    Abstract The tropical plant Annona muricata has been widely used for traditional ethnobotanic and pharmacologic applications. Extracts from different parts of this plant have been shown to have a wide range of biological activities. In the present study, we carry out a metabolomic study of both aqueous and DMSO extracts from Annona muricata leaves that has allowed us to identify 33 bioactive compounds. Furthermore, we have shown that aqueous extracts are able to inhibit endothelial cell migration and both aqueous and DMSO extracts inhibit the formation of tubule-like structures by endothelial cells cultured on Matrigel. We conclude that extracts of Annona muricata leaves have great potential as anti-angiogenic natural combinations of bioactive compounds.

    Abstract Inclusion of quinoidal cores in conjugated hydrocarbons is a common strategy to modulate the properties of diradicaloids formed by aromaticity recovery within the quinoidal unit. Here we describe an alternative approach of tuning of diradical properties in indenoindenodibenzothiophenes upon anti → syn isomerism of the benzothiophene motif. This alters the relationship of the S atom with the radical center from linear to cross conjugation yet retains the same 2,6-naphtho conjugation pattern of the rearomatized core. We conduct a full comparison between the anti and syn derivatives based on structural, spectroscopic, theoretical, and magnetic measurements, showing that these systems are stable open-shell singlet diradicaloids that only access their triplet state at elevated temperatures.
