Accelerate drug discovery with precision and insight
Unlock the full potential of in silico drug discovery with Enamine’s advanced Computer-Aided Drug Design (CADD) services.
By partnering with us, you gain access to custom-tailored modeling workflows that integrate state-of-the-art molecular modeling, AI-powered screening, and medicinal chemistry expertise — all focused on maximizing your success rate in early-stage drug discovery.
Our team will support you through every step — from target identification and structure prediction, to hit identification, lead optimization, and beyond. We combine tools such as structure-based and ligand-based virtual screening, molecular docking, molecular dynamics, and free energy perturbation (FEP) to help you prioritize only the most promising candidates for synthesis and biological testing.
You don’t just get access to computational tools — you get a results-oriented strategy built around binding affinity prediction, ADMET profiling, and real-time decision-making, designed to reduce cost and timeline in your pipeline.
By collaborating with Enamine’s CADD department, you benefit from:- Deeper insight into target behavior and binding pocket dynamics
- Rapid identification and ranking of hits from Enamine REAL and screening libraries
- Integration of AI, ML, and cheminformatics to explore vast chemical space
- Seamless transition from virtual screening to synthesis and biological validation
Whether you're working with a challenging protein, RNA structure, or novel chemical series, our computational chemistry expertise helps you design, predict, and optimize with confidence.
We use a balanced approach employing different methods complementing each other

Every Project Starts with an Evaluation Phase
Before launching full-scale modeling, we always begin with a project evaluation phase — a concise analytical step designed to:
- define a scientifically legit strategy for virtual screening or lead optimization
- assess the availability and suitability of structural data (targets, ligands, etc.)
- recommend the most effective approach and scope tailored to your goals and constraints
- identify potential risks or challenges in early-stage drug discovery campaign
