靶点:p110α:52 nM (IC50);p110β:166 nM (IC50);p110δ:116 nM(IC50);p110γ:262 nM (IC50) Vps34:2.4 μM (IC50);p110α-H1047R:58 nM (IC50);p110α-E545K:99 nM (IC50);mTOR:4.6μM (IC50)
体外研究:Buparlisib (NVP-BKM120) exhibits 50-300 nM activity for class I PI3K’s, including the most common p110α mutants. Additionally, NVP-BKM120 exhibits lower potency against class III and class IV PI3K's, where 2, 5, >5, and >25 μM biochemical activity is observed for inhibition of VPS34, mTOR, DNAPK, and PI4K, respectively. Buparlisib (NVP-BKM120) induces multiple myeloma (MM) cell apoptosis in both dose- and time-dependent manners. Buparlisib (NVP-BKM120) at concentrations ≥10 μM induces significant apoptosis in all tested MM cell lines at 24 h (P<0.05, compares with control). Therefore, 10 μM Buparlisib (NVP-BKM120) and 24-h treatment are chose in in the following experiments if not stated otherwise. Buparlisib (NVP-BKM120) treatment results in a dose-dependent growth inhibition in all tested MM cell lines. Buparlisib (NVP-BKM120) IC50 varies among tested MM cells. At 24 h treatment, IC50 for ARP-1, ARK, and MM.1R is between 1 and 10 μM, while IC50 for MM.1S is <1 μM, and IC50 for U266 is between 10 and 100 μM. In summary, NVP-BKM120 treatment results in MM cell growth inhibition and apoptosis in dose- and time-dependent manners.
体内研究:In A2780 xenograft tumors, oral dosing of Buparlisib (NVP-BKM120) at 3, 10, 30, 60, and 100 mg/kg results in a dose dependent modulation of pAKTSer473. Partial inhibition of pAKTSer473 is observed at 3 and 10 mg/kg, and near complete inhibition is observed at doses of 30, 60, or 100 mg/kg, respectively. Inhibition of pAKT (normalized to total AKT) tracked well with both plasma and tumor drug exposure. Mice receiving Buparlisib (NVP-BKM120) (5 μM per kg per day for 15 days) treatment has significantly smaller tumor burdens as compare with control mice, which are measured as tumor volume (P<0.05) and level of circulating human kappa chain (P<0.05). In addition, NVP-BKM120 treatment significantly prolongs the survival of tumor-bearing mice (P<0.05).
激酶实验:PI3K 生化实验(ATP 消耗实验): BKM120溶于DMSO中,按每孔1.25 µL直接加到黑色384孔板上。开始反应, 25 µL 10nM PI3K和5 µg/mL 1-α-磷酸肌醇(PI)加到实验 buffer (10 mM Tris pH 为7.5, 5 mM MgCl2, 20 mM NaCl, 1 mM DTT,及0.05% CHAPS),然后加到每孔中,随后在实验buffer中加入25 µL 2 µM ATP。反应进行直到50% ATP被消耗,然后加入25 µL KinaseGlo溶液终止反应。终止的反应温育5分钟,然后通过荧光测定残留的ATP。
