Product Description
TMX-4113 is a degrader of phosphodiesterase 6D (PDE6D) and casein kinase 1α (CK1α). TMX-4113 may be used in cancer-related research.
TMX-4113 is a small-molecule heterobifunctional degrader specifically designed to target and induce the proteasomal degradation of phosphodiesterase 6D (PDE6D) and casein kinase 1alpha (CK1alpha). It functions as a chemical probe for investigating the oncogenic roles of these proteins in cancer biology. The compound features a cereblon E3 ligase-recruiting moiety linked to a target-binding ligand, which brings the E3 ligase into proximity with PDE6D and CK1alpha, leading to their ubiquitination and subsequent degradation. This mechanism allows for the permanent removal of the target proteins rather than transient inhibition, providing a powerful tool for studying the functional consequences of PDE6D and CK1alpha loss in cellular signaling pathways. TMX-4113 is strictly a research-grade compound and is not approved for any therapeutic use.
Biological Activity I Assay Protocols (From Reference)
Targets
PDE6D CK1α
PDE6D (phosphodiesterase 6D) and CK1alpha (casein kinase 1alpha).
ln Vitro
In MOLT4 cells, TMX-4113 (compound 21; 1 μM; 4 h) exhibits a strong preference for PDE6D and CK1α degradation[1]. In MOLT4 cells, TMX-4113 (0 nM, 40 nM, 200 nM, 1µM; 4h) causes PDE6D degradation[1]. At a dosage of 40 nM, TMX-4113 (0 nM, 40 nM, 200 nM, 1µM; 4h) destroys more than 50% of CK1α in MM.1S cells[1].
In MOLT4 cells, TMX-4113 (compound 21; 1 microM; 4 h) exhibits a strong preference for degrading PDE6D and CK1alpha. At a concentration of 40 nM, it destroys more than 50% of CK1alpha in MM.1S cells. In MOLT4 cells, TMX-4113 (0-1 uM; 4h) induces PDE6D degradation in a dose-dependent manner.
ln Vivo
No specific in vivo data has been identified for TMX-4113 in the available literature. However, as a targeted protein degrader, it is anticipated to be utilized in xenograft mouse models to evaluate its efficacy in degrading PDE6D and CK1alpha in a tumor microenvironment and to assess its potential anti-tumor activity in future cancer research studies.
Enzyme Assay
Western blot analysis is used to assess protein degradation. Cell Types: MOLT4 cells. Tested Concentrations: 1 microM. Incubation Duration: 4 h. Experimental Results: demonstrated a high degradation preference for PDE6D and CK1alpha. For dose-response, cells are treated with 0 nM, 40 nM, 200 nM, and 1 uM for 4 h.

Additional Infomation
TMX-4113 (CAS#: 2766385-92-4) is a dual-target protein degrader. It functions by recruiting the ubiquitin-proteasome system to degrade its target proteins PDE6D and CK1alpha. This mechanism of action is distinct from traditional enzyme inhibition, as it leads to the permanent removal of the target protein rather than just blocking its activity. It is a valuable chemical probe for studying the biological functions of PDE6D and CK1alpha in cancer signaling pathways. Purity: ≥98%.
