Definitions

  • This invention relates to novel propanolamine derivatives, which have useful therapeutic properties in the field of medicinal chemistry, and is particularly concerned with 3-phenoxy-l-phenoxyalkylamino-Z- propanols, in which the phenyl group of the l-substituent carries an electron-withdrawing polar substituent, and analagous compounds in which one or other of the phenyl groups is replaced by a naphthyl group. More particularly the compounds of the invention are useful in the curative or prophylactic treatment of cardiac conditions, such as angina pectoris and cardiac arrhythmias, and in the treatment of hypertension.
  • Angina pectoris and cardiac arrhythmias are due to interference with the blood supply to the heart muscle.
  • drugs have been sought which would improve the blood supply and most work has concentrated on attempts to dilate the coronary arteries. More recently, efforts have been made to find drugs which will block the B-adrenergic receptors in heart muscle and thus prevent over stimulation of the heart.
  • The'heart muscle is directly influenced by nervous system stimuli substances or catecholamines (e.g. adrenaline, non-adrenaline, and isoprenaline) which affect body organs such as the heart by attaching themselves to receptors which are specialized areas of the cell membranes.
  • catecholamines e.g. adrenaline, non-adrenaline, and isoprenaline
  • the fl-adrenergic receptors are concerned in the stimulation of heart muscle, and the compounds of this invention exhibit a tendency to block B-adrenergic receptors and reduce the effect of the nervous system catecholamines on the heart.
