pi3kα-h1047r

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.

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).

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

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.

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.

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].
