    Kojic acid (Standard)
    Kojic acid (Standard) is the analytical standard of Kojic acid. This product is intended for research and analytical applications. Kojic acid is a substance produced by Aspergillus oryzae, with various biological activities including antitumor, insecticidal, antibacterial, antioxidant, and radioprotective effects. Kojic acid exhibits tyrosinase inhibition activity by capturing copper ions that bind to the active site of tyrosinase, preventing its activation. Tyrosinase is a key enzyme in the biosynthesis of melanin, so kojic acid can block melanin production. Additionally, kojic acid shows potential inhibition of NF-κB activity in human keratinocytes, which may also be related to the anti-melanogenic effect induced by kojic acid. Kojic acid is effective when administered orally and can also be absorbed transdermally. Nano-carrier systems prepared with kojic acid demonstrate effective delivery of anticancer drugs. Kojic acid holds promise for research in cancer, infectious diseases, and skin whitening among other fields.
