The new beta-D-glucosidase in terpenoid-isoquinoline alkaloid biosynthesis in Psychotria ipecacuanha. [PDF]
Ipecac alkaloids produced in the medicinal plant Psychotria ipecacuanha such as emetine and cephaeline possess a monoterpenoid-tetrahydroisoquinoline skeleton, which is formed by condensation of dopamine and secologanin. Deglucosylation of one of the condensed products N-deacetylisoipecoside (1 alpha(S)-epimer) is considered to be a part of the ...

Is a metabolic enzyme complex involved in the efficient and accurate control of Ipecac alkaloid biosynthesis in Psychotria ipecacuanha? [PDF]
Ipecac alkaloids produced in the medicinal plant Psychotria ipecacuanha such as emetine and cephaeline possess a monoterpenoid-tetrahydroisoquinoline skeleton, which is formed by condensation of dopamine and secologanin. The condensation products are deglucosylated, and the resulting aglycon is further processed to protoemetine, which is condensed with

Three new O-methyltransferases are sufficient for all O-methylation reactions of ipecac alkaloid biosynthesis in root culture of Psychotria ipecacuanha. [PDF]
The medicinal plant Psychotria ipecacuanha produces ipecac alkaloids, a series of monoterpenoid-isoquinoline alkaloids such as emetine and cephaeline, whose biosynthesis derives from condensation of dopamine and secologanin. Here, we identified three cDNAs, IpeOMT1-IpeOMT3, encoding ipecac alkaloid O-methyltransferases (OMTs) from P. ipecacuanha.

Natural Plant Alkaloid (Emetine) Inhibits HIV-1 Replication by Interfering with Reverse Transcriptase Activity [PDF]
Ipecac alkaloids are secondary metabolites produced in the medicinal plant Psychotria ipecacuanha. Emetine is the main alkaloid of ipecac and one of the active compounds in syrup of Ipecac with emetic property. Here we evaluated emetine’s potential as an

A target enrichment probe set for resolving phylogenetic relationships in the coffee family, Rubiaceae. [PDF]
Abstract Premise Rubiaceae is among the most species‐rich plant families, as well as one of the most morphologically and geographically diverse. Currently available phylogenies have mostly relied on few genomic and plastid loci, as opposed to large‐scale genomic data.

Diferenciação morfológica e anatômica em populações de "ipecacuanha" - Psychotria ipecacuanha (Brot.) Stokes (Rubiaceae) [PDF]
Psychotria ipecacuanha e uma especie medicinal da familia Rubiaceae, importante pela producao em suas raizes do alcaloide emetina. Foram feitas analises das tres populacoes disjuntas que compoem a especie e que ocorrem na America Central (Nicaragua, Costa Rica e Panama) e Colombia, sul da Floresta Amazonica (Rondonia e Mato Grosso) e Mata Atlântica ...

Substratos alternativos para propagação vegetativa de Psychotria ipecacuanha (Brotero) Stokes
O objetivo deste estudo foi determinar entre diferentes substratos qual proporciona melhores condições para propagação vegetativa de ipeca via estaca de raiz, otimizando assim este processo para que se atenuem as limitações da produção em escala comercial da espécie. Foi estabelecido experimento em casa de vegetação, os segmentos de raiz de ipeca foram
