Departamento de Micologia. Rio de Janeiro, RJ. Brasil.Universidade Federal Rural do Rio de Janeiro. Instituto de Ciências Exatas. Departamento de Química. Seropédica, RJ, Brasil.We present an efficient procedure for the synthesis of thirty-six N₁,N₄-substituted thiosemicarbazones, including twenty-five ones that are reported for the first time, using a microwave-assisted methodology for the reaction of thiosemicarbazide intermediates with aldehydes in the presence of glacial acetic acid in ethanol and under solvent free conditions. Overall reaction times (20-40 min when ethanol as solvent, and 3 min under solvent free conditions) were much shorter than with the traditional procedure (480 min); satisfactory yields and high-purity compounds were obtained. The thiosemicarbazide intermediates were obtained from alkyl or aryl isothiocyanates and hydrazine hydrate or phenyl hydrazine by stirring at room temperature for 60 min or by microwave irradiation for 30 min, with lower yields for the latter. The preliminary in vitro antifungal activity of thiosemicarbazones was evaluated against Aspergillus parasiticus and Candida albicans.info:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZReis, Camilla Moretto dosPereira, Danilo SousaPaiva, Rojane de OliveiraKneipp, Lucimar FerreiraEchevarria, AureaLICENSElicense.txtlicense.txttext/plain; charset=utf-82991https://arca.fiocruz.br/bitstreams/15865aca-25e0-46b6-bf46-e98915662997/download5a560609d32a3863062d77ff32785d58MD51falseAnonymousREADORIGINALlucimar2_kneipp_etal_IOC_2012.pdflucimar2_kneipp_etal_IOC_2012.pdfapplication/pdf263281https://arca.fiocruz.br/bitstreams/bbaf21aa-10f4-4c3c-9471-76b3b702a143/download11e5c628388c3e838fa559088f35c1c7MD52trueAnonymousREADTEXTlucimar2_kneipp_etal_IOC_2012.pdf.txtlucimar2_kneipp_etal_IOC_2012.pdf.txtExtracted texttext/plain52420https://arca.fiocruz.br/bitstreams/028123e8-fb0b-4016-af50-b25b98c7ad71/downloada565881b60be510156687295441b9006MD59falseAnonymousREADTHUMBNAILlucimar2_kneipp_etal_IOC_2012.pdf.jpglucimar2_kneipp_etal_IOC_2012.pdf.jpgGenerated Thumbnailimage/jpeg34289https://arca.fiocruz.br/bitstreams/00c5d92d-4d5f-48a6-bb32-b7fa37b9b720/download55338aed97699fd3a800b1869fa84761MD510falseAnonymousREADicict/187092025-12-16 06:42:24.715open.accessoai:arca.fiocruz.br:icict/18709https://arca.fiocruz.brRepositório InstitucionalPUBhttps://www.arca.fiocruz.br/oai/requestrepositorio.arca@fiocruz.bropendoar:21352025-12-16T09:42:24Repositório Institucional da FIOCRUZ (ARCA) -
