General description

替莫唑胺(Temozolomide)是一种小分子的亲脂性烷化剂。在DNA中与亲核微环境（鸟嘌呤残基）产生共价作用，因此替莫唑胺具有细胞毒性。替莫唑胺的作用机制是通过水解DNA，导致DNA降解并破坏肿瘤细胞。替莫唑胺对恶性神经胶质瘤细胞的主要作用是令G2/ M细胞周期停滞，偶尔使细胞凋亡。替莫唑胺是一种DNA甲基化剂和耐药修饰剂；抗肿瘤和抗血管生成。替莫唑胺诱导G2/M阻滞和凋亡，原理是其通过基因组DNA中一个甲基基团内收至鸟嘌呤的O6位置，以及碱基切除修复(BER)途径中DNA修复蛋白O(6)-烷基鸟嘌呤DNA烷基转移酶(AGT)的功能失活。

Application

替莫唑胺已用于分析胶质母细胞瘤细胞系的耐药机制。替莫唑胺已用于诱导胶质母细胞瘤细胞的细胞毒性作用，以研究蛋白二硫化物异构酶(PDI)的抑制作用。
