Sirona Biochem's Skin Lightening Compounds Demonstrate Significant Antioxidant Properties

Marketwired

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jul 15, 2013) - Sirona Biochem Corp. (TSX VENTURE:SBM)(SRBCF)(ZSB.F), announced today its skin lightening compounds have shown to have significant antioxidant activity. The study was performed by Biogalenys, a France based company (www.biogalenys.com). Antioxidant testing measures the ability of a compound to inhibit the oxidation of other molecules. Insufficient levels of antioxidants can cause oxidative stress, which produces free radicals that can be toxic to parts of cells, potentially causing diseases. Antioxidants are being investigated for their abilities to prevent diseases.

In the study, the antioxidant potential of compounds TFC-849 and TFC-723 was evaluated using a standard DPPH assay, and their efficiency factors were determined. The antioxidant activity of the compounds was evaluated by determining resultant levels of IC50, a molar ratio showing the concentration of the antioxidant leading to 50% reduction of the initial DPPH concentration. Both of the company's compounds were proven to have free radical scavenging activity.

While both compounds were qualified as antioxidants, TFC-723 showed to be two times more efficient than both natural alpha and beta arbutin. Moreover, the free radical scavenging activity of TFC-723 was slightly higher than that of Ascorbic Acid Glucoside, commonly used in cosmetic products for this purpose.

"In scientific research, our compounds continue to demonstrate superior efficacy and safety and now show the added benefit of proven antioxidant properties," said Neil Belenkie, Chief Executive Officer of Sirona Biochem. "This is another exciting breakthrough and again raises the bar of quality in a multi-billion dollar industry," he added.
