In silico investigation of potential interleukin-8 (IL-8) and Cathelicidin (LL-37) inhibitors for rosacea treatment
Abstract
Emerging clinical observations underscore the correlation between interleukin-8 (IL-8) and rosacea. Increased IL-8 expression has been detected in rosacea samples, particularly in moderate to severe manifestations. This phenomenon has prompted the exploration of IL-8 as a prospective therapeutic target for rosacea treatment. To this end, a selection of compounds sourced from the ZINC database, encompassing six small molecules, was made with the intent of identifying promising lead candidates that exhibit drug-like characteristics against IL-8. Through an integrated in silico approach involving structure-guided drug design, encompassing molecular docking, molecular dynamics (MD) simulation, molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) analysis, protein-peptide docking, and scrutiny of toxicity profiles, it was ascertained that the small molecule ZINC000022339916 effectively inhibits IL-8 activity. These findings present a novel lead compound that warrants further validation through in vitro, in vivo, and ongoing clinical investigations to confirm its potential for therapeutic management of rosacea.
