The aberrant level of the carbonic anhydrase isozymes is linked with various disorders which include glaucoma, epilepsy, altitude sickness and obesity. In the present study, a series of the pyrazole-based benzene sulfonamides derivatives (4a–4l) were designed, synthesized and evaluated as the inhibitors of the three isoforms of human carbonic anhydrases (hCAII, hCAIX and hCAXII). A number of the derivatives
碳酸酐酶同工酶的异常水平与多种疾病有关,包括青光眼、癫痫、高原反应和肥胖。在本研究中,设计、合成了一系列基于吡唑的苯磺酰胺衍生物(4a-4l ),并对其作为人碳酸酐酶三种亚型(hCAII、hCAIX和hCAXII)的抑制剂进行了评估。发现许多衍生物比用作人 hCAII、hCAIX 和 hCAXII 标准品的乙酰唑酰胺更具活性。该系列中,化合物4k将hCAII抑制至亚微摩尔水平,IC 50 ± SEM浓度为0.24 ± 0.18 μM,抑制剂4j将hCAIX的活性降低至IC 50± SEM 等于 0.15 ± 0.07 μM,而分子4g在 IC 50浓度低至0.12 ± 0.07 μM 时就阻断了同工酶 hCAXII 的催化潜力。此外,与 hCAIX 和 hCAXII 相比,化合物 4e 和 4k 被筛选为异构体 hCAXII 的优先抑制剂,最大浓度的一半分别为 0.75 ± 0.13 μM
