Heptavalinamide A, an Extensively N-Methylated Linear Nonapeptide from a Cyanobacterium Symploca sp. and Development of a Highly Sensitive Analysis of N,N-Dimethylvaline by LCMS
2020
An extensively N-methylated linear nonapeptide heptavalinamide A (1) was isolated from the marine cyanobacterium Symploca sp. collected at Kabira Reef of Ishigaki Island, Okinawa. The amino acid sequence of 1 was assigned by interpretation of 2D NMR and MS/MS data. The absolute configurations of the constituent amino acids were determined by the application of Marfey’s method. A method to assign the configuration of N,N-dimethylvaline by LCMS is discussed.
