Conivaptan-d4 is intended for use as an internal standard for the quantification of conivaptan (Item No. 23728) by GC- or LC-MS. Conivaptan is an antagonist of the arginine vasopressin (AVP) receptors V1A and V2 (Kis = 0.48 and 3.04 nM for rat liver V1A and kidney V2, respectively).{38430} It also competitively inhibits oxytocin binding to rat uterine oxytocin receptors (Ki = 44 nM) but has no effect on AVP binding to anterior pituitary V1B receptors at concentrations up to 100 μM in a radioligand binding assay. Conivaptan suppresses AVP-induced increases in intracellular calcium in vascular smooth muscle cells (VSMCs) in vitro and the pressor response in pithed rats. Conivaptan (0.01-0.3 mg/kg, i.v.) increases urine output and decreases urine osmolality in dehydrated conscious rats in a dose-dependent manner. It also reduces brain edema and blood-brain barrier disruption in a mouse experimental stroke model.{38431}

    The PtdIn phosphates play an important role in the generation and transduction of intracellular signals.{8344,4096,14518} PtdIns-(3,4,5)-P3-biotin is an affinity probe which allows the PIP3 to be detected through an interaction with the biotin ligand. This design allows PtdIns-(3,4,5)-P3-biotin to serve as a general probe for any protein with a high affinity binding interaction with inositol-(3,4,5)-triphosphate phospholipids, such as phosphatidylinositol 3-kinase, PTEN, or PH-domain-containing proteins.
