  • the present invention relates to novel compounds and uses thereof, and more particularly to novel compounds for PET imaging and uses thereof.
  • Coronary artery disease accounts for 3-4 of the causes of death in Korea. In particular, the prevalence has increased nearly five times over the past two decades, and this will accelerate further in the global trend. Symptoms of coronary artery disease appear mainly after 45-50 years of age, but the prevalence of coronary artery disease has increased in recent years, and the number of cases with symptoms in younger patients has been increasing, and the importance of early diagnosis and prevention is gradually increasing.
  • Coronary artery disease is diagnosed early by methods of exercise testing, echocardiography, coronary angiography, and nuclear medicine.
  • exercise testing may not reveal any abnormality when examined in a stable state with no symptoms in angina pectoris.
  • Echocardiography can not reliably calculate the size or function of heart if it does not completely contain the heart. There is a drawback that it takes much time to see.
  • coronary angiography can cause complications such as death or acute myocardial infarction at less than 0.1%, so it can not be applied to all patients suspected of angina.
  • the nuclear medicine method used is single photon emission computed tomography (SPECT).
  • SPECT single photon emission computed tomography

  • the present inventors have developed a contrast agent for PET containing 18 F based on tetraphenylphosphonium (TPP) salt (Patent No. 1172157).
  • the TPP salt-based contrast agent for PET has a problem in that it has a low cardiac selectivity and a high uptake rate in bones, as well as a problem in heart image analysis due to a high uptake rate in the liver adjacent to the heart.
