摘要

Use of a non-peptide bradykinin antagonist (A) or its salts is claimed for treatment and prevention of Alzheimer's disease. Preferably (A) have the formula (I). R'+R" = N=X1-X2=X3, N=C(R3)-X4, X4-C(R3)=N, X4-CO-X4 or O-C(R3)=C(R3); E = H, halo, alkyl, alkylthio, alkoxy or Q-A-Ar; Ar = phenyl substituted by N(R14)(A')C(W)YR15 etc.; X1 = N or CR4; X2 = N or CR5; X3 = N or CR6; X4 = O, S, N or NR7; R1, R2 = H, halo, alkyl or alkoxy; R3 = H, halo, 1-6C alkyl, aryl, 1-3C-alkyl-aryl, 3-5C alkenyl, alkoxy or CO2R11; R4 = H, halo, OH, alkyl, alkylthio, NH2, mono- or di-alkylamino, alkoxy, or aryl (optionally substituted); R5 = H, alkyl or COZ; R6 = as for R4 etc.; R7 = alkyl, aryl or 1-3C alkyl-aryl; A = 1-3C alkandiyl; Q = O or NR11; R11, R14 = H or alkyl; Z = NR14R22; R22 = (CH2)nN(R14)2 or 1-substituted piperidin-4-yl; alkyl, alkoxy have 1-4C, and aryl has 6-12C, unless specified otherwise.
