    Aldehyde trapping by ADX-102 is protective against cigarette smoke and alcohol mediated lung cell injury.
    Bailey KL ;
    Bauer CD
    2022/03/02 | National Institute for Occupational Safety and Health (NIOSH)
    Most individuals diagnosed with alcohol use disorders smoke cigarettes. Large concentrations of malondialdehyde and acetaldehyde are found in lungs co-exposed to cigarette smoke and alcohol. Aldehydes directly injure lungs and form aldehyde protein adducts, impacting epithelial functions. Recently, 2-(3-Amino-6-chloroquinolin-2-yl)propan-2-ol (ADX- ...
