Inhibition of Luteinizing Hormone Release by Analogs of Luteinizing Hormone-Releasing Hormone (LHRH)in Vitro

Abstract

Sixteen synthetic analogs of LH-releasing hormone (LHRH) were tested for their ability to inhibit the stimulation of LH release induced by 3 X 10(-9)M LHRH in anterior pituitary cells in monolayer culture. Half-maximal inhibition of LHRH-induced LH release was obtained with 7 analogs at concentrations which ranged from 3 X 10(-6)M to 3 X 10(-5)M. None of these seven analogs had significant LH-releasing activity at concentrations up to 10-5M. Nine analogs had no detectable antagonistic activity when tested in up to a 3000-fold molar ratio of analog to LHRH.
