  名称：

  4-Amino-4-arylcyclohexanones and their derivatives, a novel class of analgesics. 1. Modification of the aryl ring

  摘要：

  Investigation of central nervous system activity of phenylcyclohexylamines was continued by preparation of "reversed" analogues. Following the unexpected finding of analgesic activity with 1-(dimethylamino)-1-phenylcyclohexylamine, the SAR of the series was investigated. Synthesis starts by double Michael reaction of acrylate on arylacetonitriles. Following cyclization, decarboxylation, ketalization, and saponification, the geminally substituted acid is rearranged to the isocyanate by means of (C6H5O)2PON3. Isocyanates were then converted to the title compounds. Analgesic activity is very sensitive to the nature and position of the substitutent on the aromatic ring. The most potent compounds in this series (p-CH3, p-Br) showed 50% the potency of morphine. Deletion of the ring oxygen abolishes activity.

  摘要：

  一类新的4-氨基-4-芳基环己酮，它们的缩醛和酸盐已经合成，并发现对于缓解动物的疼痛很有用。它们的镇痛活性似乎是很高的，并且一些还表现出对镇痛引起的心血管、呼吸和行为抑制有用的麻醉拮抗活性。其中几种显示出混合的镇痛和麻醉拮抗活性。该类化合物的首选化合物是4-(间羟基苯基)-4-二甲氨基环己酮乙二醚缩醛，以及4-(间羟基苯基)-4-(正丁基甲基氨基)环己酮乙二醚缩醛，作为游离碱和其盐酸盐形式。描述了合成和中间体的过程。披露了单位剂量形式和治疗方法。
