Abstract

The invention discloses application of the Cryptotanshinone in preparation acute lymphoblastic leukemia chemical therapy sensitivity-enhancing;And the application of Cryptotanshinone and anticancer drug combination in the drug of the treatment of preparation acute lymphoblastic leukemia and/or prophylactic agent, drug resistance inversion drug and/or the recurrence of pre- rear defence.The research of the invention finds that, when by Cryptotanshinone and anticancer drug combined effect, Cryptotanshinone can greatly increase leukaemia cell to the sensibility of anticancer drug, explosion type improves a variety of anticancer drugs to the proliferation inhibiting effect of acute lymphoblastic leukemia cell, to make the usage amount of each drug be far below the drug usage amount of Present clinical, and realize the effect of explosion type synergy.Therefore, chemical therapy sensitivity-enhancing of the Cryptotanshinone as effective acute lymphoblastic leukemia in the present invention has important research meaning and broad application prospect in treatment acute lymphoblastic leukemia and in terms of solving acute lymphoblastic leukemia resistance problems.

Description

Cryptotanshinone is in preparing Ph+ acute lymphoblastic leukemia chemical therapy sensitivity-enhancing Using
Technical field
The invention belongs to biomedicine technical fields, more particularly, to Cryptotanshinone in preparation Ph+ acute lymphoblastic Application in leukemia chemotherapy hypersitization medicine.
Background technique
Leukaemia is commonly called as " leukemia ", is a kind of Hematological malignancies disease for deriving from candidate stem cell, it is thin to be divided into lymph Born of the same parents' leukaemia and myelocytic leukemia.Lymphocytic leukemia is divided into acute lymphoblastic leukemia (ALL) and chronic lymphatic Chronic myeloid leukemia (CLL), wherein the disease progression of Ph+ acute lymphoblastic leukemia (Ph+ALL) is rapid, grade malignancy is high, Poor prognosis.For the drug-TKI inhibitor (such as Imatinib) of targeting Philadelphia chromosome (Philadelphia, Ph), suffer from Curative effect when person takes in the early stage is good, but offer limited effectiveness, while will occur drug resistance phenomenon quickly.
It is often selected TKI inhibitor (such as above situation in clinical treatment Ph+ acute lymphoblastic leukemia Imatinib) it is used in combination with the cytotoxic chemotherapy agents (such as: cyclophosphamide, methotrexate) of wide spectrum, with enhancing Curative effect of medication postpones drug resistance phenomenon.However, there is also very big problems in the application for above-mentioned therapy: firstly, being hindered with the cell cycle Although Common Chemotherapy scheme based on stagnant medicine prevents the abnormality proliferation of leukaemia cell, but it is thin also seriously to hinder normal body The division of born of the same parents;Second, chemotherapeutics metabolic process is complicated, damages to vitals such as the heart of patient, liver, kidneys serious;Third, often Though disease can be alleviated rapidly with chemotherapy, easily generation drug resistance and recurrence.
And the advantages such as native compound is significant in efficacy with its, cheap and easy to get, toxic side effect is low attract the sight of people, it will The native compound and existing anticancer drug that cell chemosensitivity can be increased are used in combination, and can not only lower medicine significantly The usage amount of object reduces toxic side effect, can also delay or even avoid the generation of drug resistance phenomenon.Therefore, thin in Ph+ acute lymphoblastic Born of the same parents' leukemia treating field, need to develop one kind can greatly enhance Ph+ acute lymphoblastic leukemia cell chemosensitivity, Reverse the lesser natural drug of drug resistance and toxic side effect to anticancer drug.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defect of the above-mentioned prior art and deficiencies, provide a kind of acute lymphoblastic Chronic myeloid leukemia chemical therapy sensitivity-enhancing.The research of the invention finds that Cryptotanshinone (Cryptotanshinone, abbreviation CPT) can With anti-cancer agent in combination compatible use, cause the cooperative synergism effect of explosion type.Such as Imatinib (Imatinib, abbreviation IM), The research of the invention finds that Cryptotanshinone can greatly increase white blood with using Imatinib as the TKI inhibitor compatible use of representative Sick cell can improve a variety of anticancer drugs to acute lymphoblastic leukemia cell to the sensibility of anticancer drug with explosion type Proliferation inhibiting effect realizes synergistic effect, so that the usage amount of each drug be made to use far below the drug of Present clinical Amount achievees the effect that low dosage, high efficiency kill Ph+ acute lymphoblastic leukemia cell.Simultaneously the study found that Cryptotanshinone With with triptolide (Triptolide, abbreviation TRI) be representative high toxicity anticancer drug and with qinghaosu (Artemisinin, abbreviation ATS) is that the inefficient anticancer drug of representative distinguishes compatibility, can reach similar synergistic function, Low dosage, high efficiency kill the effect of Ph+ acute lymphoblastic leukemia cell.Simultaneously as Chinese herbal medicine Cryptotanshinone low toxicity And abundance, material are easy to get, and can greatly reduce drug in therapeutic process to the toxic side effect of body, and significantly reduce treatment Cost.Therefore, Cryptotanshinone is expected to be developed into the chemical therapy sensitivity-enhancing for Ph+ acute lymphoblastic leukemia, is applied to Prepare acute lymphoblastic leukemia treatment and/or prophylactic agent, acute lymphoblastic leukemia drug resistance inversion drug and/or The drug of pre- rear defence recurrence improves in the drug of immunity of organisms, and is applied to acute lymphoblastic leukemia clinic and base In the correlative study of plinth.
The first purpose of the invention is to provide Cryptotanshinones in preparation acute lymphoblastic leukemia chemical therapy sensitivity-enhancing In application.
A second object of the present invention is to provide Cryptotanshinones and anticancer drug combination to prepare the white blood of acute lymphoblastic The treatment and/or the application in prophylactic agent of disease.
Third object of the present invention is to provide Cryptotanshinones and anticancer drug combination to prepare the white blood of acute lymphoblastic Application in sick drug resistance inversion drug and/or the drug of pre- rear defence recurrence.
Fourth object of the present invention is to provide a kind of therapeutic agent of acute lymphoblastic leukemia.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
The research of the invention finds that the Cryptotanshinone and anti-cancer agent in combination of denier (being greater than or equal to 1nmol/L) use When, can make Cryptotanshinone itself and associated with anticancer drug dosage sharp fall, well below its be used alone IC50 Concentration (half-inhibitory concentration of cell Proliferation), and make acute lymphoblastic leukemia cell be proliferated inhibiting rate reach 66% with On, cause the cooperative synergism effect of explosion type.Wherein, the effective activity of Cryptotanshinone is more than or equal to 1nmol/L. Pass through research, it has been found that Cryptotanshinone is a kind of good acute lymphoblastic leukemia chemical therapy sensitivity-enhancing, be can be used for big Width increases acute lymphoblastic leukemia cell to the drug susceptibility of anticancer drug;Using the preparation comprising Cryptotanshinone and/ Or Cryptotanshinone and anti-cancer agent in combination use and are applied to preparation acute lymphoblastic leukemia chemical therapy sensitivity-enhancing, can solve The problem of weak curative effect as caused by drug is insensitive or drug resistance, recurrence or treatment failure.Wherein, due to Cryptotanshinone and Imatinib is the drug of existing clinical application, and the drug combination mode of Cryptotanshinone and Imatinib can be rapidly in clinic Mature application in acute lymphoblastic leukemia is treated, is no longer needed to by very long clinical stage, application prospect is very good.
