蛋白酪氨酸磷酸酯酶1B (PTP1B)是治疗糖尿病的潜在靶标.通过向天然五环三萜类化合物白桦脂醇的3位引入5-取代苯基-3-异噁唑,设计并合成了系列结构新颖的化合物,并通过1H NMR、13C NMR和HRMS鉴定了其结构.生物活性筛选结果表明,所得目标化合物均具有较好的PTP1B抑制活性,其中化合物15h的IC50达到0.98 μmol·L-1,为先导化合物白桦脂醇活性的12倍左右,同时该化合物对高度同源的T细胞蛋白酪氨酸磷酸酶(TCPTP)的选择性也达到4倍左右.

Protein tyrosine phosphatase-1B (PTP1B) is recognized as a potent target for the therapy of diabetes. By introducing substituted 5-phenyl-3-isoxazole ring to the 3-position of betulin, a series of novel compounds were designed, synthesized and characterized by 1H NMR, 13C NMR and HRMS. The results of bioassays exhibited that most of the titled compounds were active to PTP1B. Among them, compound 15h has an IC50 of 0.98 μmol·L-1 against PTP1B and a 4-fold selectivity over T cell protein tyrosine phosphatase (TCPTP).
