AI Article Synopsis
- Juncus species are traditional sources of phenanthrene compounds used in Chinese medicine, particularly effusol and juncusol, which have shown antimicrobial and anticancer properties.
- This study investigated their effects on the growth and biochemical processes of the model plant Arabidopsis thaliana, focusing on how these compounds influence polyamine metabolism.
- Results indicated that while phenanthrene is toxic to plant growth, both effusol and juncusol promote biomass increase and improve antioxidant defenses, suggesting their potential as biopesticides or plant growth stimulants.
Article Abstract
Juncus species are valuable sources of phenanthrene compounds that have been used in traditional Chinese medicine for thousands of years. Effusol and juncusol are the most investigated compounds reported to have antimicrobial and anticancer effects; however, to date, their effects on higher plants have not been investigated. In this study, we examined the effects of effusol and juncusol on the growth and other biochemical parameters of the dicot model plant Arabidopsis thaliana in a concentration-dependent manner with a focus on polyamine metabolism. Phenanthrene induced toxic effects on plant growth and development, while effusol and juncusol induced higher biomass and maintained antioxidant defence mechanisms associated with reduced polyamine degradation. Taken together, our results suggest that these compounds could be good candidates for new biopesticide or biostimulant plant growth regulators in the future.

Phenanthrenes and their derivatives have biological relevance owing to their antimicrobial, antioxidant, and cytotoxic effects on cancer cells. They can be efficiently analyzed through ultrahigh-performance liquid chromatography coupled to tandem high-resolution mass spectrometry (UHPLC-MS/HRMS). Herein, we first studied the unique fragmentation behavior of phenanthrenes based on direct infusion MS/HRMS analysis.

Article Synopsis
- Phenanthrenes, rare compounds found in certain plant families, show diverse pharmacological activities, prompting research into their semisynthetic derivatives.
- This study aimed to isolate phenanthrenes from a specific methanolic extract and develop semisynthetic derivatives, successfully isolating three phenanthrenes and producing four new compounds using hypervalent iodine(III) reagents.
- The isolated compounds and their derivatives were tested against various human tumor cell lines, with one effusol derivative exhibiting significant antiproliferative effects, especially against MCF-7, T47D, and A2780 cell lines.
