Optimization Of Orally Bioavailable Inhibitors Of Defective In Cullin Neddylation 1 (Dcn-1), Leah Kovalic

Theses and Dissertations--Pharmacy

Ubiquitin (UB) and ubiquitin-like protein (UBL) pathways have emerged as important targets for oncology drug discovery based on the success of proteasome inhibitors (bortezomib or carfilzomib), E3 inhibitors, and the NEDD8 E1 inhibitor pevonedistat (MLN42924). Chemical inhibitors have also proven to be useful probes for identifying and dissecting multifactor UB and UBL regulatory networks. Toward this end, we have pursued approaches to target NEDD8 ligation to Cullins, through developing small molecule inhibitors of DCN1 (defective in Cullin Neddylation 1). DCN1 was discovered as a potentiating RBX1-dependent NEDD8-ligation, through recognizing the acetylated N-terminal methionine of the NEDD8 E2s UBE2M and UBE2F. …
