cerbera oppositifolia/悪性腫瘍

17βH-neriifolin, a cardiac glycoside compound had been successfully isolated from Cerbera odollam leaves based on bioassay guided isolation procedure. The compound was tested against breast (MCF-7, T47D), colorectal (HT-29), ovarian (A2780, SKOV-3) and skin (A375) cancer cell lines that gave IC50

Two new cardenolides, (-)-14-hydroxy-3beta-(3-O-methyl-6-deoxy-alpha-L-rhamnosyl)-11a lpha, 12alpha-epoxy-(5beta,14beta,17betaH)-card-20 (22)-enolide (1), (-)-14-hydroxy-3beta-(3-O-methyl-6-deoxy-alpha-L-glucopyranosyl)-11al pha,12alpha-epoxy-(5beta,14beta,17betaH)-card -20(22)-enolide (2), and a

A new cytotoxic cardenolide glycoside, 3beta-O-(2'-O-acetyl-alpha-L-thevetosyl)-14beta-hydroxy-7-en-5beta-card-20(22)-enolide, (7,8-dehydrocerberin), together with five known cardenolides, 17beta-neriifolin, deacetyltanghinin, tanghinin, cerberin and 2'-O-acetyl-cerleaside A were isolated from the

BACKGROUND Cerbera manghas L. (Apocynaceae) is a medicinal plant traditionally used to ameliorate the clinical signs of inflammatory diseases and hypertension. OBJECTIVE Although C. manghas L. has long been used as a traditional remedy for various diseases, the underlying molecular and cellular

Since reactive oxygen radicals play an important role in carcinogenesis and other human disease states, antioxidants present in consumable fruits, vegetables, and beverages have received considerable attention as cancer chemopreventive agents. Thus, in order to identify antioxidants in plant

A cardenolide glycoside, 3 beta-O-(2'-O-acetyl-l- thevetosyl)-15(14-->8)-abeo-5 beta-(8R)-14-oxo-card-20(22)-enolide (2'-O-acetyl cerleaside A), was isolated from a methylene chloride extract of the seeds of Cerbera odollam, together with four known compounds: cerleaside A, 17 alpha-neriifolin, 17

We report the isolation of two known iridoid glucosides theviridoside (1) and theveside (2) from the aqueous extract of leaves of Cerbera odollam and semi-synthetic derivatisation of theveside prepared in a single step under protection group-free conditions. Derivatives 2a-j were evaluated for
