Abstract
Objective: Parkinson's disease (PD) and Alzheimer's disease (AD) are the most common forms of neurodegenerative disorders. The aim of the current work is to study the potential of some new indanone derivatives for the treatment of these neurological disorders.
Methods: A new series of 4-(2-oxo-2-aminoethoxy)-2-benzylidene substituted indanone derivatives have been synthesized and studied for anti-Parkinsonian and anti-Alzheimer's effects. Substitution of different aminoalkyl functionalities at the para position of 2-benzylidene moiety of indanone ring resulted in the formation of potent anti-parkinsonian and anti-Alzheimer's agents (5-10). The neuroprotective effects of newly synthesized compounds were evaluated using perphenazine (PPZ)-induced catatonia in rats and LPS-induced cognitive deficits in mice models. Further, in silico molecular modelling studies of the new indanone derivatives were performed by docking against the 3D structures of various neuroinflammatory mediators, such as interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and monoamine oxidase-B (MAO-B), to gain the mechanistic insights of their anti-Alzheimer's and antiparkinsonian effects.
Results: The newly synthesized indanone analogues 5-10 were found effective against PPZinduced motor dysfunction and LPS-induced memory impairment in animal models. Among all the synthesized analogues, morpholine-substituted indanone 9 displayed maximum anti-parkinsonian activity, even better than the standard drug L-DOPA, while pyrrolidine and piperidine substituted analogues 5 and 6 were found to be the most potent anti-Alzheimer's agents.
Conclusion: The new 2-arylidene-1-indanone analogues show good potential as promising leads for designing compounds against Parkinson's and Alzheimer's diseases.
