Three new amides from Streptomyces sp. H7372
Three new amides, methyl phenatate A (1), actiphenamide (2) and actiphenol 1-β-D-glucopyranoside (3), along with thirteen known compounds, were isolated from the organic extract of a fermentation culture of Streptomyces sp. H7372. The structures were elucidated by spectroscopic methods including 1D- and 2D-NMR techniques, and MS analyses. Cycloheximide (6) and cyclo(ΔAla-L-Val) (8) gave a clear zone of inhibition of Ras-Raf-1 interaction in the yeast two-hybrid assay which showed high potency with 10 and 25 µm clear ZOIs on SD His- and inactive on SD His+ at 2.5 µg per disk, respectively.
