Comment: XL01126 is a VHL-based PROTAC degrader targeting leucine rich repeat kinase 2 (LRRK2). The LRRK2 binding moeity of the compound is the brain-penetrant kinase inhibitor HG-10-102-01. XL01126 is orally bioavailable and retains the ability of the parent kinase inhibitor to cross the blood-brain barrier. LRRK2 is an active therapeutic target for Parkinson's disease, since activating coding mutations in LRRK2 are associated with dominantly inherited Parkinson's disease [1-2,5]. XL01126's development was led by Dundee University's Centre for Targeted Protein Degradation and the Research Institute for Medicines at the University of Lisbon. Initially disclosed in a ChemRxiv preprint [4].
Cereblon-targeting LRRK2 PROTACs have been disclosed previously, but these were found to be inefficient target degraders [3]. |
