clove buds known for its pharmacological activities such as anti-inflammatory, antidiabetic, antioxidant, and anticancer activities. It is well known from the literature that peroxisome proliferator-activated receptors (PPARγ) have been reported to regulate inflammatory responses. In this backdrop, we rationally designed semi-synthetic derivatives of eugenol with the aid of computational studies, and synthesized
丁子香酚是丁香花蕾中大量存在的天然产物,以其抗炎、抗糖尿病、抗氧化和抗癌等药理活性而闻名。从文献中众所周知,过氧化物酶体增殖物激活受体(PPARγ)已被报道可调节炎症反应。在此背景下,我们借助计算研究合理设计了丁香酚半合成衍生物,合成、纯化并分析了四种作为PPARγ激动剂的丁香酚衍生物。通过时间分辨荧光 (TR-FRET) 测定筛选化合物的 PPARγ 蛋白结合。生化检测结果对 1C 有利,与 IC50 值为 1.052 μM 的标准吡格列酮相比,1C 表现出显着的结合亲和力,IC50 值为 10.65 μM。除了蛋白质结合研究之外,作为功能测定,还筛选了合成的丁香酚衍生物在浓度范围为 6.25 μM 至 400 μM 时的体外抗炎活性。在测试的四种化合物中,1C 显示出相当良好的抗炎活性,IC50 值为 133.8 μM,而标准双氯芬酸钠 IC50 值为 54.32 μM。结构-活性关系
