Abstract: The invention relates to novel small molecule compounds having a basic structure as depicted by formula (A), where in particular exemplary embodiments R1 is —OH, R2 is —NO2 and R3 is H, R4 and R5 are H, one of R6 and R7 is selected from H, —CONH2, and —CONR92, and the other one is selected from —CONR92 and —CONR11R9, wherein R9 and R11 are (possibly multiply) substituted alkyl and H or alkyl, respectively. The compounds of the invention inhibit the enzyme Catechol-O-methyltransferase (COMT) and exhibit a low off-target profile. The compounds are provided for use as a medicament, in particular for use in prevention or treatment of Parkinson's disease.

Abstract: The invention relates to a method for tagging, identifying and isolating a target cell, wherein the cell is contacted with a capture compound comprising a small molecule moiety, for example a pharmaceutical drug molecule, capable of selectively binding with the cell surface of the target cell, and a function that is capable to covalently or quasi-covalently bind to a surface as a marker or tagging function. In some embodiments the capture compound also includes a photoactivatable reactivity function. The capture compound attaches to a particle that mediates identification or isolation of the tagged cell.

Abstract: The invention relates to a process for isolating and/or characterising biomolecules and/or biomolecule fragments, in particular proteins and/or protein fragments, comprising the steps: provision of an immobilized compound IC through the interaction of a capture compound CC and the target compound T and a carrier compound CCB, carrying out a division step, in which a cleavable function F is cleaved, and a division compound DC is produced, and isolation and/or characterisation of said division compound DC. The invention relates further to a carrier compound CCB, a capture compound CC, a precursor compound PC and a division compound DC.
