The synthesis and biological evaluation of a series of novel norlignans are described. Norlignans were evaluated for their inhibitory activity on the release of β-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 IC(50) values of 18.3 and 17.9 μM, respectively.
