Using high-throughput microscopy, we monitored olorofim\u2019s antifungal potential at sub-minimum inhibitory concentration (MIC) levels with a focus on early-stage growth. Unlike voriconazole, olorofim showed significant growth inhibitory activities against three main pathogenic\n                      <jats:italic>Aspergillus<\/jats:italic>\n                      species,\n                      <jats:italic>Aspergillus fumigatus<\/jats:italic>\n                      ,\n                      <jats:italic>Aspergillus flavus<\/jats:italic>\n                      , and\n                      <jats:italic>Aspergillus niger<\/jats:italic>\n                      , at concentrations &gt;100,000-fold below its MIC.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>IMPORTANCE<\/jats:title>\n                    <jats:p>\n                      Among antifungal compounds in clinical development for systemic disease, the orotomide olorofim is one of only two that target a completely new mechanism of action. Olorofim is highly potent against pathogenic\n                      <jats:italic>Aspergillus<\/jats:italic>\n                      species including cryptic species that frequently show increased resistance to current agents. In this study, our primary focus was on evaluating in detail the inhibitory activity of voriconazole and olorofim against different pathogenic\n                      <jats:italic>Aspergillus<\/jats:italic>\n                      species employing high-throughput microscopy. Compared to standardized, less-sensitive visual assessment-based methods, microscopy-assisted growth monitoring allowed us to detect sub-MIC drug concentration ranges with significant inhibitory activity at early-stage growth. This revealed that olorofim exerts growth inhibition at concentrations that are several magnitudes below those of voriconazole.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.03304-23","type":"journal-article","created":{"date-parts":[[2024,2,5]],"date-time":"2024-02-05T09:00:51Z","timestamp":1707123651000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":10,"title":["Anti-\n                    <i>Aspergillus<\/i>\n                    activities of olorofim at sub-MIC levels during early-stage growth"],"prefix":"10.1128","volume":"12","author":[{"given":"Alexander","family":"K\u00fchbacher","sequence":"first","affiliation":[{"name":"Institute of Molecular Biology, Biocenter, Medical University of Innsbruck, Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mike","family":"Birch","sequence":"additional","affiliation":[{"name":"F2G Ltd., Manchester, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason D.","family":"Oliver","sequence":"additional","affiliation":[{"name":"F2G Ltd., Manchester, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9257-8648","authenticated-orcid":true,"given":"Fabio","family":"Gsaller","sequence":"additional","affiliation":[{"name":"Institute of Molecular Biology, Biocenter, Medical University of Innsbruck, Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_3_2_2","unstructured":"GAFFI. 2023.
