  author={E. Regalado and T. Turk and D. Taşdemir and M. Gorjanc and M. Kaiser and O. Thomas and R. Fernández and P. Amade},
Six new steroidal saponins, pandarosides K-M (1-3) and their methyl esters (4-6), were isolated as minor components, after a careful chemical reinvestigation of the Caribbean sponge Pandaros acanthifolium. Their structures were established on the basis of spectroscopic analyses and comparison with the data obtained from previous metabolites of this family. All new compounds showed moderate to weak activity against four parasitic protozoa. Additionally, these compounds and previously reported… Expand

Correlation among cytotoxicity, hemolytic activity and the composition of steroidal saponins from Paris L.
The cytotoxicity and hemolytic activity of Paris plants collected from twelve places in China provided information about the hemolysis and cytot toxicity of Paris steroidal saponins, which may be useful for their synthesis devoid of Hemolysis toxicity. Expand


Antiprotozoal steroidal saponins from the marine sponge Pandaros acanthifolium.
The chemical composition of the Caribbean sponge Pandaros acanthifolium was reinvestigated and led to the isolation of 12 new steroidal glycosides, namely, pandarosides E-J and their methyl esters (7-12), which showed in vitro activity against three or four parasitic protozoa. Expand
Acanthifoliosides, minor steroidal saponins from the Caribbean sponge Pandaros acanthifolium
Seven novel steroid glycosides, acanthifoliosides A–F (1–6), and the methyl ester of 6 (7), were isolated from the marine sponge Pandaros acanthifolium as minor components. Acanthifoliosides areExpand
Steroidal glycosides from the marine sponge Pandaros acanthifolium
The chemical composition of the Caribbean sponge Pandaros acanthifolium was investigated and led to the isolation of seven new steroidal glycosides, all characterized by a rare 2-hydroxycyclopentenone D-ring with a 14beta configuration. Expand
New unusual pregnane glycosides with antiproliferative activity from Solenostemma argel
Seven new 15-keto pregnane glycosides, namely Stemmosides E--K, were isolated from Solenostemma argel and the effect of these compounds on the VEGF-induced in Kaposi's sarcoma cell proliferation was tested, indicating that all the compounds reduced the cell proliferation in a dose dependent manner.

Haemolytic activity, cytotoxicity and membrane cell permeabilization of semi-synthetic and natural lupane- and oleanane-type saponins.
The results indicate that the cytotoxic lupane-type glycosides 10 and 22 bearing an alpha-l-rhamnopyranose moiety at the C-3 position represent promising antitumour agents for further studies on tumour-bearing mice since they are devoid of toxicity associated with the haemolysis of red blood cells.

Exploration of the correlation between the structure, hemolytic activity, and cytotoxicity of steroid saponins.
The results suggest that steroid saponins execute hemolytic and cytotoxic activity in different mechanisms, and encourage to develop steroid sap onins into potent antitumor agents devoid of the detrimental effect of hemolysis. Expand
Adjuvant and Haemolytic Activities of 47 Saponins Derived from Medicinal and Food Plants
The results suggest that the adjuvant activity of saponins does not relate with haemolytic activity, and it is considered that not only the functional groups themselves, but the overall conformation harmoniously consisting of such functional groups, affects adjUvant activity. Expand
Biological Activities of Aqueous and Organic Extracts from Tropical Marine Sponges
The aqueous extract from Myrmekioderma styx possessed the strongest hemagglutinating activity, whilst AChE inhibiting activity was found only in a few sponges and was generally weak, except in the methanolic extract of T. ophiraphidites. Expand
Hemolytic activities of triterpene glycosides from the holothurian order Dendrochirotida: some trends in the evolution of this group of toxins.
The results correlate with the previously proposed trends in evolution of sea cucumber glycosides from substances having sulfate groups at C-6 of glucose and 3-O-methylglucose units to substances sulfated atC-4 of the first xylose or having no sulfategroups, and from substances with aglycone 16-ketone to substances having no oxygen functions in this position.
