enzymes. KI values of these compounds against hCA I and hCA II were in the range of 2.14–16.32 μM, and 0.34–2.52 μM, respectively. Isozyme hCA IV was inhibited with KI-s in the range of 0.435–5.726 μM, while hCA VI with KI-s of 1.92–12.84 μM bCA III was inhibited with KI-s in the range of 2.13–17.83 μM. The structurally related compounds, 1,2-dimethoxybenzene, catechol and indole were also tested in order
