1 [1-Deaminocysteine,2-phenylalanine,7-(3,4-didehydroproline),8-arginine] vasopressin, a vasopressin analogue with enhanced antidiuretic potency, is relatively ineffective at stimulating phosphatidylinositol metabolism. Phosphatidylinositols arginine vasopressin Rattus norvegicus
2 This suggests that the hepatic vasopressin receptors that stimulate phosphatidylinositol breakdown are different in their ligand selectivity from the antidiuretic vasopressin receptors that activate renal adenylate cyclase. Phosphatidylinositols arginine vasopressin Rattus norvegicus
3 These results may be an indication that phosphatidylinositol breakdown is an integral reaction in the stimulus-response coupling sequence(s) that link(s) activation of alpha-adrenergic, vasopressin and angiotensin receptors to mobilization of Ca(2+) in the rat hepatocyte. Phosphatidylinositols arginine vasopressin Rattus norvegicus
