Managing invasive fungal infections poses a significant challenge given the limited antifungal options and the emergence of resistance in key fungal pathogens. Through a comprehensive approach, we evaluated the <jats:italic>in vitro<\/jats:italic> antifungal activity and the <jats:italic>in vivo<\/jats:italic> efficacy of two novel lipopeptides, AF<jats:sub>4<\/jats:sub> and AF<jats:sub>5<\/jats:sub> in murine models of disseminated candidiasis, cryptococcosis, and aspergillosis. Flow cytometry analysis with propidium iodide showed a dose\u2010dependent increase in the permeability and disruption of fungal cell membranes, underscoring the membrane perturbing effects of AF<jats:sub>4<\/jats:sub> and AF<jats:sub>5<\/jats:sub>. These observations were further substantiated by SEM analyses that showed yeast cell and hyphal deformation and leakage of cellular contents. Our in vivo investigations utilizing two doses (5 and 10 mg\/kg bodyweight) of each lipopeptide and its comparison with standard antifungal therapies showed lipopeptides significantly improved the odds of mice survival in invasive candidiasis and cryptococcosis models, with a reduction in organ fungal burden by 2 to 3\u2010log<jats:sub>10<\/jats:sub> order. Additionally, in the disseminated aspergillosis model, treatment with 10 mg\/kg of AF<jats:sub>4<\/jats:sub> significantly improved median survival from 4 to 10\u2009days while achieving a notable 1\u2010log10 order reduction in organ fungal burden. Overall, our study underscores the potent and broad\u2010spectrum antifungal activity of lipopeptides in mouse infection models, hinting at their promising therapeutic potential in invasive fungal disease.<\/jats:p>","DOI":"10.1111\/apm.13506","type":"journal-article","created":{"date-parts":[[2024,12,26]],"date-time":"2024-12-26T00:35:11Z","timestamp":1735173311000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Efficacy of two novel antifungal lipopeptides, <scp>AF<sub>4<\/sub><\/scp> and <scp>AF<sub>5<\/sub><\/scp> of bacillomycin D family in murine models of invasive candidiasis, cryptococcosis, and aspergillosis"],"prefix":"10.1111","volume":"133","author":[{"given":"Raees A.","family":"Paul","sequence":"first","affiliation":[{"name":"Department of Medical Microbiology Postgraduate Institute of Medical Education and Research (PGIMER)  Chandigarh India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Madhuri","family":"Madduri","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences BITS Pilani K.K.
