The 2Z-isomer of malyngamide K has been isolated along with the known compounds malyngamideC, deoxy-C and K, and characterized from a Papua New Guinea field collection of the cyanobacterium Lyngbya majuscula. The planar structure was deduced by 1D and 2D NMR spectroscopic and mass spectral data interpretation. The absolute configurations were determined on the basis of spectroscopic techniques, chemical
马林酰胺 K 的 2Z-异构体已与已知化合物马林酰胺 C、脱氧-C 和 K 一起分离出来,并从巴布亚新几内亚现场收集的蓝藻 Lyngbya majuscula 中进行了表征。通过一维和二维核磁共振波谱和质谱数据解释推导出平面结构。绝对构型是根据光谱技术、化学降解和DFT理论计算确定的。
