Biological Activity

Description	Desmopressin is a synthetic octapeptide, and an analogue of human hormone arginine vasopressin with antidiuretic and coagulant activities. It is a selective agonist for the vasopressin V2 receptor (V2R).

In vitro
In vitro	Desmopressin (DDAVP) is a selective agonist for the vasopressin V2 receptor (V2R), which is coupled to cAMP-dependent signaling. DDAVP induces cAMP-dependent eNOS activation via Ser1177 phosphorylation. DDAVP (at doses ranging from 100 ng/ml to 1 μg/ml) exerts a modest but significant antiproliferative effect on cultured CT-26 and Colo-205 cells.
Cell Research	Cell lines	HUVECs
	Concentrations	1 μM
	Incubation Time	25 min
	Method	HUVECs are transduced with recombinant adenoviruses AdV2R.EGFP (AdV2R) or AdlacZ. 3 days later cells are incubated for 25 min with 1 μM DDAVP or 10 μM forskolin, both in presence of IBMX. Cell extracts are analyzed for eNOS Ser1177 phosphorylation and eNOS expression.

In Vivo
In vivo	In vivo, DDAVP (2 μg/kg) reduces accumulation of ascites and formation of intestinal tumor nodules in mice intraperitoneally inoculated with CT-26 cells. Perioperative administration of DDAVP significantly inhibits tumor progression in animals surgically implanted in the spleen with CT-26 cells, and causes some reduction in liver metastasis. DDAVP is able to inhibit lung colonization by blood-borne breast cancer cells in an experimental murine model. It dramatically reduces lymph node and lung metastasis in a model of mammary tumor manipulation and surgical excision in mice when administered perioperatively, and also exerts antitumor effects in combination with chemotherapy. DDAVP increases the plasma levels of coagulation factor VIII, von Willebrand factor (VWF) and tissue-type plasminogen activator, and also enhances platelet adhesion to the vessel wall.
