stereochemistry of melleumin A (1) and B (2), novel peptide compounds isolated from the myxomycete Physarum melleum, was determined by synthesis of their segments and by a modified Mosher's method. Total synthesis of melleuminB (2) was achieved by a stereoselective method, which provided further evidence for all the absolute stereochemistries of melleuminB (2). The Wntsignalinhibitoryactivities of 2 and
