Abstract

( E )‐3‐(1 H ‐Pyrrol‐3‐yl)‐2‐propenoic Acid and ( E )‐3‐(1 H ‐Pyrrol‐3‐yl)‐2‐propenamide from Streptomyces parvulus , Strain Tü 2480 The title compounds were isolated from cultures of Streptomyces parvulus . They give a deep blue colour reaction with Ehrlich reagent. Their structures were elucidated by spectroscopy and comparison with synthetic samples. They do not show any antimicrobial activity.
