Brigatinib

Synonyms: AP26113

Brigatinib is a potent and selective ALK (IC50, 0.6 nM) and ROS1 (IC50, 0.9 nM) inhibitor. It also inhibits IGF-1R, FLT3, and mutant variants of FLT3 (D835Y) and EGFR with lower potentcy.

Biological Activity

Description Brigatinib is a potent and selective ALK (IC50, 0.6 nM) and ROS1 (IC50, 0.9 nM) inhibitor. It also inhibits IGF-1R, FLT3, and mutant variants of FLT3 (D835Y) and EGFR with lower potentcy.

0.37 nM 1.9 nM 2.1 nM 24.9 nM 39.9 nM
In vitro
In vitro Beyond ALK, IGF1R, and InsR, brigatinib also potently inhibits FLT3 and ROS1 with IC50 values of 2.1 and 1.9 nM, respectively. It does not show significant activity toward c-Met or Ron up to 1 μM[1]. Brigatinib overcomes the resistance of EGFR-triple-mutant and the activity depends on ATP-competitive manner with less affection to wild-type EGFR[2].
Cell Research Cell lines U937 cells, Karpas-299 cells, H3122 cells
Concentrations --
Incubation Time 72 h
Method

All cell lines were used within 20 passages of the initial thaw. Following inhibitor treatment for 72 h, cell growth was assessed to determine the concentration that causes 50% inhibition of cell viability (IC50).

In Vivo
In vivo Mouse PK parameters for Brigatinib following oral dosing (10 mg/kg): Cmax=448 ng/mL,t1/2=5.8 h. And in CD rats, after dosing at 3 mg/kg i.v, CL=0.46 L/(h·kg), t1/2=4.8 h, Vss=7.8 L/kg; Dosed at 10 mg/kg p.o, Cmax=305 ng/mL, tmax=4 h, t1/2=3.4 h， F%=52. Brigatinib demonstrates dose-dependent antitumor activity[1]. Brigatinib demonstrates growth inhibition activity in PC9 triple-mutant xenograft model and in combination with anti-EGFR antibody to potentiate the efficacy both in vitro and in vivo as shown in first-generation EGFR-TKI-resistant patients[2].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
