Mono- and dihalogenated histamine derivatives incorporating fluorine, chlorine and bromine have been prepared together with the corresponding boc-protected compounds at the aminoethyl group. They have been investigated as activators of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). The cytosolic human (h) isoforms hCA I and II were moderately activated by the boc-protected halogenated histamines
掺入氟、氯和溴的单卤代和二卤代组胺衍生物与相应的氨基乙基上的 boc 保护化合物一起制备。它们已被研究作为锌酶碳酸酐酶(CA、EC 4.2.1.1)的激活剂。胞质人 (h) 亚型 hCA I 和 II 被 boc 保护的卤化组胺中度激活,并且被去保护的组胺非常有效地激活。首次检测到低纳摩尔和亚纳摩尔 hCA I 和 II 激活剂,以组胺为先导,其对异构体 I 的亲和力为 2μM,对 hCA II 的亲和力为 125μM。
