ADME Druglikeness Tool

This tool computes physicochemical and ADME-relevant metrics from a molecule input to support medicinal chemistry and early drug discovery teams. It returns standardized values such as molecular weight, logP, logS, TPSA, HBD/HBA counts, rotatable bonds, and aromatic ring count. Rule-based flags for Lipinski, Veber, Ghose, and Egan assist in fast candidate filtering. The approach emphasizes reproducibility and comparability across libraries, enabling objective ranking of compounds before synthesis.

Conceptually, the tool applies established chemoinformatics calculations: MW from atomic weights; logP and logS from fragment-based models; TPSA from polar fragments; and simple counts for donors, acceptors, and rotatable bonds. Outputs include numeric values with standard units and categorical flags indicating rule compliance. Optional features add consensus solubility predictions, PAINS screening, and a basic synthetic accessibility estimate. These outputs support decision-making in library design and lead optimization, not clinical forecasting.

Who benefits include medicinal chemists, CROs, and academic researchers performing early screening and lead prioritization. The tool differentiates itself with open, transparent calculations, straightforward data exports, and alignment to common medicinal chemistry conventions, enabling rapid comparisons across compounds. It serves as a guideline for go/no-go decisions and risk assessment during preclinical planning.
