Design, synthesis, and neuroprotective activity of salidroside-based dual inhibitors of selective monoamine oxidase B and amyloid-β aggregation
摘要
This study focuses on the design, synthesis, and evaluation of a series of salidroside derivatives (pOBZ-1~pOBZ-11) for their potential as inhibitors of monoamine oxidase B (MAO-B) and amyloid beta (Aβ42) aggregation, and neuroprotective agents. Among the synthesized derivatives, pOBZ-1 and pOBZ-2 exhibited superior MAO-B inhibitory activity compared to salidroside, with notable selectivity over MAO-A. These compounds demonstrated linear competitive inhibition. Additionally, the derivatives effectively inhibited Aβ42 aggregation and protected SH-SY5Y cells from Aβ42 and hydrogen peroxide (H2O2)-induced neurotoxicity. The findings suggest that pOBZ-2, in particular, holds promise as a therapeutic candidate for Alzheimer’s disease.
