摘要:
The present invention discloses a method for modifying the pharmacokinetics of a hapten which is useful as an in vivo radioimaging or radiotherapeutic agent. Compositions comprising a derivatized hapten of the invention are provided for in vivo imaging and therapy. A compound of Formula (I): p-R 1 -C 6 H 4 -CH 2 -EDTA-M (I) wherein R 1 is R 2 is hydrogen, an amino group, -OC(̵Y), -p-phenyl-CH 2 -Y, an unsubstituted C 1 to C 30 branched or straight chain alkyl group; a substituted C 1 to C 30 branched or straight chain alkyl, cycloalkyl, aryl or arylalkyl group, in which the substituents are one or more of any of: hydroxy, carboxy, =O, =S, -S-, -SR 4 , fluoro, chloro, bromo, iodo, amino, nitro, -S0 3 H, -NHR 3 , -NHR 4 , -N(R 3 ) 2 , -CONHR 3 , -COOR 3 , -SO 4 , -PO 4 , phenyl, benzyl, imidazolo, or a group of the formulae: wherein R 3 is hydrogen, a C 1 to C 30 straight or branched chain alkyl group, -p-phenyl-CH 2 -Y, or a non-reactive functional group; Y is EDTA, DTPA, DOTA, HETA, TRITA or TETA; R 4 is H or and, M is a metal ion, or a pharmaceutically-acceptable salt thereof.
