Non-coding RNA: Antibiotic Tricks a Switch

Share

Non-coding RNA: Antibiotic Tricks a SwitchThe golden age of antibiotic discovery, between 1940 and 1960, was heralded by the work of Selman Waksman. A biochemist and microbiologist, Waksman coined the term 'antibiotic' and was the first to use systematic screening to discover antibacterial leads. Efforts in his laboratory yielded more than 20 natural antibiotics — most notably streptomycin in 1943, the first effective treatment for tuberculosis. The discovery won Waksman the 1952 Nobel Prize in Physiology or Medicine. Waksman's research caught the attention of scientists at the US pharmaceutical company Merck, and the ensuing collaboration was instrumental in developing streptomycin for clinical use. On page 672 of [the 29 October 2015 issue of Nature], Howe et al. from the research laboratories of the present Merck describe a new antibiotic lead, identified using a sophisticated refinement of the phenotypic-screening approach introduced by Waksman.

Seven decades after Waksman's research, the flood of antibiotics emerging from natural sources has dwindled to a trickle, and, for various reasons4, few companies remain active in antibiotic drug discovery. This is despite an urgent clinical need for new agents in the face of rising resistance to existing antibiotics. On this background, Howe and colleagues' surprising discovery of a drug target in a bacterial non-coding RNA (ncRNA) provides a welcome bright spot. MORE
