摘要:
Disclosed herein are anxiolytic drugs containing as an active ingredient a piperazine derivative represented by the following general formula (I): ##STR1## wherein m represents an integer from 2 to 4,X represents ##STR2## Ar represents a pyridyl group, a pyrimidinyl group, or a phenyl group which may be substituted with halogen atom, trifluoromethyl group, alkoxy group or alkyl group, andR.sub.1, R.sub.2 and R.sub.3 which may be identical or different represent lower alkoxy groups, or R.sub.3 is a hydrogen atom and R.sub.1 when taken together with R.sub.2 forms ##STR3## (n=1, 2 or 3); and its acid addition salt.The anxiolytic drugs disclosed herein have the high binding capacities to 5-HT.sub.1A receptor which is one of the receptors for 5-hydroxytryptamine (5-HT), thereby exerting anxiolytic effects.
摘要:
A medicament for preventive and/or therapeutic treatment of irritable bowel syndrome which comprises as an active ingredient a substance selected from the group consisting of an alkylenedioxybenzene derivative represented by the following general formula (I) and a pharmaceutically acceptable salt thereof, and a hydrate thereof and a solvate thereof: wherein m represents an integer of from 2 to 5, and n represents an integer of from 1 to 3 (e.g., 5-[3-[(2S)-(1,4-benzodioxan-2-ylmethyl)amino]propoxy]-1,3-benzodioxol).
摘要:
An agent comprising a 4-aminoacyltetrahydrofuro�2,3-b!quinoline derivative represented by formula (I): ##STR1## (wherein R.sup.1 represents an alkyl group having 2 to 6 carbon atoms, etc.) or an acid addition salt or a hydrate or a solvent of them as an active ingredient.

摘要:
Sialic acid derivatives represented by the general formula (I): ##STR1## wherein R.sup.1 is a steroidal compound residue; R.sup.2 is H or alkyl; R.sup.3 is alkyl; ##STR2## wherein each of R.sup.6 and R.sup.7 is H, alkyl or the like and I is an integer of 0 to 6; or the like; X is O or S; R.sup.4 is H or acyl; and R.sup.5 is R.sup.14 O-- (R.sup.14 is H or acyl) or R.sup.15 NH--(R.sup.15 is acyl or the like); their salts, hydrates or solvates are provided. Sialic acid derivatives of the present invention are expected to be effective medicines for the prevention and therapy of senile dementia including Alzheimer's disease and the like, because they increase ChAT activity in cholinergic neurons.
摘要:
