description

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.

Indocyanine green (ICG) is a near-infrared fluorescence imaging dye. Absorption maximum is at 800 nm and there is slight absorption in the visible range, which results in low auto-fluorescence and tissue absorbance. Emission maximum is at 810 nm. ICG has been approved by the FDA.
