    生物活性

    Defactinib hydrochloride (VS-6063 hydrochloride; PF 04554878 hydrochloride) is a novel FAK inhibitor, which inhibits FAK phosphorylation at the Tyr397 site in a time- and dose-dependent manner.

    IC50 & Target

    FAK[1]

    體外研究
    (In Vitro)

    Defactinib (VS-6063) inhibits FAK phosphorylation at the Tyr397 site in a time- and dose-dependent manner. RPPA data shows that Defactinib reduces levels of AKT and YB-1 in taxane-resistant cell lines. The expression of pFAK (Tyr397) is statistically significantly inhibited by Defactinib in a dose-dependent manner in all cell lines. Defactinib inhibits pFAK (Tyr397) expression within 3 hours, with a gradual return of expression by 48 hours[1].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    體內研究
    (In Vivo)

    Defactinib (VS-6063) doses of 25 mg/kg twice a day or greater statistically significantly inhibits pFAK (Tyr397) at 3 hours, with return of expression noted by 24 hours. Therefore, administration of Defactinib at 25 mg/kg twice a day is selected as the dosing schedule for subsequent therapy experiments. For therapy experiments, female nude mice bearing HeyA8 tumors in the peritoneal cavity are randomly divided into 4 groups (n=10 per group): 1) vehicle orally twice daily and phosphate-buffered saline intraperitoneally weekly (control); 2) Defactinib 25 mg/kg orally twice daily; 3) PTX intraperitoneally weekly; and 4) both VDefactinib 25 mg/kg orally twice daily and PTX intraperitoneally weekly. There is an 87.4% reduction in tumor weight by PTX monotherapy in the HeyA8 model, and combination therapy resulted in the greatest tumor weight reduction, with a 97.9% reduction (P=0.05 compared with PTX). In the SKOV3ip1 model, a 92.7% tumor weight reduction is observed in the combination group compared with PTX (P<0.001)[1].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    動物實驗:

    請根據您的 實驗動物和給藥方式 選擇適當的溶解方案。

    以下溶解方案都請先按照 In Vitro 方式配制澄清的儲備液,再依次添加助溶劑:
    ——為保證實驗結果的可靠性,澄清的儲備液可以根據儲存條件,適當保存;體內實驗的工作液,建議您現用現配,當天使用;
    以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比;如在配制過程中出現沉淀、析出現象,可以通過加熱和/或超聲的方式助溶

    • 方案 一

      請依序添加每種溶劑: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 0.67 mg/mL (1.22 mM); 澄清溶液

      此方案可獲得 ≥ 0.67 mg/mL(飽和度未知)的澄清溶液。

      1 mL 工作液為例,取 100 μL 6.7 mg/mL 的澄清 DMSO 儲備液加到 400 μL PEG300 中,混合均勻;再向上述體系中加入 50 μL Tween-80,混合均勻;然后再繼續(xù)加入 450 μL 生理鹽水 定容至 1 mL。

      生理鹽水的配制:將 0.9 g 氯化鈉,溶解于 ddH?O 并定容至 100 mL,可以得到澄清透明的生理鹽水溶液。

    Animal Administration
    [1]

    Mice[1]
    To determine the antitumor effects of Defactinib, SKOV3ip1, SKOV3-TR, HeyA8, and HeyA8-MDR cells are injected intraperitoneally. One week after tumor cell injection, mice are randomly assigned to 4 groups of 10 mice (control, PTX alone, Defactinib alone, and PTX with Defactinib); treatment is initiated at 3-4 weeks following injection. PTX at 2 mg/kg (SKOV3ip1 and SKOV3-TR) or 2.5 mg/kg (HeyA8 and HeyA8-MDR) is given intraperitoneally weekly; Defactinib at 25 mg/kg is given orally twice every day. Control mice received HBSS intraperitoneally once a week and vehicle orally twice every day. Mice are monitored daily for adverse effects of therapy and are killed on day 35 (SKOV3ip1 or SKOV3-TR), day 28 (HeyA8 or HeyA8-MDR), or when any of the mice seemed moribund. Total body weight, tumor incidence and mass, and the number of tumor nodules are recorded. Tumors are either fixed in formalin or embedded in paraffin or snap frozen in optimal cutting temperature (OCT) compound in liquid nitrogen.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
