Coptisine from Coptis chinensis exerts diverse beneficial properties: A concise review

Jiasi Wu et al. J Cell Mol Med. 2019 Dec.

Abstract

Coptisine is a natural small-molecular compound extracted from Coptis chinensis (CC) with a history of using for thousands of years. This work aimed at summarizing coptisine's activity and providing advice for its clinical use. We analysed the online papers in the database of SciFinder, Web of Science, PubMed, Google scholar and CNKI by setting keywords as 'coptisine' in combination of 'each pivotal pathway target'. Based on the existing literatures, we find (a) coptisine exerted potential to be an anti-cancer, anti-inflammatory, CAD ameliorating or anti-bacterial drug through regulating the signalling transduction of pathways such as NF-κB, MAPK, PI3K/Akt, NLRP3 inflammasome, RANKL/RANK and Beclin 1/Sirt1. However, we also (b) observe that the plasma concentration of coptisine demonstrates obvious non-liner relationship with dosage, and even the highest dosage used in animal study actually cannot reach the minimum concentration level used in cell experiments owing to the poor absorption and low availability of coptisine. We conclude (a) further investigations can focus on coptisine's effect on caspase-1-involved inflammasome assembling and pyroptosis activation, as well as autophagy. (b) Under circumstance of promoting coptisine availability by pursuing nano- or microrods strategies or applying salt-forming process to coptisine, can it be introduced to clinical trial.

Keywords: coptisine; crosstalk network; pharmacological mechanism; signalling pathways bioavailability.

Recommendations for future investigations on coptisine. Once mitochondrion is damaged, PARK2 binds to PINK1 on the surface of mitochondrial and ubiquitinates mitochondrial outer membrane proteins, which then bind to SQSTM1, a receptor which can interact with LC3. The formation of autophagosome inhibits ROS, the overproduction of which causes NLRP3 inflammasome assembling and the downstream pyroptosis and inflammatory response
