Natural alkaloid, tryptanthrin (indolo[2,1-b]quinazoline-6,12-dione) and its analogues are found to exhibit potent anti-tubercular activity against MDR-TB. A novel class of indolo[2,1-b]quinazolinones have been synthesized to evaluate their anti-mycobacterial activity. Enoyl-acyl carrier protein reductase (InhA) of Mycobacterium tuberculosis is one of the key enzymes and has been validated as an effective
发现天然生物碱类胰蛋白酶(吲哚并[2,1 - b ]喹唑啉-6,12-二酮)及其类似物具有抗MDR-TB的有效抗结核活性。已经合成了一类新型的吲哚[2,1- b ]喹唑啉酮来评估其抗分枝杆菌活性。结核分枝杆菌的烯丙基酰基载体蛋白还原酶(InhA)是关键酶之一,已被证实是有效的抗微生物靶标。在计算机分子对接研究中表明,合成的化合物对结核分枝杆菌显示出高亲和力药物目标InhA。费坦素是一种天然产物,属于色胺素家族,除了在第6位外,还显示出结构相似性。色胺素衍生物是通过修饰色胺素的酮官能团制备的。发现这些类紫杉醇同源物显示出有希望的抗结核活性。
