 2-(4-甲基苯基)苯并噻唑,并使用佐剂诱导的关节炎大鼠模型进行了评估。在佐剂诱导的关节炎大鼠模型中,4-乙酰氧基-2-(4-甲基苯基)苯并噻唑(7m),即 KB-2683 的药效最强,因此被选为进一步评估的对象。与非类固醇抗炎药物相比,化合物 7m 没有显示出抗炎或镇痛活性。不过,它在增强型迟发型超敏反应中显示出了免疫调节活性。
