A series of water-soluble PEGylated 1,2,4-triazoles – were successfully synthesized from methyl 5-(chloromethyl)-1-aryl-1-1,2,4-triazole-3-carboxylates . All of the water-soluble PEGylated 1,2,4-triazoles were characterized by FT-IR and H NMR spectroscopy. The solubility, plasma stability, and anti-inflammatory activity were also determined and compared to original methyl 5-(halomethyl)-1-aryl-1-1
由5-(氯甲基)-1-芳基-1-1,2,4-三唑-3-羧酸甲酯成功合成了一系列水溶性聚乙二醇化1,2,4-三唑。所有水溶性聚乙二醇化 1,2,4-三唑均通过 FT-IR 和 1H NMR 光谱进行表征。还测定了溶解度、血浆稳定性和抗炎活性,并与原始 5-(卤甲基)-1-芳基-1-1,2,4-三唑-3-羧酸甲酯进行比较。对于 SAR 研究,所有聚乙二醇化 1,2,4-三唑对 LPS 诱导的 RAW 264.7 细胞均具有潜在的抗炎活性 (IC = 3.42–7.81 μM)。此外,Western blot结果显示,聚乙二醇化1,2,4-三唑对iNOS和COX-2表达的抑制活性分别是5.43倍和2.37倍。另一方面,细胞活力研究表明,聚乙二醇化1,2,4-三唑且PEG分子量超过600时,具有更好的细胞安全性(细胞活力> 95%)。通过溶解度和血浆稳定性研究,聚乙二醇化 1,2,4-三唑 - 表
