The target verivate is for the activity data of the provide protection of the PC12 cell injury of glutamate induction among the embodiment.
This mensuration adopts tetrazolium bromide (MTT) colorimetric test method by routine, promptly uses rat suprarenal gland pheochromocyte tumor cell strain (PC12 cell), to contain the DMEM substratum of 10% calf serum, at 37 ℃ of 5%CO
2Cultivate in the incubator.Passage cell is observed passage cell under inverted microscope every other day.When the even adherent growth of cell, grow at 80% to 90% o'clock, behind tryptic digestion 1~2min of 0.25%; The high sugared DMEM substratum adjustment cell density that use contains 10% calf serum is 1 * 105/mL; Be seeded in 96 (24) well culture plates, every hole 100 (400) μ L are in 37 ℃ of 5%CO
2Cultivate 24h under the condition.Change with the substratum that contains L-glutamic acid and different pharmaceutical concentration to cell again behind the 24h and continue to cultivate 24h.Cultivate each hole and be divided into 7 groups: comprise that normal group, L-glutamic acid damage model group, Edaravone group and L-glutamic acid add four different concns drug group, every group is repeated 6 holes.Add 5mg/mL MTT 10 μ L/ holes after 24 hours in administration, hatch 4h for 37 ℃, stop cultivating, the careful suction abandoned the liquid in the culture plate, and every hole adds 150 μ L DMSO, and 37 ℃ of vibration 10min fully dissolve hyacinthine formazan crystallization.On ELIASA, measure each hole OD value with the 490nm wavelength.The inhibiting rate of the PC12 cell injury that L-glutamic acid is caused according to the computes medicine:
Inhibiting rate=(OD administration group-OD model group)/(OD control group-OD model group) * 100%.
With the drug level logarithmic value inhibiting rate is done linear regression, get straight-line equation, therefrom obtain the half-inhibition concentration (IC of medicine the PC12 cell injury
50).
Reagent source:
MTT: tetrazolium bromide (Thiazolyl Blue Tetrazolun Bromide), the import of Sigma company;
The PC12 cell: rat suprarenal gland pheochromocyte oncocyte, Shanghai Inst. of Cytobiology, Chinese Academy of Sciences provides;
Above-mentioned experiment shows: part verivate of the present invention has protection active for the PC12 cell injury of glutamate induction, and wherein verivate WB-07, WB-08, WB-13, WB-17 and WB-18 are suitable with the positive control Edaravone.
