  • 3. Patent number: PCT/IB2009/055439. Peptides binding to the dimer interface of thymidylate synthase for the treatment of cancer. M. P.Costi, G. Ponterini, G. Marverti, D. Cardinale, A. Venturelli, S. Ferrari. Titolare: UNIMORE, EML. The present invention relates to peptides binding to the thymidylate synthase protein, in particular to human thymidylate synthase (hTS) protein, for the treatment of cancer. The present invention relates to peptides that can bind at a binding site located at the interface of thymdylate synthase protein. These peptides range from 3 to 10, preferably 4-8 amino acids and have a sequence that binds to each subunit of the thymidylate synthase dimer at the level of dimer interface, stabilizing the dimeric inactive form of the thymdylate synthase enzyme. In addition, the present invention relates to pharmaceutical compositions comprising these compounds as active agents, and uses thereof for the treatment of cancer and to reverse or/and be active in cancer drug resistance
  • 4. Patent number: MI2009A002117. Struttura del cristallo del complesso di Timidilato Sintetasi (TS) con un ligando. S. Mangani, C. Pozzi, S. Ferrari, M. P. Costi. Titolare: UNIMORE , Università di Siena. The inventors have discovered that some "small" peptides with a sequence consisting of 3 to 10 amino acids inhibit Thymidylate synthase protein by binding to a new site located at the interface of dimerization of the protein able to stabilize the inactive conformation of the protein. The discovery of this new binding site and of the peptide that can bind to it made it possible to verify the existence of a new mechanism of inhibition of tumor cells (particularly ovarian cancer cells) in which the catalytic function of Thymidylate synthase is inhibited (through stabilization of its inactive form) without at the same time, blocking its function of gene translation. This new mechanism allows to avoid the accumulation of high concentrations of Thymidylate synthase in cancer cells, responsible for the onset of classic drug-resistant to platinum-based drugs. Consequently, this discovery helps provide a new tool for designing new Thymidylate synthase inhibitors useful in the treatment of cancer and particularly advantageous to reverse the resistance of tumor cells to traditional anticancer agents. From the practical point of view, the patent application on peptides find use in the marketing of specific inhibitors for therapeutic indications described above.
