Abstract

Although the cure of amyloid related neurodegenerative diseases, non-neuropathic amyloidogenic diseases and non-neuropathic systemic amyloidosis are appealing energetic research attempts, beneficial medication is still to be discovered. There is a need to explore intensely stable therapeutic compounds, potent enough to restrict, disrupt or wipe out such toxic aggregates. We had performed a comprehensive biophysical, computational and cell based assay, that shows Nordihydroguaiaretic acid (NA) not only significantly inhibits heat induced hen egg white lysozyme (HEWL) fibrillation but also disaggregates preformed HEWL fibrils and reduces the cytoxicity of amyloid fibrils as well as disaggregated fibrillar species. The inhibitory potency of NA was determined by an IC50 of 26.3 μM. NA was also found to effectively inhibit human lysozyme (HL) fibrillation. NA interferes in the amyloid fibrillogenesis process by interacting hydrophobically with the amino acid residues found in highly prone amyloid fibril forming region of HEWL as explicated by molecular docking results. The results recommend NA as a probable neuroprotective and promising inhibitor for the therapeutic advancement prospective against amyloid related diseases.
