Description Research Excerpts Clinical Trials Roles Classes Pathways Study Profile Bioassays Related Drugs Related Conditions Protein Interactions Research Growth Market Indicators

Calpeptin is a natural product that has been isolated from the fungus *Calvatia gigantea*. It is a potent and selective inhibitor of the enzyme calpain, which is a cysteine protease involved in a variety of cellular processes, including muscle contraction, cell signaling, and apoptosis. Calpeptin has been shown to have anti-inflammatory, anti-cancer, and neuroprotective effects in animal models. Calpeptin is being studied for its potential therapeutic applications in a variety of diseases, including cancer, Alzheimer's disease, and stroke. Its potential applications in treating various diseases make it an important subject of study.'

Calpeptin was found to be a useful cell-penetrative calpain inhibitor.

Treatment

Calpeptin treatment of MDCK cells resulted in a displacement of zonula occludens-1 (ZO-1) from cell-cell junctions. Pretreatment with calpeptin attenuated glial activation, T cell infiltration, nigral dopaminergic degeneration in SN, and neuronal death in spinal cord. Calpeptin pretreatment restored miRNA levels in hyperglycaemic MKs.
