Description

BAY 80-6946 is an ATP-competitive selective class-IPI3kinases inhibitor, withIC50s of 0.5, 0.7, 3.7 and 6.4 nM forPI3Kα,PI3Kδ,PI3KβandPI3Kγ, and much less active against mTOR (IC50=45 nM) and other PIKs (no inhibition at 1 μM).

IC50& Target

IC50: 0.5 nM (PI3Kα), 0.7 nM (PI3Kδ), 3.7 nM (PI3Kβ), 6.4 nM (PI3Kγ)[1]

In Vitro

BAY 80-6946 potently inhibits the catalytic activity of the class I PI3Kα, β, γ, and δ isoforms with IC50s of 0.5, 3.7, 6.4, and 0.7 nM, respectively. BAY 80-6946 shows significantly weaker activity against mTOR with an IC50of 45 nM. In KPL4 cells, BAY 80-6946 reduces basal levels of AKT phosphorylation at both Thr308 and Ser473 with IC50values of 0.4 and 0.6 nM, respectively. BAY 80-6946 has mean IC50values of 19 nM against cell lines withPIK3CA-activating mutations (n = 9) and 17 nM against HER2-positive cell lines (n=7), whereas the activity inPIK3CAwild-type and HER2-negative cells is about 40-fold less potent (average IC50=774 nM; n=11)[2].

In Vivo

BAY 80-6946 is highly efficacious in a variety of human tumor xenograft models derived from different tumor indications that exhibit an activated PI3K pathway. BAY 80-6946 is administered at 0.5 to 6 mg/kg i.v. every second day for a total of five doses starting on day 14, following tumor cell implantation. On day 25, 3 days after the last dose, TGI rates of 77%, 84%, 99%, and 100% are observed with BAY 80-6946 at doses of 0.5, 1, 3, and 6 mg/kg, respectively. Complete tumor regression is shown in 10 of 10 rats in the 3 and 6 mg/kg groups, and all rats remained tumor free at the termination of the study on day 73. Tumor growth delays more than 25 days are observed in the 0.5 and 1 mg/kg dose groups[2].
