the focus of this study where a series of novel 4-anilino-furo[2,3-d]pyrimidine derivatives was designed, synthesized and biologically evaluated. Modification of the solvent accessible 5-position side chain greatly affected the in-vitro EGFR/HER2 inhibitory activity. Three derivatives bearing 5-carboxylic acid side chain, namely the 3-chloroanilino derivative (8c), the 3-bromoaniline (8d) and the lapatinib
EGFR(表皮生长因子受体)和HER2(人类表皮生长因子受体2)负责多种癌症的发生,是本研究的重点,其中一系列新颖的4-苯胺基-呋喃[2,3- d ]设计,合成并进行了嘧啶衍生物的生物学评估。溶剂可及的5位侧链的修饰极大地影响了体外EGFR / HER2抑制活性。带有5-羧酸侧链的三个衍生物,即3-氯苯胺基衍生物(8c),3-溴苯胺(8d)和拉帕替尼类似物(10)表现出最显着的亚微摩尔EGFR抑制作用。令人惊讶的是,体外酯7h及其酸类似物10的分析显示结果分别对A549细胞系(IC 50 0.5和21.4μM)的抗增殖活性与EGFR抑制活性(18%和100%)之间存在显着差异,表明7h可能对做10的前药。体内结果也证实了这一假设,其中针对EAC(艾氏腹水癌)实体瘤模型的体内抗肿瘤评估显示7h和8d(10 mg / kg剂量)的抗肿瘤活性与吉非替尼在相同剂量下的抗肿瘤活性相当,分别具有67%
