discovery of new sulfonate and sulfamate derivatives of benzofuran- and benzothiophene as potent inhibitors of human carbonic anhydrases (hCAs) II, IX and XII. A set of derivatives, 1a-t, having different substituents on the fused benzofuran and benzothiophene rings (R = alkyl, cyclohexyl, aryl, NH2, NHMe, or NMe2) was designed and synthesized. Most of the derivatives exhibited higher potency than acetazolamide
在当前的工作中,我们报告发现了作为人碳酸酐酶(hCAs)II,IX和XII的有效抑制剂的新的苯并呋喃和苯并噻吩的磺酸盐和氨基磺酸衍生物。设计并合成了一组在稠合的苯并呋喃和苯并噻吩环上具有不同取代基的衍生物1a-t(R =烷基,环己基,芳基,NH2,NHMe或NMe2)。大多数衍生物作为纯化的hCAII,IX和XII同工型的抑制剂,其表现出比乙酰唑胺更高的效价。最有效的hCAII,hCAIX和hCAXII抑制剂为1g,1b和1d,IC50±SEM值分别为0.14±0.03、0.13±0.03和0.17±0.06 µM。此外,化合物1d和1n对hCAXII同工酶具有良好的抑制作用。
