Radical scavenging effects of 1-naphthol, 2-naphthol, and their sulfate-conjugates

The Journal of Toxicological Sciences, 2018
1-Naphthol (1-Nap) and 2-naphthol (2-Nap) are phenolic isomers that may be subjected to sulfate conjugation in vivo. Phase-II sulfate conjugation of phenolic compounds is generally thought to result in their inactivation. This study aimed to investigate the antioxidative effects of 1-NapS and 2-NapS, in comparison with their unsulfated counterparts ...

5-Amino-1-naphthol [PDF]

Acta Crystallographica Section E Structure Reports Online, 2009
In the title compound, C(10)H(9)NO, the amino and the hydr-oxy groups act both as a single donor and a single acceptor in hydrogen bonding. In the crystal, mol-ecules are connected via chains of inter-molecular ⋯N-H⋯O-H⋯ inter-actions, forming a two-dimensional polymeric structure resembling the hydrogen-bonded mol-ecular assembly found in the crystal ...
