side (RHS, benzene ring) in the 'first generation' beta3-AR agonists BRL 37344 and CL 316243 with a 1H-indole ring gave compound 31 with unique pharmacological properties among beta3-AR agonists. Initial in vitro assays showed that 31 possesses modest rat and human beta3-ARs agonistic activity. Introduction of various substituent into the indole nucleus of 31 afforded a number of compounds with good beta3-ARs
为了寻找有效和选择性的β3-肾上腺素能受体(β3-AR)激动剂作为治疗II型糖尿病和肥胖症的潜在药物,制备了一系列新的1-(3-氯苯基)-2-氨基乙醇衍生物,并对其进行了评估。它们在中国仓鼠卵巢(CHO)细胞中表达的对人beta1,beta2和beta3-ARs和大鼠beta3-AR的生物学活性。用1H-吲哚环取代“第一代”β3-AR激动剂BRL 37344和CL 316243中的右手侧(RHS,苯环),使化合物31在β3-AR激动剂中具有独特的药理特性。最初的体外试验表明,31种大鼠和人beta3-ARs具有中等激动作用。将各种取代基引入到31的吲哚核中,提供了许多具有良好的β3-ARs激动活性的化合物。特别地,在吲哚核的7位具有羧酸官能团的90显示出最有效的人β3-AR激动活性。最后,光学分辨率为90导致鉴定出最有前途的化合物,[3-[(2R)-[[(2R)-(3-氯苯基)-2-羟乙基]氨基]丙基]
