Sirona Biochem Corp. (TSX-V: SBM), an emerging biotech company focused on diabetes and obesity, announced today that it has now taken delivery of its first batch of unique SGLT compounds from its French partner TFChem (Rouen, France) for screening and evaluation.

"The successful production of these new molecules marks a significant company milestone," said CEO, Dr. Howard Verrico.

Sirona Biochem owns the worldwide product rights to a library of sodium glucose transporter (SGLT) inhibitors to treat diabetes and obesity. SGLT Inhibitors block the reuptake of excess sugars from urine in the kidney which can then reduce high blood sugar to normal levels.

It's estimated that there are nearly 21 million people in the United States, or 7% of the population, who are diabetic. About 15 million have been diagnosed with the disease, but over 6 million people are unaware that they are suffering from it. It is forecast that by 2025, 333 million people will have diabetes.

Management of sugar metabolism is a primary medical challenge associated with treating diabetes and obesity.

Dr. Verrico explained that, "As far as we have been able to verify, these are a truly unique group of SGLT inhibitors in the world. To our knowledge, TFChem is the first to synthesize these uniquely designed molecules. SGLT inhibitors are a new and exciting class of compounds that have great promise for the treatment of diabetes and obesity.

"This new drug class is one considered to have substantial market potential in the fight against diabetes and obesity, particularly if we can prove our versions to be robust enough to survive the journey through the body and result in reduced blood sugar levels.

"The test results will then enable us, through ongoing refinement of molecular development, to identify our lead compounds for in vivo testing projected to start early next year," concluded Dr. Verrico.

The tests were developed by SignalChem (Richmond, BC). Sirona's scientific team aims to identify lead compounds by the end of 2009.
