with the aim of identifying new anticancer agents. One of these compounds, which showed antiproliferative activity against resistant MCF-7 cell line, was selected as the hit structure. Replacement of the trimethoxybenzoyl moiety with a nicotinoyl group, in order to overcome solubility issues, led to a new series of N-biphenyl nicotinoyl anilides, among which a nitro derivative, N-(3',5'-difluoro-3-nitro-[1
筛选了许多以前作为渗透性糖蛋白(P-gp)调节剂研究过的三甲氧基苯甲酸酐,目的是鉴定新的抗癌药。选择对抗MCF-7细胞系具有抗增殖活性的这些化合物之一作为命中结构。为了克服溶解性问题,用烟酰基取代三甲氧基苯甲酰基部分导致了一系列新的N-联苯基烟酰基苯甲酰苯胺,其中包括硝基衍生物N-(3',5'-二氟-3-硝基- [1,1'-联苯] -4-基)烟酰胺(3)在纳摩尔范围内显示出对MCF-7和MDA-MB-231细胞的抗增殖活性。寻找硝基的生物等排体导致腈类似物N-(3-氰基-4'-氟-[1,1'-联苯] -4-基)烟酰胺(36),表明对MCF-7和MDA-MB-231细胞的活性大大增强。化合物36诱导了G2期和M期MCF-7细胞群体的剂量依赖性积累,并减少了S期细胞。相对于长春花碱(一种众所周知的有效抗有丝分裂剂),化合物36在低剂量(20-40 nm)下也能诱导G1期阻滞,但不抑制体外微管蛋白的聚合。
