obtain 5-amidoisoxazoles. The novel compounds were screened in vitro as inhibitors of four human (h) isoforms of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1): hCA I, hCA II, hCA IV and hCA VII. The derivatives of the first series were shown to possess excellent inhibitory activity against the cytosolic isoform hCA II, an antiglaucoma drug target, with KIs in the range of 0.5-49.3nM and hCA VII,
通过使用常规方法和微波(MW)方法制备了两个系列的含苯磺酰胺的异恶唑化合物。在三乙胺的存在下,通过羟酰氯与2-氰基-N-(4-氨磺酰基苯基)乙酰胺的反应,合成了5-氨基-3-芳基-N-(4-氨磺酰基苯基)异恶唑-4-羧酰胺衍生物。使合成的5-氨基异恶唑与各种苯甲酰氯反应以获得5-酰胺基异恶唑。在体外筛选了作为金属酶碳酸酐酶的四种人(h)同工型抑制剂的新化合物(CA,EC 4.2.1.1):hCA I,hCA II,hCA IV和hCA VII。已显示第一系列的衍生物对胞浆亚型hCA II(一种抗青光眼药物的靶标)具有出色的抑制活性,KI的范围为0.5-49.3nM,hCA VII,
