The first example of a folateâcalix[4]arene conjugate was designed and synthesized via microwave-assisted click chemistry. In PBS medium at physiological pH, the conjugate formed soluble aggregates and showed the capability to improve the water-solubility of a hydrophobic drug model, such as indomethacin.

A new series of water-soluble tetravalent glycoclusters incorporating beta-lactosyl residues attached to a central calix[4]arene core was synthesised using azide-alkyne Cu(I)-catalysed cycloaddition ('click chemistry'). Carbohydrate moieties were attached either to the upper or lower rim of rigid cone-shaped or partial cone macrocycles via 14-21 atom spacer arms. The glycoclusters with a C(4)-symmetrical arrangement of beta-lactosyl residues showed trypanocidal activity, with one of them showing comparable activity to established anti-trypanosomal drug benznidazole in in vitro anti-parasite assays.
