Synthesis of a bifunctional monophosphinic acid DOTA analogue ligand and its lanthanide(iii) complexes. A gadolinium(iii) complex endowed with an optimal water exchange rate for MRI applications
Synthesis of a bifunctional monophosphinic acid DOTA analogue ligand and its lanthanide(iii) complexes. A gadolinium(iii) complex endowed with an optimal water exchange rate for MRI applications
A new facile synthetic strategy was developed to prepare bifunctional monophosphinic acid Ln-DOTA derivatives, Gd-DO2AGAPNBn and Gd- DO2AGAPABn. The relaxivities of the Gd-complexes are enhanced compared to Gd-DOTA. Monophosphinic acid arm of these Gd-complexes affords enhancement of inner sphere water exchange rate due to its steric bulkiness. The different functionalities of DO2AGAPNBn were appended

Catalytic antibodies capable of catalysing activation of a carbamate (-O-CO-NH-) containing prodrug suitable for Antibody Directed Abzyme Prodrug Therapy (ADAPT) by catalysing breakdown of the prodrug at the carbamate position by a non-spontaneous reaction mechanism. The non-spontaneous reaction preferably has a BAc2 mechanism and the prodrug is a preferably a nitrogen mustard aryl carbamate. The invention also includes relevant immunogens, screens for catalytic activity using short transition state analogues and ADAPT systems.

The present invention relates to novel bifunctional chelates that are based on asymmetrical cyclen derivatives. The chelates contain either three acetates and one methylphosphonic arm or three acetates and one methylphosphonic arm enabling to link the chelate through P-alkyl within phosphoric acid derivative or through P—O-alkyl within phosphonic derivative to any organic back-bone suited for targeting. Suitable targeting moieties are monoclonal antibodies, their fragments and recombinant derivatives such as single chain antibodies, diabodies, triabodies, humanized, human or chimeric variants but also peptides, aptamers, spiegelmers, nucleotides, anti sense oligomers and conventional small molecules. These novel bifunctional chelates are suited for the production of kits for the routine labelling of targeting moieties to be used in radiotherapy with radiometals such as Yttrium-90, or for Magnetic Resonance Imagining (MRI) using Gadolinium.
