Description

One class 4-arylthio quinazoline derivant and preparation method and medicinal use
Technical field
The present invention relates to treat novel 4-arylthio quinazoline derivant and its preparation method and the purposes in preparation treatment acute myelocytic leukemia pharmaceutical composition of a class of acute myelocytic leukemia.
Background technology
Acute myelocytic leukemia (AML) is that hemopoietic stem cell is cloned a kind of malignant neoplastic disease that hyperplasia causes unusually, is modal type in adult's acute leukemia; Its sickness rate height, according to statistics, the annual morbidity of China AML is 1.62/100000, also has the trend that rises year by year in recent years.And show according to the recent statistics of national cancer institute, the overall sickness rate of 2001～2005 years U.S. AML is 3.6/100000, mortality ratio is 2.8/100000, and the meta age of onset is 67 years old, and over-65s patient sickness rate is 15.3/100000-18.1/100000.
Chemotherapy is the main treatment means of AML, and chemotherapeutics commonly used comprises anthracycline drug, and for example daunorubicin, and nucleoside analog draws as fluorine to reach shore, Clofarabine, Sapacitabine and Troxacytabine etc.Single medicine is used anthracene nucleus medicament treatment AML, and complete remission rate has only 30%～50%, as the associating cytosine arabinoside, can improve complete remission rate to a certain extent.But refractory, recurrence, old AML are still the difficult point of current clinical treatment.Exception, traditional chemotherapeutics target is poor, toxicity is big.Therefore, the specific molecular target chemotherapy medicine is the developing direction of following treatment AML medicine.
FLT3 (Fms-like tyrosine kinase, the Tyrosylprotein kinase 3 of FMS sample) is a kind of receptor tyrosine kinase, and it is playing an important role aspect the propagation of hemopoietic stem cell and the differentiation.Molecular biology research in recent years finds that among about 1/3rd the acute myelocytic leukemia patient, FLT3 sudden change or high expression level appear in its hemopoietic stem cell.Many studies show that has the AML patient that FLT3 suddenlys change, easily recurrence and poor prognosis.At present, as the critical treatment target spot of treatment AML, its specific inhibitor is considered to the molecular targeted agents of the most promising current treatment AML to FLT3.
Summary of the invention
The contriver has very strong FLT3 and suppresses active through discovering 4-arylthio quinazoline derivant, and its structural formula is as follows:
Figure G2009102650624D00021
In the formula, R 1Be ethylamino-or the Propylamino that methyl, methoxy ethyl, N replace, R 2Be methyl, methoxy ethyl.X 1=X 2During=CH, R 3Be hydrogen; X 1=N, X 2During=CH, R 3Be hydrogen, methyl or 4-CH 3-5-CH 2CONHR 4(R 4For replacing or unsubstituted phenyl or benzyl); X 1=X 2During=N, R 3Be hydrogen, 5-NHCONHR 4(R 4For replacing or unsubstituted phenyl).
General reactions steps is as follows:
Figure G2009102650624D00022
In the formula, R 1Be ethylamino-or the Propylamino that methyl, methoxy ethyl, N replace, R 2Be methyl, methoxy ethyl.X 1=X 2During=CH, R 3Be hydrogen; X 1=N, X 2During=CH, R 3Be hydrogen, methyl or 4-CH 3-5-CH 2CONHR 4(R 4For replacing or unsubstituted phenyl or benzyl); X 1=X 2During=N, R 3Be hydrogen, 5-NHCONHR 4(R 4For replacing or unsubstituted phenyl).
And the contriver further finds compound 6 under study for action, 7-dimethoxy-4-(thiazol-2-ylthio) quinazoline (1), and this compound has very strong restraining effect, IC to the FLT3 kinases 50(half-inhibition concentration) is 7nM, and leukemia cell line MV-4-11 and RS-4-11 that FLT3 is suddenlyd change have the obvious suppression effect.The relative molecular mass of this compound is 305.38, is white powder, and is water-soluble relatively poor, dissolves in dimethyl sulfoxide (DMSO) (DMSO) and ethanol equal solvent.Its structural formula is as follows:
Figure G2009102650624D00031
Its chemistry is by name: C 13H 11N 3O 2S 2, English name: 6,7-dimethoxy-4-(thiazol-2-yl thio) quinazoline, Chinese named: 6,7-dimethoxy-4 '-(thiazole-2-sulfenyl) quinazoline.
The preparation method of compound 1 is:
Figure G2009102650624D00032
This preparation method's advantage is: reactions steps is brief, and desired raw material reagent is cheap and easy to get, does not need column chromatography purification, and whole process only needs 1 recrystallization, can obtain target product with high purity.
Also there is not medicinal use report at present about the derivative of this compound and other 4-arylthio quinazoline.
Second technical problem to be solved by this invention provides a kind of anti-tumor small molecular targeted drug.The contriver has the kinase whose activity of the FLT3 of inhibition through discovering 4-arylthio quinazoline derivant, particularly 6,7-dimethoxy-4-(thiazol-2-ylthio) quinazoline (1) can be used for preparation treatment acute myelocytic leukemia small molecules targeted drug.
The anti-tumor small molecular targeted drug is to be that main active ingredient is added pharmaceutically acceptable complementary composition and is prepared from the 4-arylthio quinazoline derivant shown in the formula I.
Beneficial effect of the present invention is, has creatively proved that by experiment in vivo and vitro 4-arylthio quinazoline derivant has favorable anti-tumor effect, can be used to prepare antineoplastic pharmaceutical compositions.For the antitumor drug preparation field provides a kind of new selection, have good market outlook.

1.2 clone and cultivation
Used human hepatoma cell strain (HepG2), Human Prostate Cancer Cells strain (PC-3), human lung carcinoma cell line (A549), human colon cancer cell strain (HCT-116), people's chronic myelogenous leukemia cell strain (K562), human breast cancer cell strain (MCF-7), person monocytic cell's leukemia cell line (Raji), people's malignant melanoma cell strain (A375), the people's acute myeloid leukaemia cell strain (MV4-11) of this experiment all purchased the ATCC company in the U.S., preserved by this laboratory.
Human hepatoma cell strain (HepG2), Human Prostate Cancer Cells strain (PC-3), human colon cancer cell strain (HCT-116) and human breast cancer cell strain (MCF-7) are with containing the DMEM perfect medium of 10% foetal calf serum, 100U/ml penicillin, 100 μ g/ml Streptomycin sulphates at 5%CO 2, cultivate under 37 ℃ of conditions.Human lung carcinoma cell line (A549), people's chronic myelogenous leukemia cell strain (K562), person monocytic cell's leukemia cell line (Raji) and people's malignant melanoma cell strain (A375) are with containing the RPMI-1640 perfect medium of 10% foetal calf serum, 100U/ml penicillin, 100 μ g/ml Streptomycin sulphates at 5%CO 2, under 37 ℃ of conditions.People's acute myeloid leukaemia cell strain (MV4-11) (annotate: MV4-11 is the FLT3-ITD mutant clone, and other cell strains all do not have the FLT3-ITD sudden change) is with containing the IMDM perfect medium of 10% foetal calf serum, 100U/ml penicillin, 100 μ g/ml Streptomycin sulphates at 5%CO 2, under 37 ℃ of conditions.
2 experimental techniques and result
2.1 experimental technique (mtt assay)
Adjusting cell concn with complete culture solution is 1-2 * 10 4The cell suspension of individual/ml, be inoculated in 96 orifice plates, every hole 200 μ l cell suspensions, overnight incubation, handle cell with the 4-arylthio quinazoline derivant of gradient concentration respectively and (directly use the substratum suspendible cell that contains the different concns compound for suspension cell next day, and the 3-10 that its cell starting point concentration is an attached cell doubly), establish the negative control group and the isopyknic solvent control group that do not contain medicine simultaneously, DMSO concentration is 0.1%, and each dosage group is established 3 multiple holes, at 37 ℃, 5%CO 2Cultivate under the condition.After 48 hours, every hole adds 5mg/ml MTT reagent 20 μ l, continues to cultivate 2-4h, abandons supernatant, adds DMSO150 μ L again, vibration mixing 15min, and (λ=570nm) measure absorbancy (A) value (the A value is directly proportional with viable count) gets its mean value with microplate reader.Relative cell proliferation inhibition rate=(control group A 570-experimental group A570)/control group A 570 * 100%.Experiment repeats 3 times at least.Experimental data represents that with mean the data statistics data adopts the t check, and there is statistical significance P＜0.05 for difference.Below each compound on cell proliferation restraining effect all represent with IC50 or inhibiting rate.Detected result sees Table 2 and Fig. 2, Fig. 3 and Fig. 4.
