Aromatic amide compounds of the formula:
wherein R₁, R₂, and R₃ are independently hydrogen, a lower alkyl or lower alkoxy group; Ar is an optionally substituted aromatic group; the group
is C=C or HC-CH; X is hydrogen, CH₂COOH or CH₂CONHAr; and Y is hydrogen or COOH; provided that when X is CH₂COOH or Y is COOH, the COOH may be taken together with the adjacent hydroxy group on the benzene ring to form a lactone ring by dehydration, a quinone form thereof or a pharmaceutically acceptable salt thereof have potent nerve growth factor (NGF) secretion inducing activity, and are thus useful as a drug for the treatment or prophylaxis of degenerative nervous system disorders such as senilic dementis, and Alzheimer's disease.
式中的芳香族酰胺化合物:
其中 R₁、R₂ 和 R₃ 独立地是氢、低级烷基或低级烷氧基;Ar 是任选取代的芳香族基团;基团
是 C=C 或 HC-CH;X 是氢、CH₂COOH 或 CH₂CONHAr;Y 是氢或 COOH;但当 X 为 CH₂COOH 或 Y 为 COOH 时,COOH 可与苯环上相邻的羟基一起脱水形成内酯环,其醌形式或其药学上可接受的盐具有强效的神经生长因子(NGF)分泌诱导活性,因此可用作治疗或预防神经系统退行性疾病(如老年痴呆症和阿尔茨海默病)的药物。
