Lorus Therapeutics Announces Publication on Development of Novel Antibacterial Compounds From Its Small Molecule Program

Potent Antibacterial Activity Demonstrated in Multi-Drug Resistant Bacterial Strains

TORONTO, ONTARIO--(Marketwire - Sept. 13, 2010) - Lorus Therapeutics Inc. (TSX:LOR)(OTCBB:LRUSF) ("Lorus"), a biopharmaceutical company specializing in the discovery and development of pharmaceutical products and technologies for the management of cancer, today announced the publication of a peer-reviewed scientific article describing synthesis and antibacterial activity of novel antimicrobial compounds from Lorus' small molecule program. 

The article entitled "Potent antimicrobial activity of 3-(4,5-diaryl-1H-imidazol-2-yl)-1H-indole derivatives against methicillin-resistant Staphylococcus aureus" was published in the peer-reviewed journal Bioorganic & Medicinal Chemistry Letters and is available on the Journal's website. 

The article reported the results of studies conducted by Lorus investigators on the chemical synthesis and in vitro activity of a series of new compounds against multi-drug resistant bacterial strains, including methicillin-resistant Staphylococcus aureus (MRSA). The studies showed that many of these compounds exhibited potent growth inhibition of MRSA strains, based on the low concentrations of compounds required to inhibit bacterial growth. Some of the compounds showed comparable antibacterial activity to that of vancomycin and higher activity than linezoid, both of which are antibiotics currently used to treat serious bacterial infections. 

Additional studies in the article showed that the compound with the most potent activity against MRSA was also active against a range of different Gram-positive bacteria, including strains of vancomycin-resistant enterococci (VRE). Further studies are currently underway to characterize the mode of action of the compounds, and to examine in vivo efficacy of selected compounds in animal models of infection. 

"This publication demonstrates our commitment to identify effective drugs against life-threatening diseases including serious bacterial pathogens, such as MRSA and VRE. There is an urgent need for new treatments for multi-drug resistant bacterial infections, and we plan to fully explore the potential of these promising compounds to be developed as novel antibiotics," said Dr. Aiping Young, Lorus' President and CEO.
