Specific noncovalent interactions are commonly used by nature to modulate numerous processes including cell recognition, viral adhesion, and transmembrane communications. Here we report on the design, synthesis, and preliminary characterization of new supramolecular glycodendrimer-based hybrid drugs based on adamantyl-modified glycodendrimers of third, fourth, or fifth generation (mPPI-G3-AdaB, mPPI-G4-AdaB, and mPPI-G5-AdaB) and a new heterobifunctional ligand. This component was tailored to bind through noncovalent interactions both the multimeric natural 5-HT3 receptor (through an optimized arylpiperazine pharmacophore) and the adamantyl groups located on the glycodendrimer surfaces (through a β-cyclodextrin residue) giving rise to biorelevant supramolecular constructs.

UI MeSH Term Description Entries
D008297 Male Males
D011485 Protein Binding The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments. Plasma Protein Binding Capacity,Binding, Protein
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D017208 Rats, Wistar A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain. Wistar Rat,Rat, Wistar,Wistar Rats
D044406 Receptors, Serotonin, 5-HT3 A subclass of serotonin receptors that form cation channels and mediate signal transduction by depolarizing the cell membrane. The cation channels are formed from 5 receptor subunits. When stimulated the receptors allow the selective passage of SODIUM; POTASSIUM; and CALCIUM.

D046911 Macromolecular Substances Compounds and molecular complexes that consist of very large numbers of atoms and are generally over 500 kDa in size. In biological systems macromolecular substances usually can be visualized using ELECTRON MICROSCOPY and are distinguished from ORGANELLES by the lack of a membrane structure.

D047392 beta-Cyclodextrins Cyclic GLUCANS consisting of seven (7) glucopyranose units linked by 1,4-glycosidic bonds. beta Cyclodextrins
D050091 Dendrimers Tree-like, highly branched, polymeric compounds. They grow three-dimensionally by the addition of shells of branched molecules to a central core. The overall globular shape and presence of cavities gives potential as drug carriers and CONTRAST AGENTS.
