Cell viability analysis after treatment with compounds N2, N7 and PB.

<p>The compounds were tested at concentrations ranging from 0.1 to 100 μM, for 24 h in MCF7 and HepG2 cells, as indicated in the panels). Cell viability (%) was calculated as the ratio between cell incubated with compound and cell incubated with DMSO. Each point represents the mean ± standard deviation, with n = 2 replicates.</p> <p>(DOCX)</p>
