Abstract
To date the somatostatin analogues are the object of interest as potential antitumor agents. A number of somatostatin-like compounds were synthesized. They are used in the therapy of neuroendocrinal tumors, the potential of their use in the therapy of other tumors is being actively investigated.
Here, we studied the mechanism of antitumor action of a novel somatostatin analogue cifetrelin on in vitro cultured breast cancer cells MCF-7. We found that cifetrelin has an increased cytostatic activity compared to somatostatin. In the lower concentrations, that do not cause growth inhibition, cifetrelin significantly promotes the apoptosis, induced by adriamycin. We have revealed, that cytostatic activity of cifetrelin is the result of apoptosis induction, apoptosis is p53-independent and is accompanied by the early NF-kB inhibition. In general, the data obtained demonstrate a high level of antitumor activity of cifetrelin in breast cancer cells. The further studies are required to elicit the mechanism of cifetrelin action and its possible use in therapy of malignant diseases.
