Tesofensine peptide molecular structure diagram from PubChem

Tesofensine is a novel triple monoamine reuptake inhibitor (serotonin, norepinephrine, dopamine) originally developed for neurodegenerative diseases that demonstrated significant weight loss effects in clinical trials. It reduces appetite and increases metabolic rate through central nervous system mechanisms.
