Abstract

In vitro inhibition of adenosine triphosphatase and carbonic anhydrase by several radiographic contrast media and other compounds was measured. The concentrations required for 50% inhibition were, in general, similar to those obtained for other enzymes. The effect of methylglucamine could not be determined for either enzyme because of interference with the assays.
