Figure 1.

Cytotoxicity profiles of small molecules listed in Table 1. BJ cells were treated with small molecules or dimethyl sulfoxide (DMSO) control for 4 h (A1–A3) or 16 h (B1–B3) followed by cell viability assay (0 h, black columns). Cells were further incubated in complete media without small molecules for another 48 h (grey columns) followed by a second cell viability assay. Cell viability results were normalized to respective DMSO controls in each experiment. # and φ indicate relative viability of <10% and <50% compared to DMSO controls, respectively.
