名称 | DASA-58 |
描述 | DASA-58 is a specific and potent Pyruvate kinase M2 (PKM2) activator. |
激酶实验 | CDK kinase assay: Kinase assays are performed in 96-well polypropylene plates. Each reaction contained 2 μg of histone H1 at a final concentration of 10 μM [γ-33P]ATP (0.2 μCi/well; approximately twice the experimentally determined Km), 10 mM MgCl2, 1 mM DTT, 0.01% Triton X-100, and 10% glycerol in a 40 μL volume. The reaction is initiated with the addition of 20 μL enzyme (6 ng cdk2/well resulting in a final concentration of 1.6 nM), which is previously diluted 1:50–1:200 in the same buffer, and allowed to proceed for 1 h at room temperature. Reaction is stopped by the addition of 0.01 mL 10% phosphoric acid, and 25 μL of reaction mixture is transferred to P30 phosphocellulose filter mat paper. The filter mat is washed three times with 1.0% phosphoric acid, air dried, and then counted for radioactivity in a liquid scintillation counter. The cdk4 kinase assay for cyclin D1-cdk4 is carried out in a polypropylene 96-well microtiter plate format measuring the incorporation of radioactive phosphate into GST-Rb. Purified cyclin D1-cdk4 is incubated with 1 μg GST-Rb in 20 mM HEPES (pH 7.5) in the presence of 10 mM MgCl2, 1 mM DTT, 0.01% Triton X-100, and 10% glycerol. The final cdk4 concentration is 10 ng/well, or 1.6 nM. Kinase reaction is initiated by the addition of ATP at a final concentration of 10 μM ATP (twice the experimentally determined Km) and [γ-33P]ATP (1.0 μCi per well) in a 60-μL volume and allowed to proceed at room temperature for 1 h. Reaction is stopped by the addition of 0.01 ml 10% phosphoric acid, and 25 μL of reaction mixture is transferred to P30 phosphocellulose filter mat paper. The filter mat is treated as for Cdk1/Cdk2 assays. |
体外活性 | DASA-58在抑制LPS诱导的Hif-1α和IL-1β表达,以及一系列其他依赖Hif-1α的基因在初代BMDMs中的表达方面发挥作用,并且还能抑制LPS激活的巨噬细胞中的糖酵解过程和琥珀酸的积累。[1] 在PC3细胞中,DASA-58通过恢复PK活性和消除PKM2的核内转移及其与HIF-1α的关联,破坏了由基质诱导的EMT程序。同时,DASA-58还显著减少(约6倍)CAF诱导的PC3细胞肺转移瘤的形成。[2] |
体内活性 | DASA-58 (40 μM) 对前列腺癌的上皮-间质转化(EMT)及在SCID小鼠中的肿瘤扩散产生影响。[2] |
