Substituted polycarboxylic ligand molecules and corresponding metal complexes of said ligands, preferably paramagnetic metals complexes for generating responses in the field of magnetic resonance imaging (MRI). The paramagnetic complexes of the polycarboxylic ligands possess advantageous tensioactive properties and are useful as MRI contrast media in formulations for investigating the blood pool.

ImmH (1) and DADMe-ImmH (2) are potent inhibitors of human purinenucleoside phoshorylase (PNP), developed by us and currently in clinical trials for the treatment of a variety of T-cell related diseases. Compounds1 and 2 were used as templates for the design and synthesis of a series of acyclic immucillin analogues (8−38) in order to identify simplified alternatives to 1 and 2. SerMe-ImmG (8) and

The present invention relates to a compound comprising an alpha-end and an omega-end, the compound comprising on the alpha-end a reactive group Qlcapable of reacting with a functional group F1present on a biomolecule and on the omega-end a target molecule, the compound further comprising a group according to formula (1) or a salt thereof: Said compound may also be referred to as a linker-conjugate. The invention also relates to a process for the preparation of a bioconjugate, the process comprising the step of reacting a reactive group Q1of a linker-conjugate according to the invention with a functional group F1of a biomolecule. The invention further relates to a bioconjugate obtainable by the process according to the invention. In a preferred embodiment, the invention concerns a process for the preparation of a bioconjugate via a cycloaddition, such as a (4+2)-cycloaddition (e.g. a Diels-Alder reaction) or a (3+2)-cycloaddition (e.g. a 1,3-dipolar cycloaddition).

bilayer vesicles formed from these surfactants could be polymerized either by exposure to ultraviolet irradiation or by the use of azoisobutyronitrile as an initiator. The presence of vesicles (unpolymerized and polymeric) has been demonstrated by electron micrography, H/sup 1/ NMR, gel filtration, phase transition, turbidity changes, substrate entrapment, and permeability. Polymerizedvesicles are considerably
