Common Name

2-hydroxychromene-2-carboxylic acid

Description

2-hydroxychromene-2-carboxylic acid is a member of the chromene class of compounds, characterized by its bicyclic structure containing a benzene ring fused to a pyran ring, with a hydroxyl and a carboxylic acid functional group. This compound plays a role in the naphthalene catabolic pathway, particularly in Pseudomonas putida, where it is involved in the enzymatic interconversion mediated by the enzyme 2-hydroxychromene-2-carboxylic acid isomerase. This enzyme catalyzes the glutathione (GSH)-dependent conversion of 2-hydroxychromene-2-carboxylic acid and trans-o-hydroxybenzylidene pyruvic acid, indicating its significance in metabolic processes (PMID:17508726 ). Additionally, the oxidation of 1,2-dihydroxynaphthalene by purified 1,2-dihydroxynaphthalene oxygenase leads to the formation of 2-hydroxychromene-2-carboxylic acid, suggesting its derivation from enzymatic transformations within metabolic pathways (PMID:7204331 ). The compound's formation from ring fission products further illustrates its role in the complex biochemical pathways associated with naphthalene metabolism (PMID:985513 ).
