Background:
Ophiopogonin D', isolated from the tubers of Ophiopogon japonicus, is a rare naturally occurring C29 steroidal glycoside. Ophiopogonin D' shows cytotoxic activity against two human tumor cell lines MG-63 and SNU387 with IC50s of 3.09 μM and 3.63 μM, respectively[1]. Ophiopogonin D' activates SIRT1 in a dose-dependent manner[2].
