Description: Kojic Acid is a tyrosinase inhibitor. It is a chelation agent produced by several species of fungi, especially Aspergillus oryzae, which has the Japanese common name koji. It is a mild inhibitor of the formation of pigment in plant and animal tissues, and is used in food and cosmetics to preserve or change colors of substances. It also appears to possess marked protective (radioresistance) effects from radiation-induced damage.

Bulk inquiry Welcome, Customer: Please do not inquire quote if your intended use is for a patient since our products are for research use and for chemical synthesis use, not for human use . For in-stock products, we listed price in the web page. You may inquire prices for which sizes were not listed. If no price is listed, this means the product is not in stock at the moment, which may be available via custom synthesis. For cost-effective reason, minimum order of 1g is requested (typically very expensive). The lead time is usually 2-4 months. Quote of less than 1g will not be provided. MedKoo may not offer quote for below reasons: (1) current available synthetic method appears to be extremely expensive which is obviously not affordable to most customers; (2) Key raw material to make the product is temporally not available; (3) DEA controlled substances; (4) the product is under patent protection in customer’s country.

Biological target:	Kojic Acid is a tyrosinase inhibitor.
In vitro activity:	In addition, kojic acid could alleviate HUVEC tube formation induced by senescent HCEC, which could be reversed by p-NF-κB inhibitor. The p21 siRNA could alleviate HUVEC spheroid sprouting induced by senescent HCEC. These results indicated that kojic acid might inhibit HCEC senescence and following resulted angiogenesis via NF-κB and p21 signaling pathways, possibly through downregulation of galectin 8 and laminins. Reference: Exp Eye Res. 2019 Mar;180:174-183. https://pubmed.ncbi.nlm.nih.gov/30597146/
In vivo activity:	The results from the cytotoxicity and cell viability assays demonstrated that KA (kojic acid) could highly protect Chinese hamster ovary (CHO) cells against ionizing radiation with low toxicity. In summary, KA provides marked radioprotective effects both in vivo and in vitro. Reference: Asian Pac J Cancer Prev. 2014;15(1):291-7. https://pubmed.ncbi.nlm.nih.gov/24528043/
