Study on the cytotoxic activity of drimane sesquiterpenes and nordrimane compounds against cancer cell lines
(MDPI AG, 2014)
Twelve drimanes, including polygodial (1), isopolygodial (2), drimenol (3), confertifolin (4), and isodrimenin (5), were obtained from natural sources. Semi-synthetic derivatives 6-12 were obtained from 1 and 2, and cytotoxic ...
New findings on Simalikalactone D, an antimalarial compound from Quassia amara L. (Simaroubaceae)
(Elsevier, 2012)
Quassia amara L. (Simaroubaceae) is a species widely used as tonic and is claimed to be an efficient antimalarial all over the Northern part of the Amazon basin. Quassinoid compound Simalikalactone D (SkD) has been shown ...
Antileishmanial activity and ultrastructural changes of sesquiterpene lactones isolated from Calea pinnatifida (Asteraceae)
(2019-03-01)
Bioactivity-guided fractionation of antileishmanial active CH 2 Cl 2 phase of MeOH extract from leaves of Calea pinnatifida led to isolation of two sesquiterpene lactones calein C (1) and calealactone C (2), which structures ...
Antibacterial activity of 3,3′-dihydroxycurcumin (DHC) is associated with membrane perturbation
(2019-09-01)
Curcumin is a plant diphenylheptanoid and has been investigated for its antibacterial activity. However, the therapeutic uses of this compound are limited due to its chemical instability. In this work, we evaluated the ...
INFLUENCE OF NONIONIC SURFACTANT COMPOUND ON COUPLED TRANSPORT OF COPPER (II) THROUGH A LIQUID MEMBRANE
(Sociedad Chilena de Química, 2003)
Structural and functional properties of hydration and confined water in membrane interfaces
(Elsevier Science, 2008-12)
The scope of the present review focuses on the interfacial properties of cell membranes that may establish a link between the membrane and the cytosolic components. We present evidences that the current view of the membrane ...
Influence of nonionic surfactant compound on coupled transport of copper (II) through a liquid membrane
(2003)
The influence of a nonionic surfactant compound (sorbitan monooleate) on the coupled transport of Cu(II) ions in a hollow fiber-type solid supported liquid membrane extractor was studied. The acid compound 5-nonylsalicylaldoxime ...
Porosity effects of natural latex (Hevea brasiliensis) on release of compounds for biomedical applications
(2017-12-12)
Natural rubber latex biomedical (NRLb) obtained from the rubber tree Hevea brasiliensis has shown great potential in biomedicine and biomaterial applications. NRLb has been utilized as a physical barrier against infectious ...
