Percepta: Screening fragment‑like vs lead‑like properties in early design

Description
Early discovery often differentiates “fragment‑like” molecules from “lead‑like” or “drug‑like” ones based on simple property ranges. Percepta predictions can help classify proposed structures roughly along these lines.

Solution

1. For each proposed compound, obtain Percepta predictions (or input data) for:
   • Molecular weight.
   • logP/logD.
   • H‑bond donors and acceptors (if accessible in your setup).
   • Rotatable bond count (if accessible).
2. Apply internal fragment‑like and lead‑like rules (examples, to be tailored):
   • Fragment‑like: low MW, low lipophilicity, limited H‑bonding.
   • Lead‑like: moderate MW, moderate lipophilicity, within desired H‑bond and flexibility ranges.
3. Mark each compound as roughly fragment‑like, lead‑like, or outside typical ranges.
4. Use this classification to:
   • Guide screening strategies (e.g., high‑concentration fragment screens vs standard potency assays).
   • Inform design priorities (growing fragments vs optimizing leads).
5. Update thresholds and guidelines as your organization’s strategy evolves.
