Brigatinib

SKU: orb1226819

Description

Brigatinib (AP-26113, AP26113) is a potent, selective, second generation ALK inhibitor with IC50 of 0.62 nM, exhibits about fivefold greater potency in vitro compared with crizotinib; shows high activity against both sensitive and resistant H3122 cells, decreasing cell growth, suppressing ALK phosphorylation, and inducing apoptosis; AP26113 is also active in Ba/F3 cells expressing either native or mutant EML4-ALK with IC50 of 10 and 24 nM, respectively; demonstrates promising activity in crizotinib resistant.Lung Cancer Approved.

Bioactivity

• In Vivo:
  Brigatinib (10, 25, or 50 mg/kg once daily, p.o.) leads to a dose-dependent inhibition of tumor growth in ALK+ Karpas-299 (ALCL) and H2228 (NSCLC) xenograft mouse models. Brigatinib markedly enhances survival of mice bearing ALK+ brain tumors compared with PF-02341066. Brigatinib (10, 25, 50 mg/kg, p.o.) results in dose-dependent antitumor activity, with tumor regressions in a mouse model of NSCLC.
• In Vitro:
  Brigatinib potently inhibits the in vitro kinase activity of ALK (IC50, 0.6 nM) and all five mutant variants tested, including G1202R (IC50, 0.6-6.6 nM). Brigatinib demonstrates a high degree of selectivity, only inhibiting 11 additional native or mutant kinases with IC50 <10 nM. These include ROS1, FLT3, and mutant variants of FLT3 (D835Y) and EGFR (L858R; IC50, 1.5-2.1 nM). Brigatinib exhibits more modest activity against EGFR with a T790M resistance mutation (L858R/T790M), native EGFR, IGF1R, and INSR (IC50, 29-160 nM) and does not inhibit MET (IC50 >1000 nM). In cellular assays, brigatinib inhibits ALK and ROS1 with IC50s of 14 and 18 nM, respectively. Brigatinib inhibits FLT3 and IGF-1R with about 11-fold lower potency (IC50, 148-158 nM) and inhibits mutant variants of FLT3 and EGFR with 15- to 35-fold lower potency (IC50, 211-489 nM). Brigatinib inhibits cell growth with GI50 values ranging from 503 to 2, 387 nM in three ALK-negative ALCL and NSCLC cell lines. Brigatinib inhibits ALK activity and abrogates proliferation of ALK addicted neuroblastoma cell lines, with IC50 of 75.27 ± 8.89 nM. Brigatinib inhibits both the ALK-I1171N and the ALK-G1269A mutant receptors at 10 and 4 nM levels, respectively.
