Bioactivity | Ki16425 (Debio 0719) is a subtype-selective, competitive antagonist of the EDG-family receptors, LPA1 and LPA3 with Kis of 0.34 μM and 0.93 μM, respectively. Ki16425 (Debio 0719) reduces the LPA-induced activation of p42/p44 MAPK[1][2]. Ki16425 can also inhibit LPA-induced dephosphorylation of Yes-associated protein (YAP)/TAZ in HEK293A cells[3]. | ||||||||||||
Target | Ki: 0.34 μM (LPA1), 0.93 μM (LPA3), 6.5 μM (LPA2) | ||||||||||||
Invitro | Ki16425 (10 μM; 1.5 hours; HEK293A cells) treatment blocks LPA-induced dephosphorylation of YAP/TAZ in HEK293A cells. Ki16425 partially inhibits the ability of serum to repress YAP/TAZ phosphorylation, particularly at low serum concentrations (0.2%)[3]. Western Blot Analysis[3] Cell Line: | ||||||||||||
In Vivo | Ki16425 (Debio 0719) (1-30 mg/kg; i.p.; at 30 min prior to LPA injection) inhibits LPA-induced neuropathic pain-like behaviors[4]. Animal Model: | ||||||||||||
