Abstract

The present invention provides compounds useful as inhibitors of Ca2+ / calmodulindependent protein kinase (CaMKII), compositions thereof, and methods of using the same. Cardiovascular disease remains the number one cause of death in developed countries. Furthermore, incidence of cardiovascular disease has increased dramatically in developing countries. Although cardiovascular disease usually affects older adults, the antecedents of cardiovascular disease, notably atherosclerosis, begin in early life, making primary prevention efforts necessary from childhood.

Description

Background technique [0001] Cardiovascular disease remains the number one cause of death in developed countries. In addition, the incidence of cardiovascular disease is significantly higher in developing countries. Although cardiovascular disease generally affects older adults, the precursors to cardiovascular disease, especially atherosclerosis, begin in early life, necessitating primary prevention starting at an early age. Therefore, prevention of atherosclerosis has received increased attention by modifying risk factors such as healthy diet, exercise and avoidance of smoking. It is estimated that 1 in 3 people die from complications caused by cardiovascular disease. "Global Atlason Cardiovascular Disease Prevention and Control," World Health Organization, January 2012. To arrest this trend and address the metastatic epidemiology of the disease, measures to prevent or reverse cardiovascular disease must be implemented. [0002] Obesity and diabetes are often associated w...
