As part of an investigation to generate optimized drug leads from marine natural pharmacophores for the treatment of neoplastic and infectious diseases, a series of novel isoaaptamine analogs were prepared by coupling acyl halides to the C9 position of isoaaptamine (2) isolated from the Aaptos sponge. This library of new semisynthetic products was evaluated for biological activity against HIV-1, Mtb, AIDS-OI, tropical parasitic diseases, and cancer. Compound 4 showed potent activity against HIV-1 (EC(50) 0.47microg/mL), compound 19 proved to possess remarkable activity against Mycobacterium intracellulare with an IC(50) and MIC value of 0.15 and 0.31microg/mL, while compounds 4 and 17 possessed anti-leishmanial activity with IC(50) values of 0.1 and 0.4microg/mL, respectively. Compounds 16 and 17 showed antimalarial activity with EC(50) values of 230 and 240ng/mL, respectively, and compound 14 exhibited an EC(50) of 0.05microM against the Leukemia cell line K-562.
作为从海洋天然药效基团生成用于治疗肿瘤和传染病的优化药物先导物研究的一部分,通过将酰卤与从Aaptos海绵中分离出的异海兔胺(2)的C9位偶联,制备了一系列新型异海兔胺类似物。对这个新的半合成产物文库进行了针对HIV-1、结核分枝杆菌、艾滋病相关机会性感染、热带寄生虫病和癌症的生物活性评估。化合物4对HIV-1显示出强效活性(EC(50) 0.47μg/mL),化合物19被证明对胞内分枝杆菌具有显著活性,IC(50)和MIC值分别为0.15和0.31μg/mL,而化合物4和17具有抗利什曼原虫活性,IC(50)值分别为0.1和0.4μg/mL。化合物16和17显示出抗疟活性,EC(50)值分别为230和240ng/mL,化合物14对白血病细胞系K-562的EC(50)为0.05μM。
