WebThe value Ki is the dissociation constant describing the binding affinity between the inhibitor and the enzyme, while IC50 is the concentration of inhibitor required to reduce the enzymatic activity to half of the uninhibited value. …. Therefore, IC50 is dependent on the enzyme concentration, and is always larger than Ki. WebJul 8, 2024 · The antiviral activities of two of the novel aldehyde inhibitors were comparable to their enzymatic IC50 values, indicating that further optimizing this class for on-enzyme efficacy may predict ...

WebThe Inhibitory Constant (Ki) and its Use in Understanding Drug Interactions. The inhibitory constant (Ki) and the IC50 of a drug that is known to cause inhibition of a cytochrome P450 (CYP) enzyme have to do with the concentration needed to reduce the activity of that enzyme by half. More specifically the Ki is reflective of the binding ... WebA major strategy used in drug design is the inhibition of enzyme activity.
