El numero de posibles estructuras moleculares en el diseno de nuevos compuestos organicos es una cantidad tan grande que resulta dificil de imaginar. La sintesis y analisis de nuevas sustancias es un arduo y enormemente costoso trabajo que no siempre se ve recompensado con la obtencion de compuestos valiosos. Por este motivo la teoria QSAR/QSPR toma una notable importancia, ya que utilizandola se pueden predecir actividades y propiedades de practicamente cualquier sustancia, aun de aquellas no existentes o dificiles de analizar. De esta forma la teoria puede ser empleada para el diseno y optimizacion del proceso de obtencion de nuevas drogas. Los estudios QSAR/QSPR combinan metodos estadisticos con Quimica Computacional, para establecer modelos matematicos que cuantifiquen las relaciones entre la estructura molecular y la actividad o propiedad. Este libro introduce los principales conceptos en los que se basa esta teoria, mostrando ademas novedosos desarrollos en la obtencion de modelos lineales en QSAR/QSPR y sus aplicaciones en diversos campos de interes cientifico."

Biflavonoids comprise a group of the flavonoid family that possess a variety of structures and biological activities of high relevance, such as anticancer, antibacterial, antifungal, antiviral, anti-inflammatory, antinociceptive, antioxidant, vasodilator and anticlotting. The chemistry of biflavonoids is very important in many fields of research, especially because these compounds are structurally different bioactive molecules with potential for biomedical applications. This book highlights the structural biflavonoid variability, rearrangements and different stereochemistry through about 470 structures distributed in some species of Angiosperms, Gymnosperms, ferns and mosses.
