Abstract
VILAR CORDEIRO, Laísa et al. Coumarin (2H-1-Benzopyran-2-one) act against planktonic and biofilm forms of Staphylococcus aureus, Klebsiellapneumoniae and Pseudomonas aeruginosa. Rev. colomb. cienc. quim. farm. [online]. 2021, vol.50, n.3, pp.685-694. Epub Dec 18, 2023. ISSN 0034-7418. https://doi.org/10.15446/rcciquifa.v50n3.100226.
Introduction:
biofilm-related infections caused by Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa are difficult to treat and few effective pharmacological options are currently available for this purpose. In this context, coumarin (2H-1-Benzopyran-2-one) has been reported to have antibacterial and antibiofilm activity, but this potential remains poorly understood.
Aim:
to investigate the action of coumarin on planktonic and biofilm forms of S. aureus, K. pneumoniae and P. aeruginosa.
Results:
a minimum inhibitory concentration (MIC) of coumarin ranging from 256 to 1024 fig/mL was observed, with a remarkable ability to inhibit the formation of biofilms and to act on mature biofilms in concentrations close to MIC.
Conclusion:
coumarin has strong activity against planktonic and biofilm forms on the three species of great relevance in the clinical scenario. These results are interesting to enable a pharmacological alternative for the treatment of these infections.
