Science
Mechanism of Action
The proposed mechanism of KADSURA JAPONICA BRANCH/FRUIT/LEAF EXTRACT, inferred from studies on the Kadsura genus and Kadsura coccinea, involves multi-targeted action. Its anti-melanogenic effects are likely achieved by reducing the protein and mRNA expression of key enzymes like tyrosinase, tyrosinase-related protein-1 (TRP-1), and tyrosinase-related protein-2 (TRP-2). This action is further supported by the downregulation of myophthalmosis-related transcription factor expression and inhibition of cAMP-related binding protein phosphorylation. Additionally, the extract demonstrates potential photoprotective activity by enhancing keratinocyte viability and mitigating intracellular reactive oxygen species (ROS) production and apoptosis triggered by UVA and UVB irradiation. Lignans and triterpenoids are considered primary bioactive constituents contributing to its antioxidant and anti-inflammatory activities.
