forskolin (FSK) and
trilostane, were obtained from Sigma–Aldrich, South Africa, while 11β-hydroxyandrostenedione (11OH-A4) was purchased from Steraloids, USA. All test compounds, as well as FSK, were prepared in dimethylsulfoxide (DMSO), and added to the culturing medium at a final concentration of 0.2% DMSO. The deuterated internal standards, d2-
testosterone, d9-Prog, d9-17OH-Prog and d4-
cortisol were purchased from Cambridge Isotope Laboratories (Maryland, USA).
