Abstract
The present invention relates to cryptate compounds useful as chelating agents. In particular, the present invention relates to functionalized derivatives of certain cryptate compounds. These functionalized derivatives are suitable for use in radiolabelling and similar applications. The present invention also relates to a method for diagnosis or therapy of a disease utilizing functionalized derivatives of cryptase compounds. In one embodiment, the present invention relates to a compound which is capable of being radiolabelled of general formula (I) in which n represents an integer from 2 to 4, where each Rand Ris independently selected from —H, CH, COOH, NO, CHOH, HPO, HSO, CN, C═ONHand CHO; X and Y are the same or different and are selected from the group of C—R, N, P and C—Z in which R represents a hydrogen or halogen atom or a hydroxyl, nitro, nitroso, amino, optionally substituted alkyl, optionally substituted aryl, optionally substituted aralkyl or cyano group, or a group of the formula —COOR', COCOOR′, NH—COCHBr, —NH—CO—CH═CH—COOR′ in which R′ is a hydrogen atom or alkyl group; or, W is selected from the group of NH, S and O; and Z is a functionalized linkage group which is capable of binding said compound of formula (I) to a molecular recognition unit and wherein at least one of X and Y is C—Z; or a pharmaceutically acceptable salt thereof
