Two novel series of phenylacrylamide linked coumarins and sulfocoumarins (6a-p, 8a-i, and 14a-g) were synthesized and evaluated against four physiologically relevant human carbonic anhydrases (hCAs, EC 4.2.1.1), isoforms hCA I, hCA II, hCA IX and hCA XII for their inhibitory action. All new compounds when screened for carbonic anhydrase inhibitory activity have shown selective inhibition towards the
两种新型系列苯基丙烯酰胺连接的香豆素和sulfocoumarins(的图6a-P ,8A- i和14A-G )的合成和对四名生理学相关的人类碳酸酐酶(HCAS,EC 4.2.1.1)来评价,同种型HCA I,II HCA, hCA IX和hCA XII具有抑制作用。当筛选碳酸酐酶抑制活性时,所有新化合物均显示出相对于CA I和II对与肿瘤相关的同工型hCA IX和XII的选择性抑制,抑制常数在亚微摩尔至低纳摩尔范围内。化合物6b和14g对hCA IX表现出显着的抑制作用,纳摩尔浓度低,而6k对hCA XII有效。化合物基于新的作用机理,图6b,14g和6k可以被认为是用于癌症治疗的未来发展的先导分子。
