Stability of Hemoglobin and Albumin Adducts of Naphthalene Oxide, 1,2-Naphthoquinone, and 1,4-Naphthoquinone [PDF]

Toxicological Sciences, 2002
Naphthalene is an important industrial chemical, which has recently been shown to cause tumors of the respiratory tract in rodents. It is thought that one or more reactive metabolites of naphthalene, namely, naphthalene-1,2-oxide (NPO), 1,2-naphthoquinone (1,2-NPQ), and 1,4-naphthoquinone (1,4-NPQ) contribute to the tumorigenicity of this chemical ...

Two Novel 1,4‐Naphthoquinone Derivatives as Potent Agents Against Multidrug‐Resistant Staphylococcus aureus and Pathogenic Gram‐Positive Bacteria

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT Drug‐resistant bacteria such as Methicillin‐resistant Staphylococcus aureus (MRSA) and Quinolone‐resistant S. aureus (QRSA), are a growing problem, creating a need for the development of novel antimicrobial agents. In this study, we designed and synthesized two novel 1,4‐naphthoquinone derivatives, LHN‐1034 and LHN‐1035, and evaluated their ...
