Pharmacology of CP-99,994; a nonpeptide antagonist of the tachykinin neurokinin-1 receptor.

(+)-(2S,3S)-3-(2-methoxybenzylamino)-2-phenylpiperidine (CP-99,994) binds selectively and with high affinity (Ki = 0.25 nM) to neurokinin (NK)-1 tachykinin receptors in a human cell line and in guinea pigs where it acts as an antagonist as evidenced by its blockade of substance P-induced excitation of locus coeruleus neurons in vitro. Subcutaneously administered CP-99,994 antagonized locomotor activity in guinea pigs induced by intraventricular infusion of [Sar9,Met(O2)11]-substance P (50 micrograms) with an ID50 = 0.59 mg/kg, indicating that CP-99,994 penetrates into the central nervous system. Orally administered CP-99,994 potently blocked (ID50 = 4 mg/kg) the leakage of Evans blue dye into trachea and bronchi elicited by exposure of guinea pigs to aerosol capsaicin (1 mM). CP-99,994 has reduced affinity (IC50 = 3 microM) for the L-type calcium channel in contrast to CP-96,345 (IC50 = 27 nM) an earlier nonpeptide antagonist. Thus, CP-99,994 represents an important pharmacological tool for investigating the physiological role of substance P and a potentially novel therapeutic agent for treating a variety of diseases.[1]
