JNJ-Q2 is a broad-spectrum fluoroquinolone antibacterial drug being developed for the treatment of acute bacterial skin and skin-structure infections and community-acquired pneumonia. Specifically, JNJ-Q2 is being actively studied for treatment of methicillin-resistant Staphylococcus aureus (MRSA) infections.^[2]^[3]

Furiex Pharmaceuticals has licensed JNJ-Q2 from Janssen Pharmaceutica, a unit of Johnson & Johnson, which discovered JNJ-Q2. Furiex is responsible for its development and commercialization. Both oral and intravenous formulations are being developed.^[4]
