The invention relates to synthetic peptide amide ligands of the kappa opioid receptor and particularly to agonists of the kappa opioid receptor that exhibit low PCYP inhibition and low penetration into the brain. The synthetic peptide amides of the invention conform to the structure: The compounds are useful in the prophylaxis and treatment of pain and inflammation associated with a variety of diseases and conditions.

Synthetic peptide amides and dimers thereof

The invention relates to synthetic peptide amide ligands of the kappa opioid receptor and particularly to agonists of the kappa opioid receptor that exhibit low PCYP inhibition and low penetration into the brain. The synthetic peptide amides of the invention conform to the structure of formula I: These compounds are useful in the prophylaxis and treatment of pain and inflammation associated with a variety of diseases and conditions.

Synthetic peptide amides

The invention relates to synthetic peptide amide ligands of the kappa opioid receptor and particularly to agonists of the kappa opioid receptor that exhibit low PCYP inhibition and low penetration into the brain. The synthetic peptide amides of the invention conform to the structure of formula I: Pharmaceutical compositions containing these compounds are useful in the prophylaxis and treatment of pain and inflammation associated with a variety of diseases and conditions. Such treatable pain includes visceral pain, neuropathic pain and hyperalgesia. Inflammation associated with conditions such as IBD and IBS, ocular and otic inflammation, other disorders and conditions such as pruritis, edema, hyponatremia, hypokalemia, ileus, tussis and glaucoma are treatable or preventable with the pharmaceutical compositions of the invention.

The invention relates to methods of use of synthetic peptide amides that are ligands of the kappa opioid receptor in the treatment and prevention of kappa opioid receptor-associated diseases and conditions; and particularly to uses of these agonists in the prophylaxis, inhibition and treatment of pain, inflammation and pruritis associated with a variety of diseases, disorders and conditions. Inflammatory conditions preventable or treatable by the methods of the invention include diseases and conditions associated with elevated levels of a proinflammatory cytokines, such as TNF-&#x3b1;, IL-1&#x3b2;, IL-6, MMP-1 and MMP-3. Such diseases and conditions include cardiovascular inflammation, neurological inflammation, skeletal inflammation, muscular inflammation, gastrointestinal inflammation, ocular inflammation, otic inflammation, inflammation due to insect bites and inflammation due to wound healing; atherosclerosis, ischemia, restenosis and vasculitis; of asthma, Sjogren's syndrome, pulmonary inflammation, chronic airway inflammation and chronic obstructive pulmonary disease (COPD), allergy, psoriasis, psoriatic arthritis, eczema, scleroderma, atopic dermatitis and systemic lupus erythematosus, arthritis, synovitis, osteomyelitis, rheumatoid arthritis, osteoarthritis and ankylosing spondylitis; septicemia and septic shock, diabetes, glucose intolerance, insulin resistance and obesity, colitis, ulcerative colitis, Crohn's disease, IBD and IBS, and the inflammatory diseases and conditions due to tumor proliferation, tumor metastasis or transplantation rejection.
