Problems solved by technology

However, while anthracyclines have high-efficiency anticancer effects, they are also highly toxic to cardiomyocytes.
In addition, long-term use of anthracycline antitumor antibiotics is prone to drug resistance, including cross-resistance between this class of drugs and cross-resistance to vincristine, which limits the wide application of anthracyclines in clinical practice. application

[0042]

Embodiment 1

[0043] The preparation of embodiment 1 sulfonyl ester group anthraquinone derivatives (C01-C16)

[0044] (1) Preparation of 1,4-bis(1,1'-biphenyl)-4-sulfonate)-9,10 anthraquinone (C01):

[0045] Add 0.5 g (2 mmol) of 1,4 dihydroxyanthraquinone, 1.2 g of excess 4-biphenylsulfonyl chloride, and 0.5 g of anhydrous potassium carbonate to a glass flask in sequence, then add 20 mL of anhydrous acetone, and react in an oil bath at 60°C Under reflux reaction, TLC monitors the reaction throughout the whole process. After the reaction is complete, add an appropriate amount of ice water to quench the reaction, filter to obtain a light yellow crude product, and purify it by silica gel column chromatography. Eluent: (dichloromethane:petroleum ether=1:2), The light yellow target compound was obtained with a yield of 74%.

[0046] (2) Preparation of 1,4-bis(2-naphthalenesulfonate)-9,10 anthraquinone (C02):

[0047] Add 0.5g (2mmol) of 1,4-dihydroxyanthraquinone, 1.4g of excess 2-naphthalen...

Embodiment 2

[0076] The preparation of embodiment 2 sulfonyl ester group anthraquinone derivatives (C01-C16)

[0077] (1) Preparation of 1,4-bis(1,1'-biphenyl)-4-sulfonate)-9,10 anthraquinone (C01):

[0078] Add 0.1kg of 1,4-dihydroxyanthraquinone, 0.5kg of excess 4-biphenylsulfonyl chloride raw material, 0.1kg of anhydrous potassium carbonate, and then add 4L of anhydrous acetone in a stainless steel reaction kettle, and react in an oil bath at 60°C Reflux reaction, TLC monitors the reaction throughout the whole process, after the reaction is complete, add an appropriate amount of ice water to quench the reaction, filter to obtain a light yellow crude product, purify by silica gel column chromatography, eluent (dichloromethane:petroleum ether=1:2), and obtain pale yellow product Yellow target compound, yield 65%.

[0079] (2) Preparation of 1,4-bis(2-naphthalenesulfonate)-9,10 anthraquinone (C02):

[0080] Add 0.1kg (0.4mol) of 1,4-dihydroxyanthraquinone, 0.5kg of excess 2-naphthalenesu...

Abstract

The invention discloses a sulfonyl ester anthraquinone derivative, a preparation method and application thereof. The sulfonyl ester anthraquinone derivatives of the present invention have good anti-tumor activity, and the half maximal inhibitory concentrations to Hela, MCF-7, A549, CNE2 and other cell lines are all less than 100 μmol / mL, and have no inhibitory effect on normal cells. The invention introduces a sulfonyl ester group on the anthraquinone core to improve its water solubility and acidity and alkalinity, so as to improve the antitumor activity of the anthraquinone compound, and the preparation method is simple and feasible. The sulfonyl ester anthraquinone derivatives of the invention have wide potential applications in fluorescent materials, medicine, pesticides, materials and the like, especially in the preparation of anticancer drugs.

Description

technical field [0001] The invention relates to anthraquinone derivatives, in particular to a sulfonyl ester anthraquinone derivative, a preparation method thereof and an application in pharmacy. Background technique [0002] Cancer is the main cause of threat to human health and death. About 10 million people are diagnosed with tumors every year, and due to the acceleration of the aging process, the incidence of cancer worldwide continues to rise. It is estimated that by 2020, there will be 16 million new cancer cases each year. At present, the treatment methods for tumors mainly include five categories: surgery, radiation therapy, chemotherapy, biological targeted therapy, and traditional Chinese medicine therapy, while biological targeted therapy and traditional Chinese medicine therapy are relatively seldom used. Surgical treatment is an important method to achieve the treatment of tumors by means of surgical resection of tumors. The effect of treating early tumors is o...
