Leucine-rich repeat kinase 2 (LRRK2) has received considerable attention since the discovery of LRRK2 mutations in families with dominantly inherited Parkinson's disease (PD) in 2004. The missense mutation G2019S is the most common LRRK2 mutation and has been identified in both familial and sporadic PD cases. The G2019S mutation enhances kinase activity suggesting that LRRK2 could be an attractive therapeutic target for PD and small-molecule ATP-competitive LRRK2 kinase inhibitors are one way to investigate this possibility.


Currently, LRRK2 kinase inhibitors are being actively pursued by industry and academia. Herein, patents detailing the discovery of LRRK2 kinase inhibitors from 2006 through 2011 and the corresponding publications from 2006 through July of 2012 are summarized.


Wild-type and mutant forms of LRRK2 are currently being actively pursued as therapeutic targets for the potential treatment of PD. The increasing number of patent applications being filed for inhibitors of LRRK2 is a testament to this activity. Numerous distinct chemo-types have been reported as LRRK2 inhibitors with some demonstrating exceptional potency and selectivity for LRRK2 relative to other kinases. These compounds are being used as pharmacological 'tools' to elucidate the physiological and pathophysiological function of LRRK2 and it appears likely that some will be investigated for their potential therapeutic effects for the treatment of PD.
