Flexible Discovery Models
Tailored to Your Program, Built for Real Progress
Drug discovery rarely follows a straight line. At X-Chem, we understand that each program’s path is unique, with its own goals, challenges, and timelines. That’s why we offer flexible, milestone-driven discovery models specifically designed to deliver the right insights at the right stage.
Our team meets you exactly where you are, whether you’re just starting to evaluate target tractability, ready to develop high-potential leads, or preparing for IND-enabling studies.
We adapt our approach to:
- Validate and prioritize new targets
- Generate deep SAR and refine lead series
- Optimize compounds toward candidate nomination

HitBuilder
Fast, Focused Validation of Your Target
HitBuilder delivers a clear path forward for early-stage programs or novel targets. You’ll rapidly assess target tractability, generate high-quality, computationally guided DEL-derived hits, and receive synthesized compounds with supporting SAR analysis—while maintaining the flexibility to proceed on your terms.
Key features:
- Rapid, low-risk target validation
- Pre-screen QC and condition optimization, DEL-based tractability, project-tailored DEL screening
- Exclusive and non-exclusive models available
- HitMiner predictive modeling for fast initial validation from purchasable catalogs
- Computational analysis, delivering rich protein structure-function insights via ligand and structure-based methods, which include large-scale pharacophore development based on extensive positive and negative data from DEL
- Well-characterized hits, synthesized off-DNA
- Ideal for novel or traditionally undruggable targets
LeadBuilder
Accelerate from Validated Hits to Prioritized Leads
LeadBuilder moves validated hits forward, delivering refined and prioritized analogs with clearly defined structure–activity relationships. Integrating advanced computational modeling, and medicinal chemistry expertise, LeadBuilder positions your program for confident progression.
Key features:

- Comprehensive analog synthesis
- Integrated DEL: inclusive of rich SAR structure-function mapping and predictive modeling
- Clear progression and prioritization toward leads with simultaneous multi-parameter optimization
CandidateBuilder
Your Comprehensive Path to Development-Ready Candidates
CandidateBuilder provides a seamless, end-to-end pathway from generating validated hits to delivering nomination-ready development candidates. This comprehensive engagement covers everything from target assessment through initial DEL-based SAR mapping, multi-series hit finding, simultaneous multiparameter optimization, ADME/DMPK refinement and IND-enabling data packages.
Key features:
- Complete integration of HitBuilder and LeadBuilder offerings
- Extensive lead optimization and iterative analog design (100+ compounds)
- In vitro and computational multiparameter optimization
- Full ADME, DMPK profiling, and liability mitigation
- IND-enabling data packages and candidate nomination support
