A method for labeling &bgr;-amyloid plaques and neurofibrillary tangles in vivo and in vitro, comprises contacting a compound of formula (I):
with mammalian tissue. In formula (I), R1 is selected from the group consisting of —C(O)-alkyl, —C(O)-alkylenyl-R4, —C(O)O-alkyl, —C(O)O-alkylenyl-R4, —C═C(CN)2-alkyl, —C═C(CN)2-alkylenyl-R4 ,
R4 is a radical selected from the group consisting of alkyl, substituted alkyl, aryl and substituted aryl; R5, is a radical selected from the group consisting of —NH2, —OH, —SH, —NH-alkyl, —NHR4, —NH-alkylenyl-R4, —O-alkyl, —O-alkylenyl-R4, —S-alkyl, and —S-alkylenyl-R4; R6 is a radical selected from the group consisting of —CN, —COOH, —C(O)O-alkyl, —C(O)O-alkylenyl-R4, —C(O)-alkyl, —C(O)-alkylenyl-R4, —C(O)-halogen, —C(O)NH , —C(O)NH-alkyl, —C(O)NH-alkylenyl-R4; R7 is a radical selected from the group consisting of O, NH, and S; and R8 is N, O or S. R2 and R3 are each independently selected from the group consisting of alkyl and alkylenyl-R10, wherein R10 is selected from the group consisting of —OH, —OTs, halogen, spiperone, spiperone ketal and spiperone-3-yl. Alternatively, R2 and R3 together form a heterocyclic ring, optionally substituted with at least one radical selected from the group consisting of alkyl, alkoxy, OH, OTs, halogen, alkylenyl-R10, carbonyl, spiperone, spiperone ketal and spiperone-3-yl. In the compounds of formula (I), one or more of the hydrogen, halogen or carbon atoms can, optionally, be replaced with a radiolabel.
