Definitions

• This invention relates to novel compounds that are useful as inhibitors of leukotriene A 4 hydrolase (LTA 4 H) and are thus useful for treating a variety of diseases and disorders that are mediated or sustained through the activity of leukotrienes including asthma, allergy and cardiovascular diseases including atherosclerosis, myocardial infarction and stroke.
• This invention also relates to pharmaceutical compositions comprising these compounds, methods of using these compounds in the treatment of various diseases and disorders, processes for preparing these compounds and intermediates useful in these processes.
• Leukotrienes are oxidized lipids that are produced by several cell types including neutrophils, mast cells, eosinophils, basophils, monocytes and macrophages.
• the first committed step in the intracellular synthesis of LTs involves oxidation of arachidonic acid by 5 -lipoxygenase (5-LO) to leukotriene A 4 (LTA 4 ), a process requiring the 5- lipoxygenase-activating protein (FLAP).
• Leukotriene A 4 hydrolase (LTA 4 H) catalyzes the hydrolysis of LTA 4 to produce leukotriene B 4 (LTB 4 ).
• LTB 4 Through the engagement of the LTB 4 receptors (BLT1, BLT2), LTB 4 stimulates an array of pro-inflammatory responses (leukocyte chemotaxis, cytokine release, etc.).
• the leukotriene pathway has been implicated in diseases in which inflammation is a critical component of the pathology; these include cancer, asthma, atherosclerosis, colitis, glomerularnephritis, and pain (for a review, see M. Peters-Golden and W.R. Henderson, Jr., M.D., N. Engl. J. Med., 2007, 357, 1841-1854).
• the present invention provides novel compounds which inhibit leukotriene A 4 hydrolase (LTA 4 H) and are thus useful for treating a variety of diseases and disorders that are mediated or sustained through the activity of leukotrienes, including allergic, pulmonary, fibrotic, inflammatory and cardiovascular diseases and cancer.
