3-(Cyclopropylmethyl)-9-hydroxy-7-oxo-2,3,4,4a alpha,5,6,7,7a alpha- octahydro-1H-benzofuro[3,2-e]isoquinoline (4b) containing the ACNO ring system of morphine and a 7-keto function on ring C has been synthesized and found to possess potent PQW (ED50 = 0.15 mg/kg sc) and anti-Straub tail (ED50 = 0.02 mg/kg sc) activity. As compared to its 7-deoxy analog 1b, introduction of the 7-keto group did not
3-(环丙基甲基)-9-羟基-7-氧代-2,3,4,4aα,5,6,7,7aα-八氢-1H-苯并呋喃[3,2-e]异喹啉(4b)已合成吗啡的ACNO环系统和在C环上具有7-酮功能,并发现其具有有效的PQW(ED50 = 0.15 mg / kg sc)和抗Stratraub尾巴(ED50 = 0.02 mg / kg sc)活性。与7-脱氧类似物1b相比,引入7-酮基不会显着影响与三种阿片受体(mu,kappa和delta)的结合,但会导致sigma结合降低34倍,提示降低拟精神药作用的倾向。4b(4c)的C / D顺式异构体在三个阿片受体上的效价要低得多,而sigma亲和力则略有增加。7-羟基衍生物4e和4f在抗Straight尾巴测定中均具有活性(ED50 <或= 0.8 mg / kg sc),但只有α-异构体4e在所测试的剂量范围内显示出镇痛活性(PQW ED50 = 0.37 mg
