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.

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
A series of coumarin-resveratrol hybrids, 3-arylcoumarin derivatives 3a-u, were synthesized through the intermolecular condensation reaction of various salicylaldehydes and phenylacetic acids in the presence of 1,4-diazabicyclo[2.2.2]octane under solvent-free conditions. All the synthesized compounds were screened for their inhibitory potency against soybean 15-lipoxygenase. Among them, three compounds (3c, 3j, and 3q) showed good enzyme-inhibitory activities.

The crystal structure determination demonstrates unambiguously that the title compound, 2-[(Z)-3,4-dimethoxyphenylethenyl]-6-methoxypheenyl acetate, C19H20O5, has the Z configuration. The title compound was prepared by decarboxylation of (E)-3-(2-acetoxy-3 -methoxyphenyl)-2-(3,4-dimethoxyphenyl)propenoic acid; this compound was in turn obtained by condensation of 2-acetoxy-3-methoxybenzaldehyde with (3,4-dimethoxyphenyl)acetic acid. H-1 NMR data for the titie compound and the isomeric (E)-2-acetoxy-3,3',4'-trimethoxystilbene are reported.
