    LY-364947 (HTS466284) is a potent ATP-competitive inhibitor of TGFβR-I with IC50 of 59 nM, and exhibits 7-fold selectivity over TGFβR-II[1].

    IC50 & Target

    IC50: 59 nM (TGFβR-I)

    In Vitro

    LY-364947 is an ATP competitive and tight-binding inhibitor, inhibiting phosphorylation of P-Smad3 by TGFβR-I Kinase with Ki of 28 nM. LY-364947 inhibits in vivo Smad2 phosphorylation within the NMuMg cells with IC50 of 135 nM. LY-364947 reverses TGF-β-mediated growth inhibition in NMuMg cells with IC50 of 0.218 μM. LY-364947 potentiates the xVent2-lux BMP4 response in NMuMg cells by 30% at concentrations as low as 0.25 μM. LY-364947 (2 μM) prevents TGF-β-induced epithelial−mesenchymal transition in NMuMg cells[1]. LY-364947 (3 μM) induces expression of Prox1 and LYVE-1 in almost all HDLECs after 24 hours[2]. LY-364947 promotes nuclear export of Foxo3a, with low Smad2/3 and high Akt phosphorylation levels in leukaemia-initiating cells. LY-364947 (< 20 μM) suppresses leukaemia-initiating cells colony-forming ability after co-culture with OP-9 stromal cells[3].

    In Vivo

    LY-364947 (1 mg/kg, i.p.) accelerates lymphangiogenesis, as evidence by significantly increasing the LYVE-1-positive areas in a mouse model of chronic peritonitis. LY-364947 (1 mg/kg, i.p.) significantly increases the LYVE-1-positive areas in tumor tissues in tumor xenograft models using BxPC3 pancreatic adenocarcinoma cells[2]. LY-364947 (25 mg/kg) increases p-Akt and decreases nuclear Foxo3a in leukaemia-initiating cells in CML-affected mice[3].

    Animal Administration

    BALB/c nude mice 5 to 6 weeks of age are used in the assay. Parental, or VEGF-C- or TGF-β1-expressing tumor cells (5×106) in 100 μL PBS are implanted subcutaneously into male nude mice and allowed to grow for 2 to 3 weeks to reach proliferative phase, before initiation of TβR-I inhibitor administration. TβR-I inhibitor LY-364947, dissolved in 5 mg/mL in DMSO and diluted with 100 μL PBS, or the vehicle control, is injected intraperitoneally at 1 mg/kg, 3 times a week for 3 weeks. Excised samples are directly frozen in dry-iced acetone for immunohistochemistry. Frozen samples are further sectioned at 10-μm thickness in a cryostat and subsequently incubated with primary and secondary antibodies. Samples are observed using a confocal microscope.
