Abstract:

Oligomeric guanidines can be obtained by polycondensation of guanidine hydrochloride and 1,2-bis(2-aminoethoxy)ethane. A comparative MALDI-TOF mass spectrometry/NMR spectroscopy study with a 13C-labeled sample enabled the unambiguous analysis of a guanidine-based polymer. Among the four major product series unprecedented macrocyclic compounds were detected. The minimum inhibition concentrations for four different microorganisms were determined, showing excellent biocidal activities.
