GSK2126458 is a potent inhibitor of phosphoinositide 3-kinase isoforms (K
is = 19, 130, 24, and 60 pM for p110α, β, δ, and γ, respectively).
1 It also inhibits mTOR in both mTORC1 and mTORC2 (K
is = 180 and 300 nM, respectively), as well as several common mutant forms of p110α.
1 GSK2126458 is orally bioavailable, displays favorable pharmacokinetics, and shows efficacy in tumor growth models.
1 GSK2126458 positively combines with inhibitors of discoidin domain receptor 1 (DDR1) inhibitor DDR1-IN-1 (Item No.
