Background: Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities. This study ...

Biflavonoids are dimers of flavonoid moieties linked by a C-C or C-O-C bond. Simple, complex, rearranged, natural and ketalized Diels-Alder adducts, benzofuran derivatives, and spirobiflavonoids are some of the structural ...

Background: Saliva of mosquitoes contains anti-platelet, anti-clotting, vasodilatory, anti-complement and antiinflammatory substances that help the blood feeding process. The salivary polypeptides are at a fast pace ...
