Abstract [en]

The invention relates to aminotriazole compds. of formula I and pharmaceutically acceptable salts and pharmaceutical compns. thereof, as well as processes for making these compds. for use in the treatment and/or prevention of Aβ-related diseases. I [wherein A is (un)substituted 5- or 6-membered heteroaryl ring comprising at least one N; R1 is H, C1-3-alkyl, cyano, etc.; R2 is (un)substituted C1-6-alkyl, C3-7-cycloalkyl-C1-3-alkyl, heterocyclyl-C1-3-alkyl, etc.; R3 and R4 are each independently selected from H, C1-6-alkyl, (un)substituted C3-7-cycloalkyl, etc.] or pharmaceutically acceptable salts thereof are claimed and exemplified. Example compd. II was prepd. from the reaction of 3-bromo-N-(cyclopropylmethyl)-1-methyl-1H-1,2,4-triazol-5-amine with 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)aniline dihydrochloride under Buchwald-Hartwig conditions in 26% yield. Nine compds. of I were evaluated for inhibition of Aβ formation utilizing electrochemiluminescence anal. and HEK cells expressing amyloid precursor protein (data given). [on SciFinder(R)]
