描述:

BEZ235 (NVP-BEZ235, Dactolisib) 是一种双重ATP竞争性 PI3K 和 mTOR 抑制剂,在无细胞试验中,抑制 p110α/γ/δ/β 和 mTOR(p70S6K) 的 IC50 分别为 4 nM /5 nM /7 nM /75 nM /6 nM。 在 3T3TopBP1-ER 细胞中抑制 ATR,IC50 为 21 nM,而对 Akt 和 PDK1 的抑制作用很弱。

溶解性:DMF :18 mg/mL warmed (38.33 mM)
DMSO : 5.2 mg/mL (11.07 mM; Need ultrasonic and warming)

体外研究:

BEZ235 significantly reduces the phosphorylation levels of the mTOR activated kinase p70S6K. BEZ235 results in a reduction of S235/S236P-RPS6 levels with IC50 of 6.5 nM. The activity of BEZ235 against mTOR is determined using a biochemical mTOR K-LISA assay with IC50 of 20.7 nM. BEZ235 shows slightly lower activity against its β paralogue with IC50 of 75 nM. The PI3K/Akt/mTOR pathway is often constitutively activated in human tumor cells. BEZ235 blocks PI3K and mTOR kinase activity by binding to the ATP-binding cleft of these enzymes. Both PTEN-null cell lines PC3M and U87MG show a dose-dependent reduction in cell proliferation when treated with increasing concentrations of BEZ235 with an average GI50 of 10-12 nM. BEZ235 is an mTORC1/2 catalytic inhibitor.

体内研究:BEZ235 induces regression of the tumors (69%) without statistically significant effect on body weight gain. Altogether, these preliminary in vivo efficacy results show that BEZ235 causes disease stasis when administered orally as a single agent and can enhance the efficacy of other anticancer agents when used in combination studies.
