2 mtt assay of embodiment presses down the hepatic stellate cells experiment of activation in vitro
The present embodiment carries out the hepatic stellate cells reality that mtt assay presses down activation in vitro for Lignanoids compounds of the present invention It tests.
Experimental material: human liver microsome proteins strain LX-2, cultured rat hepatic stellate cells strain T-6
Test medicine: it is 100 μM, 20 μM, 4 μM, 0.8 μM and 0.16 μM that 15 compounds, which prepare final concentration gradient,.
Positive control: it is 100 μM, 20 μM, 4 μM, 0.8 μM and 0.16 μM that saikoside d, which prepares final concentration gradient,.
By taking human liver microsome proteins strain LX-2 as an example, 15 compounds are measured to hepatic stellate cells after activation using mtt assay Inhibiting effect.
(1) strain of LX-2 human liver microsome proteins counts, and cell is made 5 × 104The cell suspension of a/mL.
(2) cell suspension is taken, is inoculated in 96 porocyte culture plates, every 200 μ L of hole.37 DEG C, 5%CO2Saturated humidity It is cultivated in incubator for 24 hours, it is adherent to cell.
(3) every hole sequentially add TGF-β 1 to final concentration of 10ng/mL be incubated for for 24 hours.
(3) thereafter, test medicine is added in 96 orifice plates, every group is all provided with 5 multiple holes.Solvent control group and bavin are set up simultaneously Hu saponin(e d positive controls.37 DEG C, 5%CO248h is cultivated in the incubator of saturated humidity.
(4) 10 μ L MTT solution (5mg/mL is dissolved in PBS, 0.22 μm of film filtering), culture is added in every culture hole thereafter Stationary culture 4h again in case.
(5) supernatant is sucked out, 150 μ L dimethyl sulfoxides (DMSO) are added in every hole, and micro oscillator vibrates 5min.
(6) finally with microplate reader at 490nm wavelength, each hole light absorption value is measured.Statistical data simultaneously carries out data analysis.
T-6 cultured rat hepatic stellate cells are also adopted to be tested through row with the aforedescribed process.Compound is starlike to the people liver after activation thin The IC of born of the same parents' strain LX-2 and mouse hepatic stellate cells T-650Value see the table below 2.
Table 2
By table 2, statistics indicate that, the compound in the present invention has the significant proliferation function for inhibiting activation hepatic stellate cells, Lower IC50 value, i.e., stronger inhibition activation are shown in human liver microsome proteins strain LX-2, cultured rat hepatic stellate cells strain T-6 The effect of hepatic stellate cell proliferation.And the overwhelming majority has identical as positive control saikoside d or higher inhibition thin The effect of born of the same parents' proliferation, shows the effect of stronger anti-hepatic stellate cell proliferation in vitro experiment, and it is fine to can be used as new anti-liver The development and utilization of chemical drug object are tieed up, especially compound 1d and 1e is preferred.

The anti-hepatic fibrosis activity of 3 molecular level of embodiment is tested
The present embodiment carries out the anti-hepatic fibrosis activity experiment of molecular level for 15 compounds of the present invention respectively.
MMP2 activity Elisa kit, MMP9 activity Elisa kit, 1 activity Elisa kit of TGF-β and MMP2, MMP9,1 protein standard liquid of TGF-β are provided by Beijing Dong Ge Biotechnology Co., Ltd.
Five concentration gradients are respectively configured in 15 compounds, and each concentration gradient differs 10 times.Respectively by various concentration 15 compounds mix respectively from different protein standard liquid, and the activity of albumen in each sample is detected using Elisa kit.
The process for using of kit is as follows:
(1) prepare: taking out kit from refrigerator, room temperature rewarming balances 30min;
(2) match liquid: 20 times of concentrated cleaning solutions being diluted to former cleaning solution again with distilled water;
(3) sample to be tested is added: taking sufficient amount of enzyme mark coating plate, is fixed on frame, sample to be tested is respectively set Hole and blank control wells record each hole site, and 10 μ L of sample to be tested, then plus 40 μ L (i.e. Sample Dilution 5 of Sample dilution is first added Times);Blank control wells are not added;
(4) incubate: insulating box incubates 30min;
(5) board-washing: discarding liquid, pat dry on blotting paper, and cleaning solution is filled it up in every hole, stands 1min, gets rid of cleaning solution, absorbs water It pats dry on paper, so repeats board-washing 4 times;
(6) enzyme mark working solution: 50 μ L of enzyme mark working solution is added in every hole, and blank control wells are not added;
(7) incubate: 37 DEG C of insulating boxs incubate 30min;
(8) board-washing: discarding liquid, pat dry on blotting paper, and cleaning solution is filled it up in every hole, stands 1min, gets rid of cleaning solution, absorbs water It pats dry on paper, so repeats board-washing 4 times;
(9) develop the color: 50 μ L of color developing agent A liquid is first added in every hole, adds 50 μ L of color developing agent B liquid, and plate vortex mixer mixes 30s, 37 DEG C are protected from light colour developing 15min;
(10) it terminates: taking out ELISA Plate, every hole adds 50 μ L of terminate liquid, terminates reaction;
(11) it measures: being returned to zero with blank well, after termination in 15min, with the light absorption value in each hole of 450nm wavelength measurement.
Experimental data is as shown in table 5.
Table 5
