Reviews on natural naphthoquinones and their bioactivities / 中国中药杂志

ABSTRACT

The naphthaquinones are widely distributed in plants. They are usually in higher plants, but a few of them were also found in microorganisms. There is a lot of research showing that they had multiple pharmaco-activities such as cytotoxic, antioxidant, anti-inflammatory and antibacterial activities, etc. In recent years, they have attracted extensive attention at home and abroad especially in terms of the anti-tumor activity. For further research, 69 new natural naphthoquinones reported in the last five years (2013-2017) were reviewed. They were divided into five major types simple 1,4-naphthoquinones, furan and pyran naphthoquinones, 1,2-naphthoquinones, naphthohydroquinones and naphthoquinone polymers, which showed cytotoxic, antioxidative, anti-inflammatory and antibacterial biological activities, et al. The research of these compounds in the future was also proposed.
