or a pharmaceutically acceptable salt thereof.

A compound comprising a prostate specific membrane antigen (PSMA)-targeting moiety of the following formula or of a salt or a solvate thereof. R.sup.0 is O or S. Each of R.sup.1a, R.sup.1b and R.sup.1c may be —CO.sub.2H, —SO.sub.2H, —SO.sub.3H, —PO.sub.2H, or —PO.sub.3H.sub.2, for example. R.sup.2 may be methylene or a derivative thereof, propylene or a derivative thereof, or a derivative of ethylene, optionally substituted. R.sup.3 is a linker. When the PSMA-targeting moiety is linked to a radiolabeling group, the compound may be used as an imaging agent or therapeutic agent for PSMA-expressing diseases/conditions.

The invention generally relates to a smart drug delivery system for dual nuclear medical cytotoxic theranostics incorporating either (i) a first compound with the structure CT-L1-Chel-S1-TV or

##STR00001##

or (ii) a second compound with the structure Chel-S-TV and a third compound with the structure CT-L-TV. In the first, second and third compounds Chel is a radical of a chelating agent for complexing a radioisotope; CT is a radical of a cytotoxic compound; TV is a biological targeting vector; L1 and L are each linkers; S1, S2 and S are each spacers.

In a compound of the present invention, in a macroscopic view of a chemical structure thereof, a chelating moiety is located at the center of the structure, an atomic group containing an albumin binding moiety binds to one side of the chelating moiety, and an atomic group containing a target molecule binding moiety binds to the other side of the chelating moiety. The chelating moiety is also preferably DOTA or a derivative thereof. The target molecule binding moiety preferably has a structure to bind to a target molecule expressed in a cancer tissue. The present invention also provides a radioactive labeled compound in which the compound is coordinated to a radioactive metal ion.

A compound of general formula (I): wherein: n is 1, 2 or 3; R1, R2, R3 and R4, independently represent OH or Q; and 20 Q represents a tissue-targeting moeity selected from the group consisting of or a stereoisomer, a hydrate, a solvate, or a salt thereof, or a mixture of same, methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds and the use of said 25 compounds for manufacturing pharmaceutical compositions for the treatment or prophylaxis of diseases, in particular of soft tissue diseases, as a sole agent or in combination with other active ingredients.
