A class of new 4-amino-4-arylcyclohexanones, their ketals, and acid addition salts have been synthesized and found to be useful for relieving pain in animals. Their analgesic activity appears to be of high order, and in addition some exhibit narcotic antagonist activity that is useful in modifying the cardiovascular, respiratory, and behavioral depression caused by other analgesics. Several show mixed analgesic and narcotic antagonist activity. Preferred compounds of the class are 4-(m-hydroxyphenyl)-4-dimethylaminocyclohexanone ethylene ketal, and 4-(m-hydroxyphenyl)-4-(n-butylmethylamino)cyclohexanone ethylene ketal as free bases and as their hydrochloride salts. Processes for synthesis and intermediates are described. Unit dosage forms and therapeutic treatments are disclosed.
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。
