Identification of APOE4 modulators, targeted therapeutic candidates in Coronary Artery Disease, using Molecular Docking studies

Abstract

A significant genetic suspect for coronary artery disease is the pathological adaptation of apolipoprotein E4 (APOE4) through intramolecular interaction. With the prevailing evidences on APOE4 genotype and its prevalence in coronary artery disease, the present study has investigated the protein–ligand binding affinity and unveil the receptor binding abilities of different classes of ligands for APOE4 through molecular docking studies. Structural basis of APOE4 involvement in CAD suggests that the intramolecular domain interactions to be a suitable target for therapeutic intervention. Various classes of ligands including known drugs used in the treatment of CAD, fragment-based stabilizers and their similar structures and molecules with known bioactivity against APOE4 were screened for their binding affinity and further investigated for their interactions with APOE4. Computational studies show the benzyl amide derived structures to be useful candidates in modulation of APOE4. The dynamics of the binding analysis can be further achieved with an in-depth understanding of drug-receptor interactions performing molecular dynamic simulation studies.
