Extract Enhances Mupirocin Activity When Combined with Nanoemulsion-Based Hydrogel: A Multi-Target Strategy for Treating Skin and Soft Tissue Infections.

The treatment of skin and soft tissue infections (SSTIs) can be challenging due to bacterial resistance, particularly from strains like MRSA and biofilm formation. However, combining conventional antibiotics with natural products shows promise in treating SSTIs. The objective of this study is to develop a nanoemulsion-based hydrogel containing extract and mupirocin and evaluate its potential for the treatment of SSTIs.

Identification, characterization and quantification of xanthones from Fridericia formosa leaves extract with antiviral activity.

Fridericia formosa (Bureau) L.G. Lohmann (Bignonaceae) is a neotropical liana species found in the Cerrado biome in Brazil.

Anti- Potential of Vestitol Isolated from Lyophilized Red Propolis.

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 . 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.

Evaluation of Anti- Activity and Release of Ketoconazole in PMMA-G-PEG 4000 Films.

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- and cytotoxic activities.

Modulation of Long Non-coding RNAs by Different Classes of Secondary Metabolites from Plants: A Mini-review on Antitumor Effects.

The broad pharmacological spectrum of plants is related to their secondary metabolism, which is responsible for the synthesis of different compounds that have multiple effects on cellular physiology. Among the biological effects presented by phytochemicals, their use for the prevention and treatment of cancer can be highlighted. This occurs due to several mechanisms of antitumor action demonstrated by these compounds, including regulation of the cell signaling pathways and inhibition of tumor growth.

Brazilian essential oils as source for the discovery of new anti-COVID-19 drug: a review guided by in silico study.

Unlabelled: The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China and its spread worldwide has become one of the biggest health problem due to the lack of knowledge about an effective chemotherapy. Based on the current reality of the SARS-CoV-2 pandemic, this study aimed to make a review literature about potential anti-coronavirus natural compounds guided by an in silico study. In the first step, essential oils from native species found in the Brazilian herbal medicine market and Brazilian species that have already shown antiviral potential were used as source for the literature search and compounds selection.

Cytotoxic activity of butanolic extract from L. flowers and vehiculated in micelles in bladder cancer cells and fibroblasts.

Bladder cancer has a high incidence and recurrence rate among patients worldwide. This study aimed to evaluate the cytotoxic activity of fractions of L. flower extracts on bladder carcinoma cells (T24 cells) and human fibroblast cells (MRC-5).

Antitumor effect of (Linneu) essential oil in bladder cancer cells.

The aim of this study was to analyse the antitumor effect of the essential oil and on bladder cancer cells RT4 and T24, with different status. The oil was extracted by hydrodistillation and the gas chromatography coupled to the mass spectrometry was used for characterisation. analysis was carried out by Pass online software.

Herbal medicines to the treatment of skin and soft tissue infections: advantages of the multi-targets action.

The research for new treatments of skin and soft tissue infections (SSTIs) is important due to their high prevalence and number of hospitalizations. The purpose of this review is to address the pathophysiology of SSTIs to highlight the advantages of herbal medicines to their treatment, showing examples of species and compounds with multi-targets action. SSTIs have a complex physiopathology involving the microorganism, as well as inflammation and difficult healing.

Anti-inflammatory activity of Protium spruceanum (Benth.) Engler is associated to immunomodulation and enzymes inhibition.

Aims Of The Study: analyze the aspects involved in the anti-inflammatory activity of polar fractions obtained from extracts of leaves and branches.

Materials And Methods: Hydromethanolic fraction was obtained by liquid-liquid partition from crude ethanolic extract and its compounds were identified by LC-DAD-MS.

Development of propolis nanoemulsion with antioxidant and antimicrobial activity for use as a potential natural preservative.

Propolis has demonstrated potential use as food preservative but it presents strong and unpleasant flavor that alters the sensory characteristics foods. A nanoemulsion was proposed to carry the Brazilian propolis extracts for use as natural food preservative. Antimicrobial and antioxidant activities and chemical constituents of the extracts were investigated.

Antibacterial activity of extract and fractions from branches of Protium spruceanum and cytotoxicity on fibroblasts.

The crude ethanol extract (CEE) and fractions from branches of Protium spruceanum were subjected to antibacterial and cytotoxicity assays.
