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.File in questo prodotto:
