KI16425

Description

Lysophosphatidic acid (LPA) is a bioactive lipid mediator that signals through five distinct G protein-coupled receptors (LPA_1-5). Ki16425 is a LPA receptor antagonist with selectivity for LPA₁ and LPA₃. It exhibits K_i values of 0.34, 6.5, and 0.93 μM for the human LPA₁, LPA₂, and LPA₃ receptors, respectively, as determined by measuring inositol phosphate production in RH7777-transfected cells. Ki1642, at 10 μM, significantly blocks the response of a variety of cancer cell lines to LPA-induced cell migration.

The Uses of KI16425

Ki16425 is a competitive, potent and reversible antagonist to LPA1, LPA2 and LPA3.

The Uses of KI16425

Ki 16425 has been used as a chemical inhibitor to study the regulation of LPA (lysophosphatidic acid) on LPAR(LPA receptor) subtypes.

What are the applications of Application

Ki16425 is a competitive inhibitor of EDG-2, EDG-4, and EDG-7

Definition

ChEBI: 3-[({4-[4-({[1-(2-chlorophenyl)ethoxy]carbonyl}amino)-3-methyl-1,2-oxazol-5-yl]phenyl}methyl)sulfanyl]propanoic acid is a member of the class of isoxazoles that is the carbamate ester obtained by formal condensation of the carboxy group of 1-(2-chlorophenyl)ethyl hydrogen carbonate with the amino group of 3-({[4-(4-amino-3-methyl-1,2-oxazol-5-yl)phenyl]methyl}sulfanyl)propanoic acid. It is a member of isoxazoles, a carbamate ester, a member of monochlorobenzenes, an organic sulfide and a monocarboxylic acid.

Biochem/physiol Actions

Ki 16425 possesses a short-lived inhibitory activity. It has been studied that Ki 16425 is effective in the inhibition of neuropathic pain‐like behaviors.
