Discovery of palmatine derivatives as potent neuroprotective agents

J Asian Nat Prod Res. 2024 Aug;26(8):910-917. doi: 10.1080/10286020.2024.2341927. Epub 2024 Apr 15.

Abstract

Alzheimer's disease is a neurodegenerative disorder characterized by the presence of neurodegenerative lesions and cognitive impairment. In this study, a series of novel palmatine derivatives were designed and synthesized through the introduction of a heteroatom using carbodiimide-mediated condensation. The synthesized compounds were then screened for toxicity and potency, leading to the identification of compound 2q, which exhibited low toxicity and high potency. Our findings demonstrated that compound 2q displayed significant neuroprotective activity in vitro, emerging as a promising candidate for Alzheimer's disease treatment.

Keywords: Alzheimer’s disease; neuroprotective; palmatine; synthesis.
