pharmacological results, the functional reversal observed in orvinol analogues by introduction of 7β-methyl substituent could not be reproduced in nepenthone analogues. Alternatively, introduction of 7β-methyl substituent was associated with substantial loss of both subtype selectivity and potency but not efficacy for nepenthone analogues, which was not found in 7β-methyl orvinol analogues.

为了从nepenthone类似物中鉴定出新型的选择性κ阿片受体(KOR)拮抗剂作为潜在的抗抑郁药,从N -nor- N-环丙基甲基-nepenthone(SLL-020ACP)(一种高度选择性和有效的KOR激动剂)开始,一系列的7基于杂交的概念,在阿片样物质受体上构思,合成和测定了β-甲基-nepenthone类似物。根据药理学结果,在戊烯醇类似物中观察到的通过引入7个β-甲基取代基而引起的功能逆转不能在萘哌酮类似物中再现。或者,引入7β-甲基取代基与亚型选择性和效价的实质损失有关,但对萘喷酮类似物却没有效力,这在7个β-甲基或乙烯基醇类似物中没有发现。令人惊讶地,SLL-603,7 β -甲基SLL-020ACP的类似物,被鉴定为一个KOR完全激动剂。还研究了活动悬崖非均质性的可能分子机制。总之,7 β -甲基取代基是具有活性的悬崖相关联,并显示出作为值得进一步调查nepenthone和
