Antibacterial activity of indole alkaloids from Aspidosperma ramiflorum.
We evaluated the antibacterial activities of the crude methanol extract, fractions (I-V) obtained after acid-base extraction and pure compounds from the stem bark of Aspidosperma ramiflorum. The minimum inhibitory concentration (MIC) was determined by the microdilution technique in Mueller-Hinton broth. Inoculates were prepared in this medium from 24-h broth cultures of bacteria (10(7) CFU/mL)....
متن کامل¹H and ¹³C-NMR data of the simplest plumeran indole alkaloids isolated from Aspidosperma species.
Indole alkaloids are the chemotaxonomic markers of the Aspidosperma genera. Those that have the simplest plumeran skeleton are classified as the precursors of biosynthetic routes and the intermediates for several synthetic reactions. This work aims to review the ¹H and ¹³C-NMR data, up to 2011, describing the skeleton of 35 different plumeran indole alkaloids, from a group of 46 of them, and hi...

متن کاملSpruceanumines A and B, Novel Plumeran Indole Alkaloids from Aspidosperma spruceanum (Apocynaceae)
Dois novos alcalóides indólicos com esqueleto plumerano, spruceanuminas A (1) e B (2), e oito alcalóides indólicos conhecidos, aspidospermidina (3), desmetoxipalosina (4), aspidocarpina (5), aspidolimina (6), fendlerina (7), aspidolimidina (8), obscurinervidina (9) e obscurinervina (10), foram isolados do extrato metanólico das cascas do caule e sementes de Aspidosperma spruceanum. As estrutura...
متن کاملIndole alkaloids from Aspidosperma rigidum and A. schultesii and their antiparasitic effects.
Five oxindole alkaloids, three plumerane-type alkaloids, subtype haplophitine, and one aspidospermatane-type alkaloid, subtype tubotaiwine, were isolated from the medicinal plants Aspidosperma rigidum and A. schultesii. One compound was identified as the transoid conformer of 18-oxo-O-methylaspidoalbine which was not previously described. The antiparasitic activity of all compounds against Tryp...
