    • note
    • Pure compounds were initially dissolved in DMSO at 400 times the desired final maximum test concentration, that is, 100 μM. Control cells were exposed to an equivalent concentration of DMSO. Each agent was tested in duplicate at five different 10-fold dilutions. Drug incubation times were 48 h, after which cells were precipitated with 50 μL ice-cold 80% (w/v) trichloroacetic acid (HL60) or 25 μL ice-cold 50% (w/v) trichloroacetic acid (MCF7) and fixed for 60 min at 4°C. Then the SRB assay was performed. The optical density (OD) of each well was measured at 490 nm using Bio-Tek's Elx800 NB 96-well plate reader. The percentage growth was calculated at each of the drug concentration levels based on the difference in OD at the start and end of drug exposure. Values were corrected for background OD from wells only containing medium.

    • Software-predicted lipophilicity of the compounds was calculated with the program CLOGP accessible via Internet (www.daylight.com/daycgi/clogp ) working with the Hansch-Leo's "fragment constant" method.
