Background:

Avobenzone-¹³C-d₃is intended for use as an internal standard for the quantification of avobenzone by GC- or LC-MS. Avobenzone is a full-spectrum ultraviolet A (UVA) blocker.¹It inhibits UVA-induced increases in melanin levels and tyrosinase activity in B16/F10 melanoma cells (IC₃₀s = 21.94 and 24.25 μM, respectively).²Avobenzone (30 μM) also inhibits UVA-induced production of reactive oxygen species (ROS) and 8-hydroxy-2'-deoxyguanosine , as well as inhibits UVA-induced depletion of glutathione (GSH), in B16/F10 cells. It increases nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and upregulates the antioxidant response element (ARE) in UVA-irradiated B16/F10 cells when used at at a concentration of 30 μM. Formulations containing avobenzone have been used as sun protectants in sunscreen products.
