The drug exhibited weak binding affinity to the target protein, resulting in lower efficacy.
O medicamento apresentou afinidade de ligação fraca à proteína alvo, resultando em menor eficácia.
2. A condition where molecular interactions are transient and easily reversible, typically indicating less stable complex formation
Weak binding affinity often necessitates higher drug concentrations to achieve therapeutic effects.
