Abstract
Three new proline-rich cyclic nonapeptides, cycloleonuripeptides A: cy cle (-Gly-Pro-Pro-Pro-Tyr-Pro-Pro -Met-Ile-), B: cycle (-Gly-Pro-Pro-P ro-Tyr-Pro-Pro-Met(O)-Ile-), and C: cycle (-Gly-Pro-Pro-Pro-Tyr-Pro-Pr o-Met(O)-Ile), have been isolated from the fruits of Leonurus heteroph yllus and their structures were elucidated by extensive 20 NMR methods , chemical degradation and transformation. Cycloleonuripeptides B and C, both of which are epimer, showed cell growth inhibitory activity. C opyright (C) 1996 Elsevier Science Ltd
