Nuevos derivados de purinas con actividad antiproliferativa y estudios de aminación reductora por biotransformación

Abstract

En la presente Tesis Doctoral se han diseñado, sintetizado y caracterizado tres familias de compuestos heterocíclicos y una de análogos abiertos, unidos a diferentes purinas sustituidas con halógenos (6-cloro, 2,6-dicloro, 6-bromo y 6-trifluorometilpurina), con posible aplicación como agentes antitumorales. Entre los derivados cíclicos se encuentran las familias de benzoxazinas, quinolinas y piridoxazinas. Los análogos abiertos poseen diferentes radicales en el grupo éster, habiéndose obtenido una serie con metilo y otra con etilo. Todas las moléculas se han ensayado frente a las líneas celulares de adenocarcinoma de mama humano MCF-7, melanoma humano A375, y cáncer colorrectal HCT-116. Se ha realizado un estudio de apoptosis al compuesto más activo. Se ha concluido que los derivados heterocíclicos son más activos que los análogos abiertos, que la distancia entre la base púrica y el heterociclo benzofusionado tiene una relación inversa con la actividad y por último, que los compuestos con 2,6-dicloropurina son los mas activos. En concreto el compuesto (3-((2,6-dicloro-9H-purina-9-il)metil-1-tosil-1,2,3,4-tetrahidroquinolina, ha resultado ser el más activo en las líneas celulares ensayadas, con un valor de CE50 de 2.8 ± 0.31μM en la línea HCT-116. Este derivado ha mostrado una inducción apoptótica a través de la activación de las caspasas 3/7 y ha producido baja citotoxicidad en las células no cancerígenas.
