Chemical Structure
Kojic acid
- CAS No.: 501-30-4
- Formula:C6H6O4
- Molecular Weight:142.11
IUPAC Name: 5-hydroxy-2-(hydroxymethyl)-4H-pyran-4-one
InChIKey: BEJNERDRQOWKJM-UHFFFAOYSA-N
SMILES: O=C1C=C(CO)OC=C1O
Biological Activity: Kojic acid is a substance produced by Aspergillus oryzae that is orally effective and can also be absorbed transdermally. Kojic acid exhibits various biological activities, including anti-aging, anti-nematode, antimicrobial, antioxidant, and anti-inflammatory effects. Kojic acid is a Tyrosinase inhibitor with an Mushroom Tyrosinase IC50 of 182.7 μM. Kojic acid prevents melanin production by capturing copper ions that bind to the tyrosinase active site, thus inhibiting its activation. Kojic acid also suppresses the NF-κB and p21 signaling pathways in human keratinocytes. Kojic acid derivatives have anticancer activity[1][2][3][4][5][6][7][8].

Kojic acid (Standard) | ≥98% | 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. | ||||||||||||||||||||
