We synthesized a novel imidazopyridine analogue, a PI3Kα inhibitor HS-173 and investigated anti-cancer capacity in human cancer cells. HS-173 inhibited the PI3K signaling pathway, and showed anti-proliferative effects on cancer cells. Also, HS-173 induced cell cycle arrest at the G2/M phase and apoptosis. In addition, HS-173 decreased the expression HIF-1α and VEGF which play an important role in angiogenesis. This effect was confirmed by the suppression of tube formation and migration assay in vitro. Furthermore, HS-173 diminished blood vessel formation in the Matrigel plug assay in mice. Therefore, HS-173 is considered as a novel drug candidate to treat cancer patients.
► HS-173 inhibited the PI3K/Akt/mTOR pathway in cancer cells. ► HS-173 suppressed cell growth/proliferation and angiogenesis. ► HS-173 induced apoptosis accumulating G2/M phase of cell cycle.
