Synthesis of the 37 ageladine A analogs was accomplished by employing the total synthetic route of natural ageladine A previously explored by us. From the matrix metalloproteinase-12 (MMP-12) inhibitory activity assay carried out using the novel analogs, it appeared evident that the halogen atom at the 2-position of pyrrole ring was essential for the inhibitory activity and that the introduction of
通过使用我们之前探索过的天然阿格拉定A的总合成路线,可以完成37种阿格拉定A类似物的合成。从使用新型类似物进行的基质金属蛋白酶12(MMP-12)抑制活性分析中,可以明显看出吡咯环2位上的卤素原子对于抑制活性是必不可少的,并且引入了溴原子吡咯环的4-位上的杂合对于产生有效的活性非常有效。另外,吡咯环与咪唑环的交换在增加活性方面极其有效,并且发现由此获得的类似物29显示出比天然阿格拉德汀A强约4倍的有效活性。
