✦ Synopsis

H NMR spectroscopy was used to analyze the interactions between poly(amidoamine) (PAMAM) Starburst dendrimers (SBDs) 1-4 and several biologically important guests (pyridine, quinoline, quinazoline, nicotine and trimethadione). Association constants obtained from changes in the chemical shifts of the amide protons in the host indicate two different interaction sites inside and on the periphery of the dendrimer. Binding at the inner site is inhibited in the ester-terminated dendrimers.
