Analogs of CPZEN-45, which is expected to be a promising new antituberculosis drug that overcomes the shortcomings of caprazamycins, were synthesized and their biological activities were evaluated. The biological activity of analogs 1-3, which converted the anilide portion, and analogs 4 and 5, focusing on the seven-membered ring, were lower than that of CPZEN-45. These results suggest that the inhibitory
CPZEN-45的类似物被合成,有望成为一种有前途的新型抗结核药物,克服了卡扎霉素的缺点,并对其生物活性进行了评价。转化苯胺部分的类似物 1-3 以及集中在七元环上的类似物 4 和 5 的生物活性低于 CPZEN-45。这些结果表明CPZEN-45对WecA的直系同源物Tago的抑制活性具有严格的结构限制,未来有望利用结构生物学阐明CPZEN-45的作用方式。
