产品描述 | Vactosertib (EW-7197) is an orally bioavailable inhibitor of the serine/threonine kinase, transforming growth factor (TGF)-beta receptor type 1 (TGFBR1), also known as activin receptor-like kinase 5 (ALK5), with potential antineoplastic activity. |
靶点活性 | ALK4:13 nM, ALK5:11 nM |
体外活性 | 在HaCaT (3TP-luc) 和 4T1 (3TP-luc) 稳定细胞中,12b 强效抑制TGF-β1诱导的荧光素酶报告活性,其IC50分别为16.5和12.1 nM。[1] Vactosertib抑制TGFβ诱导的Smad2或Smad3磷酸化以及TGFβ处理的乳腺癌细胞中的上皮-间充质转换(EMT)。此外,Vactosertib还能阻断TGFβ1诱导的乳腺细胞中肿瘤细胞迁移和侵袭。[3] |
体内活性 | 在大鼠中,Vactosertib的口服生物利用度为51%,体内曝光高(AUC为1426 ng×h/mL),最大血浆浓度(Cmax)为1620 ng/mL。Vactosertib对心血管系统、中央神经系统和呼吸系统的毒性低。[1] 在小鼠B16黑色素瘤模型中,Vactosertib(每天2.5 mg/kg,口服)抑制了黑色素瘤的进展,增强了细胞毒性T淋巴细胞(CTL)的反应。[2] Vactosertib提高了4T1原位接种小鼠的细胞毒性T淋巴细胞活性,并延长了携带4T1-Luc和4T1乳腺肿瘤的小鼠的生存时间。[3] |
激酶实验 | Protein Kinase Assay: A radioisotopic protein kinase assay (HotSpot assay) is performed at Reaction Biology Corporation. |
细胞实验 | Cells are seeded in 96 well plate and treated with indicated concentrations of EW-7197 in 0.2% HI-FBS medium for 72 h. Cells are dried after incubation with 10% TCA in media. Then, cells are incubated with 0.4% SRB (Sulforhodamine B) in 1% acetic acid for 30 min. After washing with 1% glacial acetic acid, bounded dye is released in 10 mM Tris buffer (pH 10.5) for 30 min. Absorbance is measured at 570 nm. (Only for Reference) |
