A pterocarpan from Ulex parviflorus
Abstract A new pterocarpan has been isolated from Ulex parviflorus . The structure of this compound, (−)-2,3,4-trimethoxy-8,9-methylenedioxypterocarpan, was established by spectroscopic means. InExpand
Thymus mastichina: Chemical Constituents and their Anti-Cancer Activity
The presence of these constituents identified by colon cancer cytotoxicity-guided activity indicates that extracts of T. mastichna L. may have a protective effect against colon cancers. Expand
Flavonoids from Ulex airensis and Ulex europaeus ssp. europaeus.
From the dichloromethane extract of Ulex airensis three new isoflavonoids, ulexin C (1), ulexin D (2), and 7-O-methylisolupalbigenin (3), were isolated and characterized by spectroscopic methods.Expand
Flavonoids from Ulex Species
The antifungal activity of the isolated compounds was tested by the bioautographic method against Cladosporium cucumerinum and the most active compounds were the pterocarpans, the chalcone and the isoflavones with non-hydroxylated open chain prenyl substituents. Expand
Chemotaxonomy of Portuguese Ulex: quinolizidine alkaloids as taxonomical markers.
Six species of Portuguese Ulex L. in a total of nineteen populations were studied by GC-EIMS as to their content in quinolizidine alkaloids, which allowed the definition of five chemotypes and the recognition of hybrids. Expand
New quinolizidine alkaloids from Ulex jussiaei.
From an acidic extract of Ulex jussiaei four new quinolizidine alkaloids, jussiaeiines A (1), B (2), C (3), and D (4), were isolated and characterized by spectroscopic methods together withExpand
The Role of Spongia sp. in the Discovery of Marine Lead Compounds
The present review covers the literature from 1971 to 2015 and includes studies on the intraspecific diversity of a Mediterranean species, compounds isolated from associated sponge and nudibranch and compounds isolate from S. zimocca and the red seaweed Laurentia microcladia. Expand
Indolizidine and quinolizidine alkaloids structure and bioactivity
Abstract A review of the structural identification and bioactivity of simple indolizidine and quinolizidine alkaloids isolated from amphibians, ants,fungi, plants and marine sources, covering theExpand
Secondary Metabolites and Biological Activity of Invasive Macroalgae of Southern Europe
In this review a brief description of the invasive phenomena associated with algae and its consequences on the ecosystem are presented. Three examples of invasive algae of Southern Europe, belongingExpand
