Abstract: The invention relates to pyrimidines suitable as substrates for O6-alkylguanine-DNA alkyltransferases (AGT) of formula (I) wherein R1 is hydrogen, lower alkyl, halogen, cyano, trifluoromethyl or azido; R2 is a linker; and L is a label or a plurality of same or different labels. The invention further relates to methods of transferring a label from pyrimidines of formula (I) to O6-alkylguanine-DNA alkyltransferases (AGT) and AGT fusion proteins.

Abstract: The invention relates to a precursor for producing sintered metallic components, a method for producing the precursor and the production of the components. The object of the invention is to disclose possibilities of being able to produce sintered metallic components, which render possible an increased physical density and a reduced shrinkage on the fully sintered component. With a precursor according to the invention for the production of sintered metallic components, a coating layer is formed on a core, which is formed from respectively one particle of a first metallic powder. The coating layer is formed with a second powder and a binder. The first powder thereby has a particle size d90 of at least 50 ?m and the second powder has a particle size d90 of less than 25 ?m. The precursor is powdery.

Abstract: The invention relates to compounds comprising a plurality of enzyme substrates suitably linked and further carrying one or more cargo entities. In particular such compounds have the structure (substrate)n-linker-(cargo)m wherein “substrate” is a substrate specific for an enzyme-type protein; n is 2 or more; “linker” is a linking unit consisting of 1 to 300 atoms; “cargo” is a drug, a label detectable by a fluorescence detector, magnetic resonance imaging (MRI), positron emission tomography (PET) or scintigraphy, or a functional group which can be transformed into a drug or a detectable label; and m is 1 or more. The invention further relates to a corresponding molecular shuttles having the structure (fusion protein)n-linker-(cargo)m wherein “fusion protein” is a proteinaceous binding entity fused to an enzyme-type protein for which specific substrates exist. The proteinaceous binding entity is designed to bind to a target structure in vitro or in vivo, for example a cellular receptor.

Abstract: The invention relates to coenzyme A (CoA) type compounds carrying one or more drug entities and optionally a label detectable by a fluorescence detector, magnetic resonance imaging (MRI), positron emission tomography (PET) or scintigraphy, and/or a functional group which can be transformed into a drug or a detectable label. The invention further relates to a molecular shuttle which is a fusion protein comprising a proteinaceous binding entity directed to a target and an acyl carrier protein (ACP) or a fragment thereof, and carrying one or more drug entities. The proteinaceous binding entity is designed to bind to a target structure in vitro or in vivo, for example a cellular receptor.
