Description

The project aims to computationally optimize an in-house chemical series of small molecules targeting Xylella fastidiosa. These compounds bind a selected protein target and inhibit bacterial growth and biofilm formation but also affect beneficial endophytic bacteria. The objective is to improve selectivity toward Xylella fastidiosa while minimizing off-target effects. The candidate will assess target conservation across Xylella and representative endophytes through sequence and structural analyses, generating AlphaFold models when needed. Structure-and ligand-based approaches, including binding-site analysis, induced-fit docking, molecular dynamics simulations and MD-derived pharmacophore/Dynophore models, will identify selectivity determinants. Computational tools will support data analysis, prioritization and structure-activity relationships (SAR). New analogues will be designed considering xylem mobility and environmental safety, for subsequent synthesis and validation.
