A series of potential new 5-HT2 receptor scaffolds based on a simplification of the clinically studied, 5-HT2CR agonist vabicaserin, were designed. An in vivo feeding assay early in our screening process played an instrumental part in the lead identification process, leading us to focus on a 6,5,7-tricyclic scaffold. A subsequent early SAR investigation provided potent agonists of the 5-HT2C receptor that were highly selective in both functional and binding assays, had good rat PK properties and that significantly reduced acute food intake in the rat.

在功能和结合测定中发现了具有高选择性的有效苯并二氮杂卓5-HT2C受体激动剂的先导系列。

根据简化的临床研究，设计了一系列潜在的新型5-HT2受体支架5-HT2CR激动剂vabicaserin。在筛选过程的早期，体内喂养试验在铅识别过程中发挥了重要作用，使我们专注于6,5,7-三环支架。随后的早期SAR研究提供了有效的5-HT2C受体激动剂，该激动剂在功能和结合测定中具有高度选择性，具有良好的大鼠PK特性，并显着降低了大鼠的急性食物摄入量。
