AlphaFold Protein Structure Prediction Eliminating the X-Ray Crystallography Bottleneck for Each New Drug Target Has Enabled Structure-Based Drug Design at the Scale of All Human Proteins Without the Months of Experimental Structure Determination That Each Target Previously Required.DeepMind's AlphaFold2 database providing 200-plus million protein structure predictions has been integrated into drug discovery workflows at every major pharmaceutical company within 2 years of publication, enabling virtual screening and molecular docking against previously unstructured targets. Structure-based virtual screening using AlphaFold-predicted structures has identified initial hit compounds for EIF4A RNA helicase in oncology, NLRP3 inflammasome in inflammatory disease, and SHH pathway components in paediatric cancer that have entered optimisation programmes. The practical limitation is the static single-state structure prediction that does not capture conformational dynamics and cryptic binding sites revealed by experimental structural biology, making AlphaFold most effective when combined with experimental validation of predicted binding modes.

DNA-Encoded Chemical Library Screening of Hundreds of Millions to Billions of Compounds Through Affinity Selection and NGS Barcode Readout Has Extended Hit Discovery to Chemical Space That Conventional HTS Cannot Access at Affordable Cost.Pfizer, Sanofi, GSK, and Roche have each built internal DEL libraries exceeding 1 billion compounds incubated with protein targets and sequenced to identify binding compounds in 1-2 weeks, compared with months required to screen 1-2 million compounds through traditional HTS robotics. Machine learning analysis of sequencing count data identifies binding pharmacophores guiding synthetic chemistry toward high-affinity lead compounds, and Hitgen, WuXi AppTec, and X-Chem provide external DEL library access at 10-100 billion compound scale. DEL-derived hits entering clinical development from AbbVie, Pfizer, and Roche programmes have established DEL as a validated complement to structure-based and AI-guided drug discovery.

Patient-Derived iPSC Organoid Phenotypic Drug Discovery Models Recapitulating Human Disease More Faithfully Than Rodent Models Are Addressing the Clinical Translation Failure That Target-Centric Rodent Model Drug Discovery Has Generated at 90 Percent Attrition.Pfizer's ibrutinib and Amgen's sotorasib established that targeted covalent inhibitors achieving irreversible enzyme inhibition can generate superior clinical efficacy compared with reversible inhibitors of the same target through sustained complete pathway suppression, providing the pharmacological rationale for systematic covalent druggability screening across the proteome. Frontier Medicines, EuCARES, and Vividion Therapeutics's chemoproteomic screening platforms are systematically identifying cysteine, lysine, and tyrosine residues across thousands of proteins that are selectively reactive with covalent warheads in a target-specific cellular context, enabling rational covalent drug discovery beyond the fortuitous cysteine identification that characterised early KRAS G12C and BTK inhibitor programmes. The extended target residence time from irreversible covalent binding creates pharmacokinetic-pharmacodynamic dissociation where resynthesis of the target protein determines drug duration rather than plasma half-life, enabling once-daily dosing from drugs with short plasma half-lives and reducing the peak concentration toxicity that continuous receptor occupancy from equivalent reversible inhibitors generates.
