Design and synthesis of paracaseolide A analogues as selective protein tyrosine phosphatase 1B inhibitors†
Abstract
A series of structurally related analogues of the natural product paracaseolide A were synthesized and identified as potent PTP1B inhibitors. Among these analogues, compound 10 in particular showed improved PTP1B enzyme inhibitory activity, high selectivity for PTP1B over TC-PTP, and improved cellular effects.
