Definitions
- the present invention is directed to an improved pharmaceutical formulation containing Epipitolipinolide and Costunolide extracted from the bark of a lily tree. More specifically, the present invention relates to a pharmaceutical formulation for treating the gastrointestinal tract, which contains epiturifinolide and costunide as active ingredients of the extract of the bark of a lily tree.
- Gastritis and gastric ulcers are the most frequent diseases of the digestive system, with about 10% of Korea's population experiencing at least once in their lifetime.
- the gastric wall (gastric wall is composed of mucosal layer, submucosa, muscle layer, and membrane) is located in the stomach acid.
- gastritis is a state in which the mucosa is damaged
- gastric ulcer is a case in which the submucosa or muscle layer is damaged.
- the cause of gastritis and gastric ulcers is known to be caused by the imbalance between the attack and defense factors, that is, the increase of the attack factors or the weakening of the defense factors.
- Factors that increase the attack factor include increased acid and pepsin secretion.
- Factors that weaken the defense factor include deficits in the structure and form of the gastric mucosa, decreased mucus secretion, decreased bicarbonate ion secretion, and decreased prostaglandin production. For example, it is known that gastric ulcers are also caused by infection of Helicobacter pylori.
- gastric ulcer development is the excessive secretion of gastric acid, which is a hydrochloric acid secreted by gastric wall cells, which activates pepsin to decompose proteins as well as lethal action on damaged gastric walls.
- gastric acid which is a hydrochloric acid secreted by gastric wall cells, which activates pepsin to decompose proteins as well as lethal action on damaged gastric walls.
- Currently used therapeutic agents for gastritis and gastric ulcer are classified into drugs that inhibit attack factors such as gastric acid, pepsin, smoking, oxygen free radicals, and alcohol, and drugs that enhance defense factors according to pathophysiology.
- Attack inhibitors include gastric acid secretion inhibitors such as antacids, H2 receptor antagonists (Cimetidine, Ranitidine, Famotidine, etc.), and Proton pump inhibitors (PPI: Omeprazole, Lansoprazole, etc.).
- gastric acid secretion inhibitors such as antacids, H2 receptor antagonists (Cimetidine, Ranitidine, Famotidine, etc.)
- PPI Proton pump inhibitors
- Protective agent enhancers protect the gastric mucosa by inducing ulcer lesion coating, promoting mucus synthesis and secretion, increasing gastric mucosa, increasing endogenous prostaglandin, and increasing tissue regeneration, depending on the type of protective factor enhancer. There is a mechanism of action and these are known to be particularly useful in preventing ulcer recurrence. H. Pylori eradication therapy is also considered as one of the anti-ulcer drug treatments.
- gastritis and gastric ulcers are caused by a variety of complex causes, and the cause of the disease is still not clearly identified, and thus, there is no absolute method for the treatment.
- Liriodendron tulipifera L. (Yellow-popular) is a deciduous broad-leaved tree belonging to Magnoliaceae, and has been mainly used as a pulp solvent or wood timber. Extracts of wood, bark and leaves of the lily tree contain alkaloids, seskitelpenes and lignan compounds.
- the bark of the yellow-poplar bark has an antimicrobial apolphine alkaloid (Hufford CD and Funderburk MJ, J. Pharm. Sci. 63: 1338-1339,1974; Hufford CD et al., J. Pharm. Sci. 64: 789-792 , 1975).
- Alkaloid-containing lily bark extracts have been used to treat malaria during the American Revolution, and alkaloids, glaucine, have been used as antitussives in the Soviet Union.
- the herbaceous bark is called “American cabbage” and is used for relieving asthma. According to a 1975 study, the alkaloid fraction of the lily tree was antibacterial. Other alkaloids such as N-methyllaurotetanine, lirioferine and liriotulipiferine have antibacterial activity against fungi (Huang Hsu, CY, 1976. MS thesis , North Carlolina State University, Raleigh). In addition, dehydroglaucine and liriodenine, which are known to be cytotoxic, have antimicrobial activity. (Warthen D, Gooden EL and Jacobson M. 1969, J. Pharm. Sci., 58: 637-638, Hufford CD, Funderburk MJ, Morgan J M. et al. 1975, J. Pharm. Sci., 64: 789- 792, Chen CR, Bed JL, Doskotch RW et al., 1974, Lloydia 37: 493-500).
