摘要
Disclosed are compounds of the Formula I chemistry chemdraw filechemistry mol file;wherein: ;R1 is hydrogen, lower alkyl, or cycloalkyl; ;R2 is hydrogen, lower alkyl, lower alkoxy, halogen, hydroxy, aryl, heteroaryl, arylalkyl, heteroarylalkyl, arylalkoxy, heteroarylalkoxy, cyano, carboxy, alkoxycarbonyl, carbamoyl, sulfamoyl, nitro, trifluoromethyl, amino, or mono- or dialkylamino; and ;R3 and R4 independently are hydrogen, lower alkoxy, aryl, heteroaryl, halogen, hydroxy, cyano, carboxy, alkoxycarbonyl, carbamoyl, sulfamoyl, nitro, trifluoromethyl, amino, mono- or dialkylamino, or unsubstituted or substituted lower alkyl or lower alkenyl; or ;R3 and R4 together form an unsubstituted or substituted carbocyclic group. ;Also provided is a method of inhibiting the aggregation of amyloid proteins using a compound of Formula I and a method of imaging amyloid deposits.
