anticancer potential, four new pyrazolo[1,2-a]benzo[1,2,3,4]tetrazinone derivatives, designed through the chemometric protocol VLAK, and three of the most active compounds of the previous series have been evaluated on some cellular events including proliferation, apoptosis induction, and cell cycle. The NCI one dose (10 μM) screening revealed that the 8,9-di-methyl derivative showed activity against Leukemia
为了研究它们的抗癌潜力,通过化学计量学方法VLAK设计了四种新的吡唑并[1,2- a ]苯并[1,2,3,4]四嗪酮衍生物和先前系列中活性最高的三种化合物评估了一些细胞事件,包括增殖,凋亡诱导和细胞周期。NCI一剂(10μM)筛选显示8,9-二甲基衍生物显示出对白血病(CCRF-CEM)和结肠癌细胞系(COLO 205)的活性,分别达到了81%和45%的生长抑制(GI) ), 分别。用两个氯原子取代两个甲基可维持对白血病细胞的活性(CCRF-CEM,GI 77%),并选择性增强针对COLO 205的活性,达到LD 50在μM范围内,相对于SW-620,GI为77%。有趣的是,观察到针对治疗性“难治性”非小细胞肺癌(NCI-H522)的可观的47%的生长抑制。此外,基于线粒体膜去极化的凋亡诱导作用被发现在HeLa细胞的EC 50 3–5μM范围内,证明与相关的体外存在明确的关系。针对NCI肿
