In Vitro Benzthiazide (0.4, 2, 10 μM) suppresses proliferation of cancer cell under hypoxic conditions in a dose-dependent manner . Benzthiazide is an inhibitor of carbonic anhydrase 9 (CA9), with Kis of 8.0, 8.8 and 10 nM for CA9, CA2 and CA1, respectively[2].
In Vivo Benzthiazide (1, 1.5 mg/100 g BW) causes a marked decrease in urinary calcium excretion and the dissociation of calcium and sodium excretion in hyperprolactinemic rats[1].
