PDB Ligand
Compound class: Synthetic organic
Comment: Indisulam is an anticancer sulfonamide that is in clinical development. This compound belongs to the family of carbonic anhydrase inhibitors. It also behaves as a type of molecular glue that targets certain proteins for ubiquitination and proteasomal degradation [1,3], by bringing them into the proximity the CUL4-DDB1-DDA1-DCAF15 E3 ubiquitin ligase complex.
