Justicia procumbens is a traditional Taiwanese herbal remedy used to treat fever, pain, and cancer. Justicidin A, isolated from Justicia procumbens, has been reported to suppress in vitro growth of several tumor cell lines as well as hepatoma cells. In this study, justicidin A activated caspase-8 to
Exposure of macrophages to lipopolysaccharide (LPS) induces release of tumor necrosis factor-alpha (TNF-alpha), which is initially synthesized as a 26-kDa pro-TNF-alpha followed by proteolytic processing to a 17-kDa secreted form. In this study, justicidin A, an arylnaphthalide lignan isolated from
A sensitive and accurate LC-ESI-MS/MS method was developed and validated of for the determination of 6'-hydroxy justicidin A (HJA), a potential antitumor active component isolated from Justicia procumbens in rat plasma using a simple liquid-liquid extraction (LLE) method for sample preparation.
Justicidin A (JA) is one of the methanol extracts of Justicia procumbens and was reported to induce apoptosis and inhibit the proliferation of human colon cancer cells. Using bladder cancer as a paradigm, this study was designed to identify the novel molecular basis underlying the antiangiogenic
Our previous reports showed that justicidin A (JA), a novel and pure arylnaphthalide lignan isolated from Justicia procumbens, induces apoptosis of human colorectal cancer cells and hepatocellular carcinoma cells, leading to the suppression of both tumor cell growth in NOD-SCID mice. Here, we reveal
The natural product justicidin A, an arylnaphthalide lignan isolated from Justicia procumbens, significantly inhibited the growth of human colorectal cancer cells HT-29 and HCT 116 at day 6 post-treatment. Further study revealed that justicidin A-treated HT-29 and HCT 116 colorectal cancer cells
Three new arylnaphthalide lignans named 6'-hydroxy justicidin A (1), 6'-hydroxy justicidin B (2) and 6'-hydroxy justicidin C (3) have been isolated from the whole plant of Justicia procumbens, together with four known ones, neojusticin A (4), chinensinaphthol methyl ester (5), isodiphyllin (6) and
A new lignan glycoside, 4-O-alpha-L-arabinopyranosyl-(1' "-->2' ')-beta-D-apiofuranosyldiphyllin (2), named procumbenoside A, and 11 known compounds were isolated from the whole plant of Justicia procumbens. The structure of 2 was established by spectral analysis and chemical methods. The known
HPLC fingerprints were developed for the quality evaluation of Justicia procumbens and its compound preparation, Jian-er syrup, together with the simultaneous quantification of eight arylnaphthalide lignans (6'-hydroxy justicidin B, 6'-hydroxy justicidin A, 6'-hydroxy justicidin C, justicidin B,
Ten compounds, including three lignan glycosides and seven lignans, were purified from Justicia procumbens L. in 8 h using an efficient strategy based on high-speed counter-current chromatography (HSCCC). The two-phase solvent system composed of petroleum-ethyl acetate-methanol-H₂O (1:0.7:1:0.7,
Justicia procumbens is a food and medicine homologous variety, popularly used for making vegetable soups. In this study, a novel mesoporous silica was synthesized and used as the sorbent of solid-phase extraction (SPE) for the purification of lignans from J. procumbens. A laboratory-made SPE
Two new naturally occurring 1-aryl-2,3-naphthalide lignans, cilinaphthalide A (1) and cilinaphthalide B (2), and nine known compounds were isolated from the whole plant of Justicia ciliata. Their structures were established by spectral analysis, and their cytotoxic activity was evaluated against
Five 2,4,6-prenylated phloroglucinols, garcinielliptones HA (1), HB (2), HC (3), HD (4) and HE (5), were isolated from the heartwood of Garcinia subelliptica Merr. Their structures, including relative configurations, were elucidated by means of spectroscopic data analysis. The ability of
Fractionation of the EtOH extract of Justicia procumbens, guided by antiplatelet bioassay, led to the isolation of nine known arylnaphthalide lignans, neojusticin A (1), justicidin B (2), justicidin A (3), taiwanin E methyl ether (4), neojusticin B (5), chinensinaphthol methyl ether (6), taiwanin E
