We describe the synthesis of a series of novel 1-aroyl/acyl-3-(3-aminosulfonylphenyl) thioureas (4a–k) acting as human carbonic anhydrase (hCA, EC 4.2.1.1) inhibitors. Reaction of alkyl/aryl isothiocyanates with 3-aminobenzenesulfonamide afforded a series of the title compounds incorporating a variety of short as well as highly lipophilic long tails. The newly synthesized sulfonamides were evaluated
我们描述了一系列新型的1-芳酰基/酰基-3-(3-氨基磺酰基苯基)硫脲(4a-k)的合成,它们充当人类碳酸酐酶(hCA,EC 4.2.1.1)的抑制剂。烷基/芳基异硫氰酸酯与3-氨基苯磺酰胺的反应提供了一系列标题化合物,其结合了各种短的和高度亲脂的长尾巴。针对4种生理相关的CA同工型(hCA I,II,IV和IX)评估了新合成的磺酰胺。几种化合物表现出令人感兴趣的抑制活性。肿瘤相关的hCA IX是抑制这些化合物的最敏感同工型,K Is在21.5-44.0 nM范围内,对主要胞质亚型hCA II的选择性比在3.35-37.3范围内。结合了苯基乙酰基硫脲基和十五烷酰基硫脲基的磺酰胺是这项工作中检测到的最多的hCA IX选择性抑制剂,因此值得进一步研究。
