example 1

[0027] Example 1: The synthetic method of formula I class shikonin derivatives

[0028] Dissolve 50mmol of shikonin and 50mmol of the corresponding carboxylic acid in 20mL of anhydrous dichloromethane, and continue to add catalytic amounts of N,N-dicyclohexylcarbodiimide (DCC) and 4-Dimethylaminopyridine (DMAP), followed by TLC detection to generate corresponding ester derivatives. Add an appropriate amount of silica gel to concentrate the solvent under reduced pressure, and perform column chromatography with ethyl acetate:petroleum ether=1:4 to obtain the corresponding shikonin carboxylate derivatives.

[0029] The reaction takes 2,2-difluoroacetic acid as an example:

Abstract

The invention belongs to the technical field of chemical pharmacy, particularly relates to preparation of a derivative containing fluorine carboxylic acid ester and application of the derivative in tumor inhibition. The ester derivative is obtained by intriducing fluorocarboxylic acid in shikonin framework molecules through a synthetic method. An in-vitro antitumor activity study shows that the derivative containing the fluorocarboxylic acid has strong inhibition activity to tumor cell lines.

Description

1: Technical field [0001] The invention belongs to the technical field of chemical pharmacy, and in particular relates to the preparation of a class of fluorine-containing carboxylic acid ester derivatives and their application in tumor suppression. Two: background technology [0002] Shicaoning has broad-spectrum activity, and because of its obvious bactericidal activity, it was also used in daily necessities in the early days. Numerous studies in recent years have shown that it is an anti-tumor functional molecule with great potential. However, because it is a completely fat-soluble natural product, problems such as water solubility and side effects will be encountered during application. These drawbacks restrict the possibility of shikonin becoming a drug. How to solve these problems is the key to the drug The primary task. [0003] In order to obtain high-efficiency shikonin derivatives, many research groups have carried out the preparation and activity research of cor...
