Abstract

The invention discloses 2-methoxyestramustine and a derivative thereof. The structural formula of the 2-methoxyestramustine is shown as a formula 1-4. According to the 2-methoxyestramustine disclosedby the invention, 2-methoxyestradiol is used as a carrier, an alkylating agent (nitrogen mustard) is connected through carbamate to form a bifunctional drug molecular compound, the whole molecule is used as an anti-mitotic agent, and after carbamate is metabolized and hydrolyzed in vivo, 2-methoxyestradiol released by metabolite mediation can still continue to play an anti-tumor role. The derivative of the 2-methoxyestradiol can be used as the prodrug of the 2-methoxyestradiol. The invention also discloses a preparation method of the 2-methoxyestramustine and the derivative thereof, the preparation method can be used for preparing the 2-methoxyestramustine and the derivative thereof, and the yield is relatively high. The invention further discloses application of the 2-methoxyestramustineand the derivative thereof in a medicine for treating tumors or multiple myeloma.

Description

technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a class of novel compound 2-methoxyestramustine and its derivatives, preparation method and application. Background technique [0002] At present, with the improvement of medical level, great progress has been made in tumor treatment. The survival period of cancer patients has been significantly prolonged and the quality of life has been significantly improved, mainly due to the invention and clinical application of various high-efficiency anti-cancer and anti-tumor drugs. . However, some tumor drugs currently used clinically, while achieving remarkable curative effects, are often accompanied by some side effects and adverse reactions, which cause great pain to patients and seriously affect the quality of life of patients. [0003] Nowadays, there are many kinds of antineoplastic drugs clinically used, and nitrogen mustard antineoplastic drugs are one of them, such as ...
