Chemical investigations and cytotoxic effects of metabolites from Antrodia camphorata against human hepatocellular carcinoma cells

Evidence-Based Nutraceuticals Derived from Antrodia cinnamomea

Antrodia cinnamomea (A. cinnamomea), a medicinal and edible mushroom endemic to Taiwan, has been traditionally valued as a health tonic. Recent studies have highlighted the diverse specialized metabolites and bioactive potential of this substance, primarily attributed to key secondary metabolites such as benzenoids, maleic and succinic acids, ubiquinone, triterpenoids, and the primary metabolite polysaccharides. These compounds exhibit a broad spectrum of pharmacological properties, including those related to antibacterial, antitumor, anti-inflammation, hepatoprotection, hypoglycaemia, and antioxidant activities, and immunomodulation and gut microbiota regulation. These findings highlight the therapeutic potential of A. cinnamomea and its potential applications in health supplements and functional foods. This review evaluated recent advancements in the cultivation, extraction, and characterization of bioactive compounds from A. cinnamomea, with a particular focus on submerged and solid-state fermentation methods. We hope to provide a comprehensive framework for promoting the efficient and scientific evidence based utilization of A. cinnamomea in novel therapeutic strategies and health-related innovations.

Discovery of 5-Hydroxy-1,4-naphthoquinone (Juglone) Derivatives as Dual Effective Agents Targeting Platelet-Cancer Interplay through Protein Disulfide Isomerase Inhibition

In this study, a series of 2- and/or 3-substituted juglone derivatives were designed and synthesized. Among them, 9, 18, 22, 30, and 31 showed stronger inhibition activity against cell surface PDI or recombinant PDI and higher inhibitory effects on U46619- and/or collagen-induced platelet aggregation than juglone. The glycosylated derivatives 18 and 22 showed improved selectivity for inhibiting the proliferation of multiple myeloma RPMI 8226 cells, and the IC50 values reached 61 and 48 nM, respectively, in a 72 h cell viability test. In addition, 18 and 22 were able to prevent tumor cell-induced platelet aggregation and platelet-enhanced tumor cell proliferation. The molecular docking showed the amino acid residues Gln243, Phe440, and Leu443 are important for the compound-protein interaction. Our results reveal the potential of juglone derivatives to serve as novel antiplatelet and anticancer dual agents, which are available to interrupt platelet-cancer interplay through covalent binding to PDI catalytic active site.

Triterpene acid from Antrodia camphorata alleviates inflammation in acute liver injury

This study aimed to investigate the role and mechanism of Anctin A, the Antrodia camphorata terpene component, in resisting liver injury. Network pharmacology analysis revealed that MAPK3 was the major action target of Antcin A. Furthermore, experimental research suggested that Antcin A suppressed mouse liver injury, reduced the inflammatory factor levels, and enhanced the anti-oxidative capacity. Meanwhile, it suppressed the expression of MAPK3 and the downstream NF-κB signal, while it did not significantly affect the expression of MAPK1. Based on network pharmacology method, this study discovers that the anti-liver injury effect of Antcin A is mainly related to MAPK3, and that Antcin A can suppress the activation of MAPK3 and its downstream NF-κB to inhibit mouse ALI.
