General description

Amlexanox is an anti-allergic drug with anti-inflammatory properties.

Biochem/physiol Actions

Amlexanox elevates the amount of nonsense-containing mRNAs in treated cells and helps to generate full-length proteins effectively.
Amlexanox is an anti-allergy and anti-asthma drug that blocks histamine and leukotriene release from leukocytes and mast cells. Amlexanox has also been shown to inhibit cahaperone activity of Hsp90, and S100A13, which is involved in transport of proteins devoid of signal peptide sequences.
