Glycosylation of chrysin with β-d-glucose tetraacetate (LQFM280) enhances its in vitro and in vivo neuroprotective effects against the toxicity induced by 3-nitropropionic acid.

Chrysin (CHR) is a naturally occurring flavonoid found in the human diet, recognized for its potential in preventing neurodegenerative diseases. However, its limited water solubility restricts its bioavailability and therapeutic applications. To address this issue and bolster the neuroprotective properties of CHR for potential nutraceutical or medicinal use, we investigated a novel compound, LQFM280, formed by conjugating CHR with β-d-glucose tetraacetate.

Chrysin bonded to β-d-glucose tetraacetate enhances its protective effects against the neurotoxicity induced by aluminum in Swiss mice.

Objectives: To evaluate whether the glycosylation of chrysin (CHR) enhances its protective effects against aluminum-induced neurotoxicity.

Methods: To compare the antioxidant, anticholinesterase, and behavioral effects of CHR with its glycosylated form (CHR bonded to β-d-glucose tetraacetate, denoted as LQFM280), we employed an integrated approach using both in vitro (SH-SY5Y cells) and in vivo (aluminum-induced neurotoxicity in Swiss mice) models.

Key Findings: LQFM280 demonstrated higher antioxidant activity than CHR in both models.
