Abstract

LR and [d-Gln4]LR Peptides bind the monomer-monomer interface of human Thymidylate Synthase and inhibit Cancer cell growth. Here, proline-mutated LR Peptides were synthesized. Molecular dynamics calculations and circular dichroism spectra have provided a consistent picture of the conformational propensities of the [Pro n]-peptides. [Pro3]LR and [Pro4]LR show improved cell growth inhibition and similar intracellular protein modulation compared with LR. These represent a step forward to the identification of more rigid and metabolically stable Peptides.
