PK-THPP is primarily utilized in research and development within the field of neuroscience, particularly in the study of potassium channels. These channels play a critical role in regulating electrical activity in cells, especially in neurons. PK-THPP acts as a potent and selective inhibitor of certain types of potassium channels, making it a valuable tool for understanding their function and behavior in various physiological and pathological conditions. Its application extends to investigating conditions such as epilepsy, cardiovascular diseases, and other disorders where potassium channel dysfunction is implicated. Additionally, PK-THPP is used in pharmacological studies to explore potential therapeutic targets and to develop new drugs targeting potassium channels. Its specificity and efficacy make it a key compound in advancing knowledge in cellular electrophysiology and drug discovery.
