摘要
Src与iNOS为肿瘤发生、转移中位于不同通路的重要靶酶,本文采用分子拼合的药物设计原理,设计合成了全新的酪氨酸Src蛋白激酶与iNOS的双重抑制剂。所设计合成的化合物经过Src激酶和iNOS的抑制活性检测及体外抗肿瘤测试,实验结果表明大部分化合物对于两种靶酶均表现出一定的抑制活性,部分化合物对于多种肿瘤细胞的增殖有一定的抑制作用。其中化合物33对Src激酶和iNOS均有比较好的抑制活性,对于肝癌HepG2和结肠癌HT-29细胞的增殖也有明显的抑制作用。
Because c-Src and iNOS are key regulatory enzymes in tumorigenesis, a new series of 4-heterocycle amine-3-quinolinecarbonitriles as potent dual inhibitors of both enzymes were designed, synthe-sized and evaluated as multiple targets agents in cancer therapy. All compounds were evaluated by two related enzyme inhibition assays and an anti-proliferation assay in vitro. The results showed that most compounds inhibited c-Src and iNOS well. The best compound 33 inhibited both enzymes with the IC50 values of 0.048 4μmol·L^-1 and 34.5μmol·L^-1, respectively. Some of the compounds also showed moderate anti-proliferation activities at 10μmol·L^-1 against colon cancer HT-29 and liver cancer HepG2 cell lines.
