Conivaptan
Based on 14 publication(s) in Google Scholar
Conivaptan (YM 087 free base) is an orally active dual vasopressin V1a/V2 receptor antagonist with Ki values of 0.48 nM and 3.04 nM for vasopressin V1a receptor and V2 receptor, respectively. Conivaptan competitively and reversibly blocks vasopressin-mediated antidiuresis, vasoconstriction, and cellular hypertrophy, while inhibiting CYP3A4. Conivaptan inhibits vasopressin-induced intracellular calcium, cAMP, and mitogen-activated kinase activation in vascular smooth muscle cells and cardiomyocytes. Conivaptan induces water diuresis while improving hemodynamics in heart failure models, reducing left ventricular end-diastolic pressure, vascular resistance, and organ weight. Conivaptan is used for research on hyponatremia and congestive heart failure.

In Vitro
Conivaptan binds to vasopressin V1a receptors (Ki = 0.48 nM) and vasopressin V2 receptors (Ki = 3.04 nM) in a competitive and reversible manner, and shows almost no activity against vasopressin V1b receptors[1].
Conivaptan inhibits vasopressin-triggered intracellular calcium elevation in vascular smooth muscle cells (IC50 = 1.16 nM) and simultaneously inhibits vasopressin-induced cAMP accumulation (IC50 = 17.3 nM)[1].
Conivaptan binds with high affinity to canine platelet V1a receptors (Ki = 0.6 nM) and canine kidney V2 receptors (Ki = 0.7 nM), binds to rhesus monkey liver V1a receptors (Ki = 26 nM) and rhesus monkey kidney V2 receptors (Ki = 10 nM), and inhibits AVP binding to human cloned V1a receptors (Ki = 6.3 nM) and V2 receptors (Ki = 1.1 nM) in COS1 cells.
Conivaptan inhibits AVP-induced increases in Ca2+ and cAMP in COS1 cells expressing human receptors, with IC50 values of 2.0-14.3 nM; it inhibits AVP-induced Ca2+, mitogen-activated kinase, and protein synthesis in rat cardiomyocytes expressing V1a receptors; and it inhibits AVP-induced proliferation and hypertrophy of vascular smooth muscle cells in growth-arrested rats[1].

Saturation experiments for Conivaptan hydrochloride-red (0.1-100 nM, final concentration) binding to the SNAP-tagged HEK293hV2R cells at 25 ℃ and 37 ℃; total binding, non-specific binding and specific binding are shown. Nonspecific binding was determined in the presence of 100 μM Conivaptan hydrochloride and represented less than 10% of the total Conivaptan hydrochloride-red binding. Data are from three independent experiments each performed in duplicate.
