kadsura coccinea/neoplasms

Kadsuraols A-C (1-3), which are tetrahydrocyclobutaphenanthrofuranone-type lignans with a new carbon skeleton comprising a four-membered ring across C-1'-C-8, have been isolated from the roots of Kadsura longipedunculata. Their structures and absolute configurations were unambiguously determined

Phytochemical investigation on the stems of Kadsura renchangiana led to the isolation of two new sesquiterpenoids, renchangianins F and G (1 and 2). Their structures were elucidated by spectroscopic methods, including 2D NMR techniques. The in vitro cytotoxic activities of the isolates were studied

A phytochemical study of Kadsura heteroclita led to the isolation of eight triterpenoids, including two new compounds, named kadheterilactone A (1) and kadheterilactone B (2), as well as six known compounds, longipedlactone H (3), longipedlactone A (4), longipedlactone F (5), kadsuranic acid A (6),

One new schiartane-type triterpene, heteroclitalactone N (1), and four known compounds (2-5), seco-coccinic acid F, dihydroguaiaretic acid, schizanrin F, and kadsuralignan B were isolated from the stems of Kadsura heteroclita. Their structures were determined by the combination of spectroscopic and

Ethnopharmacological relevance: Kadsura heteroclita stem (KHS) is a well-known hepatoprotective Tujia ethnomedicine (folk named Xuetong), has long been used for the prevention and treatment of hepatitis and liver diseases.
