identified from 372 thiazolidinone analogues by applying iterative library approaches. These compounds selectively killed both non-small cell lung cancer cell line H460 and its paclitaxel-resistant variant H460 taxR at an IC 50 between 0.21 and 2.93 microM while showing much less toxicity to normal human fibroblasts at concentrations up to 195 microM. Structure-activity relationship studies revealed that
通过应用迭代文库方法,已从372噻唑烷酮类似物中鉴定出十种细胞选择性化合物。这些化合物在0.250和2.93 microM之间的IC 50选择性杀死了非小细胞肺癌细胞系H460及其抗紫杉醇的变体H460 taxR,同时在高达195 microM的浓度下对正常人成纤维细胞的毒性大大降低。结构-活性关系研究表明:(1)4-噻唑烷酮环(图1中的环B)上的氮原子不能被取代;(2)环A上的多个取代在各个位置都可以容忍;(3)取代环C上的C 1 -C 4基团限于-NMe 2基团。来源于活性分子的药效基团表明,两个氢键受体和三个疏水区是共同的特征。
