Experimental test examples:
the test principle is as follows: the sulfonyl rhodamine colorimetry is mainly used for detecting the proliferation condition of cells. SRB is a pink anionic dye, readily soluble in water, and specifically binds to basic amino acids of intracellular constituent proteins under acidic conditions; the absorbance peak is generated at the wavelength of 540nm, and the absorbance value is linearly and positively correlated with the cell quantity, so that the method can be used for quantitative detection of the cell quantity.
The test method comprises the following steps:
Sample preparation: dissolving compound in DMSO, ultrasonically dissolving, and storing the obtained medicinal solution at-20deg.C at concentration of 100 mM/L;
The log phase cells were collected, inoculated onto 96 well cell culture plates, and the drug solutions to be tested were added at different concentrations. After 72 hours of incubation, 10% trichloroacetic acid was added, incubated at 4℃for 1 hour, washed 5 times with tap water and air-dried, and surviving cells were stained with 0.4% (w/v) sulforhodamine B for 20min at room temperature, washed 5 times with 1% acetic acid, dissolved in 10mM Tris solution, and absorbance of each well was measured at 540nm in an ELISA.
The test data calculation method comprises the following steps:
Inhibition (%) = (average value of no drug cell control well a value-average value of drug administration well a value)/average value of no drug cell control well a value x 100%.
Based on the experimental results, data on all IC50 values, which are quite close to the normal method, were calculated according to the dot-skew method principle.
The basic formula:
1.IC50:IC50＝Log-1[Xm-i×(∑p–0.5)+i/4×(1-Pm-Pn)]
2. LD50 with 0% and 100% mortality:
IC50＝Log-1[Xm-i×(∑p–0.5)]
wherein Xm is the dose logarithmic value of the group with highest mortality rate Pm, i is the group distance, pm is the highest mortality rate, pn is the lowest mortality rate, and n is the number of animals in each group.
The activity results are shown in the following table:
From the above anti-tumor activity results, it can be seen that the compounds 3-6, 3-7, 3-17, 3-21, 3-22, 3-34, 3-38 of the present invention have significant cancer cell inhibitory activity, and the half-inhibitory concentrations of the compounds 3-7, 3-17 on human lung cancer cells are 1.2 and 2.4. Mu.M, respectively.
