Decipher Your Compound’s Mechanism of Action
Investigate binding kinetics of your selected inhibitor(s)
Our service utilizes structure-activity relationship (SAR) analysis with IC50 potency assays to elucidate the mechanism of action (MoA) of your shortlisted kinase inhibitors. This approach systematically evaluates the impact of structural modifications on inhibitor potency (IC50) against:

- Wild-type target kinase: The unmodified form of the target kinase
- Kinase variants harboring mutations: These variants contain targeted modifications in key kinase domains
By meticulously comparing IC50 values across these variants, you gain invaluable insights into the critical binding interactions between the inhibitor and the kinase. We help identify three key interaction types:
- Covalent inhibitor: Forms a direct chemical bond with the kinase.
- ATP-competitive: Competes with ATP for binding to the ATP-binding pocket.
- Substrate-competitive: Competes with the substrate for binding to the substrate-binding pocket.
This refined approach not only confirms your initial kinase activity profiling findings but also provides a deeper mechanistic understanding, paving the way for targeted optimization strategies.
Kinase Selectivity Profiling
Explore selectivity and off-target effects of your compounds across the human kinome
We offer the industry’s largest collection of the human kinome with more than 700+ kinases. Our flexible approach allows you to preselect a subfamily of kinases or the entire human kinome.
Benefits of Kinase Selectivity Profiling:
- Early Detection of Off-Target Effects: Proactive identification of drug selectivity and potential liabilities minimizes risk and saves resources during development.
- Unveiling New Kinase Opportunities: This analysis can reveal unexpected sensitivities towards other kinases within your target pathway, potentially leading to the discovery of novel therapeutic targets.
