Peptoid Cytotoxicity in cancer cell lines and control cells.

LC50 means lethal concentrations causing 50% of the cell death. The maximum peptoid and peptide concentration tested was 100 µM. Cell viability was measured via MTS assay in cells treated with compounds for 72 h, and LC50 of peptoids was derived from peptoids' viability curves. HC10 **, concentration causing 10% hemolysis of human red blood cells, all the numbers were cited from [25]. “—”, data not measured. Peptoids labeled with asterisk have been reported previously to possess antimicrobial activities [23], [24], [25].
