靶点活性 | Aurora B:135 nM, Aurora A:27 nM, Aurora C:120 nM |
体外活性 | PHA-680632对所有三种Aurora激酶(A、B和C)具有强大的抑制作用,其IC50值分别为27、135和120 nM。PHA-680632选择性抑制Aurora激酶,对FGFR1、FLT3、LCK、PLK1、STLK2、VEGFR2和VEGFR3的IC50值高出10至200倍,对另外22种激酶的IC50值高于10 μM。PHA-680632在广泛的细胞类型中显示出强大的抗增殖效果,其IC50值为0.06–7.15 μM,包括HeLa、HCT116、HT29、LOVO、DU145和NHDF细胞。PHA-680632(0.5 μM)会在肿瘤细胞中引起多倍体。PHA-680632的作用机制与抑制Aurora激酶一致。[1] PHA680632与辐射联合使用在癌细胞中产生加成效应,特别是在p53缺陷细胞中。联合使用离子辐射(IR)和PHA680632(100–400 nM)处理,然后进行IR,可在具有p53缺陷的HCT116细胞中,仅增强辐射诱导的Annexin V阳性细胞、微核形成和Brca1焦点形成,而不影响p53野生型对应物。[2] |
体内活性 | HA-680632 (15–60 mg/kg) 在小鼠异种移植模型中,通过减少肿瘤细胞增殖并增加凋亡,抑制了HL60、A2780和HCT116细胞的肿瘤生长。PHA-680632 (45 mg/kg) 抑制了小鼠乳腺瘤病毒v-Ha-ras转基因小鼠中活化ras驱动的乳腺肿瘤生长,导致肿瘤完全稳定和部分回归。[1] |
激酶实验 | Aurora Kinase Inhibition Assay: Inhibition of kinase activity by PHA-680632 is assessed using a scintillation proximity assay format. The biotinylated substrate is transphosphorylated by the kinase in presence of ATP traced with γ33-ATP. The phosphorylated substrate is then captured using streptavidin-coated scintillation proximity assay beads and the extent of phosphorylation is evaluated by β-counter after a 4-hour rest for the floatation of the beads on a dense 5 M CsCl solution. In particular, a peptide derived from the Chocktide sequence (LRRWSLGL) is used as substrate for Aurora A, whereas the optimized peptide Auroratide is employed for Aurora B and C. The assay is run in a robotized format on 96-well plates. The potency of the compound toward Aurora kinases is evaluated and IC50 values are determined. |
细胞实验 | Cells (5 × 103 to 1.5 × 104 per cm2) are seeded in 24-well plate. After 24 hours, plates are treated with PHA-680632 and incubated for 72 hours. At the end of incubation time, cells are detached from each plate and counted using a cell counter. IC50s are calculated using percentage of growth versus untreated cont(Only for Reference) |
