Generate a user-defined number of novel molecules starting from any valid, drug-like structure(s), enabling comprehensive SAR exploration, analog generation, library expansion, and scaffold hopping. ## Controlled Data Generation Generate a user-defined number of novel molecules starting from any valid, drug-like structure(s). Faraday supports multiple approaches to molecular generation, allowing you to explore chemical space in a controlled and systematic manner. Key capabilities include: * **SAR exploration** – Generate analogs to understand structure-activity relationships * **Analog generation** – Create similar molecules with desired modifications * **Library expansion** – Scale up your compound collections efficiently * **Scaffold hopping** – Explore alternative core structures with similar properties * **User-defined quantities** – Generate exactly the number of molecules you need * **Drug-like filtering** – Ensure generated molecules meet pharmaceutical standards **Sample prompts:** * Generate 50 analogs of \[SMILES string] * Create a library of 100 molecules similar to aspirin * Generate scaffold hops for this compound: \[SMILES] * Expand my dataset with 200 drug-like molecules based on these structures * Create analogs with improved solubility for \[compound name] * Generate diverse molecules for SAR exploration around this hit: \[SMILES] ## Example:
