Quality-Driven Approach: Designing Success Into
Your Compounds

analysis design synthesis testing process

When you partner with X-Chem, expect a relentless focus on quality and efficiency. We consider key anti-targets, selectivity criteria and the IP landscape to develop screening cascades that maximize speed, efficiency and translational validity. Our team designs your synthetic targets based on strong hypotheses, incorporating physical properties and druggability, rather than potency alone.  

How we optimize your hit → lead → candidate journey: 

  • Prioritizing high passive permeability and solubility 
  • Minimizing transporter interactions and metabolism issues 
  • Assessing potential genotox issues, reactive metabolites and selectivity relative to hERG, CYPs and relevant anti-targets 
  • Driving potency optimization based on therapeutically relevant pharmacological parameters — not just EC50 or IC50 
  • Maximizing the free drug concentration and duration at the site of action, aligning with target-specific PK/PD strategies
