摘 要: 在前期以天然产物岩芹酸为先导物而发现的新型小分子蛋白酪氨酸磷酸酶-1B(protein tyrosine phosphatase 1B,PTP1B)抑制剂N-(2-十四烷氧基苯基)邻氨甲酰基苯甲酸的基础上,将该抑制剂作为先导物进行进一步的优化,设计合成一系列取代的(2-十四烷氧基苯基)氨甲酰基邻苯甲酸类衍生物,进行PTP1B活性筛选。体外活性测试结果显示:多数化合物具有抑制PTP1B的活性,部分化合物IC50值达到100 nm 左右,并对上述化合物的构效关系进行总结。
关 键 词: 药物化学;烷氧基苯基氨甲酰基邻苯甲酸类衍生物;合成;构效关系;蛋白酪氨酸磷酸酶-1B

Abstract: Starting from the natural product petroselinic acid as lead compound, N-(2-tetradecanoxyphenylaminocarbonyl) benzoic acid was found as a small molecule protein tyrosine phosphatase 1B (PTP1B) inhibitor. For further modification, a series of (2-tetradecanoxyphenylaminocarbonyl) benzoic acid derivatives were designed and synthesized. The inhibitory activities of these compounds in vitro against PTP1B were evaluated. The results indicated that most of the derivatives showed more potent activities against PTP1B and IC50 of some compounds arrived at 100 nm in vitro. The structure-activity relationship (SAR) was summarized.
Key words: medicinal chemistry; (alkoxyphenyl)-aminocarbonyl benzoic acid derivatives; synthesis; structure-activity relationship; protein tyrosine phosphates 1B
