Application

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

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.
Ki16452 is a potent antagonist of the lysophosphatidic acid receptors LPA1 and LPA3, with greater than 30-fold selectivity for LPA1 over LPA2. The Ki values for LPA1 and LPA3 are 250 nM and 360 nM, respectively.

Lysophosphatidic acid (LPA) is a multi-function glycerophospholipid. LPA affects the proliferation of hepatocytes and stellate cells in vitro, and in a partial hepatectomy induced liver regeneration model, the circulating LPA levels and LPA receptor (LPAR) expression levels in liver tissue

Tubulointerstitial fibrosis in chronic renal disease is strongly associated with progressive loss of renal function. We studied the potential involvement of lysophosphatidic acid (LPA), a growth factor-like phospholipid, and its receptors LPA(1-4) in the development of tubulointerstitial fibrosis (TIF). Renal

Multiple sclerosis (MS) is a neuroinflammatory disease whose pathogenesis remains unclear. Lysophosphatidic acid (LPA) is an endogenous phospholipid involved in multiple immune cell functions and dysregulated in MS. Its receptor LPA1 is expressed in macrophages and regulates their activation, which

Lipid phosphate phosphatase 3 (LPP3), encoded by the PLPP3 gene, is an integral membrane enzyme that dephosphorylates phosphate esters of glycero- and sphingophospholipids. Cell surface LPP3 can terminate the signaling actions of bioactive lysophosphatidic acid (LPA) and sphingosine 1 phosphate
