metabolites of marine microorganisms. Butyrolactone I was found to be produced by Aspergillus terreus isolated from several marine-derived samples. The hypoglycemic activity of butyrolactone I has aroused our great interest. In this study, we synthesized six racemic butenolide derivatives (namely BL-1–BL-6) by modifying the C-4 side chain of butyrolactone I. Among them, BL-3 and BL-5 improved the insulin
近年来,已经从海洋微生物的次生代谢物中分离出了许多含有丁烯内酯官能团的药理活性化合物。发现丁内酯由土曲霉产生从几个海洋样本中分离出来。丁内酯I的降血糖活性引起了我们的极大兴趣。在这项研究中,我们通过修饰丁内酯I的C-4侧链合成了六种外消旋丁烯内酯衍生物(即BL-1–BL-6)。其中BL-3和BL-5改善了HepG2细胞的胰岛素抵抗,并不影响RIN-m5f细胞系的增殖,这表明BL-3和BL-5的功效和安全性。此外,BL-3,BL-4,BL-5和BL-6表现出显着的蛋白质酪氨酸磷酸酶1B(PTP1B)抑制作用,而BL-3的对映异构体表现出不同的50%百分比抑制浓度(IC 50)针对PTP1B的值。BLs和PTP1B分子对接模拟的结果解释了BL-3对映异构体之间观察到的生物学结果的差异,该对映异构体支持BLs作为PTP1B抑制剂,并且还表明C-4的手性可能会影响Cb-1的抑制作用BL。我们的发现
