Enzyme II) relevant dehydrogenase, succinate dehydrogenase can make the thiazolyl blue MTT (3- (4,5)-dimethylthiazole -2- of exogenous yellow
Base) -2,5- diphenyl bromination tetrazolium) it is reduced to bluish violet crystallization first a ceremonial jade-ladle, used in libation (Formazan) of water-insoluble and is deposited on cell
In, this enzyme disappears in dead cell, and MTT is not reduced.With dimethyl sulfoxide (DMSO) dissolve after first a ceremonial jade-ladle, used in libation can with microplate reader in 570nm,
Absorbance is detected at 630nm, OD value is directly proportional to viable count.
Cell strain used are as follows: BGC-823 (gastric carcinoma cells), Bel (human liver cancer cell), HCT-8 (human colon cancer cell),
A2780 (Proliferation of Human Ovarian Cell) and A549 (human lung carcinoma cell) (being purchased from ATCC company).
Test method: mtt assay: taking logarithmic growth cell, and sufficiently piping and druming is diluted to after counting at single cell suspension after digestion
1×104Cell/mL is inoculated in 96 well culture plates, and 100 μ L cell suspensions are added in every hole, is placed in 37 DEG C/5%CO2Saturated humidity
After cultivating 24 hours in incubator, original fluid is discarded.6 concentration gradients of each sample design, are then added in test hole
100 μ L contain the compound of the above-mentioned preparation of each concentration gradient and the culture medium of taxol (positive control), and each concentration is flat
6 hole of row；Isometric solvent is added in control group.96 well culture plates are placed in 37 DEG C/5%CO272 are cultivated in saturated humidity incubator
After hour, the serum free medium 20 μ L of the MTT containing 5mg/mL of fresh configuration is added in every hole, continues culture 4 hours at 37 DEG C
Afterwards, supernatant is removed.150 μ LDMSO dissolution Formazan precipitating is added in every hole, and setting to shake 5 minutes on micro oscillator fills it
Divide dissolution.570nm is measured in microplate reader, the absorbance at 630nm can reflect living cells quantity.It is calculated by SPSS software
Inhibition concentration (the IC of drug50) value.
