Also disclosed is the treatment of chemokine-mediated diseases, where the chemokine binds to CXCR2 and/or CXCR1 receptor, using compounds of the formula I. The diseases include chronic inflammation, acute inflammatory pain, chronic inflammatory pain, acute neuropathic pain, chronic neuropathic pain, psoriasis, atopic dermatitis, asthma, COPD, adult respiratory disease, arthritis, inflammatory bowel disease, Crohn’s disease, ulcerative colitis, septic shock, endotoxic shock, gram neg. sepsis, toxic shock syndrome, stroke, cardiac and renal reperfusion injury, glomerulonephritis, thrombosis, Alzheimer’s disease, graft vs. host reaction, allograft rejections, malaria, acute respiratory distress syndrome, delayed type hypersensitivity reaction, atherosclerosis, cerebral and cardiac ischemia, osteoarthritis, multiple sclerosis, restenosis, angiogenesis, osteoporosis, gingivitis, respiratory viruses, herpes viruses, hepatitis viruses, HIV, Kaposi’s sarcoma associated virus, meningitis, cystic fibrosis, preterm labor, cough, pruritis, multiorgan dysfunction, trauma, strains, sprains, contusions, psoriatic arthritis, herpes, encephalitis, CNS vasculitis, traumatic brain injury, CNS tumors, and subarachnoid hemorrhage. They also include post surgical trauma, interstitial pneumonitis, hypersensitivity, crystal induced arthritis, acute and chronic pancreatitis, acute alc. hepatitis, necrotizing enterocolitis, chronic sinusitis, angiogenic ocular disease, ocular inflammation, retinopathy of prematurity, diabetic retinopathy, macular degeneration with the wet type preferred and corneal neovascularization, polymyositis, vasculitis, acne, gastric and duodenal ulcers, celiac disease, esophagitis, glossitis, airflow obstruction, airway hyperresponsiveness, bronchiectasis, bronchiolitis, bronchiolitis obliterans, chronic bronchitis, cor pulmonae, cough, dyspnea, emphysema, hypercapnea, hyperinflation, hypoxemia, hyperoxia-induced inflammations, hypoxia, surgical lung volume reduction, pulmonary fibrosis, pulmonary hypertension, right ventricular hypertrophy, peritonitis associated with continuous ambulatory peritoneal dialysis (CAPD), granulocytic ehrlichiosis, sarcoidosis, small airway disease, ventilation-perfusion mismatching, wheeze, colds, gout, alc. liver disease, lupus, burn therapy, periodontitis, transplant reperfusion injury and early transplantation rejection, acute inflammation, and rheumatoid arthritis as well as cancer. The compounds I had IC50 of <10 μM for inhibiting the binding of [125I]-IL-8 to human chemokine receptor CXCR1. The experimental process involved the reaction of 8-Methoxy-3,4-dihydroisoquinolin-1(2H)-one(cas: 74904-29-3).Product Details of 74904-29-3
