D-Penicillamine/Dihydroquercetin Dual-Loaded Metal-Organic Framework as a Microenvironment Copper Regulator for Enhancing the Therapeutic Efficacy of Polyphenolic Antioxidant in Alzheimer's Disease.

ABSTRACT: Polyphenols like dihydroquercetin, rutin, and rifampicin show promise for Alzheimer's disease (AD) therapy due to their ability to inhibit amyloid-β (Aβ) aggregation and reduce reactive oxygen species (ROS), garnering significant recent interest. However, their efficacy is substantially diminished because excess metal ions present in amyloid plaques can chelate these compounds. Therefore, reshaping the metal microenvironment in the patient's brain is particularly important for the therapeutic effect of AD. To address the above issues, we have constructed a composite system formed by NH₂-MIL-101(Fe) (MOF), dihydroquercetin (DHQ), and D-penicillamine (D-pen). Due to the lack of π-π interaction and the low adsorption energy between D-pen/MOF, the release order and speed of D-pen wa
