DB75 [2,5-bis(4-amidinophenyl)furan] is a trypanocidal aromatic diamidine that was originally developed as a structural analogue of the antitrypanosomal agent pentamidine. DB289, a novel orally active prodrug of DB75, is undergoing phase IIb clinical trials for early-stage human African trypanosomiasis,\n            <jats:italic>Pneumocystis jiroveci carinii<\/jats:italic>\n            pneumonia, and malaria. The purpose of this study was to investigate mechanisms of action of DB75 using\n            <jats:italic>Saccharomyces cerevisiae<\/jats:italic>\n            as a model organism. The results of this investigation suggest that DB75 inhibits mitochondrial function. Yeast cells relying upon mitochondrial metabolism for energy production are especially sensitive to DB75. DB75 localizes (by fluorescence) within the mitochondria of living yeast cells and collapses the mitochondrial membrane potential in isolated yeast mitochondria. Furthermore, addition of DB75 to yeast cells or isolated rat liver mitochondria results in immediate uncoupling of oxidative phosphorylation and subsequent inhibition of respiration. We conclude that the mitochondrion is a cellular target of DB75 in yeast cells and anticipate that the results of this study will aid in the target-based design of new antimicrobial aromatic diamidines.\n          <\/jats:p>","DOI":"10.1128\/aac.48.10.3968-3974.2004","type":"journal-article","created":{"date-parts":[[2004,9,23]],"date-time":"2004-09-23T19:02:50Z","timestamp":1095966170000},"page":"3968-3974","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":48,"title":["DB75, a Novel Trypanocidal Agent, Disrupts Mitochondrial Function in\n            <i>Saccharomyces cerevisiae<\/i>"],"prefix":"10.1128","volume":"48","author":[{"given":"Charlotte A.","family":"Lanteri","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernard L.","family":"Trumpower","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Dartmouth Medical School, Hanover, New Hampshire"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard R.","family":"Tidwell","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven R.","family":"Meshnick","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, University of North Carolina, Chapel Hill, Chapel Hill, North Carolina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0014-5793(76)80434-6"},{"key":"e_1_3_2_3_2","first-page":"47","volume":"14","year":"1999","unstructured":"Bailly, C., L.
