Piperazine Derivatives Attenuate Scopolamine‐Induced Memory Deficits by Modulating Neuroinflammation and Oxidative Stress via the NF‐κB/TNF‐α/COX‐2 Pathway

open access: yesChemistrySelect, Volume 10, Issue 25, July 4, 2025.
Piperazine derivatives 2b, 2f, and 2h reduce neuroinflammation, oxidative stress, and memory impairment by modulating COX‐2, p‐NF‐κB, and TNF‐α pathways, showing promise as lead compounds for neurodegenerative disease drug development. Abstract Oxidative stress‐induced neuro‐inflammatory events are common in neurodegenerative illnesses, addressing ...
