galipea/alkaloid

An antileishmanial activity of quinolinic alkaloids from Galipea longiflora Krause, known as Evanta, has been demonstrated. We have previously shown that, apart from its leishmanicidal effect, in vitro pretreatment of spleen cells with an alkaloid extract of Evanta (AEE) interfered with the

Galipea officinalis Hancock is a shrubby tree reputed in folk medicine for its many properties which may be related to its alkaloid composition. We present in this paper the structural elucidation of five quinoline alkaloids: cuspareine, cusparine, and galipine, that have been previously described,

Galipea officinalis Hancock, a Venezuelan shrubby tree which is acclaimed in folk medicine for its many healing properties, is the only species of the genus to contain tetrahydroquinoline alkaloids. A GC-MS method has been developed in order to analyse the essential oil, hexane and chloroform

2-Aroylmethylidene-1,2,3,4-tetrahydroquinolines with the appropriate substituents can be suitable precursors for the synthesis of alkaloids from Galipea officinalis (cuspareine, galipeine, galipinine, angustureine). However, only two, rather low-yielding procedures for their synthesis are described

Traditional medicine and scientific studies have shown that the raw extract of Evanta [Galipea longiflora, Angostura longiflora (Krause) Kallunki] exhibits anti-leishmanial activity. We hypothesized that the healing observed when using this plant might not only be due to the direct action on the

Synthesis of an antileishmanial alkaloid and related compounds by using various epoxide-forming reactions is described.

Alkaloids obtained from the plant Evanta have been shown to have dual effects in Leishmania infection; a direct leishmanicidal effect on the parasite and more importantly, the alkaloids affect both polyclonal and Leishmania-specific stimulation of T-cells. Dendritic cells (DCs) play a pivotal role

The activity of an ethanolic extract of Galipea officinalis bark against Mycobacterium tuberculosis was shown to reside mainly in the basic alkaloidal fraction although the major part of the alkaloids present were in the neutral fraction. Six alkaloids were isolated from the bark including two other

BACKGROUND We previously described the gastroprotective effect of 2-phenylquinoline (2-PQ), the main alkaloid isolated from the bark of Galipea longiflora (Rutaceae). However, despite the significant and promising results, the pharmacological mechanisms of the gastroprotection induced by 2-PQ have

The quinolinium chloride salt of 8-hydroxyqinolinecarbaldehyde (2-Formyl-8-hydroxy-quinolinium chloride) was prepared as Galipea longiflora alkaloid analogue and its anticancer activity was evaluated both in vitro and in vivo. This chloride salt was found to show certain degree of selectivity

The preparation of chiral tetrahydroquinolines using Ir-catalysed asymmetric hydrogenation and their possible cytotoxic potential anti-cancer activity were reported. Both of the in vitro cytotoxicity assay on a series of human cancer cell lines including A549 small cell lung cancer, MDA-MB-231

As part of our continuing search for bioactive natural products from plants, the present study was carried out in order to evaluate the gastroprotective properties of alkaloid extract and 2-phenylquinoline obtained from the bark of Galipea longiflora (Rutaceae). Anti-ulcer assays were performed

The present study evaluated the antinociceptive properties of an alkaloid extract and 2-phenylquinoline obtained from the bark of Galipea longiflora Krause (Rutaceae) against different models of pain in mice. The results demonstrate that the alkaloid extract caused a pronounced antinociceptive

The isolation of N-methyl-4-hydroxy-3-(2',3'-epoxyisobutyl)-2-quinolone (1), a new natural compound, and candicine (2) from Galipea officinalis trunk bark is reported. This is the first report of candicine in the genus Galipea.

The antimalarial and toxicological properties of four tetrahydroquinoline alkaloids from Galipea officinalis trunk bark were studied. Crude extracts and pure alkaloids were tested for in vitro antimalarial activity on Plasmodium falciparum. The IC50 were evaluated after 24 and 72 h contact between
