Description
Technical field
The present invention relates to medicinal chemistry art, in particular to aromatic heterocycle sulfamide compound and preparation method thereof and purposes.
Background technology
Mammary cancer (mammarycarcinoma) is the modal a kind of malignant tumour of the mankind is also one of women's major malignant tumor.The malignant tumour overwhelming majority system of breast comes from the epithelium (breast cancer) of mammary gland, and the various non-epithelium (various sarcoma) that minority can be derived from breast occasionally can see blended sarcocarcinoma.The sickness rate of mammary cancer rises year by year, and crowd's morbidity is 23,/10 ten thousand; Account for 7 ~ 10% of the various malignant tumour of women's whole body.
Univ Michigan-Ann Arbor USA researchist MaxS.Wicha in 2010 etc. identify the new effect of a kind of acceptor, CXCR1, are positioned at mammary cancer cancer stem cell surface, under tissue damaged or the stimulation of inflammatory reaction, have the ability exciting cancer stem cell to grow.CXCR1 is the acceptor of interleukin 8 (IL-8), and IL-8 is everlasting in chronic inflammatory diseases and tissue-damaging process and produces.After patient with breast cancer accepts chemotherapy, dead cancer cell can produce IL-8, and this will promote the self-replacation of cancer stem cell.If add relative medicine and block CXCR1 in Breast Cancer Patients Treated process, will effectively help to kill breast carcinoma stem cell.
Reparixin (N-[(R)-2-(4-isobutylphenyl) propionyl]-methanesulfonamide) is a kind of benzyl propionate derivant, interleukin 8 albumen can be suppressed to be combined with acceptor CXCR1, thus block breast carcinoma stem cell FAK/AKT/ beta-catenin path, accurately hit cancer stem cell.Researchist with the experimental mouse of et al. Ke breast cancer cell for object carries out studying rear discovery, accept simultaneously chemotherapy and repertaxin treatment experimental mouse body in cancer stem cell quantity far below the experimental mouse only accepting chemotherapy, further, the probability adding the mouse generation Nasopharyngeal neoplasms of repertaxin treatment also reduces.Interim for suppressing the medicine Reparixin (Repertaxin) of organ naltrindole can kill breast carcinoma stem cell and stop the diffusion of tumour in clinical trial 2 at present.
Up to the present, do not have a kind of medicine fundamentally to suppress or to eliminate breast carcinoma stem cell, reach the effect of thoroughly curing.Therefore, urgently find a kind of better efficacy, toxic side effect is little, the medicine of the treatment mammary cancer of high specificity.

pharmacologically active part
The present invention adopts MTT colorimetric method for determining cytoactive.
MTT colorimetry is a kind of method detecting cell survival and growth.Its Cleaning Principle is that the succinodehydrogenase in viable cell plastosome can make exogenous MTT be reduced to water-insoluble bluish voilet crystallization first a ceremonial jade-ladle, used in libation (Formazan) and be deposited in cell, and dead cell is without this function.First a ceremonial jade-ladle, used in libation in dimethyl sulfoxide (DMSO) (DMSO) energy dissolved cell, measures its absorbance value with enzyme-linked immunosorbent assay instrument at 490nm wavelength place, can indirectly reflect viable cell quantity.Within the scope of certain cell count, the amount that the crystallization of first a ceremonial jade-ladle, used in libation is formed is directly proportional to cell count.
MTT full name is 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide, chemistry 3-(4 by name, 5-dimethylthiazole-2)-2,5-diphenyltetrazolium bromide bromine salt, commodity are called tetrazolium bromide, are a kind of dyestuffs of yellow color.
MTT powder is bought in Sigma company, and during use, phosphoric acid buffer (PBS) is mixed with the solution that concentration is 5mg/ml, with 0.22 μm of membrane filtration to remove the bacterium in solution, then keeps in Dark Place at 4 DEG C.
MTT colorimetric method for determining cytoactive comprises several step below:
Step 1): dosing spreads 96 orifice plates with SUM-159, HCC-1954 and MCF-7 cell (purchased from gold amethyst bio tech ltd, Beijing) noon before that day.Collect SUM-159, HCC-1954 and MCF-7 cell of logarithmic phase, after viable count, adjust cell concn to 2.5 × 10
4cells/mL.Inoculating cell in 96 orifice plates, every hole adds 100 μ L cell suspension bed boards, and final cell to be measured is 2500cells/ hole.Surrounding marginal pore not inoculating cell, only add 100 μ L cell culture mediums (cell culture medium used in this experiment is modified form RPMI-1640 (Hyclone) basic medium, adds the foetal calf serum (Hyclone) of 10%).5%CO
2, 37 DEG C of overnight incubation, to make cell fully adherent.
Step 2): dosing in morning next day.First dilute medicine, prepare corresponding drug concentration gradient.Add the medicine of the corresponding concentration of 100 μ L in the cell of 96 orifice plates completed to the day before yesterday, be provided with 8 concentration gradients in this experiment, system Chinese traditional medicine final concentration gradient is: 30 μMs, 27 μMs, 24 μMs, 21 μMs, 18 μMs, 15 μMs, 12 μMs, 9 μMs.Each concentration arranges 5 repetitions.The hole simultaneously arranging not dosing only inoculating cell is control group, and control group not dosing, adds the cell culture medium of 100 μ L; The hole that non-inoculating cell only adds substratum is set and is set to blank well, also add 100 μ L cell culture mediums.5%CO
2, 37 DEG C of incubators hatch X (X=24,48,72,96) hour.
Step 3): after X hour, every hole adds 20 μ LMTT solution (5mg/ml, MTT) again, continues cultivation 4 hours.If medicine and MTT can react, can first centrifugal after discard nutrient solution, carefully with PBS rinse 2-3 all over after, then add the nutrient solution containing MTT.
Step 4): stop after 4 hours cultivating, carefully suck liquid in hole.Every hole adds 150 μ L dimethyl sulfoxide (DMSO), and 37 DEG C of incubators hatch 10 minutes.Enzyme-linked immunosorbent assay instrument MULTISKANFC (Thermoscientific) is adopted to measure the light absorption value in each hole, 490nm place, using blank well as zeroing hole during measurement.
Step 5): processing data.First following formulae discovery inhibiting rate is adopted:
Inhibiting rate=1-dosing group OD value/control group OD value
Then with LogC (drug level logarithm) for X-coordinate, inhibiting rate is ordinate zou, carry out probit weighted regression method (Bliss method) with data processing software SPSS software (IBM Corporation) and carry out data processing, mapping, obtains IC
50value.
According to above-mentioned testing method, record embodiment 1-3 compound at 72 hours suppression IC to SUM-159, HCC-1954 and MCF-7 cell
50value is respectively
| SUM-159 | HCC-1954 | MCF-7 | |
| Embodiment 1 | 17.677μM | 16.654μM | 24.235μM |
| Embodiment 2 | 14.621μM | 14.654μM | 24.231μM |
| Embodiment 3 | 11.612μM | 14.213μM | 24.237μM |
According to foregoing, the survival and growth that the compounds of this invention effectively can suppress SUM159, HCC-1954 cell can be understood, slightly poor to the survival and growth restraining effect of MCF-7 cell.The compounds of this invention may be used for prevention or treatment mammary cancer, is expected to substitute the Reparixin easily producing resistance.
In order to clear and understandable object, explanation and embodiment describe in detail foregoing invention by way of example.Can carry out changing and revising in the scope of subsidiary claim, this be clearly to one skilled in the art.Therefore, the specification sheets being appreciated that above be intended to for illustration of instead of for restriction.Therefore, scope of the present invention should not determined with reference to above-mentioned specification sheets, and should determine with reference to the determined four corner of doctrine of equivalents that claims and these claims are enjoyed below.
