NVP-BKM120 hydrochloride

Research use only, not for human use.

A potent, selective, orally bioavailable inhibitor of class I PI3K isoforms.

A potent, selective, orally bioavailable inhibitor of class I PI3K isoforms with IC50 of 52 nM/166 nM/116 nM/262 nM for p110α/β/δ/γ, respectively; much less effectively inhibits the class III PI3K Vps34 and mTOR, and has no effect on PI4Kβ and several other kinases; prevents the growth of assorted cancer cell lines when used at 5 μM and inhibits tumor growth in vivo.Blood Cancer Phase 2 Clinical.

Buparlisib (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 (BKM120) induces multiple myeloma (MM) cell apoptosis in both dose- and time-dependent manners. Buparlisib (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 (BKM120) and 24-h treatment are chose in in the following experiments if not stated otherwise. Buparlisib (BKM120) treatment results in a dose-dependent growth inhibition in all tested MM cell lines. Buparlisib (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, Buparlisib (BKM120) treatment results in MM cell growth inhibition and apoptosis in dose- and time-dependent manners.

In A2780 xenograft tumors, oral dosing of Buparlisib (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 (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, Buparlisib (BKM120) treatment significantly prolongs the survival of tumor-bearing mice (P<0.05).
