N-Aliphatic ester analogues of the non-opioid ketamine (1) retain effective anaesthetic/analgesic properties while minimising ketamine's psychomimetic side-effects. We show that the anaesthetic/analgesic properties of these ester analogues depend critically on the length (from 2 to 4 carbons), polarity and steric cross-section of the aliphatic linker chain. More stable amide and ethylsulfone analogues generally
非阿片类氯胺酮的N-脂族酯类似物(1)保留了有效的麻醉/镇痛特性,同时最大程度地降低了氯胺酮的拟精神病副作用。我们表明,这些酯类似物的麻醉/镇痛特性主要取决于脂肪族连接链的长度(2至4个碳),极性和空间截面。较稳定的酰胺和乙砜类似物通常显示较弱的麻醉/镇痛活性。化合物的麻醉/镇痛特性与其对N-甲基-d-天冬氨酸(NMDA)受体的结合亲和力之间没有相关性。
