    生物活性

    Lificiguat binds to the β subunit of soluble guanylyl cyclase(sGC) with Kd of 0.6-1.1 μM in the presence of CO.

    IC50 & Target

    Kd: 0.6-1.1 μM (sGC, in the presence of CO)[1]
    体外研究
    (In Vitro)

    Soluble guanylate cyclase (sGC) is a heterodimeric heme protein and the primary NO receptor. Lificiguat (YC-1) binds near or directly to the heme-containing domain of the beta subunit. In the absence of CO, Lificiguat (YC-1) binds with Kd=9-21 μM, depending on construct. In the presence of CO, these values decrease to 0.6-1.1 μM. Lificiguat (YC-1) greatly enhanced CO binding to heterodimeric sGC, as expected (Kd=1 μM). Lificiguat (YC-1) stimulates sGC two- to four-fold in the absence of NO but acts synergistically with CO or NO to achieve several hundred fold activation. Binding of Lificiguat(YC-1) can also overcome inhibitory phosphorylation of sGC[1]. Lificiguat (YC-1) is a soluble guanylyl cyclase (sGC) activator. HCC cell lines HepG2, BEL-7402 and HCCLM3 are incubated for 72 h with Sorafenib and/or Lificiguat (YC-1). Sorafenib or Lificiguat (YC-1) alone inhibits HCC cell proliferation in a dose-dependent manner. Moreover, combination of Sorafenib and Lificiguat (YC-1) significantly suppresses proliferation of HCC cells in a dose-dependent manner. In addition, at the ED50 doses for both Sorafenib and Lificiguat (YC-1), combination index values (CI)=0.93 in HepG2, 0.95 in BEL-7402 and 0.72 in HCCLM3 respectively, suggesting that Sorafenib and Lificiguat (YC-1) synergistically inhibit proliferation of HCC cells[2].

    体内研究
    (In Vivo)

    Lificiguat (YC-1) (30 or 60 mg/kg, i.p.) inhibits MDA-MB-468 tumor growth in a dose-dependent manner. The effect of the prodrug formulation of Lificiguat (YC-1), YC-1-S, in MDA-MB-468 tumor-bearing mice is also investigated. In vivo pharmacokinetic analysis reveal that YC-1-S is quickly converted into its active form. Mice are administered 20, 40 or 80 mg/kg YC-1-S p.o. YC-1-S also displays dose-dependent inhibition of MDA-MB468 tumor growth. Both Lificiguat (YC-1) and YC-1-S dose-dependently reduce tumor weight. Moreover, the mean body weight of mice is not affected by Lificiguat (YC-1) or YC-1-S compare with vehicle-treated groups[3]. Lificiguat (YC-1) is a potent NO-GC activator reported to improve rodent learning behavior when examined with the Morris water maze (MWM) and avoidance tests. Lificiguat (YC-1) enhances long-term potentiation (LTP) in hippocampal Schafer collateral-CA1 synapse via the NO-cGMP-PKG-dependent pathway and potentiated LTP induction in the amygdala, increases the activation of ERK, and potentiated the expression of brain-derived neurotrophic factor (BDNF) cAMP response element-binding protein (CREB) in response to fear memory test[4].

    Kinase Assay
    [1]

    CO dissociation constants are measured by titrating CO from a saturated solution into sGC protein and monitoring the appearance of the CO-bound Soret absorption band. The Ms sGC β1(1-380) and Bt sGC β1(1-197) samples are prepared in Ar-purged buffer supplemented with excess dithionite. CO binding experiments are performed in a 10 cm pathlength cuvette for Ms sGC-β1(1-380) and Ms sGC-NT21 using a Cary 50 spectrophotometer with a modified sample holder. Binding data in the presence and absence of 50 μM Lificiguat (YC-1) is plotted using a single site saturation ligand binding model in SigmaPlot[1].

    Cell Assay
    [2]

    Cell proliferation assay is measured using a Cell Counting Kit-8 (CCK-8). Briefly, cells are cultured in 96-well plates at a concentration of 3×103/well, incubated for 24 h, and treated with Sorafenib and/or Lificiguat (YC-1). After 72 h treatment, CCK-8 reagent is added to each well. The absorbance is measured at 450 nm after 2.5 h incubation at 37°C using an automated ELISA plate reader. Any synergistic effects resulting from combination of the compounds are measured using Microsoft Excel software to determine the combination index values (CI>1: antagonistic effect, CI=1: additive effect, and CT<1: synergistic effect)[2].

    Animal Administration
    [3][4]

    Mice[3]
    Fifty-eight female nu/nu mice (4 weeks-old) are used. MDA-MB-468 breast cancer cells (5×106 cells per mouse) are suspended in 0.1 mL of Matrigel solution (50% v/v Matrigel in PBS) and inoculated into the mammary fat pads of nude mice. When the tumor masses reach 100 mm3, the tumor-bearing mice are randomly divided into groups for treatments with different Lificiguat (YC-1)/YC-1-S doses. The mice are i.p. injected with YC-1 (30 or 60 mg/kg) or administered YC-1-S p.o. Tumor size and mouse body weight are measured once every 3 days, and tumor volume (mm3) is calculated using the equation: length×(width)2×0.5. At the end of the experiments, mice are killed and tumor nodules are dissected and weighed. Tumor tissues are subjected to Western blotting.
    Rats[4]
    4-month-old (200-250 g) and 24-month-old (550-600 g) male Wistar-albino rats are used. Lificiguat (YC-1) is prepared immediately prior to use and given intraperitoneally (i.p.) in a volume of 0.1 mL per 100 g body weight. All rats receives 1 mg/kg/day of Lificiguat (YC-1) for 2 weeks. DMSO is administered to 4-month-old and 24-month-old rats (n=10, for each group). Doses are selected to confirm the selected doses on locomotor activity; all results are measured.

    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.
