   2. Determine the ideal ranges for each parameter based on established guidelines for drug candidates (e.g., molecular weight < 500 Da, logP between 2 and 5, high solubility).
   3. Ensure that the defined criteria align with the therapeutic area and the specific target, as different types of drugs may have different requirements for drug-likeness.
2. Step 2: Computational Assessment of Drug-Likeness
   1. Use computational tools to predict the drug-likeness of lead compounds. Commonly used tools include ChemDraw, ADMET Predictor, and Lipinski’s Rule of Five, which evaluate molecular properties such as solubility, lipophilicity, and polarity.

   • Mol. weight ≤ 500 Da
   • LogP ≤ 5
   • No more than 5 hydrogen bond donors
   • No more than 10 hydrogen bond acceptors
   2. Check if the compound violates any of the rules and make adjustments to the molecular structure if necessary to improve drug-likeness.
5. Step 5: Drug-Likeness Optimization
   1. Optimize the compound structure based on the drug-likeness assessment. Modify functional groups, adjust molecular weight, and optimize solubility and lipophilicity to meet ideal parameters for drug development.
   2. Ensure that modifications do not significantly alter the biological activity of the compound. Use structure-activity relationship (SAR) analysis to guide the optimization process.
   3. Iteratively assess drug-likeness after each modification, repeating computational predictions and experimental validation as needed.
6. Step 6: Documentation and Reporting
   1. Document all steps of the drug-likeness assessment process, including computational predictions, experimental data, and optimization results.
   2. Prepare a Drug-Likeness Assessment Report that includes detailed information on the criteria used, predictions made, experimental validation results, and any modifications to the compound.
