our previous work on the development of CB2 ligands, reporting the design and synthesis of a series of benzimidazole-containing derivatives that were explored as selective CB2 ligands with binding affinity towards both CB1 and CB2 receptors. Seven out of eighteen compounds exhibited preferential binding ability to CB2 over CB1 receptors with potencies in the sub-micromolar or low micromolar range. In
在这里,我们继续我们之前开发 CB2 配体的工作,报告了一系列含苯并咪唑衍生物的设计和合成,这些衍生物被探索为对 CB1 和 CB2 受体具有结合亲和力的选择性 CB2 配体。18 种化合物中有 7 种表现出对 CB2 优于 CB1 受体的优先结合能力,其效力在亚微摩尔或低微摩尔范围内。特别是,我们确定了两种有前途的热门化合物,激动剂 1-[2-( N , N - 二乙基氨基)乙基]-2-(4-乙氧基苄基)-5-三氟甲基苯并咪唑 ( 3 ) (CB2: K i = 0.42 μM)和反向激动剂/拮抗剂1-丁基-2-(3,4-二氯苄基)-5-三氟甲基苯并咪唑( 11 ) (CB2:K i = 0.37 μM)。还对文献中报道的其他苯并咪唑进行的对接研究支持了在这一系列化合物中观察到的构效关系,并允许确定这些衍生物显示的激动剂和/或反向激动剂行为中涉及的关键接触。ADMET 特性的计算机评估表
Synthesis and Biological Evaluation of Novel (thio)semicarbazone-Based Benzimidazoles as Antiviral Agents against Human Respiratory Viruses
with the 2-benzyl ring on the benzimidazole core structure, acted as dual inhibitors of influenza A virus and human coronavirus. For respiratory syncytial virus (RSV), activity is limited to the 5-thiosemicarbazone (25) and 5-hydrazone (22) compounds carrying the 2-[(benzotriazol-1/2-yl)methyl]benzimidazole scaffold. These molecules proved to be the most effective antiviral agents, able to reach the potency
