Dual inhibitors of bacterial gyrB and parE based on a 5-(2-pyrimidinyl)-imidazo[1,2-a]pyridine template exhibited MICs (mu g/mL) of 0.06-64 (Sau), 0.25-64 (MRSA), 0.06-64 (Spy), 0.06-64 (Spn), and 0.03-64 (FQR Spn). Selected examples were efficacious in mouse sepsis and lung infection models at <50 mg/kg (PO dosing). (C) 2009 Elsevier Ltd. All rights reserved.
