Novel heteroatom-incorporated antofine and cryptopleurine analogues were designed, synthesized, and tested against a panel of five cancer cell lines. Two new S-13-oxo analogues (11 and 16) exhibited potent cell growth inhibition in vitro (GI50: 9 nM and 20 nM). Interestingly, both compounds displayed improved selectivity among different cancer cell lines, in contrast to the natural products antofine
设计、合成了新的掺入杂原子的安托芬和隐胸嘌呤类似物,并针对一组五个癌细胞系进行了测试。两种新的S -13-oxo 类似物(11和16)在体外表现出有效的细胞生长抑制(GI 50:9 nM 和 20 nM)。有趣的是,与天然产物 antofine 和 cryptopleurine 相比,这两种化合物在不同癌细胞系中表现出更高的选择性。作用机制 (MOA) 研究表明,R- antofine 在早期 S 期促进 DNA 复制失调,而在11和15中未观察到类似的影响在相应的复制起始复合物上。化合物11还显示出对正常细胞的细胞毒性大大降低,对小鼠 HT-29 人结肠直肠腺癌异种移植物的抗肿瘤活性中等,无明显毒性。
