We describe here the use of disulfide exchange reactions to generate distinct supramolecular topologies within a dynamic combinatorial library (DCL) derived from tri- and mono-functionalised thiol components in water. This approach allows for the effective expansion of structural diversity within a DCL, and also provides a sensitive probe for weak supramolecular interactions.

The present invention relates to a dynamic chemical network that mimics the transfer of information and ultimately produces a chemical response, for example a readable signal. More specifically, the invention discloses a dynamic system able to selectively sense a biologically-relevant analyte, such as cysteine, in its reduced or its oxidized form (cystine) in aqueous media and in a biofluid (such as urine) for diagnostic application. Due to this property, said dynamic system is useful for the detection of cysteine or its derivatives in biological fluids such as urine.

[structure: see text] Dynamiccombinatoriallibraries (DCLs) containing water-soluble disulfide-linked cages (alongside macrocyclic structures) have been generated and characterized. Unlike most other strategies for generating molecular cages, the structures are held together by covalent bonds, which are formed under thermodynamic control. The diversity of the cages generated opens new possibilities

molecular cages based on disulfide bonds. The use of trifunctional thiols led to a dynamiccombinatorial library (DCL) of readily isolable, multi-component homo and hetero cage-like architectures showing a degree of self-sorting related to the symmetry and size of the trithiol. The work provided detailed kinetic studies and DFT molecular modeling giving original insights into the disulfide cages' properties
