  Carbonic anhydrase inhibitors: Synthesis and inhibition of the human carbonic anhydrase isoforms I, II, VII, IX and XII with benzene sulfonamides incorporating 4,5,6,7-tetrabromophthalimide moiety

  摘要：

  A series of 4,5,6,7-tetrabromo-1,3-dioxoisoindolin-2-yl benzenesulfonamide derivatives (compounds 1-8) was synthesized by reaction of benzene sulfonamide derivatives with 4,5,6,7-tetrabromophthalic anhydride moiety. These new sulfonamides were investigated as inhibitors of the zinc metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) and more specifically against the human (h) cytosolic isoforms hCA I, II and VII and the transmembrane tumor-associated isoform hCA IX and XII. The new compounds were good hCA I inhibitors (Kis in the range of 143 to >10,000 nM), but were moderately effective, as hCA II inhibitors (Kis of 47-190 nM) and poor hCA VII inhibitors (Kis in the range of 54-175 nM) compared to acetazolamide. The tumor-associated hCA IX was effectively inhibited with Kis ranging between 8.5 and 234 nM and hCA XII with inhibition constants in the range of 6.1-197 nM with high selectivity ratio. The structure-activity relationship (SAR) with this series of sulfonamides is straightforward, with the main features leading to good activity for each isoforms being established. The high sequence hCA alignment homology and molecular docking study of compounds was performed to rationalize the SAR reported over here. (C) 2013 Elsevier Ltd. All rights reserved.

  新型3-溴磺酰胺酰基硫脲衍生物的合成：脲酶抑制及其分子对接研究

  摘要：

  在这项工作中，通过溴化磺酰胺与芳香酸反应形成异硫氰酸酯，设计并合成了基于3-溴磺酰胺基酰基硫脲(4a-j)的具有治疗活性的抗脲酶药物，并使用FT-IR、1HNMR、 13 C NMR和MS分析。筛选新制备的化合物用于体外脲酶抑制测定。与标准硫脲相比，具有未取代苯基的衍生物4a对脲酶的 IC 50值为 17.02 ± 0.011 (IC 50 = 21 ± 0.12 µM)。构效关系（SAR）揭示苯环上取代基的电子和位置效应对于临床重要酶的抑制起着重要作用。此外，进行的计算机研究表明，这些化合物与脲酶结合位点的关键残基表现出极性和非极性相互作用。体外和计算机研究根据动力学和对接结果一致，表明合成的基于 3-溴磺酰胺的酰基硫脲衍生物可能作为发现新脲酶抑制剂的潜在成果。

  anhydrides. These sulphonamides were investigated as human carbonic anhydrases (hCAs, EC 4.2.1.1) I, II, IX, and XII inhibitors. hCA I was inhibited with inhibition constants (Kis) ranging from 49 to >10,000 nM. The physiologically dominant hCA II was significantly inhibited by most of the sulphonamide with the Kis ranging between 2.4 and 4515 nM. hCA IX and hCA XII were inhibited by these sulphonamides

  A series of 4,5,6,7-tetrachloro-1,3-dioxoisoindolin-2-yl benzenesulfonamide derivatives (compounds 1-8) was synthesized by reaction of benzene sulfonamides incorporating primary amino moieties with 4,5,6,7-tetrachlorophthalic anhydride. These sulfonamides were assayed as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1). Some of these compounds showed very good in vitro human carbonic anhydrase (hCA) isoforms I, II and VII inhibitory properties, with affinities in the low nanomolar range. Inhibition activities against hCA I were in the range of 159-444 nM; against hCA II in the range of 2.4-4515 nM, and against hCA VII in the range of 1.3-469 nM. The structure-activity relationship (SAR) with this series of sulfonamides is straightforward, with the main features leading to good activity for each isoform being established.
