Abstract
Tetraacyldisaccharide 4′-kinase (LpxK) is the prime enzyme responsible for the biosynthesis of lipid A. LpxK is a key antibacterial drug target, but it is less exploitation in Pseudomonas aeruginosa and other bacterial species limits its therapeutic use. Pseudomonas aeruginosa is responsible for severe infections like pneumonia and urinary tract infections. The precautionary measures of Pseudomonas aeruginosa infections are decisive as it results in extensive drug resistance, systemic bacteremia, and ventilator-associated pneumonia. The current rational approach highlights exploiting the use of computer-aided drug design approaches to counter Pseudomonas aeruginosa specific LpxK. The various approaches used were exploring the metabolic pathway database (Metacyc), drug target validation using DEG, protein modeling, ligand docking, e-pharmacophore assisted virtual screening, physicochemical and Toxicity profile prediction studies, and molecular simulations in spotting out novel potential hits compounds. The virtual hits which have highly ranked in the study were STOCK4S-16119, STOCK1S −60869, STOCK6S −43621, STOCK6S −3328, and STOCKS-39892 which can act as a scaffold for the establishment of new hits against LpxK and can result in control of Pseudomonas aeruginosa infectivity.
