WA8242A1, A2 and B, Novel Secretary Phospholipase A2 Inhibitors Produced by Streptomyces violaeeusniger. III. Structure Elucidation and Total Synthesis of WA8242B.
The structure of WA8242B, a potent novelinhibitor against phospholipaseA2, was fully characterized by spectroscopic methods and chemical degradation. The success of totalsynthesis of WA8242B confirmed the structure and allowed the pharmacological study of WA8242B. The structures of WA8242A1 and A2 were also described.
