以吲哚丁酸为原料,通过酯化、酰肼化、环化、取代四步反应得到了一系列吲哚丙基-1,3,4-噁二唑衍生物.对所合成的目标化合物进行了抗蛋白酪氨酸磷酸酯酶1B(PTP1B)活性测试,发现其中5个化合物具有明显的体外抗PTP1B活性,其中化合物5g活性最强,其IC_(50)为6.74μg·mL^-1.该系列化合物是首次报道的具有PTP1B抑制活性的吲哚烷基-噁二唑衍生物.
A series of indolepropyl based 1,3,4-oxadiazole derivatives were synthesized by esterification, hydrazidation, cyclization and substitution using indolebutyric acid as starting material. The inhibitory activity against protein tyrosine phosphatase 1B(PTP1B) was evaluated. The results indicated that five compounds displayed obviously inhibitory effect against PTP1 B in vitro, for instance, compound 5g exhibited the strongest PTP1 B inhibitory activity with an IC_(50) value of 6.74 μg·m L~(-1). It was the first example of indolealkyl based oxadiazole derivatives showing PTP1 B inhibitory activity.
