Supramolecular interactions between the host cucurbituril (CB) and amino acids have been widely interrogated, but recognition of specific motifs within a protein domain have never been reported. A phage display approach was herein used to select motifs with the highest binding affinity for the heteroternary complex with methyl viologen and CB… (More)
Pentapeptides containing a Phe residue in the middle of the sequence exhibit ternary complex formation in the presence of cucurbituril, thus opening new perspectives on supramolecular peptide dimerisation studies.
The combination of potent chemical moieties with biologically active proteins is key to some of today's most innovative therapeutic drugs. In order to obviate any chemical modification of the proteins, we present a novel and powerful strategy for the selective conjugation of recombinant protein domains with synthetically derived peptides via a… (More)
Chiral macromolecules have been widely used as synthetic pockets to mimic natural enzymes and promote asymmetric reactions. An achiral host, cucurbituril (CB), was used for an asymmetric Lewis acid catalyzed Diels-Alder reaction. We achieved a remarkable increase in enantioselectivity and a large rate acceleration in the presence of the nanoreactor by… (More)
Peptide aggregation and fibre formation are one of the major underlying causes of several neurodegenerative disorders such as Alzheimer's disease. During the past decades the characterisation of these fibres has been widely studied in an attempt to further understand the nature of the related diseases and in an effort to develop treatments. Transmission… (More)
Amyloid β is one of the peptides involved in the onset of Alzheimer's disease, yet the structure of the toxic species and its underlying mechanism remain elusive on account of the dynamic nature of the Aβ oligomerisation process. While it has been reported that incubation of Amyloid β (1-42) sequences (Aβ42) lead to formation of aggregates that vary in… (More)
All amino acids used, hydroxybenzotriazole (HOBt), dichloromethane (DCM), dimethyl for-mamide (DMF) and 20% piperidine in DMF solution were bought from AGTC Bioproducts and used without further purication. NovaPEG Rink amide LL resin and-aminohexanoic acid (Ahx) were purchased from Merck Novabiochem. Diisopropylcarbodiimide (DIC), diiso-propylethyl-amine… (More)
A supramolecular colorimetric assay utilising the macrocyclic host cucurbituril (CB) with a commercial dye molecule, neutral red (NR), was evaluated as a novel method for drug detection in urine of a model therapeutic peptide drug Octreotide.
