A series of diamide-coupled benzophenone, 2-(4-benzoyl-phenoxy)-N-2-[2-(4-benzoyl-phenoxy)-acetylamino]-phenyl}-acetamide analogues (9a-l) were synthesized by multistep reactions and all compounds were well characterized. Among the series (9a-l), compound 9k with three methyl groups at ortho position in rings A, B, and D and bromo group at the para position in ring E was selected as a lead compound
一系列二酰胺偶联的
二苯甲酮2-(4-苯甲酰基-苯氧基)-N- 2- [2-(2-(4-苯甲酰基-苯氧基)-乙酰
氨基]-苯基}-乙酰胺类似物(9a-1)的合成多步反应和所有化合物都得到了很好的表征。在系列(9a-1)中,通过对多种癌细胞类型进行筛选,选择了在环A,B和D的邻位具有三个甲基,在环E的对位具有
溴基的化合物9k作为先导化合物。体外细胞毒性和抗增殖测定系统。而且,化合物9k的细胞毒性性质导致体内肿瘤生长的退化,这可能是由于小鼠腹膜衬里血管生成减少导致肿瘤生长退化的缘故。
