Sirona Biochem Discovers Unexpected Ancillary Effects of Its Anti-Aging Compound

VANCOUVER, BC--(Marketwired - May 20, 2015) - Sirona Biochem Corp. (TSX VENTURE: SBM) (FRANKFURT: ZSB) is pleased to announce that its lead anti-aging compound also shows antioxidant properties in early preclinical studies.

As part of the anti-aging project, the Company has selected several potential lead compounds. One of these, SBM-TFC-837, showed a significant preservative effect against different stressors, such as starvation or ultraviolet radiation. Studies now indicate that SBM-TFC-837 also shows high preservative effect against oxidative stress induced by H₂O₂.

Oxidative stress response in humans causes free radicals which can damage cells and genetic material. The effect on cells can be degeneration, aging and various disease states. Antioxidants prevent this damage.

"An antioxidant effect on cells is a huge plus for our glycoprotein program for anti-aging," said Attila Hajdu, Chief Business Development Officer of Sirona Biochem. "If aging is the result of oxidative stress that leads to further cell damage, these new results suggest multiple mechanisms by which our glycoproteins exert their protective effects. This discovery will certainly be beneficial to our current partnering discussions."

Further studies are ongoing and will continue to assess cell stressors and viability. The compounds may have applications in:

• Anti-aging cosmetic product since 80% of visible aging is directly related to cell death
• Cryopreservation
• Regenerative and protective cosmetic or pharmaceutical product for healing, wound care, hypothermic protection, sunscreen, post burn / radiotherapy
• Regenerative and protective pharmaceutical product against stress response in renal reperfusion and the improvement of engraftment
• Pharmaceutical product used in organ transplantation solution (for example Wisconsin solution)
• Regenerative and preservative product for preservation of stem cells, beta-islet cells, red blood cells, adipocytes and platelets as well as tissues including reconstituted human epithelial cells, skin explants and cornea
• Preservative for vaccines

The global anti-aging market is forecast to reach up to $345.8 billion US in 2018 from $249.3 billion in 2012. The related market for regenerative medicine, which aims to restore functional ability to tissues and organs, is set to hit $67.6 billion US in 2020.

We would like to acknowledge and thank Bpifrance and the region Haute Normandie for their ongoing support on the anti-aging project
