A family of six novel p-hydroxyacetophenone amides, 1-6, was isolated from Cystobacter ferrugineus, strain Cb G35. Their structures were elucidated by ESI-TOF mass spectrometry and NMR spectroscopy. Feeding experiments with labeled [¹³C₉,¹⁵N]-tyrosine and [d₁₀]-leucine identified the biosynthetic precursors of 1.
