Six new bicyclic peptides, celogentins D -H (1-5) and J ( 6) have been isolated from the seeds of Celosia argentea, and the structures including its absolute stereochemistry were determined by using extensive NMR methods and chemical means. Celogentins E -H (2 -5) and J (6) showed potent inhibition
Seven new cyclic peptides, cyclosquamosins A -G (1 -7), have been isolated from the seeds of Annona squamosa. Their structures and conformation of cyclosquamosin A in solution were elucidated by extensive 2D NMR methods and chemical degradation.
