General description

1-Naphthol is a hydroxyl-aromatic compound. Its thermodynamic properties such as heat capacity, sublimation pressure, vapor pressure, enthalpies of combustion, formation and fusion have been estimated.

Application

1-Naphthol is used as a biomarker for exposure to polycyclic aromatic hydrocarbons (PAHs) in humans and livestock. 1-Naphthol is suitable for detecting the presence of carbohydrates and in various reactions.

In vitro glucuronidation assays of diclofenac and indomethacin at pH 7.4 are biased by the instability of the glucuronides due to acyl migration. The extent of this acyl migration may be reduced significantly by performing the glucuronidation reaction at pH

UDP-glucuronic acid binds first and the aglycone substrate binds second to form a ternary complex in UGT1A9-catalyzed reactions, in both the presence and absence of bovine serum albumin.

Nenad Manevski et al.

Drug metabolism and disposition: the biological fate of chemicals, 40(11), 2192-2203 (2012-08-23)

The presence of bovine serum albumin (BSA) largely modulates the enzyme kinetics parameters of the human UDP-glucuronosyltransferase (UGT) 1A9, increasing both the apparent aglycone substrate affinity of the enzyme and its limiting reaction velocity (Drug Metab Dispos 39:2117-2129, 2011). For
