Optically pure (R)- and (S)-N-alkyl-1-cyclohexyl-2-phenylethylamine hydrochlorides (9a-r)were synthesized from (R)- and (S)-phenylglycine by means of a simple procedure. The analgesic activity of these compounds was evaluated by the acetic acid writhing method, and 9e, 9f, 9i-k, and 9m showed more potent activity than (-)-pentazocine hydrochloride. Moreover, the analgesic activities of 9a-e, 9h, 9i, 9m, and 9o-r were not antagonized by naloxone.
通过简单的程序从(R)-和(S)-苯甘氨酸合成了光学纯度为(R)-和(S)-N-烷基-1-环己基-2-苯乙胺盐酸盐(9a-r)。这些化合物的镇痛活性通过醋酸蠕动法进行了评估,9e、9f、9i-k 和 9m 比 (-)-pentazocine 盐酸盐表现出更强的活性。此外,纳洛酮不会拮抗 9a-e、9h、9i、9m 和 9o-r 的镇痛活性。
