名称 | PHA-767491 hydrochloride |
描述 | PHA-767491 hydrochloride (CAY-10572 hydrochloride) is an effective ATP-competitive dual Cdc7/CDK9 inhibitor (IC50: 10/34 nM). It has ~20-fold selectivity against GSK3-β and CDK1/2, 50-fold selectivity against CDK5 and MK2, 100-fold selectivity against CHK2 and PLK1. |
细胞实验 | For assays in 96 well plates 2500 cells are plated per well. After 24 hours, cells are treated with small molecule inhibitors and incubated for 72 hours at 37°C. Subsequently the cells are lysed and the ATP content is measured as an indicator of metabolically active cells using the CellTiter-Glo assay. IC50 values are calculated using the GraphPad software. For assays in six-well plates, 100,000 cells are plated per well. After 24 hours, cells are treated with small molecule inhibitors and incubated for varying time points. Cells are trypsinized and a suspension is made in 5 mL of phosphate buffered saline. 30 μL of this suspension is mixed with 30 μL of CellTiter-Glo reagent followed by a 10-minute incubation at room temperature. Luminescence is measured using EnVision 2104 Multilabel Reader and BioTek Synergy Neo Microplate Reader. |
激酶实验 | 20 ng of purified human DDK is pre-incubated with increasing concentrations of each DDK inhibitor for 5 min. Then 10 μCi (γ)-32P ATP and 1.5 μM cold ATP are added in a buffer containing 50 mM Tris-HCl (pH 7.5), 10 mM MgCl2, and 1 mM DTT and incubated for 30 min at 30°C. The proteins are denatured in 1X Laemmli buffer at 100°C followed by SDS-PAGE and autoradiography on HyBlot CL film. Auto-phosphorylation of DDK is used as an indicator of its kinase activity. 32P-labeled bands are quantified using ImageJ and the IC50 values are calculated using GraphPad. |
体外活性 | PHA-767491对HCC1954细胞(IC50:0.64μM)和Colo-205细胞(IC50:1.3μM)的增殖具有抑制作用,并且是体外DDK抑制剂(IC50:18.6nM)。PHA-767491(2μM)在24小时内完全消除HCC1954细胞中Mcm2的磷酸化[1]。PHA-767491与5-FU联合使用时,表现出更强的细胞毒性,并通过显著增加caspase 3激活和poly(ADP-Ribose) polymerase分裂来诱导HCC细胞中显著的凋亡。PHA-767491直接抵消了5-FU诱导的Chk1磷酸化,并减少了抗凋亡蛋白myeloid leukemia cell line的表达[2]。PHA-767491(0-10μM)以时间和剂量依赖的方式减少了U87-MG和U251-MG细胞的活性(IC50:约2.5μM)。 |
体内活性 | PHA-767491 降低了 Chk1 磷酸化,并在裸鼠 HCC 移植瘤组织切片中增加了原位细胞凋亡。 |
存储条件 | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice. |
溶解度 | H2O : 25 mg/mL (100 mM) DMSO : 4.62 mg/mL (18.48 mM), Sonication is recommended.
