In this investigation, new structures based on homoisoflavonoids were designed. Homoisoflavonoids are considered as an important class of flavonoids with various biological properties such as cytotoxicity. A new series of benzylidene-6,7-dihydro-8H-[1,3]dioxolo[4,5-g] chromen-8-one derivatives were developed and their cytotoxic activities evaluated for all compounds on three human breast cancer...

Haematoxylum campechianum is a medicinal plant employed as an astringent to purify the blood and to treat stomach problems such as diarrhea and dysentery. A bio-guided chemical fractionation of the methanolic extract obtained from this plant allowed for the isolation of five compounds: two chalcones known as sappanchalcone (1); 3-deoxysappanchalcone (2); three homoisoflavonoids known as hematox...

A review is presented about the studies that have been carried out on the phenolic composition of the species of the genus Agave in order to show which species of the genus has been analyzed, what is the potential of the species of Agave as source of phenolics with important biological activities, and what is the significance of the phenolic profiles as chemotaxonomic markers in the genus. The ...

The roots of the South American vine Herreria montevidensis Klotzsch ex Griseb. (Herreriaceae) are used in traditional medicine by several Amerindian groups of the Paraguayan Chaco. Little is known on the chemistry of the plant, despite its widespread use across the South American Chaco. From the ethyl acetate/methanol 1:1 extract of the roots, four new and one known homoisoflavanoid, two flava...
