VEGA ZZ 3.1

VEGA ZZ is a free molecular modeling and visualization platform developed by the Istituto di Chimica Farmaceutica e Tossicologica “Pietro Pratesi,” Università degli Studi di Milano. Designed for medicinal chemistry, cheminformatics, and computational chemistry workflows, it helps users build, edit, and inspect 3D molecular structures, analyze geometry and basic physicochemical properties, and convert among numerous chemical and biomolecular file formats. VEGA ZZ supports high-quality visualization, precise measurements, structure cleanup utilities, and automation through scripts and plug-ins, making it a practical hub for preparing datasets and interfacing with third-party simulation tools in both academic and industrial research.

Key capabilities:

• Interactive 3D visualization for small molecules and biomolecules
• Structure building, editing, protonation assistance, and geometry cleanup
• Broad file format import/export for chemical and structural data
• Measurement tools for distances, angles, and torsions
• Batch processing and workflow automation via scripting
• Extensible architecture and interoperability with external modeling engines
• Suited to ligand preparation, dataset curation, and early-stage modeling in drug discovery and toxicology
