What is Indisulam?
Definition
ChEBI: Indisulam is a chloroindole that is 3-chloro-1H-indole substituted by a [(4-sulfamoylphenyl)sulfonyl]nitrilo group at position 7. It is a carbonic anhydrase inhibitor and a potential anti-cancer agent currently in clinical development. It has a role as an EC 4.2.1.1 (carbonic anhydrase) inhibitor and an antineoplastic agent. It is a chloroindole, a sulfonamide and an organochlorine compound.
Biochem/physiol Actions
Indisulam is a carbonic anhydrase inibitor and Antitumor CDK inhibitor. Indisulam targets the G1 phase of the cell cycle by depleting cyclin E. inducing p53 and p21, and inhibiting CDK2, causing a blockade in the G1/S transition.
