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.

inhibitors starting from of 1H-imidazol-4-ylacetic acid with the carboxylic acid side chain originating from different positions and varying in length have been synthesized and tested for the inhibitory potency at the four GABA uptake transporters mGAT1–4 stably expressed in HEK cells. Further two bicyclic compounds with a rigidified carboxylic acid side chain were included in this study. The results of the
A novel class of imidazo heterocyclic compounds, pharmaceutical compositions comprising them and use thereof in the treatment and/or prevention of diseases and disorders related to the histamine H3 receptor. More particularly, the compounds are useful for the treatment and/or prevention of diseases and disorders in which an interaction with the histamine H3 receptor is beneficial.
