Definitions
- PROTEASE ACTIVATED RECEPTOR 2 (PAR2) ANTAGONISTS
- This invention relates to compounds that are PAR2 receptor antagonists, to compositions containing them, to processes for their preparation, and to their use in medicine, in particular for the treatment of conditions which respond to antagonism of the PAR2 receptor, such as inflammation, intestinal inflammation, inflammatory skin diseases including psoriasis and itch, fibrosis, arthritis, pain, cancer and pancreatitis.
- Protease activated receptors are a family of seven transmembrane domain G-protein-coupled receptors that are activated by cleavage of their extracellular N-terminal domain by proteolytic enzymes. The newly exposed N- terminal sequence acts as a tethered ligand that binds to the extracellular face of the receptor and activates it.
- PARs Four PARs have been described that are selectively cleaved by different enzymes; PARI , PAR3 and PAR4 are cleaved by thrombin, PAR2 and PAR4 predominantly by trypsin and tryptase and PAR4 also cleaved by cathepsin G.
- the Gl tract and pancreas are particularly exposed to a large array of proteases which can activate PAR2 receptors. Trypsin is released into the lumen of the pancreatic duct and the upper Gl tract, for physiological digestive purposes. Other proteases abundant in the Gl tract include those derived from enteric bacteria and those generated during disease processes. On mucosal surfaces, a balance between proteolytic activity and the presence of protease inhibitors such as pancreatic secretory trypsin inhibitor (PSTI) is constantly present.
- PSTI pancreatic secretory trypsin inhibitor
- PAR2 receptors are expressed throughout the Gl tract specifically on mast cells, smooth muscle cells, myenteric neurons and endothelial cells, and on both the apical and basolateral sides of enterocytes (Kong et al., 1997). Since trypsin present in the Gl lumen could activate PAR2 on apical surfaces, this receptor may provide a means by which the epithelium "senses" luminal processes. In the gut, motility and secretion are regulated by neurons of the submucosal and myenteric plexi of the gastrointestinal tract. These neurones express PARI , PAR2 and PAR4.
- PAR2 is expressed by secretomotor neurons in the submucosal plexus of the small intestine, where brief activation of PAR2 by agonists such as SLIGRL-NH 2 or trypsin results in a prolonged depolarisation that is often accompanied by increased excitability. Tryptase also induces a transient depolarization and a sustained increase in neuronal excitability (Linden et al., 2001 ). These observations indicate that PAR2 excites a proportion of myenteric neurons, which may contribute to dysmotility during intestinal inflammation.
- PAR2 activation is important in the establishment, maintenance, and progression of intestinal inflammation and of fibrosis.
- Psoriasis is a common skin condition which typically develops as patches
- a PAR2 antagonist will be effective in the treatment of inflammatory skin diseases including psoriasis and itch.
- topical or systemic administration of a PAR2 antagonist would reduce the itch caused by local inflammation in psoriasis, and therefore would constitute a targeted treatment for this unchallenged symptom of psoriasis.
- a PAR2 antagonist will be effective in the treatment of arthritis due to inflammation in or around the joint.
- the transmission of pain and/or unpleasant sensation is also enhanced by activation of PAR2 receptors as application of activating peptide excites C fibres and sensitises them to heat (Ding-Pfennigdorf et al., 2004).
- PAR-2 has been implicated in cellular proliferation, invasion and metastasis. There is increasing evidence that PAR2 is an important mediator of tumour progression, with trypsin levels being elevated in gastric, colon, ovarian and lung tumours (Ducroc et al., 2002). In addition PAR-2 is expressed in cancers of the lungs, liver, prostate, thyroid, breast, gastrium, colon, pancreas, gallbladder, melanoma and glioblastoma (see Jahan et al., 2007 and references therein).
- Tissue factor is a primary component of the clotting cascade which with
- Factor Vila or Factor Xa can initiate clotting. Cancer patients are frequently in a pro-thrombotic state, apparently partly due to the release of TF containing microparticles (small membranous fragments perhaps released on apoptosis). TF is expressed at high levels in vessel wall fibroblasts but may also be expressed on endothelial and smooth muscle cells (Kasthuri et al., 2009). TF is also heavily implicated in cancer, its expression generally increasing with cancer stage (Kakkar et al., 1995; Kasthuri et al., 2009) and appears to be involved in metastasis (Belting et al., 2005). Indeed TF may play a role in forming the fibrinous clot around metastatic cells which serves to protect them from NK cells and to maintain them in the vasculature (Palumbo et al., 2005, 2007).
- TF/Factor Vila/Factor Xa complexes stimulate breast carcinoma cell migration and invasion through activation of PAR2 (Hjortoe et al., 2004; Morris et al., 2006).
- activated PAR2 stimulates EGFR activity and thus cellular proliferation (Caruso et al., 2006); Darmoul et al., 2004).
- ovarian cancer increase in PAR-2 was seen with progression of the cancer irrespective of the histopathological classification of the tumour type, and high cancer cell PAR-2 expression was associated with a significantly worse prognosis (Jahan et al., 2007).
- Pancreatitis is an inflammatory condition understood to be the result of undesirable trypsin activity within the pancreas.

- Antagonism of the effects of trypsin at PAR2, within the pancreas, is expected to be an effective treatment for pancreatitis.'
- PAR2 receptor activation has been shown to be important in inflammatory disorders. Based on in vivo studies in models of inflammatory disorders (Kelso et al, JPET, 2006, 316, 1017-1024, Sevigny, PNAS, 201 1 , 108, 20, 8491 -8496 and Cenac et al, JDR, 2010, 89, 10, 1 123-1 128) it is expected that antagonism of the PAR2 receptor will be effective in the treatment of inflammatory disorders.
- the PAR2 receptor is regarded as a target for intervention in the treatment of the conditions referred to above.
- This invention makes available a class of compounds which are antagonists of the PAR2 receptor, and their use in indications which respond to the antagonism of the PAR2 receptor such as those mentioned above.

Trypsin (EC 50 concentration) was then added using the FLIPR and fluorescense recorded as described above. Curve-fitting and parameter estimation were carried out using GraphPad Prism 4.0 (GraphPad Software Inc., San Diego, CA).
- the kit quantifies trypsin activity by measuring the cleaved product of FTC-casein. To measure enzyme inhibition activity, compounds were pre-incubated with trypsin before the addition of substrate. Compound IC50 was determined as percentage inhibition of trypsin.
