    RKI-1447 purchased from MCE. Usage Cited in: Med Sci Monit. 2020 Feb 6;26:e919220.  [Abstract]

    The effects of RKI-1447 on glucose tolerance and insulin resistance in a mouse model of nonalcoholic fatty liver disease (NAFLD) induced by a high-fat diet. The expression of the insulin receptor substrate-1 (IRS1) are shown. The mice were fed with a high-fat diet for 12 weeks. From the ninth week, the mice were treated orally with the ROCK inhibitor RKI-1447 (2 mg/kg to 8 mg/kg) twice weekly for three weeks.

    体外研究
    (In Vitro)

    RKI-1447 is a Type I kinase inhibitor that binds the ATP binding site through interactions with the hinge region and the DFG motif. RKI-1447 suppresses phosphorylation of the ROCK substrates mLC-2 and MYPT-1 in human cancer cells, but has no effect on the phosphorylation levels of the AKT, MEK and S6 kinase at concentrations as high as 10 μM. RKI-1447 is also highly selective at inhibiting ROCK-mediated cytoskeleton re-organization. RKI-1447 inhibits migration, invasion and anchorage-independent tumor growth of breast cancer cells[1].

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

    (In Vivo)

    RKI-1447 is highly effective at inhibiting the outgrowth of mammary tumors in a transgenic mouse model. RKI-1447 inhibits mammary tumor growth by 87% and on average the mammary tumors from RKI-1447 treated mice are 7.7 fold smaller compared to those tumors from mice treated with the vehicle control[1].

    动物实验：

    请根据您的 实验动物和给药方式 选择适当的溶解方案。

    以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：
    ——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；
    以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

    • 方案 一

      请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (7.66 mM); 澄清溶液

      此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

      以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入 50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。

      生理盐水的配制：将 0.9 g 氯化钠，溶解于 ddH₂O 并定容至 100 mL，可以得到澄清透明的生理盐水溶液。

    Kinase Assay
    [1]

    Compounds are tested on three separate days with 8 point dilutions performed in duplicate to determine average IC50 values. The assay conditions are optimized to 15 µL of kinase reaction volume with 5 ng of enzyme in 50 mM HEPES (pH 7.5), 10 mM MgCl2, 1 mM EGTA, and 0.01% Brij-35. The reaction is incubated for 1 h at room temperature in the presence of 1.5 µM of peptide substrate with 12.5 µM of ATP (for ROCK1) or 2 µM of substrate with 50 µM of ATP (for ROCK2). The reaction is then stopped and the ratio of phosphorylated to unphosphorylated peptides is determined by selective cleavage of only the unphosphorylated peptide. The ratio of the signals at 445 nm and 520 nm is measured. IC50 values are determined using fitted curves with GraphPad Prism 5 software[1].

    Cell Assay
    [1]

    NIH 3T3 cells are plated at 8000 cells/well in 8-chamber slides in serum free media for 24 hours, and treated with vehicle, 1 μM RKI-1447 or 1 μM RKI-1313 for 1 hour. The cells are then stimulated with complete media, 10 μM LPA, 200 ng/mL bradykinin or 30 ng/mL PDGF for 30 mins. After stimulation, the cells are fixed in 4% paraformaldehyde and stained with Texas-Red Phalloidin. Mounting medium containing DAPI is then added and at least 100 cells per well are observed[1].

    Animal Administration
    [1]

    Mice: MMTV/neu transgenic mice are treated i.p. daily for 14 days with either Vehicle [20%-2-hydroxypropyl-beta-cyclodextrin (HPCD)] or 200 mpk RKI-1447 dissolved in freshly prepared HPCD. The percent change in volume is calculated on the basis of the tumor volume on the last day of treatment (Vf) relative to that on the day of initiation of treatment (V0). The average percent change in tumor volume is then calculated for each treatment group[1].

    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.
