  Heteroaromatic-aminomethyl quinolones: Potent and selective iNOS inhibitors

  摘要：

  The overproduction of nitric oxide during the biological response to inflammation by the nitric oxide synthase (NOS) enzymes have been implicated in the pathology of many diseases. By removal of the amide core from uHTS-derived quinolone 4, a new series highly potent heteroaromatic-aminomethyl quinolone iNOS inhibitors 8 were identified. SAR studies led to identification of piperazine 22 and pyrimidine 32, both of which reduced plasma nitrates following oral dosing in a mouse lipopolysaccharide challenge assay. (C) 2011 Elsevier Ltd.

  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.

  There are three isoforms of dimeric nitric oxide synthases (NOS) that convert arginine to citrulline and nitric oxide. Inducible NOS is implicated in numerous inflammatory diseases and, mote recently, in neuropathic pain states. The majority of existing NOS inhibitors are either based on the structure of arginine or are substrate competitive. We describe the identification from an ultra high-throughput screen of a novel series of quinolinone small molecule, nonarginine iNOS dimerization inhibitors. SAR studies on the screening hit, coupled with an in vivo lipopolysaccharide (LPS) challenge assay measuring plasma nitrates and drug levels, rapidly led to the identification of compounds 12 and 42-potent inhibitors of the human and mouse iNOS enzyme that were highly selective over endothelial NOS (eNOS). Following oral dosing, compounds 12 and 42 gave a statistical reduction in pain behaviors in the mouse formalin model, while 12 also statistically reduced neuropathic pain behaviors in the chronic constriction injury (Bennett) model.
