3-(Phenethylamino)demethyl(oxy)aaptamine (1) was re-discovered from the marine sponge of Aaptos sp. as an anti-dormant mycobacterial substance through the bioassay-guided separation. Compound 1 showed potent anti-microbial activity against Mycobacterium bovis BCG with a minimum inhibitory concentration of 0.75 µg/mL under both aerobic conditions and hypoxic conditions inducing dormant state. Compound
从Aaptos sp。的海洋海绵中重新发现了3-(苯乙氨基)脱甲基(氧)aptapamine(1)。通过生物测定指导的分离,作为一种抗休眠的分枝杆菌物质。化合物1在有氧条件和缺氧条件下(都处于休眠状态)均显示出对牛分枝杆菌BCG的有效抑菌活性,最低抑菌浓度为0.75 µg / mL。化合物1还有效对抗致病性结核分枝杆菌菌株,包括临床耐多药菌株。此外,成功地合成了1及其类似物3-氨基脱甲基(氧基)Aaptamine(2)有足够的数量用于进一步的生物学研究。
