PROTAC mHTT Degrader-1 is a blood-brain barrier-penetrant mutant huntingtin (mHTT) PROTAC degrader. PROTAC mHTT Degrader-1 specifically recognizes pathogenic mHTT aggregates and recruits Cereblon (CRBN), thereby inducing ubiquitination and proteasomal degradation of mHTT. PROTAC mHTT Degrader-1 alleviates mHTT-induced cytotoxicity and neuroinflammation. In the R6/2 Huntington's disease mouse model, PROTAC mHTT Degrader-1 reduces cerebral protein aggregation levels and improves body weight, motor coordination and survival rate of animals. PROTAC mHTT Degrader-1 can be used for research on PROTAC therapies for Huntington's disease and other neurodegenerative diseases.
