Phenanthroindolizidines, such as antofine and tylophorine, are a family of natural alkaloids isolated from different species of Asclepiadaceas. They are characterized by interesting biological activities, such as pronounced cytotoxicity against different human cancerous cell lines, including multidrug-resistant examples. Nonetheless, these derivatives are associated with severe neurotoxicity and loss
菲并吲哚里西啶,例如安托芬和泰洛佛林,是从不同种类的萝藦科植物中分离出来的一类天然生物碱。它们的特点是具有有趣的生物活性,例如针对不同人类癌细胞系(包括多重耐药细胞系)的显着细胞毒性。尽管如此,由于生物碱的高亲脂性,这些衍生物与严重的神经毒性和体内活性丧失有关。在这里,我们描述了安托芬和泰洛福林的高极性前药作为缺氧靶向前药的开发。所开发的菲并吲哚里西啶季铵盐表现出高化学和代谢稳定性,预计不会透过血脑屏障。在常氧条件下测试时,设计的前药显示出降低的细胞毒性。然而,在缺氧条件下测试时,它们的细胞毒性活性显着增加。
