A series of 3-amino-1,2,4-benzotriazine-1,4-dioxide derivatives 1 have been synthesized and evaluated for their cytotoxic activity in vitro against human leukemia cell lines: Molt-4, K562, HL60, human liver cancer cell Hep-G2, human prostate cancer cell PC-3 in hypoxia. Most of the compounds showed more potent activity than TPZ. Compounds 1i and 1m displayed encouraging superior activity against Molt-4
合成了一系列3-氨基-1,2,4-苯并三嗪-1,4-二氧化物衍生物1并评估了其对人白血病细胞系Molt-4,K562,HL60,人肝癌的体外细胞毒活性细胞Hep-G2,缺氧的人前列腺癌细胞PC-3。大多数化合物显示出比TPZ更强的活性。化合物1i和1m对Molt-4和HL-60细胞系显示出令人鼓舞的优异活性。三种潜在的衍生物接受了针对Molt-4和HL-60细胞系的低氧和常氧活性测试,并显示出明显的低氧选择性。进一步的机理研究表明,化合物1i和1k在Molt-4细胞中的细胞毒活性可能是通过调节p53蛋白表达和线粒体膜电位(DeltaPsi(m))来介导的。
