“…Notably, reactions summarized in Tables 2 and 3 appear to have a rather broad scope with respect to substituents in the aromatic groups originating from either the aldehyde or the aniline. In fact, the scarce examples of similarly diarylsubstituted CCR-derived lactams reported in the literature [14][15][16] only include electron-neutral and electron-rich aromatic groups. In this study, similar reaction yields were obtained for diverse substitution patterns, including electronwithdrawing substituents in either portion of the imine partner (or even both portions as in 7l).…”

“…Se ha comprobado en muchas investigaciones el efecto espermicida de extractos vegetales en animales vertebrados e invertebrados de estructura similar a los sesquiterpernos como los aislado de la esponja marina Geodesia que inhibe la motilidad espermática del Tetrapygus niger mediante la supresión de la lanzadera de la fosfoqueratinasa que afecta directamente a la dineína ATPasa (Ohta et al, 2008); el sesquiterpeno aislado del alga Laurencia claviformis presenta una inhibición en la citokinesis de los espermatozoides de Tetrapygus niger hacia los ovocitos (Rovirosa et al, 1999); en Mus musculus se reportó inmovilización espermática en un 100% así como una considerable disminución de viabilidad con el ex- Sin embargo fueron Prakash et al, 2013 los primeros en reportar sobre la actividad espermicida de algas sobre espermatozoides humanos, generando una inquietud acerca del uso de estos metabolitos en el ámbito de la contraceptividad.…”
