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.

How to use

In Vitro:

Following treatment with E7070, the cell cycle progression of P388 murine leukaemia cells is disturbed in the G1 phase. The cell-killing effect on human colon cancer HCT116 cells is found to be time-dependent. In the panel of 42 human tumour cell lines, E7070 shows an antitumour spectrum that is distinct from those of other anticancer drugs used in clinic.

In Vivo:

Animal tests using human tumour xenograft models demonstrates that E7070 can cause not only tumour growth suppression, but also tumour regression in three of five colorectal and two of two lung cancers. In the HCT116 xenograft model, E7070 is shown to be superior to 5-FU, MMC and CPT-11 (irinotecan). Furthermore, complete regression of advanced LX-1 tumours is observed in 80% of E7070-treated mice.
