Z-K8 (2), the racemic form of isochaihulactone (1), previously showed significant antitumor effects in A549 and LNCaP tumor-bearing mice. In the present study, 17 derivatives of 2 were designed, synthesized and evaluated for their anti-proliferative activity against four human tumor cell lines. All new derivatives exhibited high potency against A549 and P-glycoprotein (P-gp)-overexpressing KB-VIN. One of our new derivatives exhibited greater activity against three tested tumor cells (A549, KB, and KB-VIN) than 2, and induced cell cycle arrest in the G2/M phase. Moreover, SAR conclusions were first established for this series of compounds. Our study clearly identified a structural feature that should be retained for good activity and also a moiety that can tolerate various modifications and, thus, is ideal for further changes.

(±)-异chaihulactone衍生物的设计,合成及构效关系

Z-K8(2)是异硫氰酸氢内酯(1)的外消旋形式,以前在A549和LNCaP荷瘤小鼠中显示出显着的抗肿瘤作用。在本研究中,设计,合成了2种化合物的17种衍生物,并评估了其对四种人类肿瘤细胞系的抗增殖活性。所有新的衍生物均表现出对过表达A549和过表达P-糖蛋白(P-gp)的KB-VIN的高效力。我们的一种新衍生物对3种测试的肿瘤细胞(A549,KB和KB-VIN)表现出比2更大的活性,并诱导了G 2中的细胞周期停滞/ M阶段。此外,首先针对这一系列化合物建立了合成孔径雷达结论。我们的研究清楚地确定了为保持良好活性而应保留的结构特征,以及可以耐受各种修饰的部分,因此非常适合进行进一步的修饰。
