TL;DR: This study investigated the structure/activity relationship of a series of flavonoids on the oxidative burst of human neutrophils in vitro, as a measure of its anti-inflammatory potential, and uncovered new possible strategies for the resolution of inflammatory processes.

TL;DR: The present study points out that the (E)-2-styrylchromones skeleton is an important one which deserves to be developed and further explored as new antiviral drugs against NoV.

TL;DR: In this article, a simple synthesis of new amphiphilic chlorin derivatives from protoporphyrin-IX dimethyl ester is reported based on a straightforward methodology, which involves the Diels-Alder reaction of POR with maleic anhydride followed by addition of nucleophilic species to the initially formed cycloadducts, a transformation which is highly regioselective.

TL;DR: In this paper, the synthesis of two Fesulphos-based chiral ligands and their immobilization on a polystyrene support is described, which act as very efficient catalysts in 1,3-dipolar cycloaddition and allylic substitution reactions providing the products with excellent enantioselectivities.

TL;DR: Nine xanthones, including 3-hydroxy-3-metnylbutyl)-4,8-dihydroxyxanthone, were isolated from the wood of a Thai collection of CALOPHYLLUM TEYSMANNII Miq.
