Taifo Mahmud „Old drugs, new hope: Biosynthetic engineering of new rifamycin and pactamycin analogues“



Natural products continue to play an important role in drug discovery. About two-thirds of recently approved pharmaceuticals are natural product-derived or nature-inspired chemical entities. Despite their importance in medicine, the number of new bioactive natural products identified in recent years has significantly declined. This trend, coupled with the increased threat of multidrug-resistant infectious agents and cancers, calls for new ways of discovering natural product-based medicines. Through a combination of cutting-edge genetic, biosynthetic, and organic synthetic approaches, we have generated many novel analogues of complex natural products. In this presentation, I will discuss our recent progress in creating analogues of two biologically important natural products, the anti-tubercular drug rifamycin and the anti-cancer antibiotic pactamycin.



Dr. Taifo Mahmud received a Ph.D. degree in Pharmaceutical Sciences (Natural Products Chemistry) from Osaka University, under direction of Professor Motomasa Kobayashi in 1997. Subsequently, he received a three-year postdoctoral training from Professor Heinz G. Floss at the University of Washington in Seattle, where he was then promoted to the rank of Research Assistant Professor in Chemistry. In 2003, he joined the Oregon State University College of Pharmacy as an Assistant Professor of Medicinal Chemistry. In 2007, he was promoted to Associate Professor, and in 2013, was promoted to full Professor. Dr. Mahmud’s research interests are in bioorganic chemistry and natural product-based drug discovery and development. His group employs a multidisciplinary approach that utilizes cutting-edge technologies in molecular genetics, enzymology, and chemistry to access, study, utilize, and manipulate genes and enzymes, involved in natural product biosynthesis, to produce novel pharmaceuticals, such as antibiotics, anti-malarial, and anti-cancer drugs.
