[摘要]：The synthesis and biological evaluation of a series of novel norlignans are described. Norlignans were evaluated for their inhibitory activity on the release of beta-hexosaminidase, a marker of degranulation, from RBL-2H3 cells induced by the IgE-antigen complex. The results showed that norlignans 4c and 4e potently inhibited degranulation, with IC50 values of 18.3 and 17.9 mu M, respectively. (C) 2012 Elsevier Ltd. All rights reserved.
