Brazilian Green Propolis artepillin C and its acetylated derivative activate the NGF-signaling pathways and induce neurite outgrowth in NGF-deprived PC12 cells
Chem Biodivers. 2023 Nov 12:e202301294. doi: 10.1002/cbdv.202301294. Online ahead of print.ABSTRACTArtepillin C is the most studied compound in Brazilian Green Propolis and, along with its acetylated derivative, displays neurotrophic activity on PC12 cells. Specific inhibitors of the trkA receptor (K252a), PI3K/Akt (LY294002), and MAPK/ERK (U0126) signaling pathways were used to investigate the neurotrophic mechanism. The expression of proteins involved in axonal and synaptic plasticity (GAP-43 and Synapsin I) was assessed by western blotting. Additionally, physicochemical properties, pharmacokinetics, and drug-likeness we...

Antifungal activity and mechanism of action of natural product derivates as potential environmental disinfectants
J Ind Microbiol Biotechnol. 2023 Nov 10:kuad036. doi: 10.1093/jimb/kuad036. Online ahead of print.ABSTRACTThere have been a considerable number of antifungal studies that evaluated natural products, such as medicinal plants, and their secondary metabolites, (phenolic compounds, alkaloids), essential oils, as well as propolis extracts. These studies have investigated natural antifungal substances for use as food preservatives, medicinal agents, or in agriculture as green pesticides because they represent an option of safe, low impact and environmentally friendly antifungal compounds, however, few have studied these natural ...

Molecules, Vol. 28, Pages 7477: The Phenolic Profile and Anti-Inflammatory Effect of Ethanolic Extract of Polish Propolis on Activated Human Gingival Fibroblasts-1 Cell Line
The objective of the conducted study was to assess the anti-inflammatory effects of the Polish ethanolic extract of propolis (EEP) and isolated CAPE on stimulated with LPS and IFN-α, as well as the combination of LPS and IFN-α. The cytotoxicity of the tested compounds was determined using the MTT assay. The concentrations of specific cytokines released by the HGF-1 cell line following treatment with EEP (25–50 µg/mL) or CAPE (25–50 µg/mL) were assessed in the culture supernatant. In the tested concentrations, both CAPE and EEP did not exert...

Red propolis extract as a natural ionophore for confined sheep: performance and morphological and histopathological changes
This study aimed to evaluate the effect of increasing levels of red propolis extract (RPE) in the diet of confined sheep on performance and histomorphometric parameters of rumen and intestine and histopathological parameters of liver and kidney. Thirty-five male sheep (17.08 ± 2.36 kg) were used, distributed in a completely randomized design, with five treatments (0, 7, 14, 21, and 28 mL day-1 RPE) and seven replications, submitted to 68 days of experiment. At the end of the experimental period, the animals were euthanized, and samples of rumen, intestine, liver, and kidney were collected to histomorphometry and histopath...

Leishmanial activity of Brazilian brown propolis and its diterpenes
This study proposes to evaluate the leishmanicidal properties of the hydroalcoholic extract of propolis collected in the southern region of Brazil (Brown propolis - HEBP) and its main isolated compounds: abietic acid (1), 13-epi-cupressic acid (2), 13-epi-torulosol (3), dehydroabietic acid (4), cis-communic acid (5) and ent-agatic acid (6). In general, the diterpenes did not show activity against the promastigotes of Leishmania (Leishmania) amazonensis at the evaluated concentrations. However, the HEBP was very active with an inhibition concentration of 50% at 8.32 µg/mL. Moreover, transmission electron microscopy (TEM) a...

Comparison of cytotoxic and apoptosis-inducing effects of MTA, propolis, and propolis-MTA on immature dental pulp stem cells
ConclusionPropolis-MTA showed higher biocompatibility than MTA. Addition of propolis to MTA improved cell proliferation in the first 24-h. Also, the cytotoxicity of propolis was lower than other materials in the first 24-h. Thus, propolis may serve as a promising pulp capping agent given that its other properties are approved.

Caffeic acid phenethyl ester inhibits MDA-MB-231 cell proliferation in inflammatory microenvironment by suppressing glycolysis and lipid metabolism
Biomed Pharmacother. 2023 Oct 19;168:115766. doi: 10.1016/j.biopha.2023.115766. Online ahead of print.ABSTRACTCaffeic acid phenethyl ester (CAPE) is one of the main active ingredients of propolis with good antitumor activities. However, the potential effects of CAPE on the glycolysis and lipid metabolism of tumor cells are unclear. Here, the anti-tumor effects of CAPE on MDA-MB-231 cells in an inflammatory microenvironment stimulated with lipopolysaccharide (LPS) were studied by estimating the inflammatory mediators and the key factors of glycolysis and lipid metabolism. The CAPE treatment obviously inhibited proliferation...
