analyses were performed on the synthesized series of compounds to investigate structure-activity relationships. Compounds 12, 32, and 49 of the carbamate, urea, and amide classes, respectively, showed the most suitable cytochrome inhibition and metabolic stability profiles. Among them, compound 12 showed excellent selectivity, solubility, and stability profiles as well as suitable in vitro and in vivo pharmacokinetic
代谢型谷氨酸受体5(mGlu5)的负变构调节剂(NAMs)对于治疗多种中枢神经系统疾病具有广阔的前景。最近,我们报道了丙-2-炔基亚环烷基胺衍生物是mGlu5受体的有效NAM和选择性NAM。在这项工作中,我们探索了丙-2-亚基亚环烷基胺化合物的酰胺,氨基甲酸酯,磺酰胺和脲衍生物,旨在提高溶解度和代谢稳定性。对合成的一系列化合物进行了计算机分析和实验分析,以研究结构-活性关系。氨基甲酸酯,尿素和酰胺类化合物的化合物12、32和49分别显示出最合适的细胞色素抑制和代谢稳定性特征。其中,化合物12表现出优异的选择性,溶解性,和稳定性概况以及合适的体外和体内药代动力学特性。它在大鼠和狗中被高度吸收,并在焦虑症,神经性疼痛和下尿路模型中活跃。
