Antibacterial and antioxidant activities of Derriobtusone A isolated from Lonch...

This study evaluated the effect of derriobtusone A, a flavonoid isolated from Lonchocarpus obtusus, on two important pathogenic bacteria, Staphylococcus aureus and Escherichia coli, as well as its antioxidant activity and toxicity. Planktonic growth assays were performed, and the inhibition of biofilm formation was evaluated. In addition, antioxidant activity was assessed by DPPH radical scavenging assay, ferro...

Effect of a casbane diterpene isolated from Croton nepetaefolius on the prevent...

This study aimed to evaluate the effect of the compound 1,4-dihydroxy-2E,6E,12E-trien-5-one-casbane (CD1CN), a casbane diterpene isolated from Croton nepetaefolius stalks, on the biofilm formation or preformed biofilms of bacteria and yeasts. Minimum inhibitory concentration results showed that CD1CN inhibited the growth of single cultures of Staphylococcus aureus and Candida albicans at 125 and 500 g/mL, respe...

Casbane diterpene activity on mixed biofilms of P. aeruginosa and Candida species

Prophylactic outcomes of casbane diterpene in Candida albicans and Candida glab...

Biofilms are surface associated communities of microorganisms embedded within a self-produced extracellular matrix and adhered on inert and biotic surfaces. These biological consortia are considered the most prevalent growth form of microorganisms. Biofilm formation is a potent virulence factor for a number of Candida species, as it confers significant tolerance to antimicrobial therapy, primarily by limiting t...

Casbane diterpene as a promising natural antimicrobial agent against biofilm-as...

Croton nepetaefolius is a native plant from northeastern Brazil that belongs to the Euphorbiaceae family. The biological action of this plant has been extensively explored, being the secondary metabolites responsible for its properties alkaloids, diterpenes, and triterpenes. This study aimed to evaluate the ability of casbane diterpene (CD), isolated from the ethanolic extract of C. nepetaefolius, to inhibit mi...
