activity was assayed too, using the popular 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay (see ESI Section S11). Fibroblast cells displayed analogous metabolic activity for the samples that were untreated and served as controls, relative to those that were treated with serial dilutions of peptides 1-3 (1.00 mM -62.5 µM). The manuscript was written through contributions of all authors. All authors have given approval to the final version of the manuscript.
