The molecule is a carbohydrate-functionalised sequence-defined oligo(amidoamine) in which an Asn-Leu-Phe-Gln-Val-Val-His-Asn-Ser-Tyr-Asn-Arg-Pro-Ala-Tyr-Ser-Pro-Gly amino acid sequence is linked via its terminal glycine residue to the terminal amino group of a (2-{[2-(4-amino-4-oxobutanamido)ethyl]amino}ethyl)amino chain, to the -NH- group proximal to the amino-acid-linked amino group of which is also linked an alpha-L-rhamnosyl-(1->3)-beta-D-glucosyloxy disaccharide unit via a 5-(ethylsulfinyl)pentanoyl chain.
