A series of inhibitors targeting human cathepsins have been designed and synthesized following a combinatorial approach. The compounds bear an α,β-unsaturated phenyl vinylsulfone or ethyl acrylate warhead and a peptidomimetic portion aligned to the non-primed binding region. Biochemical evaluation toward four human cathepsins was carried out and the kinetic characterization confirmed an irreversible
Cell-Surface Receptor–Ligand Interaction Analysis with Homogeneous Time-Resolved FRET and Metabolic Glycan Engineering: Application to Transmembrane and GPI-Anchored Receptors
transfer between receptorglycans and fluorescently labeled ligands. We describe GlycoFRET for a GPI-anchored receptor, a G-protein-coupled receptor, and a heterodimeric cytokine receptor in livingcells with excellent sensitivity and high signal-to-background ratios. In contrast to previously described methods, GlycoFRET does not require genetic engineering or antibodies to labelreceptors. Given that
Fluorescently labelled NPY Y1 receptor (Y1R) ligands were synthesized by connecting pyrylium and cyanine dyes with the argininamide-type Y1R antagonist core structure by linkers, covering a wide variety in length and chemical nature, attached to the guanidine group. The most promising fluorescentprobes had Y1R affinities (radioligand binding) and antagonistic activities (calcium assay) in the one-

from extracellular release of drug in undesired tissues or direct activity in bystander cells. By incorporating highly polar, anionic moieties via short polyethylene glycol linkers into compounds with known intracellular, and cell-surface targets, we have been able to correlate the cellular activity of compounds with their subcellular site of action. For compounds with nuclear (Brd, PARP) or cytosolic
