This work described a novel “functional hybrid” design for bis-tetrahydroisoquinoline (bis-THIQ) analogues as potential DNA alkylation agents by replacing the labile C21-carbinolamine on the bis-THIQ skeleton of ET-743 with a chemically stable cyclic N,O-aminal functionality. In vitro anti-proliferation evaluation has proven that it is a successful approach to deliver new bis-THIQ analogues with common
这项工作描述了双
四氢异喹啉 (bis-THIQ) 类似物作为潜在 DNA 烷基化剂的新型“功能杂合”设计,通过用
化学稳定的环状N 、 O取代 ET-743 双-THIQ 骨架上不稳定的 C21-
甲醇胺-
氨基功能。体外抗增殖评估已证明,这是一种成功的方法,可提供具有常见细胞毒性的新型 bis-THIQ 类似物,其中几种对人癌
细胞系 A549、HepG2 和
MDA 的增殖表现出亚微摩尔范围的 IC 50分别为-MB-231。
