The biologic activity of compound is measured in the growth-inhibiting effect of the male hormone dependency Human Prostate Cancer Cells LNCaP that utilization of the present invention is induced male sex hormone and the androgen independence Human Prostate Cancer Cells CWR22RV1 cell of hormone resistance.
The compound biological activity determination
We check above-claimed cpd to the bioactive influence of androgen receptor with prostate cancer cell, and the cell of our usefulness has two kinds: LNCaP and CWR22RV1.The LNCaP cell is male hormone dependency Human Prostate Cancer Cells, and CWR22RV1 is the androgen independence Human Prostate Cancer Cells of hormone resistance.These two kinds of cells are all expressed androgen receptor, and male sex hormone can induce the genetic expression of prostate specific antigen (PSA), and can induce the growth of this cell.The growth-inhibiting effect of cell, the biologic activity of mensuration compound.
Specific antigens is an important indicator of prostate cancer, and its expression is regulated and control by androgen receptor, reflects the physiologically active of androgen receptor because of the expression level of a little prostate specific antigen.In order to check above-claimed cpd to the inhibition ability of androgen receptor function, we effectively induce the expression of prostate specific antigen with male hormone DHT, measure the inhibition ability that prostate specific antigen that compound induces DHT is expressed then.We use RPMI-1640 substratum (100 units/ml penicillin that contain 10% foetal calf serum, 100mg/L Streptomycin sulphate and 10% foetal calf serum) cultivation prostate cancer cell LNCaP and CWR22RV1, before test compounds suppresses the androgen receptor ability, my these two kinds of cell cultures of people are cultivated in charcoal adsorbs to fall the RPMI-1640 substratum of androgenic foetal calf serum (Charcoal-stripped FBS) in containing 10%, after two days, we add the DHT and 0.25 of androgenous 11 0nM in nutrient solution, 0.5,1,2,5,10 μ M, the test compounds of concentration tonsure is cultivated after four days, we are secreted into the concentration of the prostate specific antigen of nutrient solution with the measurement of integrated enzyme reaction reagent, calculate 50 percent the inhibition ability (IC that test compounds suppresses prostate specific antigen then
50).Table 1 is listed tested compound to 50 percent inhibition ability (IC of the prostate specific antigen of the androgen independence Human Prostate Cancer Cells CWR22RV1 of androgen-dependent Human Prostate Cancer Cells LNCaP and hormone resistance
50).
Table 1, tested compound are to 50 percent inhibition ability (IC of the prostate specific antigen of the androgen independence Human Prostate Cancer Cells CWR22RV1 of androgen-dependent Human Prostate Cancer Cells LNCaP and hormone resistance
50).
We have also checked the growth-inhibiting effect of the androgen independence Human Prostate Cancer Cells CWR22RV1 cell of male hormone dependency Human Prostate Cancer Cells LNCaP that some compounds induce male sex hormone and hormone resistance, similar with above method, we LNCaP cell and CWR22RV1 cell be placed on contain 10% in charcoal adsorbs to fall the RPMI-1640 substratum of androgenic foetal calf serum, cultivate 2 days after, the test compounds that in substratum, adds male hormone DHT and finite concentration gradient, make its ultimate density reach DHT and the 1 μ M of 10nM, 2.5 μ M, the test compounds of 5 μ M concentration tonsures, cultivate after six days, we calculate the total cellular score of growth, accompanying drawing shows it is that to deduct the total cellular score of growing when not adding DHT with the cell growth sum that 10nM DHT induces be 100% growth, the compound of different concns suppresses ability to the allometry of the androgen independence human prostata cancer CWR22RV1 cell of male hormone dependency Human Prostate Cancer Cells LNCaP and hormone resistance, and three kinds of chemical structures are strong to the growth-inhibiting energy widely used bicalutamide of force rate (Bicalutamide) of LNCaP and CWR22RV1.
The allometry of the male hormone dependency Human Prostate Cancer Cells LNCaP (Fig. 1) that accompanying drawing, three kinds of compounds are induced male sex hormone and the androgen independence Human Prostate Cancer Cells CWR22RV1 (Fig. 2) of hormone resistance suppresses ability.
LNCaP and CWR22RV1 cell cultures in contain 10% through charcoal adsorb to fall cultivate 2 days in the RPMI-1640 substratum of androgenic foetal calf serum after, the test compounds that in substratum, adds male hormone DHT and finite concentration gradient, making its ultimate density is DHT and the 1 μ M of 10nM, 2.5 μ M, the test compounds of 5 μ M concentration tonsures, cultivate after six days, we calculate the total cellular score of growth, and accompanying drawing shows it is that to deduct the total cellular score of growing when not adding DHT with the cell growth sum that 10nM DHT induces be 100% to come the allometry of computerized compound to suppress ability.
