Researchers seek new TB treatments
The University of Illinois at Chicago will work with TB Alliance to help find new drug treatments for tuberculosis, a bacterial infection considered to be one of the leading causes of death worldwide. TB Alliance is a nonprofit organization dedicated to the discovery, development and delivery of new TB cures.
The goal is to produce two new clinical-stage drug candidates for treating tuberculosis, which is becoming increasingly resistant to available antibiotics.
The five-year research project will receive up to $28.4 million in funding through the National Institute of Allergy and Infectious Diseases-supported Centers of Excellence for Translational Research program (U19AI142735-01). UIC will be one of three key partners to TB Alliance, the primary recipient of the grant.
As part of the project, UIC and its Institute for Tuberculosis Research will receive up to $9 million in funding to investigate promising natural compounds and their effect against TB and to evaluate the treatment potential of compounds developed by researchers from Harvard University and Johns Hopkins University, the other key partners on the project.
UIC, Harvard and Johns Hopkins will investigate compounds that work on different molecular targets that are essential for the survival of the causative agent of TB, Mycobacterium tuberculosis. UIC will focus on compounds that target the ClpC1 protein, which assists in degrading proteins within the bacterium.
The UIC research team includes Sanghyun Cho, research associate professor of medicinal chemistry and pharmacognosy; Scott Franzblau, the Albert Schatz Professor in the Department of Medicinal Chemistry and Pharmacognosy; and Guido Pauli, the Norman R. Farnsworth Professor of Pharmacognosy.
“Our institute has been building specialized laboratory assays for investigating TB for many years,” said Franzblau, who is also director of the Institute for Tuberculosis Research, which is part of UIC’s College of Pharmacy. “These assays will allow us to evaluate potential drug compounds against M. tuberculosis in both in vitro and in vivo environments, and the combined efforts of all the partner institutions involved in this project will increase the chances of finding new drug candidates, which we need urgently.”
Among the challenges of treating tuberculosis is the bacterium’s ability to develop resistance to current drugs. Treatment can include all four of the first-line drugs, which are taken over the course of six months, Franzblau said.
“Because TB treatment can take a long time, it is common for patients to become non-adherent, which also increases their likelihood of developing resistance to the medication,” Franzblau said. “Ideally, we need drugs that can eradicate the infection in several weeks.”
Also working on the project are researchers from Princeton University, Texas A&M University, Myongji University and Eli Lilly.
