Many of the most problematic types of resistance originated in the environment, where ancient arms races between antibiotic-producing microbes and their competitors have created vast arsenals of antibiotics and resistance. Seizing on the knowledge that resistance in nature is frequently a harbinger of future clinical resistance, we propose introducing an additional step into the antibiotic development process that exploits the susceptibility of development candidates to environmental resistance as a metric for prioritizing lead compounds and as a roadmap for their structural optimization. Using the antibiotic albicidin as a model, we show how the environmental resistome can guide the development of more resistance-tolerant leads. We used metagenomic surveys to identify resistance vulnerabilities for albicidin and guide the synthesis of analogs that evade the resistance threats. We found that natural albicidin analogs (congeners) were especially enriched in structural features that escape resistance, which inspired our syntheses and provided compelling evidence for the evolution of families of antibiotics in response to resistance in nature. The coupling of metagenomics-based resistance surveillance with structural optimizations of new antibiotics is a broadly applicable approach that is easily integrated into antibiotic development programs to generate compounds that are more resilient in the face of resistance.<\/jats:p>","DOI":"10.1073\/pnas.2504781122","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T15:07:52Z","timestamp":1747667272000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":6,"title":["Environmental resistome\u2013guided development of resistance-tolerant antibiotics"],"prefix":"10.1073","volume":"122","author":[{"given":"James","family":"Peek","sequence":"first","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abir","family":"Bhattacharjee","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e1n","family":"Burian","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David Chun-Cheng","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]},{"name":"Tri-Institutional PhD Program in Chemical Biology, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3349-8856","authenticated-orcid":false,"given":"Yozen","family":"Hernandez","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melinda","family":"Ternei","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Panfil","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5967-8586","authenticated-orcid":false,"given":"Sean F.","family":"Brady","sequence":"additional","affiliation":[{"name":"Laboratory of Genetically Encoded Small Molecules, The Rockefeller University","place":["New York"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature10388"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.mib.2019.06.005"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1220761"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1128\/MMBR.00016-10"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/ismej.2008.86"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.drup.2004.02.003"},{"key":"e_1_3_4_7_2","first-page":"172","article-title":"Molecular characterization of TEM-type beta-lactamases identified in cold-seep sediments of Edison Seamount (south of Lihir Island, Papua New Guinea)","volume":"43","author":"Song J.
