New and Old Hot Drug Targets in Tuberculosis

Curr Med Chem. 2016;23(33):3813-3846. doi: 10.2174/1389557516666160831164925.

Abstract

Tuberculosis is an infectious disease caused by the bacillus Mycobacterium tuberculosis. The World Health Organization publishes global tuberculosis reports annually in order to provide the latest information in the surveillance of drug resistance. Given the alarming rise of resistance to antitubercular drugs worldwide, finding new cellular targets and developing new analogues or new compounds with greater potency against already known targets are both important aspects in fighting drug-sensitive and drug-resistant M. tuberculosis strains. In this context, the introduction of the phenotypic screens as an efficient tool for the identification of active compounds for tuberculosis drug discovery has improved the possibility to find new effective targets. With this review we describe the state of art of the currently well validated antitubercular drug targets as well as the advances in discovery of new ones. The main targets will be discussed starting from the oldest such as the enoyl reductase InhA which is constantly repurposed with new inhibitors, through the well assessed targets like the gyrase, the ATP synthetase or the RNA polymerase, up to the hot promiscuous targets decaprenylphosphoryl-Dribose oxidase DprE1 and the mycolic acid transporter MmpL3, or the newly validated and promising targets like the CTP synthetase.
