and thiazole derivatives have many biological functions, especially in the aspect of anti-inflammation. According to the strategy of pharmacophore combination, we introduced thiazole moiety into dihydropyrazole skeleton to design and synthesize a novel series of 2-(3,5-diphenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-methylthiazole derivatives, and evaluated their anti-inflammatory activities for sepsis treatment
全身炎症反应综合征是脓毒症的一个主要特征,脓毒症是全世界主要的死亡原因之一。据报道,3,5-二芳基-4,5-二氢吡唑和噻唑衍生物具有许多生物学功能,特别是在抗炎方面。根据药效团结合的策略,我们将噻唑部分引入二氢吡唑骨架,设计合成了一系列新型2-(3,5-diphenyl-4,5-dihydro-1 H -pyrazol-1-yl)-4-甲基噻唑衍生物,并评估了它们在脓毒症治疗中的抗炎活性。通过它们对 LPS 诱导的 RAW264.7 细胞中一氧化氮 (NO) 释放的抑制活性和最佳化合物E26进行初步构效关系 (SAR) 分析表现出比阳性对照治疗消炎痛和地塞米松更有效的抗炎活性。在进一步的机制研究中,我们的结果表明,化合物E26显着抑制白细胞介素-1β (IL-1β)、肿瘤坏死因子-α (TNF-α)、NO 的产生,并抑制诱导型一氧化氮合酶 (iNOS) 的表达, cyclooxygenase-2
