PI 3-Kα Inhibitor VIII is a cell-permeable imidazopyridine compound that acts as a highly potent and ATP-competitive DNA-PK and p110α-selective PI 3-kinase inhibitor (IC50 = 0.3, 40, 100, and 850 nM for p110α, p110γ, PI 3-K C2β, and p110β, respectively). PI 3-Kα Inhibitor VIII may act to effectively block cellular PI 3-kinase/Akt signaling and inhibit tumor growth both in vitro (IC50 ≤58 nM in MCF7, MCF7 ADR-res, HeLa, A375, and A549 cultures) and in mice in vivo (62% inhibition of HeLa xenograft in 2 weeks, 50 mg/kg/day, i.p.).
