the multivalent ligands is important for successful interaction with multimeric proteins. Polymer-based heterobifunctionalligands that contain pendant groups prearranged into heterodimers can be used to probe the active site and surrounding area of the receptor. Here we describe the synthesis and activities of a series of galactose conjugates on polyacrylamide and dextran. Conjugation of a second fragment

Profile and eliminate! Plasmepsins (PMs), aspartic proteases required for malaria‐parasite growth, are promising antimalarial targets. The in situ screening of PMs with probes formed from β‐hydroxyazides 1 and alkynes with a photo‐cross‐linking unit and a tetraethylrhodamine reporter led to the identification of the small‐molecule inhibitor 2, which inhibits all four food‐vacuole PMs and showed potent
