Deep Kinetic Characterization: When IC50 Isn’t Enough

Understand why characterizing time-dependent inhibition provides critical insights for lead discovery.

Not all kinase inhibitors are alike. In some cases, the compound’s degree of target inhibition varies with time—known as time-dependent inhibition (TDI).

Endpoint assays that determine inhibitor potency at a single timepoint rely on the assumption that the initial reaction rate is maintained throughout the progress curve. Therefore, these assays do not capture lags at the beginning or saturation at the end of the curve. Instead, a deep kinetic characterization of your compound allows you to fully quantify binding kinetics and structure kinetic relationships so you can capitalize on inhibitor mechanisms of action.

A continuous assay, like our PhosphoSens assay, that measures the catalytic event of phosphorylation in real time enables determination of kinetic parameters that power your drug discovery research.
