The effects of a prolylendopeptidase inhibitor, 1−[3−(2−indanylanylacetyl)−L−thioprolyl]pyrrolidine(Z−321), on lordosis behavior were investigated in estrogen and progestrone−treated ovariectomized rats.Females were orally administered 100, 200 or 300 mg/kg Z−321 or the vehicle(control).The mean lordosis quotient in the rats given 300 mg/kg Z−321 was lower than that in control group, but that in rats given 100 or 200 mg/kg Z−321 was not lower.Thus, Z−321 suppressed lordosis in estrogen and progesterone−treated ovariectomized rats.Peptide neurotransmitters, especially those containing proline, are though to be involved in the inhibitory mechanisms for lordosis behavior.
