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 ^-9M 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 ^-6M to 3 x 10 ^-5M. 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.
