  Three isoforms of nitric oxide synthase (NOS), dimeric enzymes that catalyze the formation of nitric oxide (NO) from arginine, have been identified. Inappropriate or excessive NO produced by iNOS and/or nNOS is associated with inflammatory and neuropathic pain. Previously, we described the identification of a series of amide-quinolinone iNOS dimerization inhibitors that although potent, suffered from high clearance and limited exposure in vivo. By conformationally restricting the amide of this progenitor series, we describe the identification of a novel series of benzimidazole-quinolinone dual iNOS/nNOS inhibitors with low clearance and sustained exposure in vivo. Compounds were triaged utilizing an LPS challenge assay coupled with mouse and rhesus pharmacokinetics and led to the identification of 4,7-imidazopyrazine 42 as the lead compound. 42 (KD7332) (J. Med. Chem. 2009, 52, 3047-3062) was confirmed as an iNOS dimerization inhibitor and was efficacious in the mouse formalin model of nociception and Chung model of neuropathic pain, without showing tolerance after repeat dosing. Further 42 did not affect motor coordination up to doses or 1000 mg/kg, demonstrating a wide therapeutic margin.
