Compounds, compositions, and methods comprising a polyamine compound are described, which may be used to kill, disperse, treat, or reduce biofilms, or to inhibit or substantially prevent biofilm formation. In certain aspects, the present invention relates to compounds, compositions, and methods comprising polyamine compounds that have antimicrobial or dispersing activity against a variety of bacterial strains capable of forming biofilms.
Dimeric, trimeric, and tetrameric cyclic [2]catenanes have been prepared directly through one‐pot sodium‐ion‐templated dynamic imine formation from a diamine and a tetraaldehyde. NaBH4 mediated reduction of the labile imino bonds of these cyclic [2]catenane oligomers, followed by methylation of the resulting secondary amino groups enabled the isolation and characterization of oligomeric cyclic [2]catenanes

condensation and alkynemetathesis. Catalyst VI is demonstrated to successfully engender the metathesis of imine-bearing substrate 7, while catalyst III does not. The susceptibility of catalyst VI to deactivation by hydrolysis and ligand exchange is demonstrated. Assembly and disassembly of ladder 8 in one pot were demonstrated in the presence and absence of a Lewis acid catalyst.
