FCE 28654 is primarily utilized in the field of medical research, particularly in the study of cardiovascular diseases. It functions as a selective inhibitor, targeting specific pathways involved in the regulation of blood pressure and vascular tone. This makes it a valuable tool for understanding the mechanisms underlying hypertension and related conditions. Additionally, it has been explored for its potential therapeutic applications in managing heart failure, as it helps in reducing the workload on the heart and improving overall cardiac function. Researchers also investigate its role in protecting against vascular damage caused by oxidative stress, which is crucial in preventing long-term complications in patients with chronic cardiovascular issues.
