摘要:
An arylalkanoylamine derivative represented by general formula (I), excellent in a prolyl endopeptidase inhibitory action and resistances to hypoxia and amnesia; and a drug for improving mneme, cerebral circulation and cerebral metabolism, containing the same as the active ingredient, wherein A represents indanyl, indenyl, 1,2,3,4-tetrahydronaphthalenyl or benzofuranyl; m is an integer of 0 to 5; Z represents hydroxymethyl, formyl, nitrile, hydroxyiminomethyl, semicarbazonomethyl or dialkoxymethyl and X and Y may be the same or different from each other and each represents methylene or sulfur, provided that the case where A represents indanyl, indenyl or 1,2,3,4-tetrahydronaphthalenyl, X and Y represent both methylene, and Z represents hydroxymethyl or formyl is excluded.
摘要:
Drugs for improving cerebral circulation, cerebral metabolism and memory containing as the active ingredient a phenylalkanoylamine derivative or its salt represented by general formula (I) (wherein A represents a 1,3-thiazolin-3-yl group, a 1,2,3,6-tetrahydropyridin-1-yl group, a morpholino group, a thiomorpholin-4-yl group or a 3-pyrrolin-1-yl group, R¹ and R² may be the same or different and each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a nitro group, an amino group or (α) (wherein R³ and R⁴ each represents a lower alkyl group or, when taken together, they represent a 5- or 6-membered heterocyclic group together with the nitrogen atom), and n represents an integer of 2 to 6) and novel phenylalkanoylamine derivatives among the compounds represented by (I), and a process for their preparation are disclosed. The above drugs are useful for treating sequelae of cerebral hemorrhage, sequelae of cerebral infarction, arterial aclerosis of brain, sequelae of subarachnoidal hemorrhage, sequelae of head trauma, sequelae of cerebral operation, dementia of cerebral vessel origin, Parkinson's disease, Alzheimer's disease, Pick's disease, sequelae of hypoxia, alcoholic cerebral diseases, etc.
摘要:
A deodorizer comprises a hydrophilic solvent extract of fruit-bodies of champignon mushroom or powder of the extract as an effective component. The extract of champignon mushroom used as an effective component can be prepared by a method which comprises the step of immersing the mushroom in a hydrophilic solvent at a temperature ranging from 60 to 100° C for 15 minutes to 2 hours to perform extraction. The extract can further be treated to obtain the effective components in the form of powder. The extract and the powder thereof can be used as an effective component of a deodorizer capable of oral intake, which serves as a deodorizer for preventing bad smell of environment or an agent for preventing foul breath, which can also be used in foods for eating or drinking to prevent giving out of bad smell emitted from cookings such as those containing garlic and leek as well as cooked fish, which can prevents giving out of bad smell after taking such cookings, and which can be involved in metabolism to thus suppress the giving out of bad smell from urine and feces discharged after eating and drinking such foods.
