A model result is a research hypothesis or prioritization signal, not evidence of clinical safety or efficacy.
AlphaFold predicts protein structures, while AlphaFold 3 extends structure prediction to biomolecular complexes involving proteins, nucleic acids, small molecules and other components. MoleculeNet describes machine-learning tasks over molecular representations including graphs and SMILES. Deep Docking illustrates one virtual-screening approach that uses predictions to reduce how many compounds require expensive docking calculations. DeepTox and later molecular-generation studies address toxicity prediction and candidate generation; these methods do not establish a compound’s safety, efficacy or clinical success. FDA describes preclinical testing and an IND process before clinical studies in people.
Using AlphaFold to predict protein structures, as reported in its paper and resource database.
Using AlphaFold 3 to predict structures and interactions among proteins, nucleic acids, small molecules and other biomolecules.
Representing molecules as graphs or SMILES strings in molecular-learning benchmarks.
Using virtual screening to prioritize compounds for experimental testing, with predictions treated as uncertain.
Evaluate screening and generation methods on prospective, target-relevant data and report experimental confirmation rates. Follow regulatory requirements for preclinical and human research; remove candidates only after evidence appropriate to the task, rather than treating model scores as final decisions.

AlphaFold menggunakan pembelajaran mendalam untuk meramalkan struktur 3D protein pada skala, memberikan penyelidik rangka tindakan struktur yang sebelum ini mengambil masa bertahun-tahun percubaan.
Molekul secara semula jadi adalah graf (atom = nod, ikatan = tepi) yang diproses oleh rangkaian saraf graf, atau dikodkan sebagai rentetan SMILES untuk model jujukan.
Penapisan maya menggunakan model untuk menjaringkan perpustakaan molekul yang besar dalam silico, jadi hanya calon teratas dibuat dan diuji dalam makmal.
Computational ADME/toxicity predictions can prioritize compounds for follow-up; they are model outputs and do not establish safety or replace experimental testing.
Model generatif seperti VAE dan model resapan mencontohi struktur baharu daripada ruang kimia yang dipelajari, mengoptimumkan untuk sifat yang diingini.
