Tanshinlactones and derivatives

Oxasteroids with a structure containing an C-17 steroid skeleton, with two oxygen atoms replacing carbon atoms, and one C=O group. They all have one nitrogen atom at the 15-position. Some tanshinlactones have the second oxygen atom at the 11-position and a C=O group at the 12-position. Others have the second oxygen atom at the 12-position and a C=O group at the 11-position.
