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
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
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
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 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
Two novel acridone alkaloids, cuspanine [1] and cusculine [2], were isolated from the CH2Cl2 extract of the leaves of Angostura paniculata (Rutaceae). Their structures were established as 1-hydroxy-2,3,5,6-tetramethoxy-9-acridone for 1 and 1,2,3,5,6-pentamethoxy-9-acridone for 2 by means of
The active compounds obtained from some medicinal plants used traditionally worldwide for the treatment of leishmaniasis are reviewed. Among these active molecules, described in recent literature are quinoline alkaloids such as alkyl-2 quinoline and aryl-2 quinoline from Galipea longiflora,
