Abstract

Fas-associated factor 1 (FAF1), a death–promoting protein, plays disease-promoting roles in neurodegenerative diseases, especially the Parkinson’s disease (PD). PD is the second most common neurodegenerative disease characterized by the selective loss of dopaminergic neurons. FAF1 expression was increased in the PD patients’ brains, leading us to explore FAF1’s role in the pathogenesis of PD. We identified FAF1 as a substrate of Parkin and found that FAF1 promotes α-synuclein accumulation, demonstrating the presence of Parkin–FAF1–α-synuclein signaling axis. FAF1 drove dopaminergic neuronal death by programmed necrosis as well as apoptosis upon oxidative stress. Such characteristic portrayed FAF1 as an advantageous drug target over proteins driving single type of cell death. Subsequently, we screened FAF1 inhibitory compounds and developed a compound targeting FAF1 (CTF), a first-in-class small molecule, and performed pre-clinical study. CTF demonstrated excellent efficacies in cell and in vivo models. At present, the molecule completed phase I clinical trial.
