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 snythesis 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、它们的缩酮和酸加成盐已被合成并发现对缓解动物疼痛有用。它们的镇痛活性似乎是高级别的,另外一些表现出麻醉拮抗活性,有助于改变其他镇痛剂引起的心血管、呼吸和行为抑制。几种显示出混合的镇痛和麻醉拮抗活性。该类化合物的首选物是4-(间羟基苯基)-4-二甲氨基环己酮乙二醇缩酮和4-(间羟基苯基)-4-(正丁基甲基氨基)环己酮乙二醇缩酮,作为自由碱和它们的盐酸盐。描述了合成和中间体的过程。揭示了单元剂量形式和治疗方法。
