Effects of neurohypophysial hormones and their deamino analogues on renal excretion of Na, K and water in rats.

Endocrinology, 1965
Effects of 8-lysine-vasopressin (LVP), oxytocin and their deamino analogues, l-deamino-8-lysine-vasopressin (deamino- LVP) and 1-deamino-oxytocin, on renal excretion of Na, K and water were studied in anesthetized rats undergoing water diuresis ...

Renal microvascular effects of vasopressin and vasopressin antagonists

American Journal of Physiology-Renal Physiology, 1989
The effects of vasopressin (AVP) and vasopressin antagonists on lumen diameters of cortical afferent and efferent arterioles isolated from rabbit kidneys were examined. Over a concentration range of 10(-14) to 10(-7) M, AVP had no effect on lumen diameters of afferent arterioles, although the arterioles were responsive to norepinephrine.

Solid phase synthesis and some pharmacological properties of 8-D-homolysine-vasopressin and 1-deamino-8-D-homolysine-vasopressin.

International journal of peptide & protein research, 2009
8-DL-Homolysine-vasopressin and its 1-deamino derivative were synthesized by the solid phase method. The desired D-homolysine analogues were obtained by digestion of the mixtures with trypsin and isolation of the peptide components by ion-exchange ...

Vasopressin and Vasopressin Receptor Antagonists in Heart Failure

Cardiology in Review, 2009
Antidiuretic hormone, also known as arginine vasopressin, is a hormone with a multitude of physiologic activities including the control of urinary free water excretion. Antidiuretic hormone also plays a role in vasoconstriction and has 3 receptors that have been identified.

EFFECT OF PITRESSIN ON LIPOLYSIS AND ON PHOSPHORYLASE ACTIVITY IN RAT ADIPOSE TISSUE.

American Journal of Physiology, 1964
Pitressin, a mixture of arginine and lysine vasopressins, stimulates the release of glycerol and of free fatty acids from rat epididymal fat pads in vitro.

Synthèse de La Phe2‐Orn8‐vasopressine et de la Phe2‐oxytocine, deux analogues de la vasopressine doués d'une activité Pressorique sélective

, 1964
Phe2-Orn8-vasopressin and Phe2-Orn8-oxytocin have been prepared by synthesis Both analogues, but especially the second one, have a more selective pressor activity than the natural vasopressins and than most hitherto synthesized analogues these hormones.

Melanophore Stimulating Hormone: Release Inhibition by Ring Structures of Neurohypophysial Hormones

Science, 1972
Tocinamide and tocinoic acid, ring structures of oxytocin, are potent inhibitors of the release of melanophore stimulating hormone from the rat and hamster pituitary in vitro.

Endocrinology of the stress response.

Annual Review of Physiology, 2005
The stress response is subserved by the stress system, which is located both in the central nervous system and the periphery. The principal effectors of the stress system include corticotropin-releasing hormone (CRH); arginine vasopressin; the ...

Oxytocin, Vasopressin, and the Neurogenetics of Sociality

Science, 2008
There is growing evidence that the neuropeptides oxytocin and vasopressin modulate complex social behavior and social cognition. These ancient neuropeptides display a marked conservation in gene structure and expression, yet diversity in the genetic ...
