TT-232 is a structural analogue of somatostatin, a hormone with significant, selective antiproliferative, anti-inflammatory and antisecretory properties. In contrast to the parent hormone and its “traditional” analogues, this compound has strong and specific growth-inhibitory potential without the wide-ranging endocrine side-effects, including inhibition of insulin secretion provoking diabetes. Its mechanism of action is in line with the so-called signal-transduction therapy, where "internal communication" of cells is corrected without interfering with basic cell functions and machinery. Moreover, TT-232 acts on pyruvate kinase translocation and neurogenic inflammation. In vitro and in vivo studies show a selective antitumor activity with induction of strong apoptosis of cancer cells.
