  Synthesis and structure of diastereomers of pentenocin B produced by Trichoderma hamatum FO-6903

  摘要：

  All diastereomers of pentenocin B, an inhibitor of interleukin-1beta converting enzyme produced by Trichoderma hamatum FO-6903, were synthesized in chiral forms starting from L-threonine. Absolute configurations of natural pentenocin B were clarified to be 4S, 5R, and 6R. (C) 2004 Elsevier Ltd. All rights reserved.
