Description

General description

A cell-permeable imidazopyridine compound that acts as a highly potent and ATP-competitive DNA-PK and p110α-selective PI3-K inhibitor (IC₅₀ = 0.3, 40, 100, and 850 nM for p110α, p110γ, PI 3-K C2β, and p110β, respectively). Shown to effectively block cellular PI3-K/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.).
