Affinity measurements of benzenesulfonamide-bearing compound VD10-13 binding to CA IX by using four different techniques: (a) FTSA, (b) SFA of CO2 hydration enzymatic activity inhibition, (c) ITC and (d) competition assay for cell-expressed CA IX. The insets show raw data curves, while the main panels show processed data dosing curves used for dissociation constant (Kd) calculation. |
