Opioid properties of some isomeric derivatives of phencyclidine.
The phencyclidine analogues (+/-)-alpha-, (+/-)-beta-, and (+)-alpha- and and (-)-alpha-4-hydroxy-3-methyl-4-phenyl-1-(1-phenylcyclohexyl)piperidine, all with known relative and absolute stereochemistry, have been prepared, and their analgesic potencies related to corresponding prodines. In contrast to the prodines, the (+/-)-alpha-phencyclidine analogue was a more potent analgesic than its diastereoisomer, while in agreement with observations in the prodine series, the 3R,4S-alpha-enantiomer displayed substantially greater potency than its mirror image form.
