epipodophyllotoxin derivatives (6-13), which were designed to overcome drug resistance and enhance topoisomerase II inhibition, were synthesized and evaluated. Two of these compounds (7 and 8) showed better preclinical activity profiles, including cell growth inhibition, cell killing, and in vitro topoisomerase II inhibition, as compared to the prototype molecule etoposide (1). They also retained the superior drug-resistance
合成并评估了八种新颖的表鬼臼毒素衍生物(6-13),这些衍生物旨在克服耐药性并增强对拓扑异构酶II的抑制作用。与原型分子依托泊苷(1)相比,这些化合物中的两种(7和8)显示出更好的临床前活性,包括细胞生长抑制,细胞杀伤和体外拓扑异构酶II抑制。他们还保留了目前正在临床评估中的表鬼臼毒素衍生物GL-331(4)的优异抗药性。
