Anti-angiogenic activity of the flavonoid precursor 4-hydroxychalcone. [PDF]
, 2012 Angiogenesis, the growth of new blood vessels, is necessary for cancerous tumors to keep growing and spreading. Suppression of abnormal angiogenesis may provide therapeutic strategies for the treatment of angiogenesis-dependent disorders.

Does the abiotic environment influence the distribution of flower and fruit colors?
American Journal of Botany, EarlyView.Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Antivascular and antitumor properties of the tubulin-binding chalcone TUB091 [PDF]
, 2016 We investigated the microtubule-destabilizing, vascular-targeting, anti-tumor and anti-metastatic activities of a new series of chalcones, whose prototype compound is (E)-3-(3’’-amino-4’’-methoxyphenyl)-1-(5’-methoxy-3’,4’-methylendioxyphenyl)- 2 ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, EarlyView.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Antiviral effects and mechanism of Qi pi pill against influenza viruses
Animal Models and Experimental Medicine, EarlyView.Qi pi pill presents anti‐influenza effect and inhibits viral replication in vitro by targeting both the viral RNA replication and the release of new viral particles. Furthermore, QPP modulates the production of proinflammatory cytokines induced by influenza infection in host cells.

Synthesis of novel chalcone derivatives by conventional and microwave irradiation methods and their pharmacological activities [PDF]
, 2016 Chalcones are abundant in edible plants and are considered to be the precursors of flavonoids and isoflavonoids. Chalcones belong to an important class of flavonoids, which may be prepared by Claisen–Schmidt condensation.

Angewandte Chemie International Edition, Accepted Article.Catalytic asymmetric 1,3‐dipolar cycloadditions (1,3‐DCA) using iminoesters as ylide precursors offer a powerful approach to accessing stereochemically complex, biologically relevant pyrrolidines. While previous studies have already achieved impressive stereoselectivities, catalytic productivity remains a challenge, with turnover numbers (TON ...
