After this growth period, 100 mg substrate in 1 ml acetone or DMSO was added to each flask and the incubation was continued for four days. Biotransformation of the substrates was monitored by TLC.

The next day compound at 100 μg/mL diluted in culture medium was added (200 μL/well) to the wells. 48 h later, 20 μL of MTT (Sigma Chemical Co., St. Louis, MO) (0.5 mg/mL MTT in PBS) was added and cells were incubated for a further 4 h. 200 μL DMSO was added to each culture to dissolve the reduced MTT crystals. The MTT-formazan product dissolved in DMSO was estimated by measuring absorbance at 570 nm with a microplate reader (Biotech, Power Wave, CA). Then the inhibitory percentage of each compound was calculated.
