Abstract

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