Abstract
The invention relates to a preparation method of novel substituted 10-hydroxycamptothecine 10-position derivatives and an application in antitumor drugs. With 10-hydroxycamptothecine as a raw material and through a condensation reaction and a substitution reaction, the derivatives having anti-cancer activity and capable of increasing water solubility of 10-hydroxycamptothecine are obtained for the first time.
Description
Technical field
The invention belongs to new compound preparation method field, especially a kind of 10-hydroxycamptothecine 10 bit derivant preparation methods and the application in antitumor drug thereof of novelty.
Background technology
Estimate according to the World Health Organization, the whole world approximately has 5,000,000 people dead because suffering from various malignant tumours every year, and only the U.S. diagnoses out 1,300,000 routine cancers every year.Cancer has become serious harm human life health and has been difficult to one of disease of curing.Camptothecine (CPT) is a kind of cancer therapy drug that derives from plant, the camplotheca acuminata Central-South from China, southwest distributes, extracts and obtains.Early stage biological test shows, natural camptothecine has obvious anti-tumor activity, especially digestive tube, leukemia, bladder cancer etc. is had to significant result for the treatment of.
Camptothecin analogues is the inhibitor of efficient topoisomerase I.Its antitumor mechanism is by the mixture of stable topology isomerase I-DNA, affect DNA copy to realize.The camptothecine of lactonic ring form acts on the binding site of topoisomerase I-DNA mixture, forms stable CPT-DNA-Topol ternary complex, makes DNA break.In the S phase of cell cycle, DNA replication dna fork runs into the roadblock that ternary complex forms, and has suppressed the synthetic of DNA, finally causes the apoptosis of cell in the s cycle.
Wherein anticarcinogen 10-hydroxycamptothecine has gone through to go on the market in China.But clinical application 10-hydroxycamptothecine is not modified natural product, and toxicity is larger, and anti-tumor activity is lower, thereby is restricted in clinical application.Anticarcinogen 10-hydroxycamptothecine is carried out to structural modification research, further develop derivative that curative effect is more good by significant.For improving the result for the treatment of of medicine, reduce toxic side effect, adapt to preparation requirement, convenient application, keeps the basic structure of anticarcinogen 10-hydroxycamptothecine herein, neither destroys vinegar ring in it, improve again that it is water-soluble, only on some function base, make certain chemical structure and change.Select appropriate structural modification, make, under physiological condition, can discharge parent drug, and have the difference of the conditions such as enzyme, acceptor, pH according to body tissue, and reach following object: improve transhipment and the metabolic process of medicine, improve bioavailability; Improve physical and chemical properties of drugs; Be conducive to the interaction of medicine and acceptor or enzyme, cause the transformation of corresponding biological chemistry and biophysics.Finally develop the new drug with wide market outlook, bring benefit to the mankind.
Summary of the invention
The object of the present invention is to provide 10-hydroxycamptothecine 10 bit derivants and preparation method thereof and application thereof, that the present invention has is simple to operate, reaction conditions is gentle, synthetic route is short, yield is higher, low cost and other advantages.
Object of the present invention is achieved through the following technical solutions:
10-hydroxycamptothecine 10 bit derivants, is characterized in that: the general structure of derivative is as follows:
