Abstract

Due to the unclear pathogenesis of Alzheimer's disease (AD) and the lack of a completely cured medication, AD patients need to take medication in order and on time every day all one's life, which is difficult for severe memory impairment patients to strictly follow on time. Traditional AD drug carriers, such as sugar coating and capsules, rely on dissolution or fragmentation to achieve drug release, which lacks the interaction between drug molecules and carriers, thus they cannot achieve sufficient long-acting and sequential drug release. Herein, Mn-MOF-74, which ligand structure is similar to two antioxidants dihydroquercetin (DHQ) and resveratrol (Res) is chosen as the carrier. Due to the differences in adsorption energy between DHQ/MOF and Res/MOF, the release speed of DHQ is much faster than Res. Therefore, Mn-MOF-74 loaded with DHQ and Res (DR@MOF) showed sequential drug release and a long-term antioxidant effect for ≈72 h, with an efficacy time six times longer than that of vitamin E. In 5×FAD transgenic mice, DR@MOF exhibited excellent capacity in maintaining oxidative balance in the brain, ameliorating spatial learning and memory deficits, and showed the potential of an AD agent for long-acting and sequential treatment.
