    • 50)/#HA (HA = Number of heavy atoms in lead), where greater Ligand Efficiency (when applied in context with other filters i.e. toxicological and pharmacokinetic) is preferred in lead selection (LE > 0.3 is optimal). Thus, during development the chemist has ample room to optimize potency and pharmacokinetic profiles by increasing molecular weight and lipophilicity. Previous to this quantification, non-empirical judgement calls of the medicinal chemist were employed to rank lead starting points and were often simply potency driven.

Simply put, very low molecular weight weak binders are often highly efficient ligands, giving the medicinal chemist ample room to dial in desired potency and ADME/PK properties
