determinant for improving biological activities and druglike properties of these molecules. Compounds with such modifications exhibited potent antiproliferative effects against breast and pancreatic cancer cell lines with IC50 values from low micromolar to nanomolar range. Among them, the newly discovered STAT3 inhibitor 12 (HJC0416) displayed an intriguing anticancer profile both in vitro and in vivo
在不断努力开发口服生物可利用小分子 STAT3 抑制剂作为人类癌症潜在治疗剂的过程中,一系列基于我们确定的先导化合物HJC0149 ( 1 )(5-氯-N-(1,1-二氧六环)的新型多样化类似物-1 H -1λ 6 -benzo [ b ]thiophen-6-yl)-2-hydroxybenzamide, Eur. J. Med. Chem . 2013 , 62 , 498–507) 已被合理设计、合成和药理学评估。分子对接研究和生物学特性支持我们早期的发现,即O羟基上的-烷基氨基侧链是改善这些分子的生物活性和药物特性的有效且必不可少的结构决定因素。具有此类修饰的化合物对乳腺癌和胰腺癌细胞系表现出有效的抗增殖作用,IC 50值从低微摩尔到纳摩尔范围。其中,新发现的 STAT3 抑制剂12 ( HJC0416 )在体外和体内(ip & po)都显示出有趣的抗癌特性。更重要的是,HJC04
