Abstract

Dose-response studies with des-(pyro) Glu-LH-RH, [Phe³] LH-RH, [Phe⁵] LH-RH [0-methyl-Tyr⁵] LH-RH, [Ile⁷] LH-RH and des-Gly¹⁰-LH-RH-ethylamide show concomitant stimulation of adenohypophyseal adenosine 3',5'-monophosphate (cyclic AMP) concentration, and LH and FSH release in rat anterior pituitary gland in vitro. Des-His²-des-Gly¹⁰-LH-RH-ethylamide, and inhibitor of the response to LH-RH in vivo, had no effect on cyclic AMP accumulation or on LH release in vitro. The present finding of parallel changes of intracellular cyclic AMP levels and hormonal release with LH-RH analogs having a wide spectrum of biological activity adds strong support for a role of the cyclic nucleotide as mediator of the action of LH-RH in the anterior pituitary gland.
