The synthesis and SAR of a novel 3-benzazepine series of 5-HT2C agonists is described. Compound 7d (lorcaserin, APD356) was identified as one of the more potent and selective compounds in vitro (pEC50 values in functional assays measuring [(3)H]phosphoinositol turnover: 5-HT2C = 8.1; 5-HT2A = 6.8; 5-HT2B = 6.1) and was potent in an acute in vivo rat food intake model upon oral administration (ED50
描述了新型3-苯并ze庚因系列的5-HT 2C激动剂的合成和SAR。在体外,化合物7d(lorcaserin,APD356)被鉴定为更有效和选择性的化合物之一(在功能测定中,通过[[3] H]磷酸肌醇周转率测定的pEC50值:5-HT2C = 8.1; 5-HT2A = 6.8; 5- HT2B = 6.1),并且在口服后在急性体内大鼠食物摄入模型中有效(在6 h时的ED50 = 18 mg / kg)。Lorcaserin在大鼠单剂量药代动力学研究中进一步表征(t1 / 2 = 3.7小时; F = 86%),以及在生长的Sprague-Dawley大鼠中28天的体重增加模型(在60℃时观察到体重增加减少8.5%) 36 mg / kg出价)。选择洛卡西林在肥胖症的临床试验中进行进一步评估。
