Mechanism of Action

Targets/IC₅₀/Ki	TGFβRI (Cell-free assay) 59 nM RIPK2 (Cell-free assay) 0.11 μM CK1δ (Cell-free assay) 0.22 μM TGFβRII (Cell-free assay) 0.4 μM MLK-7K (Cell-free assay) 1.4 μM
In vitro	LY364947 is an ATP competitive and tight-binding inhibitor, inhibiting phosphorylation of P-Smad3 by TGFβR-I kinase with Ki of 28 nM. This compound inhibits in vivo Smad2 phosphorylation within the NMuMg cells with IC50 of 135 nM. It reverses TGF-β-mediated growth inhibition in NMuMg cells with IC50 of 0.218 μM. This chemical potentiates the xVent2-lux BMP4 response in NMuMg cells by 30% at concentrations as low as 0.25 μM. It (2 μM) prevents TGF-β-induced epithelial−mesenchymal transition in NMuMg cells. This compound (3 μM) induces expression of Prox1 and LYVE-1 in almost all HDLECs after 24 hours. It promotes nuclear export of Foxo3a, with low Smad2/3 and high Akt phosphorylation levels in leukaemia-initiating cells. This chemical (< 20 μM) suppresses leukaemia-initiating cells colony-forming ability after co-culture with OP-9 stromal cells.
Kinase Assay	Filter-binding assay
Kinase Assay	The IC50 of LY364947 at different enzyme concentrations are determined by the filter-binding assay. Typically, 40 μL reactions in 50 mM HEPES at pH 7.5, 1 mM NaF, 200 μM pKSmad3(−3), and 50 mM ATP containing a titration of each inhibitor with concentrations of 1600, 800, 400, 200, 100, 50, 25, and 0 nM are incubated at 30 °C for 30 min. The IC50 is calculated using a nonlinear regression method with GraphPad Prism software. The binding type is determined by plotting the correlation between enzyme concentrations and IC50 values.
In vivo	LY364947 (1 mg/kg i.p.) accelerates lymphangiogenesis, as evidence by significantly increased the LYVE-1-positive areas, in a mouse model of chronic peritonitis. This compound significantly increases the LYVE-1-positive areas in tumor tissues in tumor xenograft models using BxPC3 pancreatic adenocarcinoma cells. This chemical increases p-Akt and decreases nuclear Foxo3a in leukaemia-initiating cells in CML-affected mice.
