In an attempt to develop effective and safe anticancer agents, we designed, synthesized and examined 23 novel quinacrine (QC) derivatives by combining the 9-aminoacridine scaffold and the [1,3]thiazinan-4-ones group. Most of these hybrids showed strong anticancer activities, among which 3-(3-(6-chloro-2-methoxyacridin-9-ylamino)propyl)-2-(thiophen-2-yl)-1,3-thiazinan-4-one (25; VR151) effectively killed
为了开发有效和安全的抗癌药,我们通过结合9-氨基ac啶支架和[1,3] thiazinan-4-ones组设计,合成和检查了23种新的奎纳克林(QC)衍生物。这些杂种大多数表现出强的抗癌活性,其中3-(3-(6-氯-2-甲氧基methoxy啶-9-基氨基)丙基)-2-(噻吩-2-基)-1,3-噻嗪南-4-一种(25 ; VR151)有效杀死了许多不同类型的癌细胞,包括八种具有不同遗传背景的乳腺癌细胞系,两种前列腺癌和两种肺癌细胞系。相反,化合物25对非癌细胞的杀伤力较弱,表明对人体的毒性可能较小。我们的数据表明,由于DNA复制的下调,癌细胞在S期停滞了很长时间,最终导致细胞死亡。我们还表明,S期阻滞可能是由于细胞周期蛋白A的下调加上细胞周期蛋白E的持续上调所致,这与mTor-S6K和mTor-4EBP1途径的下调相吻合。
