Chemical Name: N1-(3-Chloro-1H-indol-7-yl)-1,4-benzenedisulfonamide
Biological ActivityActs as a molecular glue to induce proteosomal degradation of mRNA splicing factor RBM39 (also designated CAPERα, HCC1, FSAP59, and RNPC2), via binding to DCAF15. Acts as a pre-mRNA splicing modulator (SPLAMs; splicing inhibitor sulfonamides), causes aberrant pre-mRNA splicing. Suppresses proliferation of cancer cell lines. Reduces viability of HCT-116 cells (IC50 = 0.56 μM). Induces cell cycle arrest in the G1 phase in cancer cell lines. Also a high affinity carbonic anhydrase isozyme XII (hCA XII) inhibitor (Ki = 3.0-5.7 nM).
