Definitions

  • the present invention relates to a novel benzamide derivative compound, a preparation method thereof and a pharmaceutical composition using the same as an active ingredient.
  • 5-HT 4 receptor agonists can be used for various diseases, including reflux esophagitis, gastrointestinal disorders, gastrointestinal disorders, non-ulcer dyspepsia, functional dyspepsia, irritable bowel syndrome (IBS), constipation, indigestion, esophagitis, gastritis It has been shown to be useful in the treatment of degree disease, motion sickness, central nervous system disease, Alzheimer's disease, cognitive impairment, vomiting, migraine, neurological disease, pain, cardiovascular disorders, heart failure, deep vein, diabetes and apnea syndrome (Tips, 1992, 13, 141; Ford APDW et al., Med. Res. Rev., 1993, 13. 633; Gullikson GW et al., Drug Dev.
  • IBS irritable bowel syndrome
  • Cisapride a representative 5-HT 4 receptor agonist
  • Cisapride is one of the benzamide derivatives, the origin of which is metocloprid
  • US Pat. Nos. 4,962,115, 5,057,525 and 5,137,896 are N- (3-hydroxy including cisapride 4-piperidinyl) benzamide is disclosed. These compounds are known to stimulate gastrointestinal motility.
  • Benzamide derivatives have several excellent pharmacological actions.
  • the superior pharmacological action of benzamide derivatives is due to their effect on the nervous system regulated by the neurotransmitter serotonin.
  • the role of serotonin, the pharmacological action of benzamide derivatives has been extensively studied in various diseases for many years.
  • research has been focused on the production and storage of serotonin, as well as on the location of serotonin receptors in humans to determine the correlation between various disease states or diseases.
  • Benzamide derivatives increase gastrointestinal smooth muscle activity from the esophagus to the adjacent small intestine, accelerating esophagus and small intestinal movement, emptying the stomach and increasing esophageal sphincter tension (Decktor et al., Eur. J. Pharmacol. 147: 313-316, 1988).
  • Benzamide derivatives are not cholinergic receptor agonists, but the aforementioned smooth muscle effect can be blocked by muscarinic receptor blockers such as atropine or neurotransmitter inhibitors such as tetrodotoxin that block sodium channels.
  • the small intestine has been reported to show similar blocking activity on the contractile effects of serotonin.
  • benzamide derivatives on smooth muscle is the 5-HT 4 receptor located on interneurons in the myenteric plexus of the gut wall. It has been reported to act as an agonist on serotonin receptors and to show excellent activating effects on smooth muscle. Activation of these receptors subsequently enhances the release of acetylcholine from parasympathetic nerve terminals located around smooth muscle fibres. This is the combination of acetylcholine and its receptor on the smooth muscle membrane that actually causes muscle contraction.
  • Cisaprid cures reflux esophagitis (GERD) by inhibiting gastrointestinal contents from reflux into the esophagus.
  • GFD reflux esophagitis
  • One of the most important factors in the pathogenesis of reflux esophagitis is the lowering of the pressure barrier due to loss of function of the subesophageal sphincter. Malfunction of the lower esophageal sphincter is caused by low basal pressure, sphincter relaxation, and a non-compensated increase in gastric internal pressure.
  • Other pathogenesis factors include delayed emptying of the stomach, insufficient emptying of the esophagus due to impaired peristalsis, and corrosiveness of reflux substances that damage the esophageal mucosa.
  • Cisaprid is expected to increase esophageal sphincter pressure and improve esophageal passage.
  • Cisapride may be usefully used to treat indigestion, gastrointestinal discomfort, postoperative ileus, and pseudo ileus because of its activity as a prokinetic substance.
  • Indigestion is a symptom mainly of gastrointestinal dysfunction, which is also a disease characterized by impaired digestive or digestive function that can result from complications from other diseases such as appendicitis, gallbladder disorders or malnutrition.
  • Gastric disability refers to gastrointestinal paralysis due to gastric dyskinesia or complications of diseases such as diabetes mellitus, progressive systemic sclerosis, anorexia nervosa or dystonia.
  • Constipation is a disease characterized by infrequent or difficult excretion due to diseases caused by intestinal muscle tension or lack of stiffness.
  • Postoperative intestinal obstruction is an intestinal obstruction caused by the destruction of muscle tension following surgery.
  • False ileus is a symptom characterized by constipation, abdominal pain and vomiting, but there is no evidence of physical obstruction.
  • cisapride When cisapride was administered to humans, serious side effects were found, including CNS disorders, elevated blood pressure, interaction with other drugs, diarrhea and abdominal cramps. In addition, intravenous administration of cisapride resulted in additional adverse events that were not present in oral administration (Stacher et al. 1987 Digestive Diseases and Sciences 31 (11): 1223-1230). The causes of these side effects are known to be metabolites from the oxidative dealkylation or aromatic hydrolysis of compounds occurring in the P450 detoxification system. Cisapride is also susceptible to numerous undesirable drugs or drug interactions, which are also metabolic consequences of the cytochrome P450 system.
  • the stability of 5-HT 4 receptor agonists with prokinetic motility in the gastrointestinal tract is influenced by adverse effects of the drug due to cardiac effects (extending QT interval, cardiac arrest, ventricular arrhythmias) and liver cytochrome P450 metabolism. It has been limited. Gastrointestinal prokinetic drugs that do not have this disorder would be invaluable for diseases such as reflux esophagitis and gastric emptying disorders.
  • Several derivatives of cisaprid are described by US Pat. No. 6,552,046 and World Patent 01/093849, but many are required for compounds.
