XL01126, a potent degrader of LRRK2, exhibits DC50 values of 14 nM (G2019S LRRK2) and 32 nM (WT LRRK2), respectively. It has the ability to cross the blood-brain barrier, making it a viable degrader probe for Parkinson’s disease research. This compound is instrumental in exploring the non-catalytic and scaffolding functions of LRRK2 [1].
