Alpha (α)-tomatine (simply tomatine) is the major saponin and occurs naturally in tomatoes, possesses a variety of biological properties including antioxidant, and anti-inflammatory. In additıon, tomatine is also known that it breaks down the cell membrane induces growth inhibition and apoptosis in different cancer cells: myeloid leukemia cells; prostate cancer cells; lung adenocarcinoma cells. However, the mechanisms of α-tomatine actions were not well understood. Nevertheless, was shown, that tomatine inhibited the NF-κB and phosphatidyl-inositol-3-kinase/Akt signaling pathways activation. However, the primary cellular target(s) for α-tomatine and its mechanisms for modulating apoptosis-associated pathways remain to be elucidated. The interaction of α-tomatine with cholesterol and the disruptive effect on the cell membrane may be one of the mechanisms by which α-tomatine induces apoptosis. The formation of complexes of α-tomatine and cholesterol may modulate the responsiveness of cell membrane receptors to growth stimuli and thus decrease the growth of cancer cells. Moreover, the anti-inflammatory mechanisms of α-tomatine, which may be a valuable therapeutic agent in the treatment of inflammation-related diseases was due to the ability of tomatine accelerated the phosphorylation of Akt in macrophages.

Sample Use Guides
Male severe combined immunodeficient (SCID) mice bearing PC-3 xenograft tumors were treated with i.p injections with vehicle (5 μl/g body weight), α-tomatine (5 mg/kg), curcumin (5 mg/kg), or α-tomatine (5 mg/kg) + curcumin (5 mg/kg) three times a week for 30 days.
Route of Administration:
Intraperitoneal
There was evaluated the effect of tomatine on cytotoxicity, apoptosis and matrix metalloproteinase inhibition in MCF-7 cell lines. Human breast cancer cell line (MCF-7) was used as a cell line. In MCF-7 cells, the IC50 dose of tomatine was determined to be 7.07 μM. According to the control cells, apoptosis increased 3.4 fold in 48thh. Activation of MMP-2, MMP-9 and MMP-9\NGAL has been shown to decrease significantly in cells treated with tomatine by gelatin zymography compared to the control. As a result, matrix metalloproteinase activity and cell proliferation were suppressed by tomatine
