摘要 | A cyclic hexapeptide, annomuricatin A (the molecular formula: C27H38N6O7), was isolated from the seeds of Annona muricata. The types and sequence of the amino acids were confirmed by X-ray diffraction analysis. The stereochernistry of the title cyclopeptide was clarified by X-ray crystallographic study. The backbone contains two beta-turns, one is type I beta-turn and the other is type II, which are stabilized by two transarmular 4 -> 1 backbone hydrogen bonds between Ala and Phe. There are intermolecular hydrogen bonds between the cyclopeptide and the solvent molecules which maintained the steady spatial arrangement in crystal. (c) 2006 Elsevier B.V. All rights reserved. |
