function was also found to influence the specificity of the compounds. Shift of the hydroxy group from the 2'-position to the 3'-position significantly increased the affinity for the NMDA receptor-channel complex and considerably reduced the affinity for the mu opioid receptor. From this series of 6,7-benzomorphan derivatives, the compound 15cr.HCl [(2R)-[2 alpha, 3(R*),6 alpha]-1,2,3,4,5,6-hexahydro-3-(2-methoxypropyl)-6
我们已经合成了一系列具有修饰的N-取代基的立体异构体6,7-苯并吗啡衍生物,并确定了它们在体外和体内拮抗N-甲基-D-天冬氨酸(NMDA)受体通道复合物的能力。将化合物从大鼠脑突触体膜中的NMDA受体的通道位点置换[3H] -MK-801的能力和抑制NMDA诱导的小鼠致死性的能力与它们与μ阿片受体结合的能力进行了比较。结构-活性关系的研究表明,绝对立体化学对于区分这两种作用至关重要。(-)-1R,9 beta,2“ S-对映异构体对NMDA受体通道复合物的亲和力高于对μ阿片受体的亲和力。还发现芳香族羟基官能团会影响化合物的特异性。羟基从2'-位置向3'-位置的转移显着增加了对NMDA受体-通道复合物的亲和力,并显着降低了对μ阿片样物质受体的亲和力。从这一系列的6,7-苯并吗啉衍生物中,化合物15cr.HCl [(2R)-[2 alpha,3(R *),6 alpha] -1,2,3,4,5
