Two novel 27-norergostanol steroids, panthogenins A （1） and B （2）, possessing unusual rings E and F featuring a ketal moiety at C-25 were isolated from rhizomes ofDioscorea panthaica. Their structures and relative...Two novel 27-norergostanol steroids, panthogenins A （1） and B （2）, possessing unusual rings E and F featuring a ketal moiety at C-25 were isolated from rhizomes ofDioscorea panthaica. Their structures and relative configurations were elucidated by extensive spectroscopic methods including 1D and 2D NMR techniques, and the structure of panthogenin A was further confirmed by X-ray crystallography. Both compounds showed potent in vitro insulin sensitizing activity.展开更多
A series of 2 benzyl 1,3 dicabonyl derivatives was synthesized. Their insulin sensitizing activity was evaluated in 3T3 L1 preadipocyte cells.

Their insulin sensitizing activity was evaluated in 3T3 L1 preadipocyte cells. Compounds 3, 26 and 27 were found to possess strong insulin sensitizing activity in vitro and were selected for further hypoglycemic evaluation in vivo.展开更多
