Isovaleramida, principio anticonvulsivo aislado de Valeriana pavonii

Abstract: Introducción. El fraccionamiento fitoquímico de Valeriana pavonii, especie vegetal nativa utilizada tradicionalmente en Colombia con fines tranquilizantes, condujo al aislamiento e identificación de la isovaleramida, uno de los principios responsables de su actividad sobre el sistema nervioso central como anticonvulsivo. Objetivo. Reportar la identificación de la isovaleramida, metabolito de V. pavonii activo sobre el sistema nervioso central. Materiales y métodos. La purificación de la isovaleramida se realiz… Show more

“…It is possible that other compounds present in the extracts, or the interaction of various compounds are mainly responsible for the effectiveness of valerian extracts to delay the onset of seizure in fish. Two valerian species that do not contain valerenic acid, V. edulis and V. pavoniis, also have anticonvulsant properties [ 55 57 ].…”

“…Isovaleramide when administered at 100 mg/kg p.o., showed 90% protection against the maximal electroshock seizure in mice (MES), comparable to sodium phenytoin at 20 mg/kg, p.o. (100% protection) (Giraldo, 2010). Khom et al (2007) identified the sesquiterpene valerenic acid as a potent subunit specific modulator of GABA A receptors.…”

“…For valerian Valeriana officinalis there is a strong body of in vitro (Yuan et al, 2004;Ortiz et al, 2006;Torres-Hernanadez et al, 2007) and in vivo (Giraldo, 2010) experimental evidence which suggests that some efficacy might be expected. Khom et al (2007) identified the active constituent as valerenic acid.…”

“…Valerian pavonii: Fractioning of an extract of Valeriana pavonii, a native species used in Colombian folk medicine as tranquilizer, led to the isolation and identification of isovaleramide, one of the active constituents responsible for its CNS activity as anticonvulsant. Isovaleramide is one of the active anticonvulsant constituents of V. pavonii, for the first time reported in this species (Giraldo et al, 2010).…”
