Sirona Biochem Corp. (TSX-V: SBM) announced it is now ready to begin testing its novel new compounds to fight diabetes and obesity.

The completion of the company's key SGLT biological assessment test and testing will be done under contract with Richmond, BC based SignalChem.

Sirona Biochem owns the worldwide rights to a library of potential new sodium glucose transporter (SGLT) inhibitors developed to treat diabetes and obesity. SGLT Inhibitors are a novel new drug class currently under development that block the reuptake of excess sugars from urine in the kidney which can then reduce high blood sugar to normal levels. Excess sugar in the blood is a primary medical challenge associated with treating diabetes and obesity.

Sirona has a research and development agreement with TFChem (Rouen, France), where a significant number of SGLT drug analogs are being prepared for first stage evaluation. Preliminary primary stage testing conducted earlier this year provided positive indications to support Sirona Biochem's project and provided key insights to optimize the new test that is now ready for use to evaluate the next library set of molecules.

Mark Senner, President, explained, "SGLT inhibitors are a new and exciting class of compounds that have great promise to treat both diabetes and obesity which are now at epidemic levels worldwide. This new drug class is one considered to have extraordinary market potential in the fight against diabetes and obesity.

"Development of this new drug class however is challenging due to the fragile nature of these 'sugar' based molecules that render them unstable and difficult to develop for clinical use. Given this challenge, it is believed that the use of the patented GlycoMim® technology, licensed from TFChem to develop SGLT Inhibitors, will increase drug stability and, therefore, improve their overall clinical effectiveness. Potential licensing and development partners have expressed interest in our concept of improving molecules in this new drug class. We intend to develop 'best in class' SGLT Inhibitors through use of this technology.

"The key and critical first test has been developed and optimized for use by SignalChem under contract from Sirona Biochem. Through use of this proprietary test, the company will be able to determine which molecules have the desired potency and selectivity compared to a reference standard. Screening of the current library of compounds will generate key data for ongoing drug development and provide first stage proof of concept necessary to secure future partnering opportunities. Sirona's scientific team aims to identify lead compounds by the end of 2009," continued Senner.

"The results from our new optimized test will be critical to direct our ongoing development of novel new SGLT inhibitors. The development and optimization of this sophisticated test, completed by SignalChem, is a significant and key milestone achievement for us. We are very pleased with the progress that we are making on our SGLT drug development program," commented Senner.

Upon selection of compounds with the desired potency and selectivity for the SGLT 2 carrier protein, further preclinical screening for cytotoxicity, ADME properties, pharmacokinetics and in vivo efficacy will need to be carried out to select compounds for future clinical development. The primary objective of this critical first stage development plan with SignalChem was to develop, qualify and optimize the key test required for the initial development of SGLT inhibitors.
