The inducer of differentiation of human promyelocytic leukemia HL-60 cells is commonly accepted to have potential therapeutic importance. Verticinone, one of the major isosteroidal alkaloids from the bulbus of Fritillaria ussuriensis, was found to inhibit the growth of HL-60 cells by inducing these
Steroidal glycosides (1-18), including 10 new compounds (1-10), were isolated from the bulbs of Fritillaria meleagris (Liliaceae). The structures of the new compounds were determined by two-dimensional (2D) NMR analysis, and by hydrolytic cleavage followed by spectroscopic and chromatographic
BACKGROUND
Fritillaria thunbergii Miq. has been traditionally used in China as antitussive and expectorant herbs, and newly used in the clinical treatment of leukemia in recent years.
OBJECTIVE
To investigate whether gender exerted a significant influence on the pharmacokinetics, tissue distribution
Fritillaria thunbergii Miq. has been widely used in traditional Chinese medicine for its expectorant, antitussive, antiinflammatory and analgesic properties. Moreover, modern pharmacological studies have demonstrated that F. thunbergii Miq. has efficacy in the treatment of leukemia and cancers of
Although verticinone, a major alkaloid isolated from the bulbus of Fritillaria ussuriensis, has been shown to induce differentiation in human leukemia cells, the exact mechanism of this action is not completely understood in cancer cells. Verticinone was used to conduct growth and apoptosis-related
Four new steroidal alkaloids, puqienine A (1), puqienine B (2), N-demethylpuqietinone (3), and puqietinonoside (4), along with a known steroidal alkaloid, puqietinone, were isolated from the bulbs of Fritillaria puqiensis. The structures of these compounds were elucidated on the basis of
