5Individual cell suspension is inoculated in 96 orifice plates, and every hole 150 μ L pass into 5%CO in 37 ℃
2With cultivate 18～24h in the incubator of 95% air, attract to discard culture fluid, be divided into Normal group, anoxia matched group and anoxia administration group, each is organized each sample and all establishes three holes.Normal group and the every hole of anoxia matched group add each the 150 μ L of fresh DMEM culture medium that contain each 100 μ g/mL of 10% newborn calf serum, penicillin and streptomycin, and the every hole of anoxia administration group adds each 150 μ L of sample solution.Matched group and administration group are cultivated 1h in incubator, anoxia matched group and anoxia administration group are with 31.25 μ M CoCl
2Processing 2h causes the anoxia-induced apoptosis to cell, then the normal 24h that cultivates in incubator.After cultivating end, every hole adds each 15 μ L of MTT solution (with the PBS liquid preparation of 0.01M) of 5mg/mL, mixing, hatch 4h for 37 ℃, the turnover panel method discards culture fluid in the hole, every hole adds each 150 μ L of DMSO, and vibration 10min fully dissolves MTT purple product, measures every hole in the OD at 490nm place value with microplate reader.Data are got and are respectively organized the cell survival rate that the OD meansigma methods is calculated as follows anoxia matched group and anoxia administration group take Normal group as 100%: cell survival rate (%)=anoxia matched group or anoxia administration group OD meansigma methods/Normal group OD meansigma methods * 100%.Get the independent experiment data 8 times, calculate corresponding cell survival rate (%), and use the Student-t method of inspection, the significant difference of cell survival rate between two groups of statistical test anoxia matched group and anoxia administration groups.
Experimental result sees table 1 for details.Test result shows shown in the table 1, and the compounds of this invention I～VII anoxia-induced apoptosis to the PC12 cell in trial concentration range has remarkable protective effect.
Table 1. Compound I～VII is to the protective effect of PC12 cell hypoxia damage
*Asterisk shows with corresponding anoxia matched group has compared significant difference, P＜0.01
Conclusion:
Compound I of the present invention, II, III, IV, V, VI, VII have significant protective effect to the anoxia-induced apoptosis of PC12 cell.Therefore, above-claimed cpd of the present invention can be used as the anti-hypoxia active component for the preparation of functional foods such as anti-anoxic medicine and health products of anti-anoxia.
