We reported the synthesis, hypoxic cytotoxic activities and selectivities of 18 new 3-(alkoxymethylamino)-1,2,4-benzotriazine 1,4-dioxides. The synthesized compounds were screened in vitro against 5 cell lines: K562, SMMC-7721, A549, PC-3 and KB in hypoxia and in normoxia. Some of them showed higher or similar cytotoxic activity when compared to tirapazamine. Physico-chemical study showed the positive
我们报道了18种新的3-(烷氧基甲基氨基)-1,2,4-苯并三嗪1,4-二氧化物的合成,低氧的细胞毒性活性和选择性。在缺氧和常氧条件下,针对5种细胞系(K562,SMMC-7721,A549,PC-3和KB)进行体外筛选。与替拉帕明相比,其中一些表现出更高或相似的细胞毒活性。理化研究表明,低氧活性与亲脂性在一定范围内呈正相关。对有效衍生物4b,4l和4m的初步机理研究表明,这些化合物的细胞毒性活性可能是通过诱导细胞凋亡来介导的。
