Abstract: Disclosed are compounds of formula (I) wherein A is CH or N, B is CR or N; and D is CR; R represents hydrogen, OH or NH2; R1 and R2, independently of each other, represent hydrogen, N(R3)2, halogen, cyano, nitro, R4-C1-C4alkyl, R4-C1-C4halogenoalkyl, OH, R4-C1-C4alkoxy, R4-C1-C4halogenoalkoxy, SH, R4-C1-C4alkythio, R4-C1-C4halogenoalkylthio; R3 represents, independently at each occurrence, hydrogen, R4-C1-C4alkyl or R4-C1-C4halogenoalkyl; R3a represents, independently at each occurrence, hydrogen or C1-C4 alkyl; R4 represents, independently at each occurrence, hydrogen, halogen, cyano, OH, SH, NH2, NH(CH3) or N(CH3)2; X represents a group of formula -E- or -E-F—, wherein E and F are different from each other and represent a group selected from —C(R3a)2-, —(C?O)—, —NR3a- and —O— and F is linked to Y, with the proviso that if X represents -E-F— one of E or F represents —C(R3a)2— or —(C?O)—; Y represents a group selected from C1-C6alkyl, mono- or bicyclic C3-C11cycloalkyl, which may be partially unsaturated, mon

Abstract: The present invention relates to a compound of formula (I), wherein R1 is hydrogen, lower alkyl, lower alkyl substituted by halogen, halogen, lower alkoxy or lower alkoxy substituted by halogen; R may be the same or different, if n=2 or 3; n is 1, 2 or 3; m is 1, 2 or 3; Ar is a five or six membered heteroaryl group, selected from (II), (III), (IV) or (V) wherein R2 is hydrogen, lower alkyl, lower alkyl substituted by halogen, halogen or lower alkoxy; R3 is hydrogen or halogen; -( ) m - is —(CH2)m— or to pharmaceutically active acid addition salts thereof. The compounds may be used for the treatment of Alzheimer's disease, cerebral amyloid angiopathy, hereditary cerebral hemorrhage with amyloidosis, Dutch-type (HCHWA-D), multi-in-farct dementia, dementia pugilistica or Down syndrome.
