residues. All the compounds were further screened in vitro for anticancer activity and found that compound 8 and 11 exhibit considerable anticancer activity against MCF-7 and HepG-2 cell lines. All these findings suggest that compound 8 and 11 may be further exploited as a novel pharmacophore model for the development of anticancer agents.
为了获得新型的人类碳酸酐酶IX(CAIX)抑制剂,合成了一系列吡啶-噻唑烷酮衍生物,并通过各种光谱技术对其进行了表征。通过CAIX的酯酶测定,通过荧光结合研究和酶抑制活性来测量化合物的结合亲和力。观察到化合物8和11分别以IC 50值为1.61μM和1.84μM显着抑制CAIX活性。化合物8和11对CAIX的结合亲和力非常高,其K D值分别为11.21μM和2.32μM 。对接研究表明,化合物8和11通过形成足够数量的氢键和与活性侧残基的范德华相互作用,有效地结合在CA IX的活性位腔中。在体外进一步筛选了所有化合物的抗癌活性,发现化合物8和11对MCF-7和HepG-2细胞系显示出显着的抗癌活性。所有这些发现表明,化合物8和11可以进一步用作开发抗癌剂的新型药效团模型。
