chrysin and Skin-Diseases

Chrysin belongs to the group of natural polyphenols. It can be found, among others, in honey, propolis and fruits and has a wide range of biological activities, including the prevention of oxidative stress, inflammation, neurodegeneration and carcinogenesis. Being a part of the human diet, chrysin is considered to be a promising compound to be used in the prevention of many diseases, including cancers, diabetes and neurodegenerative diseases such as Alzheimer's or Parkinson's. Nevertheless, due to the low solubility of chrysin in water and under physiological conditions, its bioavailability is low. For this reason, attempts at its functionalization have been undertaken, aiming to increase its absorption and thus augment its in vivo therapeutic efficacy. The aim of this review is to summarize the most recent research on chrysin, including its sources, metabolism, pro-health effects and the effects of its functionalization on biological activity and pharmacological efficacy, evaluated both in vitro and in vivo.

Amiodarone is the first choice for the treatment of arrhythmia, but it is easy to cause extravasation during infusion, after extravasation, it often cause skin injury. The healing of skin injury induced by amiodarone is an inflammatory process. Chrysin, a natural flavonoid, has been investigated to have anti-inflammatory and antioxidant effects. It was reported that chrysin can promote wound healing. So this study aims to investigate the effect of chrysin on amiodarone extravasation-induced skin injury model in rats.. The rat model of skin extravasation injury was established by subcutaneous injection of 0.5 mL of amiodarone. After successful modeling, the rats were randomly assigned to the five groups: control group, 10% DMSO group, and low-dose, medium-dose, and high-dose chrysin groups (10, 20 and 40 mg/mL). The extravasation injury model was given locally on the same day for seven days. On day 0, 3, 7 and 10 of administration, the lesion's image were taken to calculate the area, and the tissue of the lesion were collected for H&E staining. Then, the level of IL-6 and TNF-α were measured by ELISA, and the protein expression level of bFGF in the wound tissue were detected by immunohistochemical staining.. It was found that chrysin groups (20 and 40 mg/mL) compared to contronl group and 10% DMSO solvent group significantly decreased area injury, IL-6 and TNF-α(P < 0.05) on day 3, 7, 10. On the other hand, the chrysin group (40 mg/mL) compared to contronl group and 10% DMSO group significantly increase bFGF(P < 0.05) on day 3, 7.. Chrysin were effective in reducing injury area, reducing inflammation, and promoting the secretion of bFGF, it can promote the healing of skin injury induced by amiodarone extravasation in rats. These findings provide a good theoretical and experimental basis for the prevention and treatment of amiodarone extravasation-induced skin injury, and provide evidence for finding potential healing agents for the prevention and treatment of amiodarone and other corrosive extravasation-induced injuries from the molecular and cytological levels, thus solving the clinical problems.
