General Description

A cell permeable imidazopyridine-carboxylate derived compound that acts as a potent and selective inhibitor of phosphatidylinositol 3-kinase a (PI3Ka; IC₅₀= 800 pM). Blocks the proliferation of several cancer cells (IC₅₀= 600 nM; 1.5 µM, and 7.8 µM for T47D, SK-BR3, and MCF-7 cells, respectively). Suppresses the growth and proliferation of hepatic stellate cells (HSC-T6 and LX-2 cells) and induces cell cycle arrest at G2/M phase in a dose and time-dependent manner. Induces apoptosis in HSC-T6 cells (~5 µM) as evidenced by morphological changes, activation of caspase-3, reduction in Bcl-2 levels, and loss of mitochondrial transmembrane potential. Exhibits anti-fibrolytic activity and diminishes the expression of profibrotic mediators, such as fibronectin and vimentin (~ 1 µM) and weakens the severity of hepatic damage in a murine model of carbon tetrachloride-induced fibrosis and reduces the phosphorylation of Akt and p70S6 kinase (10 mg/kg, p.o., 6d/week for 1 month).A cell permeable imidazopyridine-carboxylate derived compound that acts as a potent and selective inhibitor of phosphatidylinositol 3-kinase a (PI3Ka; IC₅₀= 800 pM).
