DrugSpaceX

DrugSpaceX provides a virtual compound library generated by transforming approved drug molecules to produce over 100 million novel, structurally diverse, three-dimensional, and synthesizable chemical structures for virtual screening and drug discovery.

Key Features:

• Enumeration from approved drugs: Generates over 100 million novel chemical structures by applying transformations to approved drug molecules.
• Structural novelty and diversity: Produces structurally novel and diverse compounds with extensive three-dimensional chemical space coverage.
• Synthesizability focus: Emphasizes generation of synthesizable compounds suitable for downstream medicinal chemistry.
• Downloadable subsets: Provides selectable subsets including a 10% diversity subset, an extended drug-like subset, a standard drug-like subset, a lead-like subset, and a fragment-like subset.
• Transformation annotation: Includes detailed transformation instructions and records the position of each transformation within molecules.
• Virtual screening-ready: Supplies compound collections intended for use in virtual screening workflows.
• Case study validation: Demonstrated identification of initial hit compounds for discoidin domain receptor 1 (DDR1) kinase.

Scientific Applications:

• Virtual screening: Use the enumerated library and subsets for in silico screening campaigns against biological targets.
• Hit identification and lead discovery: Support initial hit finding and progression toward lead compounds, as shown for DDR1 kinase.
• Ligand identification and optimization: Aid medicinal chemistry in ligand design, strategic planning, and protection-group considerations via transformation annotations.
• Subset-guided selection: Enable selection of compounds based on desired chemical properties using predefined subsets (diversity, drug-like, lead-like, fragment-like).

Methodology:

Enumerates novel compounds by applying expert-defined transformations to approved drug molecules, generates multiple downloadable subsets (10% diversity, extended drug-like, standard drug-like, lead-like, fragment-like), and records the position of each transformation within molecules.
