For example, virtual screening can be used as an early stage of the drug discovery pipeline to evaluate the interactions between large datasets of small molecules and a drug target, identifying potential hit candidates. This approach helps in identifying potential hit candidates by predicting how different compounds will bind to the target protein, which will go further in the experimental validation. 177: 578: 522: 682: 470: 758: 732: 708: 630: 604: 496: 420: 394: 368: 340: 550: 801: 31: 295:
