Forty seven thieno[2,3-b]pyridines-2-carboxamides, furo[2,3-b]pyridines-2-carboxamides and tetrahydrothieno[2,3-b]quinolones-2-carboxamides derivatives were synthesized and tested for their antiproliferative activity against the NCI-60 cell lines. The 5-keto-tetrahydrothieno[2,3-b]quinolones-2-carboxamides (series 17) were found to have the greatest activity, with the compound containing a 3-methoxyphenylcarboxamide
合成了47种噻吩并[2,3 - b ]吡啶-2-羧酰胺,呋喃并[2,3 - b ]吡啶-2-甲酰胺和四氢噻吩并[2,3 - b ]喹诺酮-2-羧酰胺衍生物,并对其进行了测试。对NCI-60细胞系的抗增殖活性。发现5-酮-四氢噻吩并[2,3- b ]喹诺酮-2-羧酰胺(系列17)活性最高,其中含有3-甲氧基苯基羧酰胺(化合物17d)的化合物活性最高,GI 50对一系列细胞系,特别是黑素瘤细胞系MDA-MD-435(GI 50– 23 nM)和乳腺癌细胞系MDA-MB-468(GI 50 – 46 nM)。针对磷酸肌醇特异性磷脂酶C的系列17的分子模型揭示,氨基酸His356,Glu341,Arg549和Lys438的侧链参与与配体的氢键结合,并且亲脂性口袋被苯基羧酰胺部分占据。
