  Pseurotin A and its analogues as inhibitors of immunoglobuline E production

  摘要：

  A natural product, pseurotin A inhibits IgE production in vitro. Wide variety of chemical modi. cation of pseurotin A was performed. Structure-activity relationship studies of pseurotin analogues elucidated that 10-deoxypseurotin A strongly inhibits IgE production with IC(50) of 0.066 mu M. An immunosuppressive activity of another natural product, synerazol was also found. (C) 2009 Elsevier Ltd. All rights reserved.
