Small molecules targeting the NEDD8·NAE protein-protein interaction.

ABSTRACT: Ubiquitination is a major controller of protein homeostasis in cells. Some ubiquitination pathways are modulated by a NEDDylation cascade, that also features E1 - 3 enzymes. The E1 enzyme in the NEDDylation cascade involves a protein-protein interaction (PPI) between NEDD8 (similar to ubiquitin) and NAE (NEDD8 Activating Enzyme). A small molecule inhibitor of the ATP binding site in NAE is in clinical trials. We hypothesized a similar effect could be induced by disrupting the NEDD8·NAE PPI, though, to the best of our knowledge, no small molecules have been reported to disrupt this to date. In the research described here, Exploring Key Orientations (EKO) was used to evaluate several chemotype designs for their potential to disrupt NEDD8·NAE; specifically, for their biases towards orientatio
