AI Technical Summary

Problems solved by technology

However, the clinical application of mangiferin is greatly limited due to poor solubility and other reasons. Therefore, we synthesized a series of mangiferin compounds with mangiferin as the lead compound, and then screened the prepared compounds for PTP1B inhibitory activity in order to find out highly active compound
At present, there are no such research reports at home and abroad

Abstract

This invention discloses compounds with natural product mangiferin as the frame. The general chemical structure of the compounds is shown in formula I, wherein, R1 and R2 are C1-20 linear or branched alkyl, benzyl, or substituted benzyl. The substituent is halogen, alkyl, etc. The compounds have strong inhibitive activity on protein tyrosine phosphatase 1B (PTP1B). This invention also discloses a method for preparing the compounds. The compounds can be used to treat diseases related to PTP1B inhibition, including diabetes type 2.

Description

technical field [0001] The invention relates to a mangiferin compound, a preparation method thereof and an application in the field of medicine. Background technique [0002] Mangiferin, also known as mangiferin and Zhimuning, is a natural polyphenol compound extracted from Liliaceae Anemarrhena, molecular formula: C 19 h 18 o 11 , molecular weight: 422. Its chemical structure is as follows: [0003] [0004] The compound can also be extracted from the leaves, fruits, and bark of mango trees and almond trees of Anacardiaceae; Northeast Gentiana and Western Sichuan Swert of Gentianaceae; Guangshiwei, a plant of Water Keelaceae.
