Popis: | Molecular recognition of biomolecules by synthetic receptors requires modular assembly of various components to complement the molecular characteristics (sizes, topologies, and functional groups) of the substrate. A number of receptors for biorelevant molecules containing oxoanions have been assembled from a bicyclic chiral guanidine subunit. Several receptors accelerate or catalyze reactions proceeding through anionic transition states. Among the structures recently prepared, a receptor incorporating a calix(6)arene subunit has been developed, showing high affhity for phosphocholine derivatives. Chains of tetraguanidinium sulfates form double helices in solution. These substances strongly induce formation of a-helical conformations in Asp rich peptides. |
