含ρ的γ-氨基丁酸A型受体(GABA A Rs)在控制视觉信号中起重要作用。因此,选择性靶向这些GABA A R的配体是令人关注的。在这项研究中,我们证明了部分GABA A R激动剂咪唑-4-乙酸(IAA)能够在体内穿透血脑屏障。我们制备了一系列的α-和N-烷基化以及IAA的双环类似物,以研究该支架的结构-活性关系,重点是IAA的乙酸侧链。通过IAA制备从化合物升通过有效最小步合成组氨酸,以及它们的药理学性质进行了表征在天然大鼠GABA甲Rs in a [3H]muscimol binding assay and at recombinant human α1β2γ2S and ρ1 GABAARs using the FLIPR™ membrane potential assay. The (+)‐α‐methyl‐ and α‐cyclopropyl‐substituted IAA analogues
A new type of carboxypeptidase a inhibitors designed using an imidazole as a zinc coordinating ligand
摘要:
2-(4-Imidazoyl)hydrocinnamic acid (1) and its congeners (2-4) having different length of alkyl chain spacers between the imidazole ring and the a-carbon to the carboxylate of 1 have been designed, synthesized and evaluated as inhibitors for carboxypeptidase A to show that they are competitive inhibitors for the enzyme. Inhibitor 1 was most potent having the K-i value of 0.8 mu M. The present study demonstrates that imidazole ring is an effective zinc coordinating ligand that can be useful for the design of inhibitors for zinc proteases. (C) 1997 Elsevier Science Ltd.
