1-c][1.4]benzodiazepine system, a series of 11-aryl-5H-imidazo[2,1-c][1,4]benzodiazepines (3a-i) and their 10,11-dihydro-derivatives (4a-i) has been synthesized. The synthetic strategy includes the preparation of the aryl-[1-(2-nitrobenzyl)-1H-imidazol-2-yl]methanones (5a-i) followed by their reduction and subsequent cyclization. Affinities of compounds 3a-i and 4a-i for central benzodiazepine as well
在旨在阐明5H-咪唑并[2,1-c] [1.4]苯并二氮杂系统性质的研究计划的背景下,一系列11-芳基-5H-咪唑并[2,1-c] [1,已经合成了4]苯并二氮杂卓(3a-i)及其10,11-二氢衍生物(4a-i)。合成策略包括制备芳基-[1-(2-硝基苄基)-1H-咪唑-2-基]甲酮(5a-i),然后将其还原并随后环化。通过放射性配体结合测定法确定化合物3a-1和4a-1i对中心苯并二氮杂well以及腺苷A1-受体的亲和力。在不饱和类似物中,两个受体的最高活性由1H-(2-噻吩基)衍生物3e表示。氢化类似物4a-i对中央苯并二氮杂或腺苷A1-受体均未表现出明显的结合亲和力。
