Leupeptin is a reversabile protease inhibitor known to target various cathepsins, calpain and trypsin. In biochemical research, leupeptin is used frequently as a reducing agent in experiments designed to study proteins, enzymes, amino acids and neuropeptides.ApplicationsWhile it is used widely as a reagent, several studies have been conducted into leupeptin's direct biomedical effects. In one such study, leupeptin was shown to protect hair cells in the inner ear from ototoxicity associated with aminoglycoside antibiotic treatment. In rat studies, leupeptin has demonstrated a considerable ability to suppress inflammation caused by gingivitis.CAS Number: 103476-89-7Molecular Weight: 951.2 DaChemical Formula: C40H78N12O12SSolubility: Soluble in water (50 mg/mL), clear and colorless to faint yellow solutionStorage Temperature: -20CResearch or further manufacturing use only, not for food or drug use.
