描述 LPA (lysophosphatidic acid), which has been shown to be involved in certain diseases such as atherosclerosis and cancer, can act through its receptor like LPA receptor 1, LPA receptor 2, or LPA receptor 3 and elicit different biological actions, like Ca2+ mobilization, changing in cAMP accumulation, changing cell shape and motility, and cell proliferation. Ki16425 is a LPA receptor antagonist with Ki values of 0.34μM for mouse LPA receptor 1 and 0.93μM for human LPA receptor 3, but with much higher Ki value for human LPA receptor 2 (Ki=6.5μM). Pre-treatment with 1μM Ki16425 can inhibit LPA-induced [Ca22+]i increase in THP-1 cells and 3T3 fibroblasts. Also, Ki16425 could decrease the This LPA-induced response of inositol phosphate production in 3T3 fibroblasts and A431 cells, but not S1P3- or S1P2-expressing CHO cells, at concentration of 10μM. The cAMP accumulation inhibited by LPA in FRTL-5 thyroid cells in a PTX-sensitive manner could be almost completely suppressed by 10μM Ki16425. Cell proliferation and migration induced by LPA in Swiss 3T3 fibroblasts could be inhibited dose-dependently by Ki16425. Treatment with Ki16425 at dose of 10mg/kg intradermally could improve dermal and lung fibrosis in a mouse model of bleomycin-induced murine scleroderma. Pre-treatment with 10μM for 30 minutes could completely block LPA-induced YAP/TAZ phosphorylation and inhibit Hippo signaling pathway in HEK293A cells.
作用机制 Ki16425 can antagonize the binding of LPA to the receptor, thus competitively inhibiting LPA-induced GTP binding and LPA receptor binding to membrane fractions.[1]
