Alternative Title
Antimitotic capacity in extracts of marine sponges from Colombian Caribbean.
Abstract
La determinación de actividad antimitótica de extractos de organismos marinos genera expectativas para la obtención de sustancias con potencial anticancerígeno a partir de fuentes alternativas. Se evaluó la actividad antimitótica in vitro de extractos orgánicos crudos de 15 esponjas de la costa Caribe colombiana, en embriones del erizo de mar Lytechinus variegatus. El 80% de las especies (Spirastrella coccinea, Myrmekioderma rea, Iotrochota imminuta, Halichondria sp., Petromica ciocalyptoides, Cinachyrella kuekenthali, Biemna cribaria, Oceanapia peltata, Xestospongia proxima, Oceanapia bartschi, Polymastia tenax y Dragmacidon reticulata) mostró un nivel de actividad fuerte inhibiendo la divisiones mitóticas desde el primer estadio celular durante la división de los huevos fertilizados de este erizo. Los extractos de Halichondria sp., P. ciocalyptoides y X.proxima desintegraron los núcleos celulares instantáneamente. El extracto de Cribrochalina infundibulum resultó medianamente activo; mientras que los extractos de las esponjas Desmapsamma anchorata y Myrmekioderma gyroderma no mostraron actividad.
The determination of antimitotic activity of organic extracts from marine organisms generates expectations on the isolation of substances with potential anticancer activity. The antimitotic activity of crude organic extracts from 15 marine sponges from the Colombian Caribbean coast were tested in vitro against embryos of the sea urchin Lytechinus variegatus. 80% of the species evaluated (Spirastrella coccinea, Myrmekioderma rea, Iotrochota imminuta, Halichondria sp., Petromica ciocalyptoides, Cinachyrella kuekenthali, Biemna cribaria, Oceanapia peltata, Xestospongia proxima, Oceanapia bartschi, Polymastia tenax y Dragmacidon reticulata) showed significant levels of inhibiting activity on the mitotic divisions at the first cellular phase of fertilized eggs. The extracts from Halichondria sp., P. ciocalyptoides and Xestospongia proxima disintegrate the cellular nuclei instantly. Extracts from Cribrochalina infundibulum showed an intermediate level of activity, while extracts from Desmapsamma anchorata and Myrmekioderma gyroderma showed no activity.
