Abstract:We report the discovery and characterization of antioxidative effects of uridine linked with three dipeptide motifs against DNA oxidation induced by peroxyl radicals. First, the dipeptide motifs are constructed by using the Ugi four-component reaction (Ugi 4CR), in which caffeic, ferulic, sinapic, and syringic acids are used as the carboxylic acid resources, vanillin, benzaldehyde, and p-hydroxybenzaldehyde are used as the aldehyde resources, tyramine-and dopamine-related isocyanides as well as ethyl isocyanoa… Show more
