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,OR7and NR8R9; R7, R8and 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 CR11and N; and R11is H or F; for use in treating a disorder associated with protein misfolding stress and in particular associated with accumulation of misfolded proteins. |
