Development of flavanone and its derivatives as topical agents against psoriasis: The prediction of therapeutic efficiency through skin permeation evaluation and cell-based assay.

Flavonoids inhibit skin inflammation. Previous study suggests that the flavonoids with flavanone backbone were beneficial to penetrate into the skin. We aimed to investigate the possibility of psoriasis treatment by topically applied flavanone and its derivatives including naringenin, hesperetin, 6-hydroxyflavanone, flavanone, and 6-bromoflavone.
