Two new sulfur-containing amides, entadamide A (1) and entadamide B (2), isolated from the seeds of Entadaphaseoloides, were synthesized by the addition reaction of methanethiol to propiolic acid (5) followed by condensation with ethanolamine by the use of dicyclohexylcarbadiimide. These compounds inhibited the 5-lipoxygenase activity of RBL-1 cells at 10(-4) g/ml. This finding suggests that entadamides
