| Hazard Information | Back Directory | [Description]
HS-173 is an imidazopyridine analog that acts as a PI3Kα inhibitor with an IC50 value of 0.8 nM.1 It demonstrates antiproliferative activity in T47D, SK-BR-3, and MCF-7 cells with IC50 values of 0.6, 1.5, and 7.8 μM, respectively.1 HS-173 is reported to induce apoptosis by arresting the cell cycle at the G2/M phase and by activating caspases.2,3 It has also been shown to block VEGF-induced angiogenesis both in vitro and in vivo.2 | [Uses]
HS-173 is a potent PI3Kα inhibitor with anticancer activity. | [in vitro]
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-1a and vegf which play an important role in angiogenesis. this effect was confirmed by the suppression of tube formation and migration assay in vitro [1]. | [in vivo]
hs-173 diminished blood vessel formation in the matrigel plug assay in mice. these results suggest that hs-173 has potent anti-angiogenic activity in vivo [1]. | [target]
