Medchem Filtering Toolkit is a Python library offering drug-likeness heuristics, structural alert and PAINS filters, group detection, catalogs, and complexity scoring to triage compound libraries and prioritize leads in drug discovery workflows.

This powerful Python library provides comprehensive medicinal chemistry filters for compound triage in drug discovery. Users can apply established drug-likeness rules (like Lipinski's Rule of Five, Veber, and CNS rules), detect structural alerts (PAINS, NIBR), calculate complexity metrics, and filter molecular libraries using a custom query language. It is essential for prioritizing hit compounds and optimizing lead structures.
