| abstract |
The present invention is related to a conjugate comprising a structure of general formula (1) [TM1]-[AD1]-[LM]-[AD2]-[TM2] (1), wherein TM1 is a first targeting moiety, wherein the first targeting moiety is capable of binding to a first target, AD1 is a first adapter moiety or is absent, LM is a linker moiety or is absent, AD2 is a second adapter moiety or is absent, and TM2 is a second targeting moiety, wherein the second targeting moiety is capable of binding to a second target; wherein the first targeting moiety and/or the second targeting moiety is a compound of formula (2): wherein R 1 is selected from the group consisting of hydrogen, methyl and cyclopropylmethyl; AA-COOH is an amino acid selected from the group consisting of 2-amino-2 adamantane carboxylic acid, cyclohexylglycine and 9-amino-bicyclo[3.3.1]nonane-9 carboxylic acid; R 2 is selected from the group consisting of (C 1 -C 6 )alkyl, (C 3 -C 8 )cycloalkyl, (C 3 C 8 )cycloalkylmethyl, halogen, nitro and trifluoromethyl; ALK′ is (C 2 -C 5 )alkylidene; R 3 , R 4 and R 5 are each and independently selected from the group consisting of hydrogen and (C 1 -C 4 )alkyl under the proviso that one of R 3 , R 4 and R 5 is of the following formula (3) wherein ALK′ is (C 2 -C 5 )alkylidene; R 6 is selected from the (2) group consisting of hydrogen and (C 1 -C 4 )alkyl; and R 7 is a bond; or a pharmacologically acceptable salt, solvate or hydrate thereof. |
