The present invention relates to synthetic methods for the production of both optically active and racemic 5,5-disubstituted-3,4-dihydroxy-2(5H)-furanones; 5-[(4-aryl)-3-butynyl]-3,4-dihydroxy-2(5H)-furanones; 5-(2-arylthio)ethyl-3,4-dihydroxy-2(5H)-furanones; and 5-(2-aryloxy)ethyl-3,4-dihydroxy-2(5H)-furanones. This invention further relates to the use of the above mentioned compounds as anti-inflammatory agents through their action as mixed inhibitors of lipid peroxidation, 5-lipoxygenase, cyclooxygenase-1 and cyclooxygenase-2. The invention further relates to the use of such compounds in the treatment of chronic inflammatory disorders such as asthma, rheumatoid arthritis, inflammatory bowel disease, atherosclerosis, acute respiratory distress syndrome, and central nervous system disorders such as Alzheimer's and Parkinson's disease wherein reactive oxygen species and inflammatory mediators are contributing deleterious factors.
本发明涉及用于合成旋光活性和消旋5,5-二取代-3,4-二羟基-2(5H)-呋喃酮;5-[(4-芳基)-3-丁炔基]-3,4-二羟基-2(5H)-呋喃酮;5-(2-芳硫基)乙基-3,4-二羟基-2(5H)-呋喃酮;以及5-(2-芳氧基)乙基-3,4-二羟基-2(5H)-呋喃酮的生产的合成方法。本发明进一步涉及上述化合物作为抗炎药物的用途,通过它们作为脂质过氧化、5-脂氧合酶、环氧合酶-1和环氧合酶-2的混合抑制剂的作用。该发明还涉及将这些化合物用于治疗慢性炎症性疾病,如哮喘、类风湿性关节炎、炎症性肠病、动脉粥样硬化、急性呼吸窘迫综合征,以及阿尔茨海默病和帕金森病等中枢神经系统疾病,其中活性氧自由基和炎症介质是造成有害因素的。
