Problems solved by technology

However, these drugs not only have serious side effects, but also have no therapeutic effect on the acute attack of gout
In December 2015, the FDA just approved Zurampic, a new drug for the treatment of gout. Although its combination with xanthine oxidase inhibitors can well control the content of serum uric acid, it also has renal and cardiovascular safety risks
In terms of anti-inflammatory drugs, clinically commonly used western medicines such as colchicine, non-steroidal anti-inflammatory drugs and glucocorticoids can be used to relieve acute gouty arthritis, but these drugs are used in large amounts and have many side effects. intolerable
Although the emerging interleukin-1 (IL-1) receptor blocker Rilonacept and anti-IL-1β monoclonal antibody Canakinumab can significantly relieve the joint symptoms of gout patients who are ineffective or intolerable to conventional anti-inflammatory analgesic treatment, but Its research and development costs are expensive, the way of administration is limited, and there are serious safety problems

Description

technical field [0001] The invention belongs to the field of pharmaceutical technology, in particular to curcumin α, β-unsaturated cyclic ketone derivatives ((2E,6E)-2-(3,5-dimethoxyphenylmethylene)-6-(4 The new application of -chlorophenylmethylene) cyclohexanone and its derivatives), especially its application in the preparation of medicines for the treatment of hyperuricemia and acute gouty arthritis. Background technique [0002] Hyperuricemia is a common metabolic disease that seriously endangers human health caused by increased uric acid synthesis or decreased uric acid excretion. Recent studies have found that elevated blood uric acid is an independent risk factor for kidney disease, and may be a pathogenic factor for kidney disease. Gout is a crystal-associated arthropathy caused by the deposition of monosodium urate (MSU), which is directly related to hyperuricemia caused by purine metabolic disorders and / or decreased uric acid excretion, and is a metabolic disease...
