Dataset Summary
TitleAddressing Enzymatic-Independent Tumor-Promoting Function of NAMPT via two PROTAC-Mediated Degradation
DescriptionThe rate-limiting enzyme of salvage pathway for NAD+ synthesis, NAMPT, is aberrantly overexpressed in a variety of tumor cells and is a poor prognosis factor for patient survival. NAMPT plays a major role in tumor cell proliferation, acting concurrently as an NAD+ synthase and unexpectedly, an extracellular ligand for several tumor-promoting signaling pathways. While previous efforts to modulate NAMPT activity were limited to enzymatic inhibitors with low success in clinical studies, protein degradation offers a possibility to simultaneously disrupt NAMPT’s enzyme activity and ligand capabilities. Here, we report the development of two highly selective NAMPT-targeted proteolysis-targeting chimeras (PROTACs), which promoted rapid and potent NAMPT degradation in a cereblon-dependent manner in multiple tumor cell lines. Notably, both PROTAC degraders outperform a clinical candidate, FK866, in killing effect on hematological tumor cells. These results emphasize the importance and feasibility of applying PROTACs a
