The present invention relates to a compound of formula (I), or a tautomer and/or a pharmaceutically acceptable salt thereof, wherein: R1 is alkyl, Cl, F or Br; R2 is H or F; R3 is selected from H and alkyl; R4 is selected from H and C(O)R6; R5 is H; or R4 and R5 are linked to form a heterocyclic group which is optionally substituted with one or more R10 groups; R6 is selected from R7, OR7 and NR8R9; R7, R8 and R9 are each independently selected from alkyl, cycloalkyl, aralkyl, cycloalkenyl, heterocyclyl and aryl, each of which is optionally substituted with one or more R10 groups; each R10 is independently selected from halogen, OH, CN, NO2, COO-alkyl, aralkyl, SO2-alkyl, SO2-aryl, COOH, CO-alkyl, CO-aryl, NH2, NH-alkyl, N(alkyl)2, CF3, alkyl and alkoxy; X and Z are each independently CR11, and Y is selected from CR11 and N; and R11 is H or F; for use in treating a disorder associated with protein misfolding stress and in particular associated with accumulation of misfolded proteins.
本发明涉及式(I)化合物或其同系物和/或药学上可接受的盐,其中:R1 是烷基、Cl、F 或 Br;R2 是 H 或 F;R3 选自 H 和烷基;R4 选自 H 和 C(O)R6;R5 是 H;或 R4 和 R5 连接形成杂环基团,该杂环基团任选被一个或多个 R10 基团取代;R6选自R7、OR7和NR8R9;R7、R8和R9各自独立地选自烷基、环烷基、芳基、环烯基、杂环烯基和芳基,其中每个基团都可选择被一个或多个R10基团取代;每个 R10 独立地选自卤素、OH、CN、NO2、COO-烷基、芳基、SO2-烷基、SO2-芳基、COOH、CO-烷基、CO-芳基、NH2、NH-烷基、N(烷基)2、CF3、烷基和烷氧基;X 和 Z 各自独立地为 CR11,Y 选自 CR11 和 N;R11 为 H 或 F;用于治疗与蛋白质错误折叠应激有关的疾病,特别是与错误折叠蛋白质的积累有关的疾病。
