Inhibition of the enzymes in the leukotriene and prostaglandin pathways in inflammation by 3-aryl isocoumarins

The biosynthesis of leukotrienes in one of the arachidonic acid pathways and PGE2in the other by 5-LOX and mPGES1 respectively, play pivotal roles in augmenting inflammatory responses. PGE2is known to participate in cancer pathologic

Synthesis of 3-arylisocoumarins by using acyl anion chemistry and synthesis of thunberginol A and cajanolactone A

A new strategy for the synthesis of 3-arylisocoumarins and 8-hydroxy-3-arylisocoumarins was investigated by using acyl anion chemistry for the initial C-C bond formation. The obtained keto esters and keto lactones as intermediates underwent based-promoted intramolecular cyclization to afford 3-arylisocoumarins in good yields. The developed methodology was applied for the synthesis of the important natural products thunberginol A and cajanolactone A.

Development of bioactive functions in Hydrangeae Dulcis Folium. VI. Syntheses of thunberginols A and F and their 3'-deoxy-derivatives using regiospecific lactonization of stilbene carboxylic acid: Structures and inhibitory activity on histamine release of hydramacrophyllols A and B

Lactonization reaction of 2-carboxystilbene mediated by copper(II) chloride proceeded regiospecifically to give the five-membered lactone, while the bromolactonizations using N-bromosuccinimide and anodic oxidation were found to furnish the six-membered lactone. Using these regiospecific lactonization reactions as a key step, antiallergic and antimicrobial isocoumarins and the benzylidenephthalides thunberginols A and F and their 3'-deoxyanalogs were synthesized from phyllodulcin and hydrangenol. Two phthalides called hydramacrophyllols A and B were isolated from Hydrangeae Dulcis Folium and their stereostructures were determined on the basis of physicochemical and chemical evidence, which included the syntheses of hydramacrophyllols A and B from hydrangenol by the application of the lactonization method using copper(II) chloride. In addition, hydramacrophyllols A and B were found to exhibit an inhibitory effect on the histamine release from rat peritoneal exudate cells induced by antigen- antibody reaction.
