"It" is Mycobacterium tuberculosis.

A Kansas State University chemistry professor is seeking to stem the tide in the war against TB. According to the WHO, no new antituberculosis drugs have been marketed during the last 30 years. As such, new strategies are needed to lead to the successful development of antituberculosis therapies.

K-State's Stefan H. Bossmann is researching a new strategy for treatment of the deadly infectious disease using ruthenium-polypyridyl-complexes as antimycobacterial drugs.

Bossmann's research explores unique physical and chemical properties of channel proteins called porins, isolated from Mycobacterium smegmatis and Mycobacterium tuberculosis. He is attempting to understand the working principles of porin channels in natural and artificial environments and he hopes to eventually develop supramolecular model systems to serve as physical models for the biological function of the porin systems.

Bossmann will discuss his research at the American Chemical Society's national meeting and exposition, Aug. 28 - Sept. 1, in Washington, D.C. He will give an oral presentation at the conference Tuesday, Aug. 30.

"We have more and more resistant strains developing in Asia and Russia. We're also getting a large number of patients infected with TB immigrating to the United States," Bossmann said.

According to Bossmann, not many antibiotics actually work in treating TB because the disease has been steadily developing resistance to them. This makes new strategies for the delivery of drugs urgently needed, he said.

"It will become extremely difficult to treat cases of TB, in say 10 to 20 years down the road, because new treat
