Definitions

  • the present patent application is directed to imidazole biaryl compounds which act as inhibitors of 5-Nitrosoglutathione reductase (GSNOR).
  • GSNOR 5-Nitrosoglutathione reductase
  • the present patent application further provides processes for their preparation, pharmaceutical compositions comprising the compounds, and the use of the compounds or the compositions in the treatment or prevention of various diseases, conditions and/or disorders mediated by GSNOR.
  • GSNO 5-Nitrosoglutathione
  • SNO 5-nitrosothiol
  • NO nitric oxide
  • Increases in bioavailable NO are associated with anti-inflammatory and smooth muscle relaxant effects, especially in organ systems characterized by smooth muscle and endothelial/epithelial layers such as the respiratory, cardiovascular, and gastrointestinal systems (Whalen et al., Cell, 2007, 129, 511-522; Foster et al., Trends Mol. Med., 2009, 15, 391-404; Pacher et al., Physiol. Rev., 2007, 87, 315-424).
  • GSNOR 5-nitrosoglutathione reductase
  • HMGSH hydroxymethylglutathione
  • ADH alcohol dehydrogenase superfamily
  • GSNOR catalyses the oxidation of HMGSH to 5-formylglutathione using a catalytic zinc and NAD+ as a coenzyme.
  • the enzyme also catalyses the NADH-dependent reduction of S- nitrosoglutathione (GSNO) (Kubienova et al., Biochimie, 2013, 95(4), 889-902). It is a primary ADH that is ubiquitously expressed in plant and animals.
  • GSNOR reduces 5-nitrosoglutathione (GSNO) to the unstable intermediate, S- hydroxylaminoglutathione, which then rearranges to form glutathione sulfinamide, or in the presence of GSH, forms oxidized glutathione (GSSG) and hydroxyl amine (Jensen et al., Biochem. J., 1998, 331(2), 659-68; Hedberg et al., Eur. J. Biochem., 2003, 270, 1249-1256; Staab et al., Chem. Biol. Interact., 2009, 178(1-3), 29-35).
  • GSNOR regulates the cellular concentrations of GSNO and plays a central role in regulating the levels of endogenous 5-nitrosothiols and controlling protein S- nitrosylation-based signaling.
  • GSNOR is also involved in regulating NO levels and signaling, pleiotropic effects are observed in GSNOR knockout models.
  • Deleting the GSNOR gene from both yeast and mice increased the cellular levels of GSNO and nitrosylated proteins, and the yeast cells showed increased susceptibility to nitrosative stress (Liu et al., Nature, 2001, 410(6827), 490-494), Null mice show increased levels of 5-nitrosated proteins, increased beta adrenergic receptor numbers in lung and heart (Whalen et al., Cell, 2007, 129(3), 511-522), diminished tachyphylaxis to p2-adrenergic receptor agonists, hypo-responsiveness to methacholine and allergen challenge and reduced infarct size after occlusion of the coronary artery (Que et al., Science, 2005, 308(5728), 1618-1621; Lima et al., Proc.
  • GSNO depletion associates with various diseases including asthma ⁇ Chem. Biol. Interact, 2009, 178(1-3), 29-35).
  • GSNOR expression has been inversely correlated with 5-nitrosothiol (SNO) levels in the alveolar lining fluid in the lung and with responsiveness to methacholine challenge in patients with mild asthma (Que et al., Am. J. Respir. Crit. Care Med., 2009, 180(3), 226-231).
  • SNO and NO concentrations regulate respiratory function by modulating airway tone and pro- and antiinflammatory responses in the respiratory tract (Snyder et al., Am. J. Respir. Crit.
  • GSNO in concentrations present in the airways relaxes airway smooth muscle (Gaston et al., Proc Natl Acad Sci., 1993, 90, 10957-10961), improves airway ciliary motility (Li et al., Am J Respir Cell Mol Biol., 2000, 23, 175— 181), inhibits airway epithelial amiloride-sensitive sodium transport while activating calcium-dependent epithelial chloride transport (Jain et al., Am J Physiol., 1998; 274, 475-484, Kamosinska et al., Am J Physiol., 1997, 272, 1098-1104), promotes neutrophilic apoptosis (Fortenberry et al., Am J Physiol., 1999, 276, L435-L442), and has anti
  • GSNO cystic fibrosis transmembrane regulation protein
  • CFTR cystic fibrosis transmembrane regulation protein
  • AF508 cystic fibrosis transmembrane regulation protein
  • levels of GSNO tend to be low in the cystic fibrosis (CF) airway (Grasemann et al., J Pediatr., 1999, 135, 770-772).
  • aerosolized GSNO is well tolerated by cystic fibrosis patients (Snyder et al., Am. J. Respir. Crit. Care Med., 2002, 165(7), 922-926).
  • GSNO also plays an important role in inflammatory bowel disease (IBD). NO and GSNO maintain normal intestinal physiology via anti-inflammatory actions and maintenance of the intestinal epithelial cell barrier. In IBD, reduced levels of GSNO and NO are evident and may also occur via up-regulation of GSNOR activity (Savidge et al., Gastroenterology, 2007, 132, 1344-1358). In human asthma, there are lowered SNO concentrations in the lungs, likely attributable to up-regulated GSNOR activity (Que et al., Am. J. Respir. Crit. Care Med., 2009, 180, 226-231).
  • mice with genetic deletion of GSNOR exhibit increases in lung SNOs and are protected from airway hyper-responsivity (Que et al., Science, 2005, 308, 1618-1621).
  • GSNOR has been shown to have an important influence on NO containing species, regulation of smooth muscle tone in the airways, and function of adrenergic receptors in lungs and heart (Whalen et al., Cell, 2007, 129, 511-522; Que et al., Am. J. Respir. Crit. Care Med., 2009, 180, 226-231; Liu et al., Cell, 2004, 116, 617-628).
  • GSNOR inhibitors have been demonstrated in animal models of chronic obstructive pulmonary disease (COPD) (Blonder et al., Am. J. Respir. Crit. Care Med., 2011, 22727) and high salt induced hypertension (Chen et al., Appl Physiol, 2013, 114(6), 752-760).
