Dihydroxy stilbene derivatives were designed based on lithospermic acid B and were prepared from 4-(chloromethyl)benzoic acid. The inhibitory activities of the novel compounds against protein tyrosine phosphatase 1B (PTP1B) were evaluated. 3,4-Dihydroxy stilbene carbonyl compounds (7, 11b, 27b) inhibited PTP1B with IC50 values comparable to molybdate, while the conjugation-extended compound (15b) showed
二羟基二苯乙烯衍生物是基于精酸B设计的,由4-(氯甲基)苯甲酸制备。评估了新化合物对蛋白酪氨酸磷酸酶 1B (PTP1B) 的抑制活性。3,4-二羟基芪羰基化合物 (7, 11b, 27b) 抑制 PTP1B 的 IC50 值与钼酸盐相当,而缀合扩展化合物 (15b) 的抑制作用比临床前 RK682 高 3 倍。将吸电子基团或酰胺引入第二个苯环,或将共轭延伸到二苯乙烯分子中,可以提高生成自由基的稳定性。
