Carbonic Anhydrase and Bone Remodeling: Sulfonamide Inhibition of Bone Resorption in Organ Culture

Abstract
Five sulfonamide inhibitors of carbonic anhydrase inhibited parathyroid hormone-induced resorption of bone in organ culture. The relative activities of the sulfonamides as resorption inhibitors were such as to suggest the presence of a functional carbonic anhydrase system in bone linked to the mechanism of bone resorption.
