produced by Myrothecium sp. They are novel octapeptides containing alpha-alkyl-alpha-amino acids and a polyamine moiety. The structures were determined by NMR and FAB-MS/MS spectral analyses of the intact peptides. Their absolute configurations were elucidated by GC analysis on a chiral column of the constituent amino acids and by chemical synthesis of the polyamine moieties.
MS-681a,b,c和d是Myrothecium sp。生产的肌球蛋白轻链激酶的新抑制剂。它们是含有α-烷基-α-氨基酸和多胺部分的新型八肽。通过完整肽的NMR和FAB-MS / MS光谱分析确定结构。通过在组成氨基酸的手性柱上进行GC分析以及通过多胺部分的化学合成,阐明了它们的绝对构型。
