Inhibition of the symbiotic fungus of leaf-cutting ants by coumarins
(2005-05-01)
Leaf-cutting ants are known to be a serious pest for agriculture due to the high amounts of vegetal matter from crops used by them in order to cultivate a symbiotic fungus on which they rely for food and enzymes. The ...
Two new O-geranyl coumarins from the resinous exudate of Haplopappus multifolius
(Elsevier, 2004)
From the resinous exudate of leaves of Haplopappus multifolius two new coumarins were isolated and assigned the structures 6-hydroxy-7-(5′- hydroxy-3′,7′-dimethylocta-2′,6′-dien)-oxycoumarin (1) and 6-hydroxy-7-(7′-hydro ...

Phytochemical investigation of rhizomes and leaves of Dorstenia asaroides Gardn. in Hook. (Moraceae) afforded the furocoumarins psoralen and bergapten, the triterpenes α-amyrin, α-amyrin acetate, β-amyrin acetate, lupeyl ...
Gastroprotective activity of synthetic coumarins: Role of endogenous prostaglandins, nitric oxide, non-protein sulfhydryls and vanilloid receptors
(Elsevier, 2016)
Natural or synthetic coumarins showed gastroprotective and antiulcer activity in animal models. In this study, we have synthetized twenty coumarins using classic methods to evaluate their gastroprotective effects on the ...
