Antibacterial and antioxidant activities of Derriobtusone A isolated from Lonch...
Vasconcelos, Mayron Alves; Arruda, Francisco Vassiliepe Sousa; Alencar, Daniel Barroso de; Sampaio, Silvana Saker; Albuquerque, Maria Rose Jane RibeiroThis 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...
Prospecção química da macroalga marinha verde Ulva fasciata Delile
Alencar, Daniel Barroso deMarine macroalgae have been considered promising sources of bioactive compounds. These compounds exhibit different biological properties, such as antibacterial, antifungal, antiviral, anti-inflammatory, antihelminthic, antileshmaniose, antimalaria, antioxidants, and antitumor. Their use as medicine has spurred the interest of many researches. The objective of this work was to carry out a phytochemistry investig...
