BACKGROUND OF THE INVENTION
1. Field of the Invention
The current invention is related to pharmaceutical chemistry, and more particularly to a method to produce halogenated dideoxy sugar derivates as well as their applications.
2. Description of the Related Art
In the last 30 years, more and more biological functions of sugars have been revealed. Scientists have found out that sugars can boost immune system and have anti-bacteria and anti-tumor effects. One kind of sugars is named as 2-deoxy-glucose, whose structural characteristic is that the —OH on 2 position of the sugar ring is replaced by H, alkyl, amino group, and other functional groups. This kind of sugar has anti-tumor effect. In 1982, George Tidmarsh et al., U.S. Pat. No. 6,979,675 entitled “Treatment of cancer with 2-deoxyglucose” is based on the anti-tumor effect of 2-DG (2-deoxygluclose). Until now, the research on deoxy sugar has been extended to multi-deoxy sugars and their derivatives. In PCT/US2009/045157, 2-halogenated-deoxyglucose and 3,4-deoxymannitose have been mentioned. However, when studying the mechanisms of the deoxy sugars, scientists have shown that pure 2-deoxyglucose does not possess very pronounced anti-tumor effect. Therefore, scientists have strived to find a deoxy sugar, which is easier to absorb and has a more potent anti-tumor effect.
The inventor of the current invention has discovered that, when acetylated and halogenated, deoxy sugars can be more easily absorbed and enter into cancer cells faster. In addition, when the hydroxyl group on its 1 position is halogenated, the halogenated deoxy sugar formed has a much stronger effect (according to normal tumor cell test), and it is also easier to product derivates. Furthermore, when combined with mustine, podophyllotoxin and other anti-tumor functional groups, the anti-tumor function of acetylated deoxy sugars can be significantly enhanced. This kind of sugars possess general anti-tumor effects, not only to common cancers, such as stomach cancer, esophagus cancer, liver cancer, bile cancer, rectum cancer, intestinal cancer, lung cancer, rhinopharyngocele, prostate cancer, nervous system cancer, breast cancer, ovarian cancer, cervis cancer, etc., but also to malignant melanoma, pancreas cancer, anaplastic thyroid carcinoma, metastatictumorofbone, leukemia and other malignant cancers. During the study of their mechanisms, it has been shown that after these compounds enter cancer cells, with various enzymes, they are first deacetylated, their glycosidic bonds are split and form deoxy sugar, and mustine, podophyllotoxin, which act on tumor cells simultaneously so that double anti-tumor functions are achieved.
SUMMARY OF THE INVENTION
The technical problem of the current invention is to overcome the drawbacks present in the current state of the art, and to remedy the structure of deoxy sugar so that it has double anti-tumor effects and a wider treatment scope and can be used to treat malignant melanoma, pancreatic cancer, anaplastic thyroid carcinoma, metastatic tumor of bone, leukemia and other highly malignant carcinomas.

The current invention uses sugar as starting material to synthesize compound 1-14. Since the sugar rings of all the compounds are acetylated hydrophobic esters, they are very easy to be crystallized. The compounds are chemically and enzymetically stable. They are easy to spread after enter the human body and can be absorbed by cancer cells without consuming any energy. Inside cancer cells, they release the anti-cancer elements, dideoxy sugar, mustine, podophyllotoxin with the help of esterase, acylase and glycosidase and the double anti-tumor effect can be achieved.
The inventor of the current invention has discovered that after the deoxy sugar is acetylated and brominated, the compound is more ready to be absorbed and the anti-tumor effect thereof is significantly better than deoxy sugar. In addition, when the compound is deacetylated, its anti-tumor effect is also significantly improved. However, it is more difficult to be crystallized and therefore acetylated compound is more preferred.
The compound of the current invention can be combined with appropriate excipients and be made into oral medications or non-oral injective agents or external medication. Such as orally administrated pills, capsules, tablets, oral liquids, injections, powder injector, patch or cream.
The compounds of the current invention can be used to treat malignant melanoma, pancreas cancer, anaplastic thyroid carcinoma, metastatic tumor of bone, leukemia, lymphoma, osteoma, chondrosarcoma, prostate cancer, esophagus cancer, stomach cancer, liver cancer, carcinoma of gallbladder, rectum cancer, intestinal cancer, colorectal cancer, lung cancer, prostate cancer, nervous system cancer, breast cancer, ovarian cancer, cervis cancer.

Compound 3, 5, 7, 10, 12, 14 (the preparation of experiment 2, 3, 4, 5, 6, 8) were applied at a concentration of 125 mg/kg. Saline solution was used as a control. The positive group CTX was treated with the compounds at an amount of 0.4 ml/20 g. The compounds were applied once a day for consecutive 7 days. The animals were then compensated. Anti tumor experiments were carried out on B16 malignant melanoma, AsPc human pancreatic cancer cells, 05-732 human bone tumor, anaplastic thyroid carcinoma TA-K cells, MX-1 human breast cancer cells and MGC human stomach cancer cells respectively.
