This invention provides methods of improving cognitive function by administering to a subject a therapeutically effective amount of a fused heterocycle having the formula:
in which R
1
is a member selected from the group consisting of H, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl. R
2
is a member selected from the group consisting of H substituted or unsubstituted alkenyl, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl. R
3
is a member selected from the group consisting of H, C
1
-C
6
substituted or unsubstituted alkyl, substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl. R
4
is a member selected from OH and O
−
X
+
, in which X
+
is positive ion which is a member selected from organic positive ions and inorganic positive ions. Substituted or unsubstituted arylalkyl and substituted or unsubstituted heteroarylalkyl moieties have the formula:
in which Ar is a member selected from the group consisting of substituted or unsubstituted aryl and substituted or unsubstituted heteroaryl. The index n is an integer from 1 to 4.
本发明提供了通过向受试者给予具有以下公式的融合杂环的治疗有效量来提高认知功能的方法:其中R1是从H、取代或未取代的芳基烷基和取代或未取代的杂芳基烷基组成的群体中选择的成员。R2是从H、取代或未取代的
烯基、取代或未取代的芳基烷基和取代或未取代的杂芳基烷基组成的群体中选择的成员。R3是从H、C1-C6取代或未取代的烷基、取代或未取代的芳基烷基和取代或未取代的杂芳基烷基组成的群体中选择的成员。R4是从OH和O-X+中选择的成员,其中X+是有机阳离子和无机阳离子中选择的成员中的正离子。取代或未取代的芳基烷基和取代或未取代的杂芳基烷基基团具有以下公式:其中Ar是从取代或未取代的芳基和取代或未取代的杂芳中选择的成员。指数n是1到4的整数。
