This study evaluated two standardized thyme-derived, carvacrol-based formulations, Vacrol and S-Mix, in lung cancer-associated experimental models. A549 lung adenocarcinoma and BEAS-2B bronchial epithelial cells were treated with the formulations, and cell viability, clonogenic capacity, SIRT1\u2013SIRT7 protein expression, in ovo tumor growth, histopathological changes, and antimicrobial activity against pneumonia-associated reference strains were assessed. S-Mix showed stronger short-term cytotoxicity in A549 cells, reaching an IC50 of 1 mM after 72 h, whereas Vacrol produced more pronounced modulation of selected sirtuin proteins, particularly SIRT1, SIRT4, and SIRT5. Both formulations suppressed colony formation under prolonged exposure. In the CAM model, Vacrol was associated with greater macroscopic suppression of tumor growth and vascularization, while S-Mix produced more prominent histopathological cellular injury. Vacrol also showed antimicrobial activity against tested respiratory pathogens, with MIC values ranging from 0.5 to 4 mg\/mL, MBC values ranging from 1 to 4 mg\/mL and volatile-phase activity against Streptococcus pneumoniae as well as Klebsiella pneumoniae. These findings suggest that carvacrol-based formulations exert distinct cytotoxic, sirtuin-modulatory, antitumoral, and antimicrobial effects, warranting further mechanistic and translational validation.<\/jats:p>","DOI":"10.3390\/antiox15060719","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T07:43:02Z","timestamp":1780904582000},"page":"719","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Carvacrol-Based Formulations Modulate Sirtuins and Exert Cytotoxic and Antimicrobial Effects in Lung Cancer Models"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8618-2682","authenticated-orcid":false,"given":"Selin","family":"Aktar Kiremitci","sequence":"first","affiliation":[{"name":"Pharmaceutical Botany Department, Faculty of Pharmacy, Istinye University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9404-7253","authenticated-orcid":false,"given":"Ay\u015fe Simay","family":"Metin","sequence":"additional","affiliation":[{"name":"Medical Biology and Genetics Doctoral Program, Institute of Graduate Education, Istinye University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8346-2494","authenticated-orcid":false,"given":"\u0130mren","family":"Haso\u011flu","sequence":"additional","affiliation":[{"name":"Medical Biology and Genetics Doctoral Program, Institute of Graduate Education, Istinye University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9575-7801","authenticated-orcid":false,"given":"Mert","family":"Ge\u00e7im","sequence":"additional","affiliation":[{"name":"Department of Biochemistry, Faculty of Pharmacy, Istinye University, 34408 Istanbul, T\u00fcrkiye"},{"name":"Department of Biochemistry, Institute of Health Sciences, Marmara University, 34865 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Didem","family":"Demir","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology, Faculty of Medicine, Istinye University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0905-1977","authenticated-orcid":false,"given":"Emine Hande","family":"Karagedik","sequence":"additional","affiliation":[{"name":"Department of Medical Laboratory Techniques, Vocational School, I\u015f\u0131k University, 34980 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P\u0131nar","family":"Yurdakul Mesuto\u011flu","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology, Faculty of Medicine, Istinye University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3014-1253","authenticated-orcid":false,"given":"\u00d6yk\u00fc","family":"G\u00f6n\u00fcl Geyik","sequence":"additional","affiliation":[{"name":"Medical Biology Department, Faculty of Medicine, Istinye University, 34408 Istanbul, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"ref_1","first-page":"229","article-title":"Global cancer statistics 2022: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"74","author":"Bray","year":"2024","journal-title":"CA Cancer J.
