The synthesis and antitumor activity in normoxic and hypoxic conditions of a series of pyrazolo[5,1-c][1,2,4]benzotriazine and its related analogues are reported. All compounds were tested on human colorectal adenocarcinoma cell line HCT-8 and for compounds 15 and 20, which show to have selective cytotoxicity in hypoxic and in normoxic conditions respectively, ROS production, cell cycle, and DNA fragmentation
报道了一系列吡唑并[5,1-c] [1,2,4]苯并三嗪及其相关类似物在常氧和低氧条件下的合成和抗肿瘤活性。所有化合物均在人大肠腺癌细胞系HCT-8和化合物15和20上进行了测试,化合物15和20在低氧和常氧条件下分别显示出选择性的细胞毒性,测定了ROS的产生,细胞周期和DNA片段化。这项初步研究鼓励我们将15和20视为进一步优化的有趣线索。
