natural dihydroresorcylide (1) and making it more easily accessible for biological evaluation. The absolute configuration of C-3 in natural 1 was revised to be R by comparison of the rotation sign of synthetic (R)- and (S)-1. The synthetic (R)-1 was found to be a novel highly specific PTP1B inhibitor with an IC50 value of 17.06 μM.
本研究旨在为大环
内酯类化合物开发一种简明的合成路线,目的是确认天然二氢
间苯二酚(1)的绝对构型并使其更易于用于
生物学评估。C-3的天然1的绝对构型进行了修订,是- [R通过合成(的旋转符号的比较- [R )-和(小号)-1。发现合成的(R)-1是新型的高特异性
PTP1B
抑制剂,IC 50值为17.06μM。
