摘要:
Five selective 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) competitive inhibitors, hupehenols AE (1-5), were isolated from Viburnum hupehense. The structure elucidation indicated that compounds 1-5 are new 20,21,22,23,24,25,26,27-octanordammarane triterpenoids. Their structures were established on the basis of NMR spectroscopic and mass spectrometric analysis. Hupehenols AE (1-5) showed inhibition against human 11 beta-HSD1, with hupehenols B (2) and E (5) having IC50 values of 15.3 and 34.0 nM, respectively. Moreover, hupehenols C (3) and D (4) are highly selective inhibitors of human 11 beta-HSD1 when compared to murine 11 beta-HSD1.T
