Inactivation Kinetics

Our highly robust kinetic platform delivers all key inactivation (kinact, kinact/KI, T1/2∞) and affinity (KI) parameters for irreversible binders.

De-risking irreversible drug discovery

Irreversible inhibition is time dependent and intrinsically related to both the affinity (KI) and reactivity (kinact) of the covalent inhibitor. These data are more relevant to the optimization of irreversible inhibitors than IC50 values, enabling drug hunters to properly identify irreversible compounds, rank structure-activity relationships (SAR), interpret selectivity and define in vivo target occupancy.

Applications

  • Easier decision-making: An ideal hit-to-lead and lead optimization tool to facilitate parallel improvement of both compound binding and covalent bond formation.
  • Selectivity profiling for irreversible drugs: Evaluating inactivation efficiency (kinact/KI) accurately defines the time-dependent effects of covalent binding and enables the safety profile of irreversible drugs to be more rigorously assessed.
  • Build better models: PK/PD models that integrate kinetics better predict target engagement, drug dose and treatment schedule.

List of targets ready to use

Our expertise extends beyond kinases to GPCR and other target types.

Search our database to discover whether your target is:
  • May be possible: We have a strong track record of achievement where others fail! Contact us to find out more.
  • Clear line of sight: Establishment requires finalization / validation, which typically takes 2-4 weeks to complete.
  • Good to go: Data within 2 weeks of compound receipt.

* Full length and partial length forms are available.
