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[1]. 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[2].
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[2]. 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[1].
