assayed as inhibitors of several carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the cytosolic CA I and II, the membrane-associated CA IV and the mitochondrial CA VA and VB. The new compounds showed weak inhibitory activity against hCA I (K(I)s of 102 nM-7.42 microM), hCA II (K(I)s of 0.54-7.42 microM) and hCA IV (K(I)s of 4.32-10.05 microM) but were low nanomolar inhibitors of hCA VA and hCA VB, with
制备了一系列2-取代的1,3,4-噻二唑-5-磺酰胺,并作为几种碳酸酐酶(CA,EC 4.2.1.1)同工型的抑制剂,即胞质CA I和II,膜相关CA IV和线粒体CA VA和VB。新化合物显示出对hCA I(K(I)s为102 nM-7.42 microM),hCA II(K(I)s为0.54-7.42 microM)和hCA IV(K(I)s为4.32-)的弱抑制活性。 10.05 microM),但是hCA VA和hCA VB的低纳摩尔抑制剂,抑制常数分别为4.2-32 nM和1.3-74 nM。此外,抑制线粒体酶对CA II的选择性比在67.5-415范围内,使这些磺酰胺成为第一个选择性CA VA / VB抑制剂。
