Novel Antibiotic Treatment

Researchers are developing a promising new antibiotic treatment for MRSA and Clostridium difficile infections.

The Glasgow-based company is working on a new compound which has proved to be more effective in killing and preventing C diff. than vancomycin, currently one of the most widely used treatments against this bacterium.

MRSA “Super bug” – Symptoms - Risk Factors – Diagnosis - Treatment
MRSA infection is the most dreaded hospital or community acquired infection that can become life-threatening.

The company has selected the compound, MGB BP-3, as a drug candidate for formal pre-clinical development, with clinical trials now scheduled for 2012.

The compound acts in minor grooves, found within DNA structures, and has potential to act as an agent against bacteria including C. diff. and MRSA.

C. diff. was involved in more than 3,000 deaths in the UK in 2010.

Drug Resistance – Antibiotic or Antimicrobial Resistance
Drug resistance is often a problem in malaria, tuberculosis, HIV, sexually transmitted diseases and hospital acquired diseases. Judicious use of antibiotics can control the problem.

The findings of the research are being presented on Monday, 19 September, at the 51st Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), held in Chicago.

Dr Miroslav Ravic, Chief Executive Officer of MGB Biopharma, said: "It seems we are hearing too much about Clostridium difficile infections these days in the press, especially those acquired in hospital by elderly patients in whom the infection can be fatal.

Coriander Oil may Help Fight Several Bacterial Infections Including MRSA
A new study published in the Journal of Medical Microbiology suggests that coriander oil is very effective in killing a number of bacteria strains

"This is clearly an area of high unmet need as a result of the rise of resistant bacteria which are threatening to outpace the availability of new drugs able to successfully treat these life- threatening infections. We are very excited that MGB BP-3 shows such a promising response against this troublesome and difficult to treat infection.

"We are committed to developing a specific oral drug for the treatment of Clostridium difficile infections in addition to the progress we are making with an IV drug against MRSA."

Bacterial Infections With High Sensitivity and Specificity Detected
A new family of contrast agents that sneak into bacteria disguised as glucose food can detect bacterial infections in animals with high sensitivity and specificity.

Professor Colin Suckling, of the University of Strathclyde's Department of Pure and Applied Chemistry, is Principal Investigator in the DNA minor groove binder technology. He said: "C. diff. infections can kill and patients can face prolonged courses of treatment to deal with them.

"We have come up with strong compounds which are capable not only of clearing the infections but also of stopping them. We believe this could be a significant step forward in tackling these dangerous infections."

Professor Curtis Gemmell, Consultant Microbiologist, Research Professor at the Strathclyde Institute of Pharmacy and Biomedical Sciences and Emeritus Professor at the University of Glasgow, is a senior member of the research team. He said: "The fact that our drug candidate shows greater efficacy than vancomycin is extremely promising for its future. The fact we are making this presentation at ICAAC underscores the importance that our scientific peers attach to our findings."
