We report the synthesis of a series of bivalent 1,2,3-triazole linked galactopyranosides as potential inhibitors of cholera toxin (CT). The inhibitory activity of the bivalent series was examined (ELISA) and the series showed low inhibitory activity (millimolar IC50s). Conversely, the monomeric galactotriazole analogues were strong inhibitors of cholera toxin (IC50 = 71–75 μM).

most efficient AAP shows binding affinities comparable to azobenzenes, but more effective switching and higher thermal stability of the Z-isomer. As a proof-of-principle, we investigated two CD-based supramolecular systems, containing either cyclodextrin vesicles (CDVs) or cyclodextrin-functionalized goldnanoparticles (CDAuNPs), which revealed excellent reversible, light-responsive aggregation and
