Physcion, a novel inhibitor of 5α-reductase that promotes hair growth in vitro and in vivo
Archives of Dermatological Research, 2021Androgenic alopecia (AGA) has a high incidence. Excess dihydrotestosterone in blood capillaries, which is converted from testosterone by 5α-reductase, is an AGA causative factor. We identified the inhibitory activity of four Polygonum multiflorum compounds against 5α-reductase via high-performance liquid chromatography, and the results showed that ...

In Vitro and in Vivo Studies of the Electrophilicity of Physcion and its Oxidative Metabolites
Chemical Research in Toxicology, 2018Physcion (1,8-dihydroxy-3-methoxy-6-methyl-9,10-anthracenedione) is a bioactive component found in Polygoni Multiflori Radix (PMR), which has been widely used as traditional Chinese medicine. Unfortunately, studies showed hepatotoxicity of PMR during its clinical use. The mechanisms of its toxic action remain unknown. The major objectives of this study

Rapid adsorption and enhanced removal of emodin and physcion by nano zirconium carbide
Science of The Total Environment, 2019In this study, nano zirconium carbide (n-ZrC) was synthesized by preceramic polymers method, and it was used to adsorb emodin and physcion from solutions for the first time. The prepared material was characterized by various technologies. The adsorption experiment was carried out to investigate the emodin and physcion removal performance.

A novel electroanalytical method for the determination of physcion is described for the first time. Physcion yields an adsorption catalytic voltammetric peak at −0.74 V (vs. SCE) in 0.4 mol L−1 NH4Cl–NH3·H2O buffer solution (pH 10.5) at a carbon paste electrode (CPE).

Colloids and Surfaces B: Biointerfaces, 2019
In this study, we have encapsulated natural physcion (PHY) drug loading into metal-organic frameworks MOFs, zeolitic imidazolate frameworks (ZIFs) through straight-forward nano-precipitation technique. The synthesized PHY@ZIF-8 indicated high drug loading encapsulation efficiency i.e. 88%, whereas, drug loading capacity was found to be 11.49%.

AbstractThe electrochemical chlorination of physcion (=1,8‐dihydroxy‐3‐methoxy‐6‐methylanthracene‐9,10‐dione; 1) in AcOH and CH2Cl2 was investigated by cyclic voltammetry and prep.‐scale electrolysis. This approach provided access to a number of diverse biologically and pharmacologically interesting chlorinated secondary metabolites of lichen.
