Biological target:

Rhododendrol competes with tyrosine for hydroxylation by tyrosinase and interferes with melanin synthesis. First, rhododendrol is catalysed by tyrosinase to produce toxic metabolites as rhododendrol-cyclic catechol. These reactive metabolites cause damage to the melanocytes.

In vitro activity:

Rhododendrol-induced leukoderma is an autoimmune disorder, with rhododendrol as an environmental factor and HLA-DR4 as a genetic factor. Rhododendrol might be effective in treating melanomas. References: . Dermatology. 2016;232(1):44-9. https://pubmed.ncbi.nlm.nih.gov/26613259/

In vivo activity:

Mice supplemented with rhododendrol have dramatically altered hepatic metabolisms concurrent with shifts in specific gut bacteria. Reference: Food Funct. 2022 Dec 13;13(24):13052-13063. https://pubmed.ncbi.nlm.nih.gov/36468583/
