製品説明

Ki16425 is a competitive, potent and reversible antagonist to LPA1, LPA2 and LPA3 with K_i of 0.34 μM, 6.5 μM and 0.93 μM in RH7777 cell lines, respectively, shows no activity at LPA4, LPA5, LPA6.

Targets

LPA1 ^[1] (RH7777 cells)	LPA3 ^[1] (RH7777 cells)	LPA2 ^[1] (RH7777 cells)
0.34 μM(Ki)	0.93 μM(Ki)	6.5 μM(Ki)

In Vitro
In vitro	Kil6425 preferentially inhibits LPA1- and LPA3-mediated responses but has only a moderate effect on LPA2. Ki16425 inhibits the LPA-induced Ca(2+) response in THP-1 cells, 3T3 fibroblasts, and A431 cells, but had only a marginal effect in PC-12 cells and HL-60 cells, which means that Ki16425 seems to be a useful tool for evaluating the involvement of specific LPA receptors in the short-term response to LPA. Ki16425 inhibits long-term DNA synthesis and cell migration as induced by LPA in Swiss 3T3 fibroblasts. ^[1] Ki16425 reduces the LPA-induced activation of p42/p44 mitogen activated protein kinase (MAPK), while acting as a weak stimulator of p42/p44 MAPK on its own, properties typical of a protean agonist. Ki16425 also significantly reduces the NGF-induced stimulation of p42/p44 MAPK and inhibited NGF-stimulated neurite outgrowth in PC-12 cells. ^[2] Ki16425 markedly inhibits the expressions of COX-2 protein induced by synovial fluids. The enhancement of the IL-1 action by LPA on COX-2 expression is also inhibited by Ki16425. ^[3]

In Vivo
In Vivo	Ki-16425 (30 mg/kg, i.p.) completely blocks LPA-induced neuropathic pain-like behaviors, when administered 30 min but not 90 min before lysophosphatidic acid injection, suggesting that Ki-16425 is a short-lived inhibitor. Ki-16425 also inhibits nerve injury-induced up-regulation of Caα2δ-1 in the dorsal root ganglion and reduction of SP immunoreactivity in the spinal dorsal horn. ^[4]
動物実験	動物モデル	Male standard ddY-strain mice are used.
	投与量	30 mg/kg.
	投与経路	Administered via i.p.
