title: Desensitization of renal vasopressin-stimulated adenylate cyclase by a vasopressor and antidiuretic antagonist, [1-(beta-mercapto-beta,beta-cyclopentamethylenepropionic acid),2-(O-ethyl)-D-tyrosine, 4-valine]arginine vasopressin.
abstract: Desensitization of the renal antidiuretic (V2) receptor has been regarded as agonist-specific. We found that a vasopressor and antidiuretic (V1V2) antagonist d(CH2)5DTyr(Et)VAVP induced desensitization of the receptor and that a vasopressor (V1) antagonist d(CH2)5Tyr(Me)AVP, which is a weak antidiuretic (V2) agonist, counteracted the potent desensitizing action of 1-deamino-8-D-arginine-vasopressin and endogenous arginine vasopressin.
