  名称：

  Carbonic anhydrase inhibitors. Regioselective synthesis of novel 1-substituted 1,4-dihydro-4-oxo-3-pyridinesulfonamides and their inhibition of the human cytosolic isozymes I and II and transmembrane cancer-associated isozymes IX and XII

  摘要：

  A series of 1-substituted 1,4-dihydro-4-oxo-3-pyridinesulfonamide (2-16) have been synthesized and investigated as inhibitors of four isoforms of zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), that is the cytosolic ubiquitous CA I and II, and cancer-associated isozymes CA IX and XII. Against the human isozymes hCA I the new compounds showed inhibition constants in the range of 1.09-12.1 mu M, against hCA II in the range of 50.5-172 nM, against hCA IX in the range of 5.2-118 nM, and against hCA XII in the range of 8.7-381 nM, respectively. Compounds 2, 3, 5-9, 11, 13 and 14 showed excellent hCA IX inhibitory efficacy, with K(I)s = 5.2-11.0 nM, being much more effective as compared to the clinically used sulfonamides AAZ, MZA, EZA, DCP and IND (K(I)s = 24-50 nM). Compounds 2, 3, 5-9, 11 and 13 were also very effective hCA XII inhibitors (K(I)s = 8.7-45.2 nM) which are comparable or more effective than those clinically used EZA and DCP (K(I)s = 22 and 50 nM), respectively.

  The reactions of 4‐substituted 3‐pyridinesulfonamides 1a, 1b, 1c, 1d, 1e with benzenesulfonyl chlorides 2a, 2b, 2c, 2d, 2e, 2f in acetonitrile were investigated. Depending on the structure of arylsulfonyl chlorides and the reaction conditions the following four types of products were obtained in good yields: 3‐sulfamoyl‐4‐R‐1‐arylpyridinium chlorides 3, 4, 5, 6, 7, 8; 1,10‐bis(3‐nitrobenzenesulfonylimino)deca‐2
