Unlabelled: Alzheimer's disease is one of the most common neurodegenerative disorder afflicting a large mass of population. BACE-1 (β-secretase) is an aspartyl protease of the amyloidogenic pathway considered responsible for Alzheimer's disease (AD). Since it catalyzes the rate-limiting step of Aβ-42 production from amyloid precursor protein (APP), its inhibition is considered a viable therapeutic strategy.

The derivatives were designed based on the docking simulation study, synthesized and assessed for BACE-1 inhibition in vitro. The designed ligands revealed desired binding interactions with the catalytic aspartate dyad and occupance of S1 and S2' active site regions.

Herein, we report a novel class of allylidene hydrazinecarboximidamide derivatives as moderately potent BACE-1 inhibitors, having aminoguanidine substitution on allyl linker with two aromatic groups on either side. A library of derivatives was designed based on the docking studies, synthesized and evaluated for BACE-1 inhibition in vitro.

Recently, reactive gliosis, which involves alterations in functioning and phenotype of different glial cells, has been implicated in Alzheimer's Disease (AD). Studies have revealed that astrocyte response to gross tissue damaging injury leads to anisomorphic astrogliosis reinforcing a cascade of events, eventually increasing the pathogenesis of AD and many other neurodegenerative disorders.
