    Concentration-dependent effects of LPA receptor antagonists on antidepressant- and LPA-induced ERK1/2 phosphorylation in C6 glioma cells. Cells are pre-incubated with either vehicle or the indicated concentrations of AM966 for 10 min and then exposed to either vehicle or 1 μM LPA (A), 15 μM Amitriptyline (C) or 5 μM Mianserin (E) for 10 min.

    CHO-K1 cells express LPA1 receptors coupled to ERK1/2 phosphorylation. Inhibition of LPA-induced phospho-ERK1/2 by AM966. Cells are pre-incubated with either vehicle or the indicated concentrations of AM966 for 30 min and then treated with LPA (300 nM) for 15 min. Values are expressed as percent of p-ERK stimulation elicited by LPA in the absence of antagonist and are the mean ± SEM of three experiments.

    Effects of LPAR antagonists on growth factor-induced phosphorylation of ERK in DU145 cells. Serum starved DU145 cells are incubated with 10 μM LPA, with or without either 100 nM AM966 or 10 μM Ki16425 for 10 minutes. Whole-cell extracts, equalized for protein, are immunoblotted for phospho-ERK (pERK) and for actin (loading control).

    IC50 & Target


    In Vitro

    AM966 is a potent, selective, orally bioavailable LPA1 receptor antagonist. AM966 inhibits LPA1-mediated chemotaxis of human A2058 melanoma cells (IC50=138±43 nM), IMR-90 human lung fibroblasts (IC50=182±86 nM) and CHO mLPA1 cells (IC50=469±54 nM)[1]. LPA-induced ERK1/2 activation is completely blocked by AM966 (100 nM), which selectively antagonizes LPA1 over LPA2-5, with an IC50 value of 3.8±0.4 nM. Pre-treatment with AM966 (100 nM) completely blocks ERK1/2 phosphorylation induced by either amitriptyline or mianserin[2].

    In Vivo

    AM966 (30 mg/kg, BID) reduces vascular leakage, inflammation and lung injury and inflammation in a 3 day bleomycin model. AM966 inhibits lung fibrosis, maintains mouse body weight and decreases lung inflammation 14 days after bleomycin lung injury. AM966 reduces vascular leakage, tissue injury and pro-fibrotic cytokine production in the 14 day bleomycin study. AM966 demonstrates greater efficacy compared to pirfenidone in the 14 day bleomycin model. AM966 decreases mortality and fibrosis at late time points after bleomycin injury[1].

    Cell Assay

    AM966 (Chem Scene, Monmouth Junction, NJ, USA) is dissolved in DMSO and stored, and then diluted with appropriate media (DMSO 0.5%) before use[2].

    CHO-K1 cells are grown to 80% confluency in 12-well plates, serum-starved for 24 h and incubated in serum-free medium with AM966. After 21 h, [3H]thymidine (0.5 μCi/well) is added and the incubation is continued for 3 h. The medium is then removed, and the cells are placed on ice and washed twice with 1 mL of ice-cold PBS containing 5% trichloroacetic acid. Cells are solubilized and [3H]thymidine incorporation is determined by liquid scintillation counting. Assays are performed in triplicate[2]. MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration

    AM966 is prepared in water (Mice)[1].

    The oral exposure of AM966 is determined in fasted mice. Animals received AM966 (10 mg/kg) in vehicle (water) by oral gavage and are then killed by CO2 inhalation at 1, 2, 4, 8 and 24 h post dose (n=2 animals per time point for each test compound). Blood (approximately 300 µL) is collected via cardiac puncture into EDTA-containing tubes and centrifuged at 1450×g for 10 min. The plasma is removed and analysed for AM966 content by liquid chromatography-mass spectrometry (LCMS). Briefly, known amounts of AM966 are added to thawed mouse plasma to yield a concentration range from 0.8 to 4000 ng/mL. Mouse plasma samples are precipitated using acetonitrile (1:4, v:v) containing the internal standard buspirone. A 10 µL aliquot of the analyte mixture is injected using a Leap PAL autosampler. Analyses are performed using an Agilent Zorbax SB-C8 column (2.1×50 mm; 5 µm) linked to a Shimadzu LC-10AD VP with SCL-10A VP system controller. Tandem mass spectrometric detection is carried out on a PE Sciex API3200 in the positive ion mode (ESI) by multiple reaction monitoring. The calibration curves are constructed by plotting the peak-area ratio of analysed peaks against known concentrations. The lower limit of quantitation is 0.8 ng/mL. The data are subjected to linear regression analysis with 1/x2weighting. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
