pi3kα in 4

PI3Kα-IN-4 is a potent, selective, and orally active PI3Kα inhibitor with an IC50 of 1.8 nM, demonstrating antitumor activity [1].

(S)-PI3Kα-IN-4, a potent inhibitor of PI3Kα with an IC50 of 2.3 nM, demonstrates 38.3-, 4.25-, and 4.93-fold selectivity over PI3Kβ, PI3Kδ, and PI3Kγ, respectively, and is suitable for cancer research[1]. (S)-PI3Kα-IN-4 (compound 11) is a quinazolin-4(3H)-one derivative with 2-substituted-N-methylpropanamide substitution[1].

PI4KIIIbeta-IN-10 is a potent inhibitor of PI4KIIIβ with an IC50 value of 3.6 nM.

PI4KIIIbeta-IN-9 is a potent inhibitor of PI4KIIIβ [IC50 of 7 nM].

AMG 511 is a potent and orally available pan inhibitor of class I PI3Ks (Kis of 4 nM, 6 nM, 2 nM, and 1 nM for PI3Kα, β, δ, and γ, respectively), exhibiting anti-tumor activity in a mouse glioblastoma xenograft model[1]. AMG 511 significantly suppresses PI3K signaling as indicated by a decrease in p-Akt (Ser473).

Bimiralisib (PI3K-IN-2) is an orally bioavailable pan inhibitor of PI3K and inhibitor of the mTOR, with potential antineoplastic activity. PI3K-IN-2 inhibits the PI3K kinase isoforms alpha, beta, gamma and delta and, to a lesser extent, mTOR kinase, which may result in tumor cell apoptosis and growth inhibition in cells overexpressing PI3K mTOR. Activation of the PI3K mTOR pathway promotes cell growth, survival, and resistance to both chemotherapy and radiotherapy.

Onatasertib (CC223) is an orally available mTOR inhibitor with potential antitumor activity. Onatasertib inhibits the activity of mTOR, which may result in the induction of tumor cell apoptosis and a decrease in tumor cell proliferation. Onatasertib is a potent mTOR kinase inhibitor (IC50: 16 nM), with >150-fold sensitivity than the related lipid kinase PI3Kα (IC50: 4 μM).

PI3Kα-IN-17 (example 4), a potent PI3K α inhibitor [1], effectively targets the enzyme.
