CP-96,345 ((2S, 3S)-cis-2-(diphenylmethyl)-N-((2-methoxyphenyl)methyl)-1-azabicyclo(2.2.2)octan-3-amine) antagonism of substance P-stimulated salivation was investigated in pentobarbital-anesthetized rats. Administered either intraperitoneally or orally, CP-96,345 produced dose-dependent inhibition of the sialogogic response elicited by substance P but had no effect on acetylcholine-stimulated salivation. CP-96,345 produced concentration-dependent inhibition of ({sup 3}H)substance P binding to rat submaxillary gland membranes, with a median effective concentration of 34{plus minus}3.6 nM. These biological activities were confined to CP-96,345 in that the 2R, 3R enantiomer (CP-96,344) was without effect.
