S9742 Indisulam (E7070) Indisulam (E7070), a sulfonamide anticancer agent, is a potent carbonic anhydrase (CA) inhibitor that inhibits cytosolic isozymes I and II, and transmembrane, tumor-associated isozyme IX. Indisulam suppresses the expression of cyclin E and phosphorylation of CDK2, both of which are essential for the G1 to S transition.
