Resumo
Objetivo: Reunir e analisar as evidências científicas disponíveis sobre os mecanismos de ação antifúngica de metabólitos produzidos por Streptomyces spp. contra Candida albicans, destacando seu potencial terapêutico frente à resistência antifúngica. Métodos: Trata-se de uma revisão integrativa da literatura, realizada nas bases de dados PubMed, Biblioteca Virtual em Saúde (BVS) e SciELO. A busca contemplou estudos publicados entre 2020 e 2025, utilizando descritores controlados do DeCS/MeSH, combinados pelos operadores booleanos AND e OR. Foram incluídos estudos originais que investigaram compostos bioativos e seus mecanismos antifúngicos, após aplicação de critérios de elegibilidade e leitura na íntegra. Resultados: 11 artigos foram incluídos, os quais demonstraram múltiplos mecanismos de ação, como desorganização da membrana por ligação ao ergosterol, degradação da parede celular por enzimas hidrolíticas, inibição da biossíntese de ergosterol, interferência na N-glicosilação de proteínas, indução de estresse oxidativo e formação de biofilme. Observou-se ainda atividade frente a cepas resistentes e potencial sinergismo com antifúngicos convencionais. Considerações finais: Os achados evidenciam que os Streptomyces spp. constituem uma fonte promissora de agentes antifúngicos com mecanismos diversificados e inovadores, embora sejam necessários estudos pré-clínicos e clínicos para consolidação translacional.
