WebThe Kinact/Ki values and IC50 values were compared for the purpose of assessing their irreversible BTK inhibitor,tirabrutinib, for selectivity relative to other irreversible BTK inhibitors. The investigators reported that selectivity assessment using IC50 values tended to exaggerate selectivity relative to the selectivity measured by Kinact/Ki8), … Webinact (Fig. 1B) is also determined by numerical in-tegration approach. Thus, we separate the overall inhibitory effect into two contributing components: the strength of non-covalent binding and the chemical reactivity of the initial enzyme–inhibitor complex.
