In the present report, a concise synthesis of viscolin (1) has been achieved. The anti-inflammatory effect of viscolin was investigated in vitro and in vivo. Viscolin blocked the expression of iNOS and COX-2, and it also inhibited the ERK for the activation of NF-κB in LPS-stimulated RAW 264.7 macrophages. Western blotting and immunohistochemical analysis revealed that viscolin decreased Carr-induced iNOS and COX-2 expressions. These results could help to deduce the anti-inflammatory mechanisms.

Little is known about the biosynthesis of yatein, in spite of its importance as a typical heartwood lignan and a key biosynthetic intermediate of the antitumor lignan podophyllotoxin. The present study, based on individual administration of [13C]phenylalanine and deuterium labelled lignans and simultaneous administration of two distinct lignans labelled with deuterium atoms to Anthriscus sylvestris, established the two independent branch pathways from matairesinol, one to afford yatein via thujaplicatin, 5-methylthujaplicatin, and 4,5-dimethylthujaplicatin and the other to bursehernin via pluviatolide. The latter pathway did not lead to yatein, eliminating the presence of a metabolic grid from matairesinol to yatein.

A systematic study of redox couples in fluoro acid medium has been carried out for the oxidative coupling of bisbenzocyclooctadiene lignan precursors.Tl2O3 and Re2O7 were found to be the more efficient reagents with precursors possessing methylenedioxy substituents for the former and only methoxy groups for the latter.Finally, oxidative coupling of a phenolic dibenzylbutane led to a mixture of two BBCOD's, resulting from para and ortho coupling to the phenolic group. - Keywords: Bisbenzocyclooctadienes, Biaryls, Dibenzylbutanolides, Dibenzylbutanes, Phenolic coupling.

Many possible 1-benzyltetrahydroisoquinolines have been examined as possible advanced precursors of the alkaloids hasubanonine (1) and protostephanine (2) in Stephania japonica plants, but none was incorporated significantly.Administration of various precursor molecules having only one aromatic ring, such as tyrosine, has demonstrated that both alkaloids are derived from two different C6-C2 biogenetic units.The subsequent failure of further 1-benzyltetrahydroisoquinolines and bisphenethylamines to be incorporated suggested the intermediacy of either (a) modified 1-benzylisoquinolines or (b) trioxygenated C6-C2 building blocks.Precursors designed to examine the first possibility, such as 1-benzyl-3,4-dihydroisoquinolines or 1-benzyl-1-carboxytetrahydroisoquinolines, were not incorporated into (1) and (2) whereas two 3',4',5'-trioxygenated 2-phenylethylamines were incorporated.These findings allow further delineation of the requirements for later precursors of the alkaloids (1) and (2).
