efforts towards developing novel carbonic anhydrase inhibitors based on the isatin moiety, herein we report the synthesis and biological evaluation of novel sulfonamides (5a-h, 10a-g and 11a-c) incorporating substituted 2-indolinone moiety (as tail) linked to benzenesulfonamide (as zinc anchoring moiety) through a hydrazide linker. The synthesized sulfonamides were evaluated in vitro for their inhibitory
正如我们对基于所述靛红部分开发新颖的碳酸酐酶抑制剂正在进行的努力的一部分,在此我们报告的合成和新颖的磺酰胺(生物评价5A-H ,10A-G和图11A-C )将取代的2-吲哚满酮部分( (如尾巴)通过酰肼连接基与苯磺酰胺(作为锌锚定部分)相连。体外评估了合成的磺酰胺类对下列人类(h)碳酸酐酶(hCA,EC 4.2.1.1)同工型hCA I,II,IX和XII的抑制活性。所有这些同工型均受到本文报道的磺胺类药物不同程度的抑制。hCA I被K I抑制s在671.8:3549.5 nM的范围内,hCA II在36.8:892.4 nM的范围内; hCA IX的范围为8.9:264.5 nM,而hCA XII的范围为9.0:78.1 nM。尤其是,化合物10b以一位数的纳摩尔hCA IX和XII抑制剂(分别为8.9和9.2 nM)出现。在hCA II,IX和XII活性位点内对化合物10b进行的分子对接研究使我们能够合理化获得的抑制结果。
