Acts 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).

Programmed Cell Death Poster
There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
Targeted Protein Degradation PosterNew
Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed.
