    RKI-1447 dihydrochloride 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.

    體外研究
    (In Vitro)

    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[1].
    RKI 1447 (0.003-10 μM) is potent at inhibiting the phosphorylation of the ROCK substrates MLC-2 and MYPT-1 in human cancer cells[1].
    RKI 1447 exhibits effective anticancer activity in colorectal carcinoma (CRC). RKI 1447 (10-320 μM; 24 hours) drastically suppresses HCT-8 and HCT-116 cell growth[2].
    RKI 1447 (20-80 μM; 24 hours) induces apoptosis in a dose-dependent manner[2].

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

    Cell Viability Assay[2]

    Cell Line: CRC cell lines HCT-8 and HCT-116 cells
    Concentration: 0, 10, 20, 40, 80, 160, 320 μM
    Incubation Time: 24 hours
    Result: HCT-8 and HCT-116 viability was drastically decreased in a dose-dependent manner.

    Apoptosis Analysis[2]

    Cell Line: CRC cell lines HCT-8 and HCT-116 cells
    Concentration: 0, 20, 40, 80 μM
    Incubation Time: 24 hours
    Result: Treatment promoted apoptosis.

    Western Blot Analysis[1]

    Cell Line: MDA-MB-231 human breast cancer cells
    Concentration: 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3 ,10 μM
    Incubation Time:
    Result: Decreased the levels of P-MLC-2, but not total MLC-2, in a concentration-dependent manner with significant effects starting at 100 nM.
    體內(nèi)研究
    (In Vivo)

    RKI 1447 (200 mg/kg; i.p. daily for 14 days) inhibits mammary tumor growth in vivo[1].
    RKI 1447 (100 mg/kg; i.p.; once every 3 days; for 14 days) exerts antitumor activity on CRC in vivo. RKI 1447 does not exert physiological toxicity on the mice[2].

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

    Animal Model: MMTV/neu transgenic mice [FVB/N-Tg (MMTVneu) 202 Mul/J][1]
    Dosage: 200 mg/kg
    Administration: Treated i.p. daily for 14 days
    Result: Tumors from mice treated with vehicle increased in size with an average percent change in tumor volume of 68.3%. In contrast, tumors from mice treated with the RKI-1447 increased in size with an average percent change in tumor volume of only 8.8%. Thus, RKI-1447 inhibited mammary tumor growth by 87%.
    Animal Model: 5-week-old Male BALB/C nude mice[2]
    Dosage: 100 mg/kg
    Administration: Intraperitoneally injected; once every 3 days; for 14 days
    Result: Efficiently blocked CRC tumor growth in vivo.

    • 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.
