A new cardenolide, 3-O-(beta-glucopyranosyl)acovenosigenin A (1), was isolated from the roots of Streptocaulon griffithii, together with eight known cardenolides, compounds 2-9. All compounds showed significant in vitro inhibition of the proliferation of the human gastrointestinal cancer cell line

A new cardenolide glycoside from the roots of Streptocaulon juventas (lour.) merr. (Asclepiadaceae).

Numai utilizatorii înregistrați pot traduce articole

From remaining aqueous fraction of the roots of Streptocaulon juventas, one new cardiac glycoside named periplogenin 3-O-β-gentiobioside (1) together with six known ones (2-7) were isolated. Their relative structures were elucidated based on NMR spectroscopic

Cardenolide glycosides from root of Streptocaulon juventas.

Numai utilizatorii înregistrați pot traduce articole

Six cardenolides were isolated from the anti-tumor active fraction of the 75% ethanol extract of Streptocaulon juventas (Asclepiadaceae), mainly found in southwest of China. These were named 1α, 14β-dihydroxy-5β-card-20 (22)-enolide 3-O-[O-β-D-glucopyranosyl-(1→2)-β-D-digitalopyranoside] (1),

The cytotoxic activities of cardiac glycosides from Streptocaulon juventas and the structure-activity relationships.

Numai utilizatorii înregistrați pot traduce articole

A series of cardiac glycosides were isolated and identified from the anti-tumor fraction of the root of Streptocaulon juventas in previous studies. In the present research, the cytotoxic activities of the 43 cardiac glycosides on three cell lines, human lung A549 adenocarcinoma cell, large cell lung

Identification and screening of cardiac glycosides in Streptocaulon griffithii using an integrated data mining strategy based on high resolution mass spectrometry.

Numai utilizatorii înregistrați pot traduce articole

The present study was designed to develop a practical strategy to tackle the problem of lacking standard compounds and limited references for identifying structure-related compounds in Streptocaulon griffithii Hook. f., especially those in trace concentrations, with a focus on antitumor activity.
