2-Amino-6-sulfamoylbenzothiazole (SMABT) and its proton transfer compound (HSMABT)+(HDPC)− (1) with 2,6-pyridinedicarboxylic acid (H2DPC), and their Cu(II) complexes (2 of SMABT, 3 and 4 of 1) have been prepared and characterized by spectroscopic techniques. Additionally, single crystal X-ray diffraction techniques were applied to all complexes. All compounds, including acetazolamide (AAZ) as the control compound, were also evaluated for their in vitro inhibition effects on human hCA I and hCA II for their hydratase and esterase activities. The synthesized complexes have remarkable inhibitory effects on hCA I and hCA II isoenzymes. The inhibition potentials of the proton transfer salt (1) and the metal complexes (2–4) are comparable with AAZ. Esterase Ki values of the compounds (1–4) are in the range of 0.089 ± 0.008 μM-0.149 ± 0.017 μM for hCA I and 0.046 ± 0.008 μM-0.085 ± 0.019 μM for hCA II. Inhibition data have been analyzed by using a one-way analysis of variance for multiple comparisons (p < 0.0001).
