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.
Three new dibenzocyclooctadiene lignans, kadusurain A-C (1-3), together with two known compounds kadsuphilin A (4) and B (5), were isolated from an EtOAc fraction of the 80 % acetone extract of Kadsura coccinea (Lem.) A. C. Smith. Their structures were established by 1D and 2D NMR techniques, and
Kadsura heteroclita Roxb. Craib. (Schisandraceae), is a vine plant mainly distributed in southwest part of China. A new dibenzocyclooctadiene lignan, kadsulignan W (1), along with eleven known lignans (2-12) were isolated from chloroform soluble fraction of stems of Kadsura
[structure: see text] Two novel triterpene dilactones with an unprecedented rearranged hexacyclic skeleton, kadlongilactones A (1) and B (2), have been isolated from the leaves and stems of Kadsura longipedunculata Finet et Gagnep (Schisandraceae). Their structures were established by comprehensive
[structures: see text] Three novel C19 homolignans, designated taiwankadsurins A (1), B (2), and C (3), were isolated from the aerial parts of Taiwanese medicinal plant Kadsura philippinensis. The structures of 1-3, which have a
Xuetonglactones A-F (1-6), six unreported highly oxidized lanostane- and cycloartane-type triterpenoids along with 22 known scaffolds (7-28) were isolated from the stems of Kadsura heteroclita (Roxb.) Craib. Compared with previous congeners, xuetonglactone A
Five 3,4-seco-cycloartane triterpenoids were isolated from the stems of Kadsura ananosma, two of which had rearranged 5/6 consecutive carbocycle rings C/D (trivially named ananosins A (1) and B (2)), one had a migrated CH3-18 (named ananosins C (3)), and two were analogs, ananosins D (4) and E (5).
Heilaohu, the roots of Kadsura coccinea, has a long history of use in Tujia ethnomedicine for the treatment of rheumatoid arthritis and gastroenteric disorders, and a lot of work has been done in order to know the material basis of its pharmacological activities. The chemical investigation led to
Rheumatoid arthritis (RA) is a chronic autoimmune diseased state, characterized by hyperplasia of the synovial membrane, degradation of cartilage, and bone erosion of diarthrodial joints. Kadsura heteroclita (Roxb) Craib (Schizandraceae), a traditional Tujia ethnomedicine called Xue
Fourteen new rearranged 6/6/5/6-fused triterpenoid acids, namely, kadcoccine acids A-N (1-14), were isolated from an EtOAc-soluble extract of the stems of Kadsura coccinea. Their structures were characterized mainly by analyzing 1D and 2D NMR and HRESIMS data and were shown to feature a rare
Phytochemical investigations of the stem of Kadsura heteroclita (Roxb) Craib (Schizandraceae) resulted in the isolation and structure elucidation of six new triterpenoidal compounds named heteroclitalactones A-E (1-5) as well as heteroclic acid (6) and heteroclitalactone F (7), which was isolated
