The results revealed that most of the compounds showed good activity against hCA II, IX, and XII whereas none of them were active against hCA I (Ki >100 μM). It is observed that the physiologically most important cytosolic isoform hCA II was inhibited by these molecules in the range of Ki 9.3–77.7 μM. It is also found the both the transmembrane isoforms hCA IX and XII were also inhibited with Kis ranging
已经合成并开发了一系列新型的2-吗啉代-4-苯基噻唑-5-基丙烯酰胺衍生物(8a – s),作为一种非磺酰胺类碳酸酐酶(CA,EC 4.2.1.1)抑制剂。以乙酰唑胺(AAZ)为标准药物,评估了新合成的分子对四种同工型的CA抑制能力:胞质同工酶hCA I,II以及跨膜肿瘤相关同工型hCA IX和hCA XII。结果表明,大多数化合物对hCA II,IX和XII均显示出良好的活性,而它们均对hCA I没有活性(K i > 100μM)。据观察,在K i范围内,这些分子抑制了生理上最重要的胞质亚型hCA II。9.3–77.7μM。还发现跨膜同工型hCA IX和XII也分别被K i s抑制,范围在54.7–96.7μM和4.6–8.8μM之间。通过对接研究评估了hCA II,IX和XII催化口袋中活性化合物的结合方式。与hCA I同工型相比,这种新的非hCA II,IX和XII的选择性抑制剂
