Molecular hybridization is a strategy to combine pharmacophores into a single molecule, resulting in enhanced activity and affinity. In this study, novel hybrids combining anticancer drug 5-fluorouracil with antioxidant coumarin derivatives were synthesized. These hybrids exhibited good antioxidant properties and the ability to form stable nanoparticles in aqueous media. They showed superior cytotoxicity against human pancreatic cancer cells compared to free 5-fluorouracil.
Molecular hybridization consists of the combination of two or more non-identical pharmacophores in a single molecule. It has emerged as a promising strategy that allows the design of molecular frameworks with enhanced activity and affinity compared to their parent drugs. In this work, two novel hybrids that combine the well-known anticancer chemotherapeutic agent 5-fluorouracil with antioxidant coumarin derivatives have been synthesized and characterized by means of a copper-catalyzed azide-alkyne cycloaddition (CuAAC). The conjugates showed good antioxidant properties and a high tendency to aggregate and form stable nanoparticles in aqueous media, with regular shape and uniform size. These materials have proven to be preferential cytotoxic agents in vitro against human pancreatic cancer cells PANC-1, with an activity superior to free 5-fluorouracil. These results open up the possibility of exploiting the synergistic combination between 5-fluorouracil and coumarin derivatives and warrant further investigation of these hybrids as promising pancreatic anticancer agents.
