AM966 is a high affinity, selective, oral LPA1-antagonist, inhibits LPA-stimulated intracellular calcium release (IC50=17 nM).
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 Mianserin[2].
AM966 (30 mg/kg, BID) reduces vascular leakage, inflammation and lung injury and inflammation in a 3 day Bleomycin (HY-108345) 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 (HY-B0673) in the 14 day Bleomycin model. AM966 decreases mortality and fibrosis at late time points after Bleomycin injury[1].
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.
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].
