    • 2 incubator. After incubation, 10 μL of 5 mg/mL (50 μg) of MTT was added to above 100 μL of cell and incubated 4 h at the same condition. Then, the MTT is converted into water-insoluble crystals of formazan, which was dissolved by the addition of 100 L of 10% SDS containing 0.01 M HCl. After 12 h, the absorbance was measured at 595 nm using a Microplate reader (Bio-Rad, Model 680)

Fresh made DPPH radical solution (2 mL, final concn 100 μM) was added into each 1 mL of 4, 5, and probucol. The absorbance of DPPH radical remaining was measured at 517 nm against a blank of pure methanol including only DPPH radical for 20 min using the UV-vis spectrophotometer at room temperature. Radical DPPH scavenging capacity was calculated from the difference in absorbance with 4, 5, and probucol and expressed as percent DPPH radical remaining, according to the following equation: DPPH remaining=100 x(absorbance of sample/absorbance of control)
