| titleOfInvention | 2-Aryl-8-oxodihydropurine derivatives as a drug |
| abstract | Medicines for treatment or prevention of dementia comprising 2-aryl-8-oxodihydropurine derivatives of the formula (I): <CHEM> wherein W is H, C1-6 alkyl, halogen, C1-6 alkoxy, or the like; X is H, C1-6 alkyl, a group of the formula (Q):-CH(R<3>)CON(R<1>)(R<2>)(wherein R<1> is a C1-6 alkyl or the like; R<2> is phenyl-substituted C1-4 alkyl or the like; and R<3> is H or the like); Y is H, C1-6 alkyl, a group of the above formula (Q), or the like; and A is substituted phenyl or the like, with the proviso that one of X and Y is a group of the formula (Q) and the other is a group selected from those defined for X or Y except the groups (Q), or pharmaceutically acceptable acid addition salts thereof. The above compounds exhibit an extremely potent ameliorating effect on learning disorder and/or dymnesia and thus are useful in the treatment or prevention of Alzheimer-type dementia, cerebrovascular dementia, senile dementia, etc. |
