Abstract

Background:

BACE-1 is an aspartate protease that is responsible for the proteolysis of amyloid precursor proteins (APP) into beta-amyloid (Aβ), a neurotoxic peptide in patients with Alzheimer's disease (AD). As such, BACE-1 is a prime pharmacological target in the control of Aβ in the brain and its inhibition will be a sound approach in AD therapy.

Methods:

The computational pipeline which comprised molecular docking (MD), Quantitative Structure Activity Relationship (QSAR) modelling and Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) studies enabled the prediction of molecular interaction and relative inhibitory potentials of the hit compound.

Results And Discussion:

The current study reports a naturally sourced small molecule inhibitor of BACE1 (C000000956) which was obtained through a computational pipeline. Also, pharmacological constraints such as pH dependent activity of the enzyme and blood brain barrier permeation which have been associated with the efficacy of previous BACE-1 inhibitors were well catered for. Our results suggest that orally delivered C000000956 is a potential small molecule inhibitor of BACE-1 which may find usefulness in AD-therapy.

Eukaryotic Transcription Inhibitors

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a...

Molecular Shapes

Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.
