kadsura ananosma/leukemia

Five new 3,4-seco-lanostane-type triterpenoids, seco-coccinic acids G-K (1-5), and a known compound, seco-coccinic F, were isolated from the roots of Kadsura coccinea (Lem.) A. C. Sm. Their structures were elucidated by spectroscopic methods, including 2D-NMR and HR-MS techniques. The cell growth

Two DNA cleavage agents, meso-dihydroguaiaretic acid (1) and isobavachalcone (2) together with the known alpha-ylangene, beta-sitosterol, daucosterol, pentacosane, hexacosanic acid and cerotic acid 1-monoglyceride were isolated from the stem barks of Kadsura ananosma Kerr for the first time.

Two new 18(13-->12)-abeo-lanostane triterpenoid acids, ananosic acids B (1) and C (2), were isolated from the stems of Kadsura anaosma. Their structures were elucidated by spectral studies and chemical transformation. Compounds 1 and 2 were evaluated for cytotoxicity using CCRF-CEM leukemia cells

Seven new lanostane-type triterpenoids, seco-coccinic acids A-F (1- 6) and coccinilactone A (7), were isolated from the roots of Kadsura coccinea. Their structures were established on the basis of spectroscopic data analysis. The absolute configuration at C-24 of compound 5 was confirmed by the

Six new triterpene dilactones with a rare rearranged pentacyclic skeleton, longipedlactones K-P (1-6), and seven known analogues (7-13) were isolated from the stems of Kadsura ananosma. Compound 1 was found to possess a unique peroxide bridge between C-1 and C-9 in rings A and B. The structures of

Schisanlactone E (SE) is a bioactive ingredient extracted from the stem of Kadsura heteroclita (Roxb) Craib. SE has various pharmacological activity such as anti-tumor and anti-leukemia effects. However, its absorption, distribution, metabolism, and excretion have rarely been examined. In this
