Computational Drug Discovery
This application area focuses on using computational methods to design, prioritize, and optimize therapeutic candidates—proteins, small molecules, and binders—before they reach the wet lab. It integrates structure prediction, virtual screening, and generative design to explore vast chemical and structural spaces far more quickly than traditional experimental workflows. By predicting protein structures (including hard-to-resolve or intrinsically disordered proteins) and modeling their conformations, these tools enable more rational target selection and structure-based design when experimental data are missing or incomplete. For organizations in biopharma and adjacent sectors, this dramatically compresses early R&D timelines, reduces the number of physical experiments required, and increases the probability of finding viable hits and leads. AI and physics-based models work together to propose and prioritize candidate molecules or miniprotein binders, guide synthesis planning, and improve virtual screening hit rates. The result is faster, cheaper, and more targeted discovery pipelines that expand the druggable target space and de‑risk investment in new therapeutic programs.
The Problem
“Shrink wet-lab cycles with structure-driven virtual screening and generative design”
Organizations face these key challenges:
Wet-lab screening is slow and expensive, forcing small candidate sets and missed opportunities
Limited structural biology bandwidth (cryo-EM/X-ray) delays programs, especially for hard targets
High attrition due to poor early prediction of binding, selectivity, and developability (ADMET, stability)
Siloed data (assay results, structural data, literature) makes target-to-lead decisions inconsistent and hard to audit
Impact When Solved
The Shift
Human Does
- •Select targets based on limited structural/functional evidence; commission or run structure determination
- •Design molecules manually using SAR intuition; triage ideas in meetings
- •Plan syntheses with chemists and CROs; manage queues and rework when routes fail
- •Interpret assay data and decide next compounds across slow iteration loops
Automation
- •Rule-based filtering (Lipinski/PAINS), basic docking on a single structure, and spreadsheet-driven prioritization
- •Simple QSAR models trained on small internal datasets with limited generalization
Human Does
- •Define program constraints (mechanism, ADMET/Tox, selectivity, safety/handling, manufacturing constraints, mission timelines)
- •Review AI-proposed candidate lists and rationales; approve a small set for synthesis and testing
- •Design focused experiments to validate binding/mechanism and feed results back to models (active learning)
AI Handles
- •Predict target structures and conformational ensembles (including hard-to-resolve/disordered regions) for docking and design
- •Run large-scale virtual screening and rank candidates using ML + physics scoring; flag liabilities (reactivity, tox risks, off-targets)
- •Generate novel molecules/miniprotein binders optimized for binding + constraints; propose synthesizable routes and alternatives
- •Continuously learn from assay outcomes to refine prioritization and suggest next-round compounds (closed-loop optimization)

AlphaFold2-Derived Target Structures + Managed Docking Batch for Hit Triage
Generate target structures using AlphaFold2 (or consume public AlphaFold DB where applicable), prepare binding-site hypotheses, and run managed/turnkey virtual screening (commercial docking suites or cloud-hosted pipelines) on pre-enumerated libraries. Results are used to rank a tractable shortlist for synthesis or procurement, with basic physicochemical and rule-based developability filters.

PostEra AI-Driven Drug Design Platform
This is like having a super-smart coding assistant for drug discovery: chemists describe what kind of medicine they want in code or constraints, and the AI proposes new molecules and lab routes to make them—far faster than humans could by hand.
AlphaFold for AI-Driven Drug Discovery
This is like having a super-smart microscope in the cloud that can predict how every protein in the body is shaped, letting you design drugs on a computer instead of only through slow, expensive lab trial-and-error.
Hybrid AI/physics pipeline for miniprotein binder prioritization
This is like a super-smart screening funnel for drug-like mini-proteins. Instead of testing millions of molecules in the lab, it uses a combination of AI predictions and physics-based simulations to quickly sort through candidates and highlight the handful most likely to stick to a disease target.
Leveraging AlphaFold2 Structural Space Exploration for Generating Drug Target Structures in Structure-Based Virtual Screening
This approach uses AlphaFold2 (an AI that predicts 3D protein shapes) not just to get one structure per protein, but to explore many plausible shapes of a drug target. These AI‑generated shapes are then used as ‘locks’ in large-scale virtual screening to find small‑molecule ‘keys’ (drug candidates) that fit, even when proteins flex or change shape.
AI-Driven Structural Prediction for the Dark Proteome
This is like using a super-smart microscope that doesn’t look at proteins directly, but instead uses physics and patterns learned from millions of known proteins to "guess" the shapes of mysterious, previously unmeasurable proteins in our bodies.
