Its increasing drug resistance drives the search for more effective antifungal agents. Therefore, we assessed toxicological parameters and the antimicrobial activity and mechanisms of action of the monoterpene (-)-fenchone against oral C. albicans. We conducted an in silico study using PASS online and AdmetSAR, followed by evaluation of antifungal activity through Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC), association study with miconazole, and assays with sorbitol and ergosterol. Inhibition of biofilm formation and disruption of preformed biofilm were considered. Toxicity was also assessed through hemolysis assay. The in silico study revealed a higher likelihood of the compound being active for antifungal activity, as well as promising pharmacokinetic and toxicity characteristics. Subsequently, (-)-fenchone exhibited predominantly fungicidal activity (MIC90 = 8 μg/mL; MFC = 16 μg/mL), including against miconazole-resistant C. albicans isolates. The substance does not appear to act by damaging the fungal cell wall or plasma membrane, and exhibited synergy with miconazole. There was activity in inhibiting biofilm formation but not in disrupting preformed biofilm. Finally, the product exerted low hemolytic activity at more than MIC×10. Based on these results, (-)-fenchone may represent a promising therapeutic alternative for oral candidiasis.","PeriodicalId":7776,"journal":{"name":"Anais da Academia Brasileira de Ciencias","volume":"96 4","pages":"e20240273"},"PeriodicalIF":1.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142581832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MMP9 and MMP12 genes were significantly over expressed in group treated with AM. The immunoexpression of MMP9 and MMP12 was observed in all groups. However, the quantitative image analysis demonstrated an increase of the area occupied only by MMP12 in the livers of AM-treated rats with respect to BDL rats.

Considering the decision variables and constraints, flow conservation is a common element observed in intermodal transport mathematical models. Thus, a balance between transportation costs and transportation modes utilization was verified, and insights into the relation between technical logistics factors application and network structures for cargo delivery efficiency were revealed.

Then, to associate mosquito news with the target species, female mosquitoes were captured by a battery-powered aspirator in green areas of the city during September 2019-June 2021. Six mosquito abundance peaks were detected in which Ae. albifasciatus accounted for 97.3% of the captures.
