The isolation and structural characterization of three new heterocyclic and macrocyclic peptides, balgacyclamides A–C, from Microcystis aeruginosa EAWAG 251 are reported. The constitutions were determined by 2D-NMR methods and mass spectrometry, and the configurations were assigned after ozonolysis and hydrolysis by HPLC-MS methods using Marfey’s method as well as GC-MS using authentic standards.

A synthetic pathway for balgacyclamide B was developed in 17-steps and a 2 % overall yield. The synthetic pathway opens a new route towards recently isolated cyanobactin's, especially for the balgacyclamide family and its analogs. Advanced intermediates from the synthetic pathway are being used to explore porin-mediated transportation in gram-negative bacteria.
