Líneas de Investigación

Nuestro grupo se dedica a la formulación de estudios cuantitativos de relación estructura actividad (QSAR), con el fin de obtener modelos validados para el diseño de nuevos compuestos bioactivos (fármacos) que sean prometedores para el tratamiento de patologías humanas de relevancia.

En los estudios QSAR se busca correlacionar las propiedades fisicoquímicas de una serie de compuestos con sus actividades biológicas, con el fin de crear ecuaciones útiles para el diseño de nuevas moléculas (Figura 1), o para explicar retrospectivamente el comportamiento de los compuestos y sus mecanismos

de acción.

Figura 1. Esquema que representa la formulación de un estudio QSAR.

Actualmente hemos desarrollado y publicado modelos para varias patologías, mostramos algunas en la tabla siguiente.

Dentro de los métodos empleados, hemos utilizado técnicas clásicas de Hansch, análisis de Free-Wilson, hemos creado modelos combinados, utilizando descriptores cuánticos y topológicos, además de la generación de modelos 3D-QSAR (CoMFA, CoMSIA) que permiten una visualización simple y directa de los resultados a través de mapas de contorno. En la siguiente figura se muestra el resultado de mapas de contorno estéricos y electrostáticos obtenidos para heterociclos benzimidazoles estudiados por su capacidad de unión a los receptores de cannabinoides (Figura 2).

Figura 2. Mapas 3D-QSAR. Los resultados obtenidos para ligandos cannabinoides con afinidad CB1 y CB2 nos han permitido conocer los requisitos estructurales necesarios para conseguir selectividad para uno u otro tipo de receptor.
