Research progress on natural guaiane-type sesquiterpenoids and their biological activities / 中国中药杂志

ABSTRACT

Guaiane-type sesquiterpenoids are a class of terpenoids with [5,7] ring-fused system as the basic skeletal structure composed of three isoprene units, which are substituted by 4,10-dimethyl-7-isopropyl. According to the difference in functional groups and degree of polymerization, they can be divided into simple guaiane-type sesquiterpenoids, sesquiterpene lactones, sesquiterpene dimers, and sesquiterpene trimers. Natural guaiane-type sesquiterpenoids are widely distributed in plants, fungi, and marine organisms, especially in families such as Compositae, Zingiberaceae, Thymelaeaceae, Lamiaceae, and Alismataceae. Guaiane-type sesquiterpenoids have good antibacterial, anti-inflammatory, anticancer, and neuroprotective effects. In this paper, the novel guaiane-type sesquiterpenoids isolated and identified in recent 10 years(2013-2022) and their biological activities were reviewed in order to provide refe-rences for the research and development of guaiane-type sesquiterpenoids.
