abuta fluminum/alkaloid

Three alkaloids were isolated from the bark of the traditional medicinal plant Abuta grandifolia (Mart.) Sandw. (Menispermaceae) and tested for in vitro anti-plasmodial activity. Two of them were identified as the Type VIII bisbenzylisoquinoline alkaloids, krukovine (1) and limacine (2), while the

A phytochemical investigation of Abuta rufescens was performed to authenticate plant material reported previously and to assess the cytotoxicity of the alkaloids obtained from the plant. Three alkaloids which have not previously been reported from this species, two phenolic (subsessiline, an

From Abuta grisebachii Triana & Planchon, Menispermacea used by Sanama tribe for the preparation of curare, five bisbenzylisoquinoline alkaloids have been isolated; four of them are tertiary (peinamine and three new alkaloids, 7-O-demethylpeinamine, N-methyl,7-O-demethylpeinamine and macolidine) and

Natural products obtained from species of the genus Abuta (Menispermaceae) are known as ethnobotanicals that are attracting increasing attention due to a wide range of their pharmacological properties. In this study, the alkaloids stepharine and 5-N-methylmaytenine were first isolated from branches

The phytochemical study of the stem bark and wood of Abuta grandifolia (Mart.) Sandwith led to the identification of four bisbenzylisoquinoline alkaloids (BBIQs), namely (R,S)-2 N-norberbamunine (1), (R,R)-isochondodendrine (2), (S-S)-O4″-methyl, Nb-nor-O6'-demethyl-(+)-curine (3), and

Oncogenic activation of the KRAS gene via point mutations occurs in 20-30% of patients with non-small cell lung cancer (NSCLC). The RAS-RAF-ERK and RAS-PI3K-AKT pathways are the major hyper-activated downstream pathways in RAS mutation, which promotes the unlimited lifecycle of cancer cells and

Antimalarial activity of 10 vegetal extracts (9 ethanolic extracts and 1 crude alkaloid extract), obtained from eight species traditionally used in Colombia to treat malaria symptoms, was evaluated in culture using Plasmodium falciparum chloroquine resistant (FcB2) strain and in vivo on rodent
