Alternative electron carrier in the mitochondrial electron transport chain. Bypasses Complex I and III dysfunction by shuttling electrons directly to Complex IV (cytochrome c oxidase). Also inhibits tau aggregation, monoamine oxidase, and nitric oxide synthase. Hormetic — low doses are beneficial, high doses are toxic.
Triple incretin agonist (GIP/GLP-1/glucagon receptor). Combines appetite suppression and insulin sensitization of GLP-1 with the thermogenic and lipolytic effects of glucagon receptor activation. Produced the greatest weight loss of any anti-obesity agent in Phase 2 trials (~24% at 48 weeks).
