NVP-BEZ 235

Description

NVP-BEZ235 (915019-65-7) is a dual PI3K and mTOR kinase inhibitor.1?It inhibits VEGF-induced proliferation and angiogenesis.2?Reverses lapatinib resistance.3?It induces G1 arrest and reduces cyclin D1 expression in melanoma cells with negligible apoptosis.4?NVP-BEZ235 inhibits the growth of cancer cells with activating PI3K mutations.5?The ability of NVP-BEZ235 to inhibit PI3K has come into question. This study also shows it to be a potent inhibitor of PRKDC (IC50 = 29 nM), ATM (IC50 = 13 nM), and ATR (IC50 = 8 nM).6?Active in vivo.

The Uses of NVP-BEZ 235

Inhibitor of phosphatidylinositol 3-kinases, P13K and mTOR.

The Uses of NVP-BEZ 235

A dual ATP-competitive inhibitor of PI3K and mTOR. p110α, IC50=4 nM; p110β, IC50=75 nM; p110δ, IC50=7 nM; p110γ, IC50=5 nM.

The Uses of NVP-BEZ 235

Phosphatidylinositol 3-kinase (PI3K) signaling through Akt/PKB and the mammalian target of rapamycin (mTOR) controls gene expression related to cell proliferation, differentiation, and apoptosis. Increased activity of this pathway is important in many types of cancer. NVP-BEZ235 is a potent dual inhibitor of PI3K and mTOR that is well tolerated, displays disease stasis when administered orally, and enhances the efficacy of other anticancer agents when used in in vivo combination studies. It inhibits PI3K isoforms and mutants with low nanomolar IC50 values, leading to growth arrest in the G1 phase. Through its effects on PI3K, NVP-BEZ235 inhibits VEGF-induced angiogenesis. By directly blocking cell growth and indirectly inhibiting angiogenesis, it has potential in both solid tumors and in metastatic melanoma therapy.[Cayman Chemical]

What are the applications of Application

BEZ235 is a dual PI3K and mTOR inhibitor

Definition

ChEBI: An imidazoquinoline that is 3-methyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-c]quinoline substituted at position 1 by a 4-(1-cyanoisopropyl)phenyl group and at position 8 by a quinolin-3-yl group. A dual PI3K/mTOR inhibitor used in cancer treatment.

in vivo

BEZ235 induced tumor regression (69%) without a statistically significant effect on weight gain. Taken together, these preliminary in vivo efficacy findings suggest that BEZ235 blocks disease progression when administered orally alone and enhances efficacy when combined with other anticancer drugs.
