3-Arylcoumarins: Synthesis and potent anti-inflammatory activity
摘要:
Chronic inflammation is the persistent and excessive immune response and can lead to a variety of diseases. Aiming to discover new compounds with anti-inflammatory activity, we report herein the synthesis and biological evaluation of 3-arylcoumarins. Thirty five 3-arylcoumarins were prepared through Perkin condensation and further acid-promoted hydrolysis if necessary. In lipopolysaccharide-activated mouse macrophage RAW264.7 cells, 6,8-dichloro-3-(2-methoxyphenyl) coumarin (16) and 6-bromo-8-methoxy-3-(3-methoxyphenyl) coumarin (25) exhibited nitric oxide production inhibitory activity with the IC50 values of 8.5 mu M and 6.9 mu M, respectively, providing a pharmacological potential as anti-inflammatory agents.

A copper-catalyzed decarboxylative intramolecular CâO coupling reaction was established. Under aerobic conditions in the presence of cupric chloride/1,10-phenathroline, a variety of 2-arylbenzofurans were prepared from 3-arylcoumarins in one-pot with yields from 26% to 84%.
2-phenylbenzo[b]furan glycosides could promote estrogen biosynthesis. To find high active 2-phenylbenzo[b]furans, fifty-four 2-phenylbenzo[b]furans were prepared via four strategies according to corresponding substrate scopes. Biological evaluation in HEK293A cells showed that some compounds exhibited promotive activity on estrogen biosynthesis. 2-(4-Chlorophenyl)-7-methoxybenzo[b]furan possessed the
