Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	2%DMSO 1 40%PEG300 2 2%Tween80 3 56%ddH2O この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。	4.000mg/ml (8.02mM)	Taking the 1 mL working solution as an example, add 20 μL of 200 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 560 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Avapritinib is a small molecule kinase inhibitor that potently inhibits PDGFRα D842V mutant activity in vitro (IC50 = 0.5 nM) and PDGFRα D842V autophosphorylation in the cellular setting (IC50 = 30 nM); also a potent inhibitor of the analogous Kit (c-Kit) mutation, D816V in Kit (c-Kit) Exon 17 (IC50 = 0.5 nM).
in vitro	Avapritinib (BLU-285) is a selective oral inhibitor that targets KIT Exon 17 and PDGFRα D842 activation loop mutants. Cellular assays measuring inhibition of KIT mutant autophosphorylation confirm its activity against the KIT D816 mutants D816V (HMC1.2 cells, IC50 = 3 nM) and D816Y (P815 cells, IC50 = 22 nM) as well as other KIT Exon 17 mutants such as N822K (Kasumi cells, IC50 = 40 nM) found in treatment-refractory GIST^[1].
in vivo	In vivo, Avapritinib (BLU-285) is a well-tolerated, orally bioavailable agent that achieves dose dependent tumor growth inhibition in a D816Y-driven xenograft model. A PK-PD-efficacy relationship with this compound has been established demonstrating that tumor regression results from >90% target suppression and is observed with 30 mg/kg once daily dosing. With potent activity against PDGFRα D842V and KIT Exon 17 mutants, it targets previously unaddressed genomic drivers of disease and provides promise for the treatment of PDGFRα D842V-driven GIST(gastrointestinal stromal tumor) or SM(systemic mastocytosis), where more than 90% of patients carry the KIT D816V mutation. Besides single agent activity, the highly selective BLU-285 offers an opportunity for combination with other agents in GIST to cover the entirety of KIT primary and resistance mutants^[1].
