Abstract

Novel quinolinone farnesyl transferase inhibitors are provided. These new compounds are useful in the treatment or prevention of synucleinopathies, such as Parkinson'"'"'s Disease, Diffuse Lewy Body Disease, multiple system atrophy, and disorders of brain iron concentration including pantothenate kinase-associated neurodegeneration (e.g., PANK1), or other neurodegenerative/neurological diseases. Provided compounds are also useful in the treatment of proliferative diseases such as cancer, and in the treatment of neurological diseases, such as cognitive impairment, depression, and anxiety.

The treatment including administering to a subject a therapeutically effective amount of an inventive farnesyl transferase inhibitor compound.
