expertise.
The enzymatic target proprotein convertase subtilisin/kexin type 9 (PCSK9) is critically involved in
the regulation of the lipoprotein metabolism leading to the degradation of low-density lipoprotein
receptors (LDLRs) upon binding. Drugs that lower LDL cholesterol (LDL-C) through the inhibition
of PCSK9 are useful in the management of hypercholesterolemia which greatly reduces the associated
risk of atherosclerotic cardiovascular disease (CVD). In 2015, anti-PCSK9 monoclonal antibodies
(mAbs), alirocumab and evolocumab were approved but owing to their high costs their prior
authorization practices were impeded, reducing their long-term adherence. This has drawn
considerable attention for the development of small-molecule PCSK9 inhibitors. In this research
work, novel and diverse molecules with affinity towards PCSK9 thereby having ability to lower
cholesterol. A hierarchical multistep docking was implemented to identify small molecules from
chemical libraries with a score cutoff ?8.00 kcal/mol, thereby weeding all the non-potential
molecules. A set of seven representative molecules have been identified from a comprehensive
computational study which included assessment of pharmacokinetics and toxicity profiles and binding
interactions along with in-depth analysis of structural dynamics and integrity using prolong molecular
dynamics (MD) simulation (in-duplicate). Furthermore the binding affinity of these PCSK9 inhibitory
candidates molecules was ascertained over 1000 trajectory frames using MM-GBSA calculations. The
molecules reported herein are propitious candidates for further development through necessary
experimental considerations
