Abstract
Immune response to biomaterials, which is intimately related to their surface properties, can produce chronic inflammation and fibrosis, leading to implant failure. This study investigated the development of magnetic nanoparticles coated with silica and incorporating the anti-inflammatory drug naproxen, aimed at multifunctional biomedical applications. The synthesized nanoparticles were characterized using various techniques that confirmed the presence of magnetite and the formation of a silica-rich bioactive glass (BG) layer. In vitro studies demonstrated that the nanoparticles exhibited bioactive properties, forming an apatite surface layer when immersed in simulated body fluid, and biocompatibility with bone cells, with good viability and alkaline phosphatase activity. Naproxen, either free or encapsulated, reduced nitric oxide production, an inflammatory marker, while the BG coating alone did not show anti-inflammatory effects in this study. Overall, the magnetic nanoparticles coated with BG and naproxen showed promise for biomedical applications, especially anti-inflammatory activity in macrophages and in the bone field, due to their biocompatibility, bioactivity, and osteogenic potential.

Abstract
Chagas disease (CD) is a worldwide public health problem, and the drugs available for its treatment have severe limitations. Red propolis is a natural extract known for its high content of phenolic compounds and for having activity against T. cruzi. The aim of this study was to investigate the trypanocidal potential of red propolis to isolate, identify, and indicate the mode of action of the bioactive compounds. The results revealed that the total phenolic content was 15.4 mg GAE/g, and flavonoids were 7.2 mg QE/g. The extract was fractionated through liquid-liquid partitioning, and the trypanocidal potential of the samples was evaluated using the epimastigote forms of the Y strain of T. cruzi. In this process, one compound was characterized by MS, 1H, and 13C NMR and identified as vestitol. Cytotoxicity was evaluated employing MRC-5 fibroblasts and H9C2 cardiomyocytes, showing cytotoxic concentrations above 15.62 μg/mL and 31.25 μg/mL, respectively. In silico analyses were applied, and the data suggested that the substance had a membrane-permeation-enhancing effect, which was confirmed through an in vitro assay. Finally, a molecular docking analysis revealed a higher affinity of vestitol with farnesyl diphosphate synthase (FPPS). The identified isoflavan appears to be a promising lead compound for further development to treat Chagas disease.

Abstract
Many activities have been described for propolis, including, antiviral, antibacterial, antifungal, anti-inflammatory, immunoregulatory, antioxidant and wound healing properties. Recently, propolis has been highlighted due to its potential application in the pharmaceutical and cosmetic industries, motivating a better understanding of its antioxidant and anti-inflammatory activities. Propolis and its main polyphenolic compounds presented high antioxidant activity, and effectiveness as broad spectrum UVB and UVA photoprotection sunscreens. Through a qualitative phytochemical screening, the ethanolic red propolis extracts (EEPV) (70% at room temperature and 70% at a hot temperature) presented a positive result for flavonoids and terpenoids. It presented an antioxidant activity for reducing 50% of DPPH of 17 and 12 μg/mL for extraction at room temperature and at a hot temperature, respectively. The UPLC-QTOF-MS/MS analysis allowed the annotation of 40 substances for EEPV-Heated and 42 substances for EEPV-Room Temperature. The IC50 results of the ABTS scavenging activity was 4.7 μg/mL for both extractions, at room temperature and at a hot temperature. Additionally, we also evaluated the cytotoxic profile of propolis extracts against macrophage (RAW 264.7 cells) and keratinocytes (HaCaT cells), which showed non-cytotoxic doses in cell viability assays even after a long period of exposure. In addition, propolis extracts showed antibacterial activity for Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis), demonstrating potential biological activity for the creation of formulations aimed at disease control and prevention.

Abstract
Modified release systems depend on the selection of an appropriate agent capable of controlling the release of the drug, sustaining the therapeutic action over time, and/or releasing the drug at the level of a particular tissue or target organ. Polyethylene glycol 4000 (PEG 4000) is commonly employed in drug release formulations while polymethyl methacrylate (PMMA) is non-toxic and has a good solubility in organic solvents. This study aimed at the incorporation of ketoconazole in PMMA-g-PEG 4000 and its derivatives, thus evaluating its release profile and anti-Candida albicans and cytotoxic activities. Ketoconazole was characterized and incorporated into the copolymers. The ketoconazole incorporated in the copolymer and its derivatives showed an immediate release profile. All copolymers with ketoconazole showed activity against Candida albicans and were non-toxic to human cells in the entire concentration tested.

Abstract
Resumo O rápido desenvolvimento da química de polímeros nos últimos anos tem acompanhado a introdução dos materiais poliméricos no campo da medicina. Polímeros com aplicações médicas podem ser subdivididos em dois grandes grupos: materiais usados em próteses e a produção de polímeros biologicamente ativos. Neste trabalho foram sintetizados copolímeros possuindo cadeia principal de poli (metacrilato de metila) e cadeias enxertadas de polietilenoglicol (COP GRAFT). A partir da síntese do copolímero enxertado inicial foram realizadas modificações em suas cadeias de modo a aumentar a possibilidade de incorporação de um fármaco que será utilizado em sistema de liberação controlada de medicamentos. Os novos compostos foram obtidos através de duas rotas sintéticas e os produtos formados ao final de cada etapa foram purificados e caracterizados. Através da técnica de infravermelho (FITIR) foi possível observar as bandas de absorções características das ligações P-H, P=O e P-O, que foram inseridas na cadeia do COP GRAFT durante a fosforilação, além das bandas de absorções características do copolímero, antes da fosforilação, como C=O e C-O. A caracterização térmica das amostras utilizando termogravimetria (TGA) e calorimetria diferencial de varredura (DSC) mostrou que apenas o copolímero de diisobutila apresentou temperatura de transição endotérmica e comportamentos de degradação compatíveis a de um polímero. Através da técnica de difração de raios X (XRD) foi possível observar uma modificação da cristalinidade das amostras, provavelmente devido a uma variação da conformação das cadeias após a inserção de novos grupos químicos. Nos cromatogramas obtidos pela técnica de cromatografia de permeação em gel (GPC) percebeu-se aumento de massa após a fosforilação com o grupo diisobutila no COPGRAFT. A reação de fosforilação foi eficiente na obtenção do copolímero de diisobutila e as técnicas aplicadas demonstraram que houve a modificação no copolímero enxertado.
