Chitosan/collagen biomembrane loaded with 2,3-dihydrobenzofuran for the treatme...
Braz, Elton Marks Araujo; Silva, Solranny Carla Cavalcante Costa; Alves, Michel Muálem Moraes; Carvalho, Fernando Aécio Amorim; Magalhães, RuiIn this work, chitosan/collagen-based membranes loaded with 2,3-dihydrobenzofuran (2,3-DHB) were developed through a simple solvent-casting procedure for use in the treatment of cutaneous Leishmaniasis. The obtained membranes were characterized by elemental analysis, FTIR, TG, DSC, and XRD. Porosity, swelling, mechanical properties, hydrophilicity, and antioxidant activity were analyzed. In addition, assessment...

Study of the effect of solvent on acetylate cashew gum-based nanoparticles prop...
Macedo, Karolina Carneiro Morais; Chaves, Luíse Lopes; Vieira, Alexandre Couto Carneiro; Nadvorny, Daniela; Paula, Regina Célia Monteiro deThe aim of this work was to investigate the influence of acetone and dimethyl sulfoxide (DMSO) on acetylated cashew gun (ACG) nanoparticles parameters and to assess their antimicrobial activity. C1 nanoparticles presented smaller size (81.3 nm) than compared to C2 (115.7 nm). Although, acetone formed particles with lower PDI value. Both C1 and C2 presented negative zeta potential (-39.8 and -31.7 respectively)....
Phthalic anhydride esterified chicha gum: characterization and antibacterial ac...
Silva, Solranny Carla Cavalcante Costa; Braz, Elton Marks Araujo; Brito, Carla Adriana Rodrigues Sousa; Alves, Michel Muálem MoraesThe objective of this research was to modify chicha gum with phthalic anhydride to obtain a new biologically active material. The chemical modification of the gum structure was proven through FTIR, elemental analysis, XRD, TG, and DSC. The derived materials demonstrated excellent inhibitory effect against P. aeruginosa and K. pneumoniae species (rating 100% inhibition) and could also inhibit Escherichia coli gr...
Modified chicha gum by acetylation for antimicrobial and antiparasitic applicat...
Braz, Elton Marks Araujo; Silva, Solranny Carla Cavalcante Costa; Brito, Carla Adriana Rodrigues Sousa; Carvalho, Fernando Aécio AmorimIt was developed a material to act as an antimicrobial and antiparasitic agent through a modification reaction in the gum structure extracted from the plant Sterculia striata. This material was characterized, the oxidant activity was evaluated and the antimicrobial activity against Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Salmonella Typhimurium and Klebsiella pneumoniae was investigated, in a...
