产品描述 | Bafetinib (INNO-406) (INNO-406) is an effective and specific dual Bcr-Abl/Lyn inhibitor (IC50: 5.8/19 nM), and no inhibition of the phosphorylation of the T315I mutant and less effective to c-Kit and PDGFR. |
靶点活性 | Abl:5.8 nM, Lyn:19 nM |
体外活性 | Bafetinib通过阻断WT Bcr-Abl自磷酸化及其下游激酶活性,对K562和293T细胞的IC50分别为11 nM和22 nM,有效抑制包括K562、KU812和BaF3/wt在内的Bcr-Abl阳性细胞系的生长,对Bcr-Abl阴性的U937细胞系增殖无影响。此外,Bafetinib对Bcr-Abl点突变细胞系(例如BaF3/E255K细胞)展示了剂量依赖的抗增殖效果。[1] 在Bcr-Abl阳性白血病细胞系中,Bafetinib通过阻断Bcr-Abl的磷酸化,诱导包括半胱天冬酶介导和非半胱天冬酶依赖的细胞死亡。[2] |
体内活性 | 在Bcr-Abl阳性的KU812小鼠模型中,Bafetinib(0.2 mg/kg/天)显著抑制肿瘤生长,在20 mg/kg/天的剂量下能完全抑制肿瘤生长,并且没有不良反应。对于Balb/c小鼠,Bafetinib的最大耐受剂量为200 mg/kg/d,生物可利用度(BA)值为32%。[1] 在携带Ba/F3/wt bcr-ablGFP、Ba/F3/Q252H或Ba/F3/M351T细胞的中枢神经系统(CNS)白血病模型中,Bafetinib(60 mg/kg)和环孢霉素A(CsA)(50 mg/kg)的组合治疗比单独使用Bafetinib或CsA更显著地抑制了大脑中白血病的生长。[3] |
激酶实验 | Kinase assay : Bcr-Abl kinase assays are performed in 25 μL of reaction mixture containing 250 μM peptide substrate, 740 Bq/μL [γ-33P]ATP, and 20 μM cold adenosine triphosphate (ATP) by using the SignaTECT protein tyrosine kinase assay system. Each Bcr-Abl kinase is used at a concentration of 10 nM. Kinase assays for Abl, Src, and Lyn are carried out with an enzyme-linked immunosorbent assay (ELISA) kit. The inhibitory effects of NS-187 against 79 tyrosine kinases are tested with KinaseProfiler. |
细胞实验 | K562, BaF3/wt, BaF3/E255K, and BaF3/T315I cells are plated at 1 × 103 in 96-well plates, whereas KU812 and U937 cells are plated at 5 × 103 in 96-well plates. Cells are incubated with serial dilutions of Bafetinib for 3 days. Cell proliferation is measured by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; Nacalai Tesque) assay, and the 50% inhibitory concentration (IC50) values are calculated by fitting the data to a logistic curve.
