aliphatic esters of the non-opioid anaesthetic/analgesic ketamine were prepared and their properties as shorter-acting analogues of ketamine itself were explored in an infused rat model, measuring the time after infusion to recover from both the anaesthetic (righting reflex) and analgesic (response to stimulus) effects. The potency of the esters as sedatives was not significantly related to chain length
制备了一系列非阿片类麻醉剂/镇痛剂氯胺酮的脂族酯,并在输注的大鼠模型中探索了其作为氯胺酮本身的短效类似物的性质,测量了输注后从两种麻醉剂中恢复的时间(对位反射)和镇痛作用(对刺激的反应)。酯类作为镇静剂的效力与链长没有显着关系,但是Me,Et和i-Pr酯的剂量效价更高(最多比氯胺酮低两倍),而n-Pr酯的效价更低(从2-比氯胺酮少6倍)。对于Me,Et和i-Pr酯,麻醉后的回收率比氯胺酮本身快10–15倍;对于n-Pr酯,麻醉剂的回收率比氯胺酮快20–25倍。
