Description |
RS-102221 hydrochloride is a selective 5-HT2C receptor antagonist (Ki=10 nM). RS-102221 hydrochloride shows nearly 100-fold selectivity for the 5-HT2C receptor as compared to the 5-HT2A and 5-HT2B receptors. RS-102221 hydrochloride can promote the differentiation of new nerve cells. RS-102221 hydrochloride increases food-intake and weight-gain in rats[1][2].

In Vitro |
RS102221 (0.3-300nM; 24 h) 促进小鼠成年海马神经前体细胞 (ahNPCs) 分化,并显著增加 MAP-2+ 细胞的百分比[1]。 Cell Differentiation Assay[1] Cell Line: Mouse adult hippocampal neural progenitor cells (ahNPCs) Concentration: 0.3, 1, 10, 30, 100, and 300 nM Incubation Time: 24 hours Result: Significantly increases the percentage of MAP-2+ cells at 10 nM.

In Vivo |
RS-102221 hydrochloride (2 mg/kg; 腹腔注射; 每天 1 次, 共 14 天) 增加大鼠的食物摄入量和体重增加[2]。 RS-102221 hydrochloride (2 mg/kg; 腹腔注射; 单次剂量) 与 3,4-亚甲基二氧基-N-甲基苯丙胺 (MDMA 或“摇头丸”) 联合施用于小鼠,可在前 1 小时抑制 MDMA 诱导厌食症,和 MDMA 诱导的过度运动[3]。 RS-102221 hydrochloride (2 mg/kg; 腹腔注射; 单次剂量) 可减轻小鼠在光暗试验中的焦虑,并降低惊吓反射的幅度[4]。
