Description: BAY1082439 is an orally bioavailable inhibitor of the class I phosphoinositide 3-kinase (PI3K) alpha and beta isoforms with potential antineoplastic activity. PI3K alpha/beta inhibitor BAY1082439 selectively inhibits both PI3K alpha, including mutated forms of PIK3CA, and PI3K beta in the PI3K/Akt/mTOR pathway, which may result in tumor cell apoptosis and growth inhibition in PI3K-expressing and/or PTEN-driven tumor cells. By specifically targeting class I PI3K alpha and beta, this agent may be more efficacious and less toxic than pan PI3K inhibitors.

Additional Information

BAY1082439 is a highly selective PI3Kα/α-balanced inhibitor. BAY 1082439 represents a new type of PI3K inhibitor with unique pharmacological and pharmacodynamic properties. BAY 1082439 has an IC50 ratio of 1:3 in biochemical assays of PI3Kα (4.9 nM) vs. PI3Kα (15.0 nM), and >1000-fold selectivity against mTOR kinase. In vivo, BAY 1082439 showed clear advantages over the strong PI3Kα inhibitor BAY 80-6946 in PTEN/PI3Kα-driven tumor models (e.g., PC3 and HEC-1B), when the two compounds were compared at their MTDs. Furthermore, BAY 1082439 has unique pharmacokinetic (PK) properties with very high plasma free fractions across all species tested (33-50%), large Vss, high clearance and intermediate T1/2.   BAY 1082439 showed strong p-AKT inhibition at 2 and 5 hours post-treatment while p-AKT returned to levels comparable to the vehicle group at 24 hours in all 4 tumor models tested. Interestingly, with once daily dosing, BAY 1082439 could induce tumor regression in KPL4 (PIK3CAmut and HER2+), and tumor stasis in HEC-1B (PTENdel) and in HEC-1A (PIK3CAmut) tumor models.
