(±)-Trans-Ph/Et and (±)-cis-Ph/Et 1-(2-ethyl-1-phenylcyclohexyl)piperidine were synthesized from 2-ethylcyclohexanone. In contrast to the corresponding trans-substituted 2-methyl compound which is 5x more potent than PCP, the trans-2-ethyl derivative has a 75x lower affinity for the PCP binding site. The cis-2-ethyl isomer is inactive like the cis-2-methyl derivative. (±)-1-(1- Phenylcyclohexyl)-2-methylpiperidine is almost as active as the parent PCP. Reduction of the aromatic ring or quaternization of the piperidine in PCP reduces the affinity for the PCP site.
(±)-Trans-Ph/Et 和 (±)-cis-Ph/Et 1-(2-乙基-1-苯基环己基)哌啶是从2-乙基环己酮合成的。与相应的trans-取代的2-甲基化合物相比,其效力是PCP的5倍,而trans-2-乙基衍生物对PCP结合位点的亲和力降低了75倍。cis-2-乙基异构体与cis-2-甲基衍生物一样不活跃。(±)-1-(1-苯基环己基)-2-甲基哌啶的活性几乎与母体PCP相当。对PCP中的芳环进行还原或对哌啶进行季铵化会降低其对PCP位点的亲和力。
