Steroidal alkaloids from Veratrum taliense
نویسندگان
چکیده
Phytochemical reinvestigation of the roots and rhizomes of Veratrum taliense yield three known (solanidine, veramiline-3-0-~D-glucopyranoside and stenophylline B-3-0-~D-glucopyranoside) and two novel steroidal alkaloids. The structures of the new compounds have been established by a combination of spectroscopic methods as 3angeloylzygadenine-I3-N-oxide and (20S,25S)-22,26-epiminocholesta-5,22-diene-3I3,12a.-diol (named veramitaline). The chemotaxonomic significance of the isolates are discussed briefly. .

Alkaloids from Veratrum taliense Exert Cardiovascular Toxic Effects via Cardiac Sodium Channel Subtype 1.5.
Several species of the genus Veratrum that produce steroid alkaloids are commonly used to treat pain and hypertension in China and Europe. However, Veratrum alkaloids (VAs) induce serious cardiovascular toxicity. In China, Veratrum treatment often leads to many side effects and even causes the death of patients, but the pathophysiological mechanisms under these adverse effects are not clear. He...
متن کاملSteroidal alkaloids of Veratrum lobelianum Bernh. and Veratrum nigrum L.
Twelve steroidal alkaloids were isolated from four populations of Veratrum lobelianum Bernh. and Veratrum nigrum L. Full NMR data for veralosinine (1), and extensive 1H NMR data for veralosine (3) and teinemine (5) are presented here for the first time. (+/-)-15-O-(2-Methylbutyroyl)germine (10) is undescribed up to now. The antiproliferative activities of veranigrine, veralosinine, and neogermi...
متن کاملFrom teratogens to potential therapeutics: natural inhibitors of the Hedgehog signaling network come of age.
Steroidal alkaloids from Veratrum californicum (Durand) are known to exert teratogenic effects (e.g., cyclopia, holoprosencephaly) by blocking the Hedgehog (Hh) signaling pathway, which plays a considerable role in embryonic development and organogenesis. Most surprisingly, recent studies demonstrate that this complex signaling network is active even in the healthy adult organism, where it seem...

Germidine is one of ester type steroidal alkaloids extracted from Veratrum Nigrum L. var. ussuriense Nakai (“Wusuli Lilu” in Chinese), a herbal medicine that has long been used as an anti-hypertensive remedy in Chinese traditional medicine. Although the antithrombotic effects of the Veratrum nigrum alkaloids (VnA) have been reported , the effective chemical constituent of VnA is still unclear. ...

Alkaloids constitute the largest class of plant secondary compounds, occurring in 20 to 30% of perennial herbaceous species in North America. Alkaloid-containing plants are of interest, first because alkaloids often have pronounced physiological reactions when ingested by livestock, and second because alkaloids have distinctive taste characteristics. Thus, alkaloids may kill, injure, or reduce ...
