Calpinactam (CAS 1205538-83-5)

Calpinactam is a synthetic compound known for its activity as a calpain inhibitor. Calpains are a family of calcium-dependent, non-lysosomal cysteine proteases involved in various cellular functions, including cell motility, cell cycle progression, and apoptosis. These enzymes play a critical role in intracellular signaling pathways, modulating the turnover and function of many regulatory proteins. As a calpain inhibitor, Calpinactam interacts with the active site of calpain, preventing its proteolytic activity. This inhibition is crucial for studies investigating the pathological processes where calpain is implicated, such as neurodegenerative diseases, ischemia, and muscle wasting disorders. By blocking calpain activity, Calpinactam helps to preserve cellular integrity and function, providing a valuable tool for research into calpain′s roles in disease and health. The development and use of Calpinactam primarily revolve around its potential to modify disease progression in conditions where excessive or unregulated activation of calpain contributes to cellular damage and dysfunction. This makes it a compound of interest not only for basic biochemical research but also for potential therapeutic applications aimed at diseases involving dysregulated protease activity.
