ICI 153110 is primarily used in research settings to study its effects on biological systems, particularly in the field of pharmacology. It has been investigated for its potential as an antiarrhythmic agent, which means it could help regulate irregular heartbeats. Researchers have explored its ability to interact with ion channels in cardiac cells, which play a critical role in maintaining normal heart rhythm. Additionally, it has been studied for its possible neuroprotective properties, suggesting it might help protect nerve cells from damage in certain conditions. While its applications are still largely experimental, it serves as a valuable tool for understanding the mechanisms of heart function and neurological health.
