摘要：

An organic layer prepared from the Chinese crude drug 'Sang-Bai-Pi' (Morus root bark) was studied in order to identify the inhibitory compounds for protein tyrosine phosphatase 1B (PTP1B). Bioassay-guided fractionation resulted in the isolation of sanggenon C (1), sanggenon G (2), mulberrofuran C (3) and kuwanon L (4) as PTP1B inhibitors, along with moracin O (5) and moracin P (6). Compounds 1-4 inhibited PTP1B with IC50 values ranging from 1.6 +/- 0.3 mu M to 16.9 +/- 1.1 mu M. (C) 2005 Elsevier Ltd. All rights reserved.
