Description

The method for preparing azolopyrimidines
The present invention relates to a kind of method for preparing new pyrrolo-[2,3-d] pyrimidine derivatives, this derivative can be used as anticarcinogen effectively; The invention still further relates to intermediate of this derivative and preparation method thereof.
In organism as formic acid, a carbon (C of formaldehyde etc. 1) folic acid of unit transfer agent, in various enzymatic reaction systems, play a part coenzyme.For example, synthetic at biological nucleic acid, in amino acid peptide metabolism and the methane formation system.Specifically, in the biological nucleic acid synthesis system, this compound is absolutely necessary concerning the formylation reaction of two kinds of biosynthetic pathways of nucleic acid (being purine nucleotides approach and thymidine Nucleotide approach).In order to prove its biological activity, folic acid generally will be through two step reduction reactions, to be converted into active coenzyme.(methotrexate: be the medicine of known desmoenzyme consumingly (Tetrahydrofolate dehydrogenase) with similar compound MTX), this class medicine can be controlled its subordinate phase to methotrexate, becomes tetrahydrofolic acid (THFA) thereby suppressed dihydrofolate reduction.These medicines (play the effect of weakening DNA synthetic, cause necrocytosis) have been developed into cancer therapy drug, and have occupied very important position as clinical medicine at present.On the other hand, a kind of new tetrahydrochysene aminopterin anticarcinogen (5 has been proposed, 10-azatropylidene-5,6,7,8-tetrahydrochysene aminopterin: DDATHF), it has the basic framework of pteridine ring, but its mechanism of action is different with the medicine of this similar, and Tetrahydrofolate dehydrogenase is not suppressed active, and mainly be (the medical chemistry magazine 28,914 (1985)) finished by the mechanism that in the initial step of purine biosynthetic pathway, suppresses G-NH2 " nucleosides " transfer Formylase.
The MTX that has proposed clinical medicine commonly used mainly is the anticarcinogen by the folic acid antagonist effect one by one.But, therefore can not obtain satisfactory therapeutic effects because this medical instrument has stronger toxicity and little to the solid tumor effect.In addition, also exist the tumour cell resistance problem serious to this medicine.Therefore, the cancer therapy drug that can demonstrate improved efficient and cancer cells be demonstrated selective toxicity with the new mechanism of action is developed in special at present expectation.
According to above situation, the inventor has carried out research extensively and profoundly to the antitumour activity of the method for preparing no pteridine ring compound and this compound.So the inventor has proposed the novel method of pyrrolo-[2, the 3-d] pyrimidine derivatives of preparation 5-replacement, the selectivity that described derivative forms at productive rate, pyrrole ring etc. has the industrialization advantage; And the inventor finds that also a large amount of new compound that is made by this production method can have powerful inhibition growth activity to human body tumour cell.Just set up the present invention based on above discovery.
