Nitro seco-1,2,9,9a-tetrahydrocyclopropa[c]benz[e]indol-4-ones (nitroCBIs) are a new class of prodrugs for antitumor therapy that undergo hypoxia-selective metabolism to form potent DNA minor groove alkylating agents. Although hindered by poor aqueous solubility, several examples have shown activity against hypoxic tumor cells in vivo. Here we investigate structural properties that influence hypoxic
Nitro seco -1,2,9,9a-tetrahydrocyclopropa [ c ] benz [ e ] indol-4-ones(nitroCBIs)是一类用于抗肿瘤治疗的新型前药,其经过缺氧选择性代谢形成有效的DNA小沟烷基化剂。 。尽管由于不良的水溶性而受到阻碍,但是一些实例显示了体内抗缺氧肿瘤细胞的活性。在这里,我们研究了影响体外低氧选择性的结构性质,并表明对于高低氧选择性,硝基CBI应将A环上的H键供体容量的吸电子基团与次要的凹槽结合侧的碱性取代基结合起来链。在A形环上进行替换可与可改善水溶性的功能性引入相兼容。
