Synthesis of norlignans and in vitro inhibitory activity of antigen-induced degranulation
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.
Enantioselective total synthesis of the di-O-methyl ethers of (–)-agatharesinol, (+)-hinokiresinol and (–)-sugiresinol, characteristic norlignans of Coniferae
enantioselective syntheses of the di-O-methyl ethers of the norlignans, (–)-agatharesinol (–)-1a, (+)-hinokiresinol (+)-2a and (–)-sugiresinol (–)-3a are described. Grignard addition of vinylmagnesium bromide to an aldimine (–)-13, prepared from the tert-butyl ester 11 and 4-methoxycinnamaldehyde 12, afforded a homochiral vinyl aldehyde, (–)-3-(4-methoxyphenyl)pent-4-enal (–)-14 in >95% ee, which was converted
