我们发现氨基噻唑衍生物(E)-N-(5-苄基噻唑-2-基)-3-(呋喃-2-基)丙烯酰胺(1)具有很强的抗癌活性,并采取了蛋白质组学方法来鉴定化合物的目标蛋白1,输入蛋白β1(KPNB1)。使用荧光素标记的1进行的竞争性结合测定表明1具有对KPNB1的强结合亲和力(K d:〜20 n m)。此外,通过针对KPNB1,KPNA2,EGFR,ErbB2和STAT3的蛋白质印迹分析,我们确认了1对importin途径具有抑制作用。KPBN1似乎在几种癌细胞中过表达,并且siRNA诱导的KPNB1抑制作用显示出对癌细胞增殖的显着抑制作用,而使非癌细胞没有受到影响。因此,化合物1是开发KPNB1靶向抗癌药的有希望的新线索。荧光素标记的1可能是开发新型KPNB1抑制剂的有用定量探针。

2-4 In the course of searching for anticancer agents, 2-aminothiazolederivatives were recently prepared by varying the 2-amino position and the 5-substituted group of the 2-aminothiazole core in a high-speed parallel format using the procedure that was described in the literature. 5 The variations in the 5-position of the 2-amino-1,3-thiazole core were carried out though the condensation of thiourea
