Anti-Alzheimer activity of new coumarin-based derivatives targeting acetylcholinesterase inhibition.

ABSTRACT: New 2-oxo-chromene-7-oxymethylene acetohydrazide derivatives 4a-d were designed and synthesized with a variety of bioactive chemical fragments. The newly synthesized compounds were evaluated as acetylcholinesterase (AChE) inhibitors and antioxidant agents in comparison to donepezil and ascorbic acid, respectively. Compound 4c exhibited a promising inhibitory impact with an IC₅₀ value of 0.802 μM and DPPH scavenging activity of 57.14 ± 2.77%. Furthermore, biochemical and haematological studies revealed that compound 4c had no effect on the blood profile, hepatic enzyme levels (AST, ALT, and ALP), or total urea in 4c-treated rats compared to the controls. Moreover, the histopathological studies of 4c-treated rats revealed the normal architecture of the hepatic lobules and renal pa
