Numerous LRRK2-selective type I kinase inhibitors have been developed, and some have entered clinical trials. Here, to our knowledge, we present the first type II kinase inhibitors that target LRRK2. Targeting the inactive conformation of LRRK2 is functionally distinct from targeting the active-like conformation using type I inhibitors. We designed these inhibitors with a combinatorial chemistry approach fusing selective LRRK2 type I and promiscuous type II inhibitors using iterative cycles of synthesis supported by structural biology and activity testing. Our lead compounds are selective and potent toward both LRRK2 and LRRK1, a close relative of LRRK2. Through cellular assays, cryo-electron microscopy structural analysis, and in vitro motility assays, we show that our inhibitors stabilize the open, inactive LRRK2 kinase conformation. These new conformation-specific compounds will be invaluable as tools to study LRRK2's function and regulation and expand the potential therapeutic options for PD. |
