  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

  雌激素的生物合成对人类的许多生理过程至关重要。雌激素水平异常与多种疾病密切相关，包括乳腺癌和骨质疏松症。以前我们发现2-苯基苯并[b]呋喃糖苷可以促进雌激素的生物合成。为了找到高活性的2-苯基苯并[b]呋喃，根据相应的底物范围，通过四种策略制备了五十四种2-苯基苯并[b]呋喃。HEK293A细胞的生物学评估表明，某些化合物对雌激素的生物合成具有促进作用。2-（4-氯苯基）-7-甲氧基苯并[b]呋喃具有最高的活性，EC50值为14.68μM。此外，这些化合物不会影响HEK292A细胞中的芳香化酶表达，
