Identification of Congocidine (1), Distamycin (2), and a novel pyrrolamide compound (3) in <i>S. netropsis</i>.

Abstract

<p>(A) High resolution mass spectrum of Congocidine and Distamycin. (B) Precursor ion scan-directed mass spectrum to identify compound <b>3</b>. Base peak chromatograms of precursor ion scan are shown. Ions of <i>m</i>/<i>z</i> 273 and 247 are daughter ions of compound <b>3</b>, and were used as the queries.</p
