compounds were investigated as inhibitors of carbonic anhydrases (CA, EC 4.2.1.1), and more precisely cytosolic isoforms hCA I, II, VII and membrane-bound one hCA IV. All investigated isoforms were inhibited in low micromolar and nanomolar range by the new compounds. hCA IV and VII were inhibited with KIs in the range of 29.7–708.8 nM (hCA IV), and of 1.3–90.7 nM (hCA VII). For hCA I and II the KIs were in
在微波下,将4-氨基-N-(5-氨磺酰基-1,3,4-噻二唑-2-基)苯甲酰胺与环1,3-二酮(二甲酮和环己烷-1,3-二酮)和芳香醛缩合辐射,导致一系列of啶-乙酰唑酰胺共轭物。研究了这些新化合物作为碳酸酐酶的抑制剂(CA,EC 4.2.1.1),更确切地说是胞质异构体hCA I,II,VII和膜结合的hCA IV抑制剂。新化合物可在低微摩尔和纳摩尔范围内抑制所有研究的同工型。hCA IV和VII被K I抑制的范围为29.7–708.8 nM(hCA IV)和1.3–90.7 nM(hCA VII)。对于hCA I和II,K Is的范围为6.7–335.2 nM(hCA I)和0.5–55.4 nM(hCA II)。描绘了此处报道的for啶-乙酰唑酰胺缀合物抑制这些同工型的构效关系(SAR)。
