Scavenging of reactive oxygen species by N-substituted indole-2 and 3-carboxamides.

Indole-2 and 3-carboxamides (IDs) are proposed to be selective cyclooxygenase inhibitors. Since cyclooxygenase-1 may be involved in reactive oxygen species (ROS) production, we hypothesize that these indole derivatives have antioxidative properties. We have employed chemiluminescence (CL) and electron spin resonance (ESR) spin trapping to examine this hypothesis.
