产品描述
BEZ235是一种咪唑喹啉衍生物,抑制PI3K和mTOR激酶的活性,具有低纳摩尔浓度的IC50值。在临床前动物研究以及临床试验中,BEZ235有很好的耐受性,具有可控制的胃肠道副作用[1, 2]。BEZ235与ATP竞争结合激酶的ATP结合位点,可逆的降低酶活性,导致肿瘤细胞停滞在G1期[1]。除了抑制细胞生长,BEZ235还可以阻断VEGF诱导的血管生成[3]。BEZ235也可能抑制DNA-PKcs[4]。
BEZ235在体外和体内具有潜在的抗肿瘤活性。BEZ235抑制不依赖于PI3K途径突变的多个肿瘤细胞系的生长[5]。在异种移植小鼠模型中,BEZ235阻断PI3K信号,具有抗肿瘤活性[1, 5]。组合研究表明,BEZ235可以增强temozolomide的功效[1]。
临床数据表明BEZ235具有抗肿瘤活性,尤其是在PI3K信号通路失调的癌症患者中。BEZ235单独给药或与其他药剂组合给药被用于多个临床试验中。
