A compound of the formula:
wherein Ar is an aromatic group; X and Y are a bivalent group selected from -O-, -S-, -CO-, -SO-, -SO2-, -NR8-,-CONR8-, SO2NR8 and -COO- (wherein R8 is H, a hydrocarbon group or acyl), or a bivalent C1-6 aliphatic hydrocarbon group which may contain one or two above bivalent groups; R1 and R2 are H or C1-6 alkyl, or R1 and R2 may form, together with the adjacent nitrogen atom, a nitrogen-containing heterocyclic ring; and ring A is a monocyclic aromatic ring, or a salt thereof or a prodrug thereof exhibits an excellent inhibitory activity of the production and/or the secretion of amyloid-β protein.
式中的化合物: 其中 Ar 是芳香基;X 和 Y 是选自-O-、-S-、-CO-、-SO-、-SO2-、-NR8-、-CONR8-、SO2NR8 和-COO-(其中 R8 是 H、烃基或酰基)的二价基团,或可包含一个或两个上述二价基团的二价 C1-6 脂肪族烃基; R1和R2为H或C1-6烷基,或R1和R2可与相邻的氮原子一起形成含氮杂环;以及环A为单环芳香环,或其盐或其原药对淀粉样β蛋白的产生和/或分泌具有极佳的抑制活性。
