  Development of novel NLRP3-XOD dual inhibitors for the treatment of gout

  摘要：

  Gout is a crystalline-related arthropathy caused by the deposition of monosodium urate (MSU). Acute gouty arthritis is the most common first symptom of gout. Studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasome as pattern recognition receptors can be activated by uric acid crystallization, triggering immune inflammation and causing acute gouty arthritis symptoms. Currently, the treatment of gout mainly includes two basic methods: reducing uric acid and alleviating inflammation. In this paper, 22 novel benzoxazole and benzimidazole derivatives were synthesized from deoxybenzoin oxime derivatives. These compounds have good inhibitory effects on NLRP3 and XOD screened by our research group in the early stage. The inhibitory activities of XOD and NLRP3 and their derivatives were also screened. Notably, compound 9b is a multi-targeting inhibitor of NLRP3 and XOD with excellent potency in treating hyperuricemia and acute gouty arthritis.

  A general and expeditious approach for the copper mediated synthesis of multi‐functionalized dihydropyrazoles from N‐sulfonylhydrazones and sulfoxonium ylides has been achieved under aerobic oxidative conditions. The formal [4+1] cycloaddition reaction exhibits many notable features and can be easily scaled up to gram scale.

  A new and mild method for the generation of HF from triethylsilane and silver fluoride leads to a highly efficient one-pot synthesis of N−CF3 secondary amines. Novel N−CF3 sulfonamides were constructed from these promising amine building blocks and sulfonyl bromides in an unprecedented route.
