| Hazard Information | Back Directory | [Uses]
The sodium salt of Tasisulam has potential antineoplastic activity. Selectively toxic towards tumor cells, tasisulam appears to induce tumor cell apoptosis by a mitochondrial-targeted mechanism involving the loss of mitochondrial membrane potential and induction of reactive oxygen species (ROS). | [Biological Activity]
Tasisulam (LY573636) is a SPLAM (SPLicing inhibitor sulfonAMide) th at bridges RNA binding motif protein 39 (RBM39; CAPERαHCC1) and DCAF15 for interactionthereby promoting (CUL4-DDB1-DDA1-DCAF15) E3 ubiquitin ligase complex-mediated RBM39 ubiquitination and subsequent proteasomal degradation. Tasisulam exerts selective toxicity in parental HCT116 cancer cultures (IC50 = 6.5 μM)but not those harboring non-CUL4-DCAF15-associating RBM39 G268V mutant even at a high concentration of 50 μM. |
