Poloppin 

Poloppin 是一种有效的细胞渗透抑制剂，可抑制有丝分裂的 polo 样激酶 (PLK) (IC50=26.9 μM)，并可通过Polo-box 结构域 (PBD) 阻止蛋白之间的相互作用 (Kd= 29.5 μM)。Poloppin 选择性地杀死表达突变 KRAS 的细胞，增强有丝分裂中的死亡。Poloppin 可用作 KRAS 突变型癌症的研究，可作为单一试剂，或与 c-MET 抑制剂联合使用。

生物活性

Poloppin is a potent, cell penetrant inhibitor of the mitotic Polo-like kinase (PLK) (IC50=26.9 μM) and prevents the protein-protein interaction via the Polo-box domain (PBD) (Kd= 29.5 μM). Poloppin selectively kills cells expressing mutant KRAS, enhancing death in mitosis. Poloppin is used for the study of KRAS-mutant cancers as single agents, or in combination with c-MET inhibitors[1].
IC50 & Target

IC50: 26.9 μM (mitotic Polo-like kinase (PLK))
Kd: 26.9 μM (protein-protein interaction via the Polo-box domain (PBD))[1]
体外研究
(In Vitro)

Poloppin (0-200 μM) competitively inhibits the binding of a TAMRA-labeled substrate peptide to the PLK1 PBD, exhibiting an IC50 value of 26.9 μM in an FP assay; the isothermal titration calorimetry of Poloppin binding to the PBD domain of PLK1 with a Kd of 29.5 μM[1].
Poloppin (0-100 μM) triggers a dose-dependent mitotic arrest and induces multiple anomalies in mitosis in cells, the EC50 value is 29.9 μM. In representative images of U2OS cells with 12.5 μM Poloppin, <5% of cells exhibit normal metaphase chromosome alignment, and shows bipolar or disordered spindles and non-congressed chromosomes in cells[1].
Poloppin (0-200 μM; 24 hours) inhibits SW48 isogenic parental or KRAS G12D cells growth with GI50 values of 13.7 μM and 5.3 μM, respectively. It inhibits KRAS wild-type p53 and KRAS MUT p53 MEFs cells with GI50 values of 51.1 and 49.5 μM, respectively. When the medium is added 500nM 4-OH Tamoxifen to the culture media overnight, Poloppin inhibits KRAS wild-type p53 and KRAS MUT p53 MEFs cells with GI50 values of 43.7 μM and 17.6 μM, respectively[1].
Poloppin (0-10 μM; 72 hours) sensitizes mutant KRAS-expressing cells to inhibitors of the c-MET tyrosine kinase. SW48 cell bearing mutant KRAS are sensitized to Poloppin after inhibition of c-MET, the GI50 values of Poloppin combination with Crizotinb (HY-50878) are 0.23 uM and 0.08 uM, respectively in SW48 KRAS WT and KRAS G12D cells. In the contrast, the GI50 values are 0.56 uM and 0.63 uM in SW48 KRAS WT or KRAS MUT cells when treated with Crizotinib alone[1].

体外研究
(In Vitro)

Poloxin (25 μM) induces defects in centrosome integrity, spindle formation, and chromosome alignment in mitosis. Centrosomal fragmentation induced by Poloxin is partially rescued by Kiz T379E. Poloxin (25 μM) activates the mitotic checkpoint, induces apoptosis and inhibits proliferation of MDA-MB-231 cells[1]. Poloxin inhibits proliferation in both cell lines with a comparable efficiency through 72 h period[2]. Poloxin inhibits the polo-box domain (PBD) interaction with an apparent IC50 of ∼4.8 μM. Poloxin exhibits a loose Plk1 PBD specificity with 4-10 times higher IC50 values for Plk2 and Plk3, and does not significantly inhibit other types of phosphopeptide-binding domains such as FHA, WW, and SH2 domains[3].

Poloxin (40 mg/kg) decreases the proliferation of MDA-MB-231 cells, and surpresses the growth of the tumor nude mice bearing established xenografts of MDA-MB-231[1].

Cell Assay
[2]

Cell Viability Assay on treated cells in 96-well plates, based on viable cells. 20 μL of CellTiter-Blue®reagent is added to each well and then incubated at 37°C with 5% CO2 for 4h before fluorescence reading using a Victor 1420 Multilabel Counter. All experiments are performed in triplicate and at least three independent experiments are performed. Data are presented as percentage compared with control.

Animal Administration
[1]

Viable MDA-MB-231 or HeLa cells (1×106) are resuspended in 300 μL of 0.9% NaCl and s.c. injected into both flanks of nude mice (MDA-MB-231: n=8 mice in each group, total N=16; HeLa: n=7 mice in each group, total N=14). Approximately 3 weeks after inoculation, mice are treated with Poloxin (40 mg/kg) or TQ (20 mg/kg) by intratumoral injection on Mondays, Wednesdays, and Fridays for 5 to 6 weeks. The tumor area is calculated by multiplication of the greatest diameter with the perpendicular diameter every 2 to 3 days. Measurements of all tumors within the group are represented by the mean value. U-tests and Student’s t-tests are performed for statistical evaluation among MDA-MB-231 groups and between HeLa groups, respectively. All mice are properly treated in accordance with the guidelines of the local animal committee.
