VPC 23019

The Uses of VPC 23019

VPC 23019 is a sphinosine-1 phosphate antagonist.

What are the applications of Application

VPC 23019 is an antagonist of the EDG(sphingosine-1-phosphate receptor)

Definition

ChEBI: VPC 23019 is a secondary carboxamide resulting from the formal condensation of the carboxy group of O-phospho-D-serine with the amino group of m-octylaniline. An analogue of sphingosine-1-phosphate (S1P), it is a potent antagonist for both S1P1 and S1P3 receptors. It can inhibit S1P-induced migration of thyroid cancer cells, ovarian cancer cells, and neural stem cells. It has a role as a sphingosine-1-phosphate receptor 3 antagonist and a sphingosine-1-phosphate receptor 1 antagonist. It is a D-serine derivative, a secondary carboxamide, an organic phosphate, a phosphoric ester and an aromatic amide. It is functionally related to an O-phospho-D-serine.

Biological Activity

vpc 23019, phosphoric acid mono-[2-amino-2-(3-octyl-phenylcarbamoyl)-ethyl] ester, is an s1p1/s1p3 receptor antagonist. s1p is short for sphingosine-1-phosphate [1]. vpc 23019 abolished s1p-induced, cell migration, gi-dependent rac stimulation and tube formation [2]. vpc 23019 inhibited sip1 activity with an ic50 value of 8 nm [3].s1p can act on specific g protein-coupled receptors. 5 subtypes of these receptors have been found and termed s1p1–5. these receptors couple to intracellular second messenger systems including intracellular ca2+, phospholipase c, adenylyl cyclase, phosphatidylinositol 3 (pi3)-kinase, mitogen-activated protein kinases, protein kinase akt, and ras- and rho-dependent pathways [1].in the bend.3 cell line, vpc 23019 did not affect basal no production. preincubation with 10 μmol/l vpc 23019 made ang ii–induced no production decrease to approximately basal level [1]. s1p, in a dose-dependent manner, stimulated trans-well migration of mouse vascular endothelial cells with a peak response at 10-7m. vpc 23019 was able to abolish this stimulatory effect of s1p [2]. preincubation with 10 μm of vpc 23019 partially inhibited s1p-induced calcium increase in l2071 cells [4].in rat, vpc 23019 significantly increased the s1p-induced vasoconstriction in preparation with intact endothelium (p< 0.01), but did not change it in preparation without endothelium. in intact mouse basilar artery (relaxation to ach, 45.6±7.2%, n= 16), vpc 23019 left-shifted the concentration-contraction curve to s1p by a half log. vpc 23019 did not modify contractile responses to 5-ht, kcl or u46619 [5].
