Talatisamine, a C19-diterpenoid alkaloid from Chinese traditional herbal ‘Chuanwu’
THE TITLE COMPOUND [SYSTEMATIC NAME: (1S,4S,5R,7S,8S,9R,10R,11S,13S,14S,16S,17R)-N-methyl-8,14-dihy-droxy-1,16-tri-meth-oxy-4-(meth-oxy-methyl-ene)aconitane], C(24)H(39)NO(5), was isolated from the roots of Aconitum carmichaelii Debx., which is known as 'Chuanwu' in Chinese traditional herbal medicine. The mol-ecule has an aconitane carbon skeleton with four six-membered rings and two five-memb...
متن کاملDiterpenoid Alkaloids from Delphinium ajacis
Five new diterpenoid alkaloids, ajacisines A–E (1–5), were isolated from Delphinium ajacis, along with seven known alkaloids (6–12). On the basis of their spectral data (IR, UV, HR‐ESI‐MS, 1D and 2D NMR) and chemical properties, the structures of compounds 1–12 were identified. All isolated compounds were evaluated for their in vitro antiviral activities against respiratory syncytial virus, and...

متن کاملNew diterpenoid alkaloids from the roots of Delphinium tiantaishanense.
Four new diterpenoid alkaloids: tiantaishansine (1), tiantaishannine (2), tiantaishanmine (3), and tiantaishandine (4) have been isolated from the roots of Delphinium tiantaishan. Their structures were elucidated by chemical evidence and spectral analyses, including ESI-MS, HR-EI-MS, 1D- and 2D-NMR.
متن کاملThe antitumor effect and mechanism of taipeinine A, a new C19-diterpenoid alkaloid from Aconitum taipeicum, on the HepG2 human hepatocellular carcinoma cell line.
PURPOSE To investigate whether taipeinine A (JNQ2), a C19-diterpenoid alkaloid prepared from the roots of Aconitum taipeicum, has anticancer effects on hepatocellular carcinoma (HCC) and to study its probable anticancer mechanisms. METHODS JNQ2 activities were assessed on human HCC cell line (HepG2) by proliferative assay, cell cycle arrest assay, apoptosis analysis, cell invasion assay and W...
