4-substituted-spinaceamine (4,5,6,7-tetrahydro-imidazolo[4,5-c]pyridine) were prepared from histamine and aromatic aldehydes Schiff bases, and investigated as activators of four human (h) carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the cytosolic hCA I, II and VII, and the membrane-associated hCA IV. All isoforms were effectively activated by the new derivatives, and the nature of the moiety in position 4 of the
从组胺和芳香醛席夫碱制备了一系列4-取代的菠胺(4,5,6,7-四氢-咪唑并[4,5-c]吡啶),并研究了其为四种人(h)碳酸的活化剂酸酐酶(CA,EC 4.2.1.1)异构体,胞质hCA I,II和VII,以及与膜相关的hCA IV。新的衍生物有效地激活了所有同工型,并且双环系统第4位的部分的性质是影响针对所有同工型的激活特性的因素。对于hCA I,这些化合物的KAs在2.52-21.5 µM的范围内,最有效的活化剂是4-(2-羟苯基)-菠菜胺。对于hCA II,活化常数在0.60和17.2 µM之间,其中4-(2,3,5,6-四氟苯基)-菠菜胺是最好的活化剂。hCA IV的亲和力范围为0.52-63.8 µM,与hCA II相同的化合物是最有效的活化剂。对激活最敏感的同工型是与大脑相关的hCA VII,观察到的KA范围为82 nM-4.26 µM。有效的hCA VII激活剂是(2-溴苯基)-,2
