Definitions

• This invention relates to novel 8-(heteroarylmethoxy)quinoline compounds, compositions containing the same and the use of said compounds. These compounds act as selective modulators of bradykinin (BK) B2 receptors and can therefore be used in pharmaceutical compositions for the treatment of conditions responsive to BK B2 receptor modulation. Compounds of the invention are also useful as probes for the localization of BK B2 receptors and as standards in assays for BK B2 receptor binding.
• BK bradykinin
• Bradykinin is a vasoactive nonapeptide, H-Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe- Arg-OH, formed by the action of various plasma enzymes such as kallikrein on kininogens. In some aspects, it has some similar actions to that of histamine, and like histamine is released from venules rather than arterioles.
• BK receptors Two types are recognized in mammals, Bl and B2 (Leeb-Lundberg, et al Pharmacol. Rev. 2005, 57, 27-77).
• the actions of BK mediated by the B2 receptor are important physiological functions, such as increases in vascular permeability, modulation of inflammatory responses and pain as well as vasoactive effects (vasodilatation, vasoconstriction).
• These effects at the B2 receptor are responsible for BK's role in numerous diseases, such as inflammation, cardiovascular disease, and pain.
• agents that block the binding of BK to its B2 receptor can inhibit or at least alleviate the pathogenic events.
• BK B2 receptor antagonists Numerous peptide and non-peptide antagonists of BK B2 receptor have been described in the prior art. For instance, WO 2006/40004, WO 03/103671, WO 03/87090, WO00/23439, WO 00/50418, WO 99/64039, WO 97/41104, WO 97/28153, WO 97/07115, WO 96/13485, EP 0 795 547, EP 0 796 848, EP 0 867 432, and EP 1 213 289 disclose quinoline compounds that are BK B2 receptor antagonists.
