Non-small cell lung cancer is the most common type of lung cancer and the most common cause of cancer-related death in humans. TXA9, which is a natural product separated from an anti-tumor-active fraction of the roots of Streptocaulon juventas, may possess potent anti-proliferative activity
To study the anticancer activity of griffithin from Streptocaulon griffithii Hook. f. and its effect on apoptosis of cancer cells in vitro, the inhibitory effect of griffithin on cell proliferation was studied by MTT assay, the cell apoptosis was observed by AO/EB double decoration assay and flow
In the present study, a 75% ethanol extract of Streptocaulon juventas (SJ), which had a strong inhibitory effect on the proliferation of human lung A549 adenocarcinoma cells, was subjected to bioassay-guided fractionation. The most active fraction (SJF) was obtained using a macroreticular resin
Corchorusoside C (1), isolated from Streptocaulon juventas collected in Vietnam, was found to be nontoxic in a zebrafish ( Danio rerio) model and to induce cytotoxicity in several cancer cell lines with notable selective activity against prostate DU-145 cancer cells (IC50 0.08 μM).
Three new C21 steroids, i.e., (3β,17α,20S)-pregn-5(6)-ene-3, 17, 20-triol-3-O-β-d-digitalopyranosyl-(1 → 4)-β-d-digitalopyranoside (4), (3β,17α,20S)-pregn-5(6)-ene-3, 17, 20-triol-20-O-β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranosyl-(1 → 2)-β-d-digital-opyranoside (8), (3β, 20R)-pregn-14(15)-ene-3,
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
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
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),
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
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.
OBJECTIVE
For identification of the active constituents we investigated the anticancer activity of cardenolides from Streptocaulon tomentosum Wight & Arn. (Asclepiadaceae) and from Nerium oleander L. (Apocynaceae) which are both used against cancer in the traditional medicine in their region of
Methanol, methanol-water (1:1) and water extracts were prepared from seventy-seven Vietnamese medicinal plants and tested for their antiproliferative activities against human HT-1080 fibrosarcoma cells. Among them, fifteen extracts including seven methanol extracts of Caesalpinia sappan,
