A novel synthetic derivative of biaryl guanidine as a potential BACE1 inhibitor, to treat Alzheimer's disease: In-silico, in-vitro and in-vivo evaluation. | LitMetric
BACE1 enzyme has been known a potential target involved in Alzheimer's disease (AD). Present research was focused on the principles of virtually screening, chemical synthesis and protease inhibitory effect of BACE1 enzyme via biaryl guanidine derivatives. In-silico based paradigm (ligand binding interaction within active domain of BACE 1 enzyme i.e., aspartate Asp32 and Asp228) a novel compound was synthesized and subsequently subjected to in-vitro and in-vivo evaluation. 1,3-di(isoquinolin-6-yl) guanidine was synthesized and found potent (IC 6±0.56 µM) and active to arrest (99 %) β-secretase enzyme (FRET assay). Furthermore, it was found to improve novel object recognition test (RTI =56.55%) and Morris water maze test (32.26±3.45s) significantly (p<0.05). Enhanced pharmacokinetics and related properties (high iLOGP and Log S =-3.98) along with improved permeation to the blood brain barrier (BBB) (zero Lipinski violation) made it feasible to inhibit BACE1 as a novel therapeutic source to treat AD in future.
