An agonist-antagonist switching strategy was performed to discover novel PPARα antagonists. Phenyldiazenyl derivatives of fibrates were developed, bearing sulfonimide or amide functional groups. A second series of compounds was synthesized, replacing the phenyldiazenyl moiety with amide or urea portions. Final compounds were screened by transactivation assay, showing good PPARα antagonism and selectivity
进行了激动剂-拮抗剂转换策略以发现新型的PPARα拮抗剂。已开发出带有磺酰亚胺或酰胺官能团的贝特类的苯二氮杂烯基衍生物。合成了第二系列的化合物,用酰胺或脲部分取代了苯基二氮烯基部分。通过反式激活试验筛选最终化合物,在亚微摩尔浓度下显示出良好的PPARα拮抗作用和选择性。在表达PPARα的癌细胞模型中进行测试时,选定的衍生物会诱导对细胞活力的显着影响。值得注意的是,3c,3d和10e在两种副神经节瘤细胞系中均表现出显着的抗增殖作用,其CC50低于商业PPARα拮抗剂GW6471,并且对正常成纤维细胞的毒性可忽略不计。
