Аннотация
PURPOSE: The current study was conducted to develop and evaluate sialic acid grafted cationic myricetin (MY) fabricated nanostructured lipid carrier (Sia-Cat-MY-NLC) for Alzheimer's disease (AD) management.
METHODS: In-vitro amyloid beta aggregation inhibition and mitochondrial membrane potential of prepared NLCs were observed in SH-SY5Y cells. The transendothelial electrical resistance was measured through hCMEC/D3 cells. Pharmacokinetic and pharmacodynamic studies were conducted to evaluate neuropharmacokinetic parameters and levels of AD hallmarks in AD rats.
RESULTS: The optimized formulations showed particle sizes (142.26 ± 24.16 nm and 236.3 ± 15.26 nm), zeta potentials (36.5 ± 2.43 mv and -2.4 ± 1.30 mv) respectively for Cat-MY-NLC and Sia-Cat-MY-NLC. Prepared NLCs treatments revealed significant neuroprotective effects in SH-SY5Y cells followed by the ability to cross the in-vitro BBB model. Results of pharmacokinetic studies showed 5.3 and 5.88 folds enhanced bioavailability with Cat-MY-NLC and Sia-Cat-MY-NLC administration respectively.
CONCLUSIONS: The results of enzymatic analysis showed a significant (p < 0.05) restoration of AD hallmark levels in the brain after Sia-Cat-MY-NLC treatment than Cat-MY-NLC.
