quassia orinocensis/抗がん剤

Of the five quassinoids isolated from the root bark of Hannoa klaineana, only 15-desacetylundulatone was found active against P388 mouse lymphocytic leukemia cells and colon 38 adenocarcinoma. Undulatone and especially 15-O-beta-D-glucopyranosyl-21-hydroxy-glaucarubolone were found to be more toxic

A new quassinoid, designated 2'-(R)-O-acetylglaucarubinone (1), and seven known quassinoids (2-8) were isolated, using bioactivity-guided separation, from the bark of Odyendyea gabonensis (Pierre) Engler [syn. Quassia gabonensis Pierre]. The structure of 1 was determined by spectroscopic analysis

Samadera indica Gaetrn (Simaroubaceae) is claimed to possess various pharmacological activities like antioxidant, antifungal, antitumor, antiviral, and so on, but its taste is bitter. The aim of the present study is to investigate the toxicity of the methanolic extract and to develop suitable herbal

An investigation of the leaves of the Madagascan Simaroubaceae Samadera madagascariensis has yielded three C18 quassinoids, 5beta,6-dihydrosamaderine A, 2-chlorosamaderine A, and samaderolactone A, and a C19 quassinoid, 3,4beta-dihydrosamaderine C, together with the known quassinoids samaderine A,

BACKGROUND Simalikalactone E (SkE) from Quassia amara, has been proved to be a valuable anti-malarial and anti-cancer compound. As SkE is very scarce, methods of quantitation are needed in order to optimise its isolation process and to determine pharmacokinetic data. OBJECTIVE To validate methods
