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.

据报道,从铜绿微囊藻EAWAG 251中分离并鉴定了三种新的杂环和大环肽,balgacyclamides A–C 。通过2D-NMR方法和质谱法确定组成,并且在使用臭氧后,通过使用Marfey方法的HPLC-MS方法以及使用真实标准品的GC-MS,进行臭氧分解和水解后,确定构型。Balgacyclamides A和B在低微摩尔范围内对恶性疟原虫K1有活性,同时对大鼠成肌细胞毒性低。
