Characterization of the superoxide anion radical scavenging activity by tetracycline antibiotics in aprotic media.

ABSTRACT The tetracycline family antibiotics are widely used as human and veterinary treatments. The drugs are effective as antibiotics and also show antimicrobial and non-microbial action. However, the antioxidant properties of tetracyclines have not been characterized in aprotic media. To better understand their biological functions, the in vitro superoxide anion radical ( [ABSTRACT FROM AUTHOR]
