A compound’s chemical and metabolic profiling directly impact systemic exposure, therapeutic efficacy, and safety. Instability can lead to rapid clearance, shortened half-life, and compromised in vivo performance.

At Sygnature Discovery, we provide comprehensive in vitro chemical and metabolic stability assessments to support compound optimization and predict in vivo pharmacokinetics. Our assays evaluate parent depletion kinetics and intrinsic clearance (CLint) across species, enabling accurate IVIVE and guiding structure refinement. Importantly, our CLint data show strong correlation with in vivo CLint of marketed compounds, supporting successful scaling and enhancing translational confidence.


We offer targeted evaluations of:

  • Chemical Stability: Identifying pH-dependent degradation in biorelevant media
  • Plasma & Blood Stability: Assessing hydrolytic liability and ex vivo degradation risks
  • Microsomal & Hepatocyte Stability: Determining metabolic clearance
  • Hepatic Uptake: Quantifying transporter-mediated clearance to resolve IVIVE disconnects and improve prediction accuracy.
Laboratory setup with automated systems and analytical instruments used for chemical and metabolic stability assays, supporting predictive pharmacokinetic insights.

Dedicated DMPK for Degraders – a flexible approach for flexible molecules
Bifunctional degraders bind and degrade proteins via ubiquitin ligase, despite breaking bRo5 rules. Translating in vitro DMPK data to in vivo performance remains a challenge. At Sygnature Discovery, we provide tailored assays and expertise to support projects involving these compounds. Read more in the poster.
