(127) In-Vitro Cell Line Assay

MCF-7 Cell Growth Inhibition Assay

(128) MCF-7 cells were plated in 96 well plate in the presence of estradiol (1 nM) and incubated overnight. After 24 hours test compound was added at various concentrations and incubated for five days. On the fifth day, cell viability was evaluated using Presto Blue Cell Viability Reagent. Percentage growth inhibition was calculated as follows: 100−[(O.D. of sample)*100/O.D. of vehicle control] wherein O.D. is optical density.

(129) Compounds of Formula I mostly showed growth inhibition more than 50% at 3 micromolar concentrations.

(130) Table 3 provides % inhibition at 1 μM in MCF-7 cell growth inhibition assay for some of the representative compounds.
