Paeonol derivatives and their pharmacological activities / 中草药

ABSTRACT

Paeonol has a wide range of pharmacological activities. It is mainly used to protect cardiovascular and cerebrovascular system, promote microcirculation, antibacterial and anti-inflammatory, antitumor, anti-oxidation, anti-allergic reaction, enhance immunity, and treat diabetic osteoporosis, etc. In recent years, it not only improves the method of artificially synthesizing paeonol, but also carries out a large number of structural modification and transformation of paeonol. Five major parts, carbonyl, phenolic hydroxyl, carbonyl α-H, methoxy, and benzene rings, have been mainly modified. About 16 kinds of paeonol derivatives were produced including carboxylic acid esters, sulfonates esters, phosphates esters, ethers, NO donors, glycosidation, paeonol sodium, Schiff bases, thiazoles, oximes, hydroxyalkylation, α,β-unsaturated ketones, aminomethylation, α-H halogenation, demethylation, and benzene ring halogenation. In this paper, the derivatives of paeonol and their pharmacological activities were reviewed in combination with the literatures on paeonol derivatives at home and abroad. This article may provide basis for further study of this type of compound.
