Five new pyronane-type monocyclic monoterpenoids, jasminodiol (1), jasminoside H (6), 6'-O-sinapoyljasminoside A (7), 6'-O-sinapoyljasminoside C (8), and jasminoside I (9), together with four known analogues, were isolated from the fruit of Gardenia jasminoides. The structures of the new metabolites were...

The aim of this study was to investigate the effect of 3-(4'-geranyloxy-3'-methoxyphenyl)-2-trans propenoic acid, active principle isolated from Acronychia baueri Schott, and its ester derivatives on biofilm formation by two important oral pathogens, Porphyromonas gingivalis and Streptococcus mutans. The parent...

The 4'-(p-toluenesulfonylamino)-4-hydroxychalcone (TSAHC), which bears inhibitory chemotypes for both alpha-glucosidase and tyrosinase, was evaluated for tyrosinase activity and depigmenting ability relative to compounds designed to only target tyrosianse activity. TSAHC emerged to be a competitive reversible inhibitor of mushroom tyrosinase....
