Description

Fluorine-containing water solubility platinum complex and Preparation method and use
Technical field
The present invention relates to a kind of fluorine-containing water-soluble platinum complex and preparation methods.
Background technique
Platinum class anticarcinogen is the representative a kind of drug of therapeutic field of tumor.It belongs to non-specific cell cycle medicine Object all has therapeutic efficiency to sarcoma, carcinoma, lymthoma and germinoma.It answers extensively in the world at present Representative platinum class anticarcinogen for clinical treatment mainly has, cis-platinum, carboplatin and oxaliplatin.
The fatal defects of platinum-containing anticancer drug are that have extremely strong toxic side effect and drug resistance that is intrinsic and being subsequently formed Property problem.It is metallo-organic compound additionally, due to such drug, all generally existing water solubilitys of platinum class marketed drug are extremely low Characteristic, following table are the water solubility datas of above-mentioned three kinds of listings clinical medicine:
Drug Cis-platinum Carboplatin Oxaliplatin
Water-soluble (mg/ml) 1.0 17.0 6.0
Studies have shown that tumour includes that tumour cell enters carefully drug the reason of forming drug resistance to platinum series antineoplastic medicament The interception of born of the same parents and outside repulsive interaction are to reduce platinum medicine in savings (the Holzer AK, Manorek of tumour cell GH,Howell SB.Molecular Pharmacology(Internet).2006；70 (4): 1390-4.), therefore how to have It is that exploitation has targeting a new generation platinum class anti-that effect ground, which improves platinum medicine in the selective aggregation of tumour cell and tumor tissues, Cancer drug needs one of the key scientific problems solved.
The tracer 18F-DG (fluoro -2-deoxy-D-glucose) for diagnosing for clinical tumor and checking by stages is clinical Most common imaging agent.Its principle is tumour cell to maintain the needs of fast breeding and transfer, and height expresses glucose transport Albumen (GLUT) is to draw a large amount of glycan molecule nutriment.By injecting the 18F- that radioactive label fluorine atom replaces to patient After DG, drug is accumulated in tumour cell, and the diagnosis of malignant tumour then may be implemented by whole body PET imaging, benign and pernicious Identify, clinical stages, therapeutic evaluation and detection recurrence etc..But 18F-DG, which is only limited to diagnostic uses, itself does not have therapeutic effect.
Further, since it is too low it is water-soluble not only brought to the stability of medicine preparation and clinical application it is many unfavorable It influences, for example is difficult they to be successfully configured to a kind of convenience and the clinical medicament with suitable concentration.Moreover, too low medicine Object water solubility also directly influences drug in the intracorporal savings of body and metabolism, and the platinum-like compounds containing metallic atom are especially in medicine Excretion of object etc. is influenced more significant by water-soluble, and putting aside platinum medicine in renal tissue and blood cannot be by body Body is discharged in time to be formd platinum medicine generally and has the characteristics that very virulent side effect.It is various below with novel chemical structure Platinum series antineoplastic medicament due to water solubility cannot be improved and thus caused by the sincere drug savings type toxic side effect of weight and It is forced to stop the drug case of clinical test:
(bibliography: Status of platinum drugs in the clinic and in clinical trials,Dalton Transactions,2010,39,8113-8127.)
In conclusion the tumor-targeting and water solubility problems of solution platinum medicine are that platinum class anticarcinogen is ground in the world at present Hair field absorbed most important project (Galanski, Markus；Keppler,Bernhard K Searching for the Magic Bullet:Anticancer Platinum Drugs Which Can Be Accumulated or Activated In the Tumor Tissue.Anti-Cancer Agents in Medicinal Chemistry, (2007), 7,55- 73)。

Experiments have shown that: fluorine-containing water-soluble platinum complex provided by the invention has good anti-tumor activity.Institute of the present invention The fluorine-containing water-soluble platinum complex provided is for including intestinal cancer, breast cancer, prostate cancer, the antitumor pharmacodynamic test of lung cancer etc. In, anti-tumor activity can compare favourably with the cis-platinum that is widely used at present, carboplatin or oxaliplatin, and activity is even higher than These existing platinum-containing anticancer drugs.In addition, complex provided by the present invention is capable of forming by force for the antitumaous effect of cis-platinum The mouse Leukemia-L1210 tumour cell of strong drug resistance has more effective lethal effect.This is because provided by the present invention Fluorine-containing water solubility platinum complex in terms of water solubility compared with existing platinum antineoplastic drug, all with tens times of raising, this Kind of highly-water-soluble feature can theoretically increase and improve drug in the excretion of kidney, mitigate platinum medicine generally there are height Kidney toxic side effect, while so that these compounds is easy formulation and clinically application more convenient for this highly-water-soluble characteristic.
Complex of the invention, since its water-soluble administration route for having high is not particularly limited, dosage is not It is only dependent upon the age of patient, weight and the state of an illness, additionally depends on the type of tumour, property and severity.But in general, For adult patient, the amount preferably used daily is between 10 milligrams to 1 gram.It is generally each to using once in three weeks or several times Medicine.
