pi3kα-h1047r

ETP-46321 is an effective and orally bioavailable PI3Kα/PI3Kδ inhibitor (Ki: 2.3/14.2 nM).

PKI-402 is a potent PI3K and mTOR inhibitor. PKI-402 inhibits PI3Kα, mTOR, PI3Kβ, PI3Kδ and PI3Kγ with IC50s of 2, 3, 7, 14 and 16 nM, respectively.

Gedatolisib (PF-05212384) is a highly effective dual inhibitor targeting the PI3Kα/γ (IC50: 0.4/5.4 nM)and mTOR (IC50: 1.6 nM) in the PI3K/mTOR signaling pathway.

PI3Kα-IN-23 (Compound 9) is an inhibitor of PI3Ka H1047R.

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.

PKI-179 is a potent, orally active compound that functions as a dual PI3K/mTOR inhibitor. It demonstrates IC50 values of 8 nM for PI3K-α, 24 nM for PI3K-β, 74 nM for PI3K-γ, 77 nM for PI3K-δ, and 0.42 nM for mTOR. Additionally, it is effective against E545K and H1047R mutations, with IC50s of 14 nM and 11 nM, respectively. In vivo studies have shown that PKI-179 possesses anti-tumor capabilities[1][2].

PKI-179 is an orally bioavailable dual inhibitor of PI3K and mammalian target of rapamycin (mTOR). In an in vitro enzymatic assay, it potently inhibits PI3K (IC50s = 8, 24, 17, and 74 nM for isoforms α, β, δ, and γ, respectively), two common PI3Kα mutants, E545K and H1047R (IC50s = 14 and 11 nM, respectively), and mTOR (IC50 = 0.42 nM). PKI-179 is selective for PI3K and mTOR over a panel of 361 other kinases at IC50 values up to 50 μM, hERG (IC50 > 30 μM), and cytochrome P450 (CYP) isoforms (IC50s > 30 μM), but does have activity for CYP2C8 (IC50 = 3 μM). It inhibits proliferation through the Akt/mTOR signaling pathway in MDA-361 breast and PC3MM2 prostate cancer cell lines in vitro (IC50s = 22 and 29 nM, respectively) and inhibits tumor growth in an MDA-361 mouse xenograft model when used at a dose of 50 mg/kg.

AZD-8835 is a mixed inhibitor of PI3Kα/δ (IC50: 6.2/5.7 nM), also with selectivity against PI3Kβ/γ (IC50: 431/90 nM).

PI3Kα-IN-22 (Compound 17) is a potent, selective, and orally active inhibitor targeting the PI3Kα H1047R mutation, exhibiting an IC 50 of 1 nM in the pAKT T47D AlphaLISA assay. It has demonstrated the ability to induce tumor regressions in the HCC1954 tumor model in mice [1].
