Protein degraders are emerging as potent therapeutic tools to address neurological disorders and many complex diseases. It offered several key advantages, including the doses, drug resistance, and side effects over traditional occupancy-based inhibitors. Translation of chemical degraders into a clinical therapy for neurodegenerative disorders has a well-documented knowledge and resource gap. Researchers strive to develop clinical candidates employing chemical degraders' technologies, including hydrophobic tagging, molecular glues, proteolysis targeting chimeras (PROTACs), specific and nongenetic Inhibitor of Apoptosis Protein (IAP)-dependent protein erasers (SNIPERs), autophagy targeted chimeras, and autophagosome-tethered compounds for targeted degradation of pathological markers in neurodegenerative disease. Herein, we examined the present state of chemical-mediated targeted protein degradation in the quest for medications to treat neurodegenerative diseases. We further identified targeted degraders under clinical development for neurodegenerative diseases summarizing pertinent discoveries guiding the future of degradation therapeutics. We also addressed the necessary pharmacological interventions needed to achieve unprecedented therapeutic efficacy and its associated challenges.
