Evaluation of the antiedematogenic and anti-inflammatory properties of Ximenia americana L. (Olacaceae) bark extract in experimental models of inflammation. Biomed Pharmacother 2023; 166:115249. [PMID: 37597323 DOI: 10.1016/j.biopha.2023.115249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 07/18/2023] [Accepted: 07/27/2023] [Indexed: 08/21/2023] Open
Abstract
Edema is one of the obvious indicators of inflammation and a crucial factor to take into account when assessing a substance's capacity to reduce inflammation. We aimed to evaluate the antiedematogenic and anti-inflammatory profile of the hydroethanolic barks extract of Ximenia americana (HEXA). The possible antiedematogenic and anti-inflammatory effect of EHXA (50, 100 mg/kg and 250 mg/kg v.o) was evaluated using the paw edema induced by carrageenan, zymosan, dextran, CFA and by different agents inflammatory (serotonin, histamine, arachidonic acid and PGE2), and pleurisy model induced by carrageenan and its action on IL-1β and TNF-α levels was also evaluated. HEXA demonstrated a significant antiedematogenic effect at concentrations of 50, 100 and 250 mg/kg on paw edema induced by carrageenan, zymosan and dextran. However, the concentration of 50 mg/kg as standard, demonstrating the effect in the subchronic model, induced CFA with inhibition of 59.06 %. In models of histamine-induced paw edema, HEXA showed inhibition of - 30 min: 40.49 %, 60 min: 44.70 % and 90 min: 48.98 %; serotonin inhibition - 30 min: 57.09 %, 60 min: 66.04 % and 90 min: 61.79 %; arachidonic acid inhibition - 15 min: 36.54 %, 30 min: 51.10 %, 45 min: 50.32 % and 60 min: 76.17 %; and PGE2 inhibition - 15 min: 67.78 %, 30 min: 62.30 %, 45 min: 54.25 % and 60 min: 47.92 %. HEXA significantly reduced (p < 0.01) leukocyte migration in the pleurisy model and reduced TNF-α and IL-1β levels in pleural lavage (p < 0.0001). The results showed that HEXA has the potential to have an antiedematogenic impact in both acute and chronic inflammation processes, with a putative mode of action including the suppression or regulation of inflammatory mediators.

Low-Temperature Vacuum Drying on Broccoli: Enhanced Anti-Inflammatory and Anti-Proliferative Properties Regarding Other Drying Methods. Foods 2023; 12:3311. [PMID: 37685242 PMCID: PMC10486434 DOI: 10.3390/foods12173311] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 08/30/2023] [Accepted: 09/01/2023] [Indexed: 09/10/2023] Open
Abstract
Low-temperature vacuum drying (LTVD) has shown great potential for drying vegetables. It could avoid excessive degradations of active compounds with potential therapeutic agents. In this study, the effect on several relevant bioactive compounds, anti-inflammatory activity, and anti-proliferative activity of broccoli (Brassica oleracea var. italica) were evaluated. Effects of other drying methods, including vacuum drying (VD), convective drying (CD), infrared drying (IRD), and freeze drying (FD), were also comparatively evaluated. The results of all dried samples showed high polyunsaturated fatty acid contents (of up to 71.3%) and essential amino acid contents (of up to 8.63%). The LTVD method stands out above the other drying methods, since it obtained the highest content of total phenols, chlorogenic acid, and ferulic acid. Both the LTVD and CD samples demonstrated high anti-inflammatory and anti-proliferative activities. These CD and LTVD samples were also the most active against the breast carcinoma MDA-MB-23 cell line. Due to the good retention of bioactive compounds via LTVD, the obtained dried broccoli here can be used in a near time as an ingredient for the development of novel natural products with anti-inflammatory and anti-proliferative effects.

Gastroprotective effect of hydroalcoholic extract from Agaricus blazei Murill against ethanol-induced gastric ulcer in mice. JOURNAL OF ETHNOPHARMACOLOGY 2022; 292:115191. [PMID: 35292374 DOI: 10.1016/j.jep.2022.115191] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 02/27/2022] [Accepted: 03/09/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The use of mushrooms in medicine is quite old and the first report about the use of genus Agaricus in treatment of ulcers occurred in Byzantine period. This mushroom is widely consumed as food, tea, food supplements, as well as nutraceutical and cosmeceutical applications, being cultivated and appreciated in several countries such as Brazil, Korea, Japan and China. AIM OF THE STUDY This study aimed to characterize the chemical profile and the potential gastroprotective effect of hydroalcoholic extract from Agaricus blazei Murill (HEAb). MATERIALS AND METHODS The extract was chemically characterized by elemental analysis, UPLC-QTOF-MSE, Nuclear Magnetic Resonance (NMR) and high-performance liquid chromatography (HPLC) techniques to elucidate the metabolites present in the extract. The quantification of phenolic compounds and the in vitro antioxidant activities were performed and the gastroprotective effect of this extract was evaluated against ethanol-induced gastric ulcer model. HEAb was administered by gavage at 5, 25 and 50 mg kg-1 and N-acetylcysteine at 300 mg kg-1 (positive control). Furthermore, the pathways of nitric oxide (NO), Cyclic Guanylate Monophosphate (cGMP), prostaglandins (PGs) and the involvement of ATP-sensitive K+ Channels were modulated. RESULTS Mannitol, malic acid, pyroglutamic acid, L-agaritine and L-valine were putatively identified by UPLC-QTOF-MSE in HEAb. In addition, it was possible to identify mannitol by the intense signals in the NMR spectra, being still quantified as the main compound in the extract by HPLC. The contents of total phenols and flavonoids corroborated with the good antioxidant activity of HEAb. This study observed that HEAb at 25 and 50 mg kg-1 had gastroprotection effect demonstrated by the reduction of histopathological parameters and the reduction of mastocytosis in the stomach of mice. CONCLUSIONS In this study was possible to conclude that HEAb has gastroprotective effect related to the involvement of NO and PG pathways in the ethanol-induced gastric ulcer model in mice.

Abstract
Apremilast (APR) is a selective phosphodiesterase 4 inhibitor administered orally in the treatment of moderate-to-severe plaque psoriasis and active psoriatic arthritis. The low solubility and permeability of this drug hinder its dermal administration. The purpose of this study was to design and characterize an apremilast-loaded microemulsion (APR-ME) as topical therapy for local skin inflammation. Its composition was determined using pseudo-ternary diagrams. Physical, chemical and biopharmaceutical characterization were performed. Stability of this formulation was studied for 90 days. Tolerability of APR-ME was evaluated in healthy volunteers while its anti-inflammatory potential was studied using in vitro and in vivo models. A homogeneous formulation with Newtonian behavior and droplets of nanometric size and spherical shape was obtained. APR-ME released the incorporated drug following a first-order kinetic and facilitated drug retention into the skin, ensuring a local effect. Anti-inflammatory potential was observed for its ability to decrease the production of IL-6 and IL-8 in the in vitro model. This effect was confirmed in the in vivo model histologically by reduction in infiltration of inflammatory cells and immunologically by decrease of inflammatory cytokines IL-8, IL-17A and TNFα. Consequently, these results suggest that this formulation could be used as an attractive topical treatment for skin inflammation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ximenia americana L. is popularly known as yellow plum, brave plum or tallow wood. All the parts of this plant are used in popular medicine. Its reddish and smooth bark are used to treat skin infections, inflammation of the mucous membranes and in the wound healing process. OBJECTIVE Verification of phytochemical profile, the molecular interaction between flavonoid, (-) epi-catechin and 5-LOX enzyme, by means of in silico study, the genotoxic effect and to investigate the pharmacological action of the aqueous extract of the stem bark of X. americana in pulmonary alterations caused by experimental COPD in Rattus norvegicus. MATERIALS AND METHODS The identification of secondary metabolites was carried out by TLC and HPLC chromatographic methods, molecular anchoring tests were applied to analyze the interaction of flavonoid present in the extract with the enzyme involved in pulmonary inflammation process and the genotoxic effect was assessed by comet assay and micronucleus test. For induction of COPD, male rats were distributed in seven groups. The control group was exposed only to ambient air and six were subjected to passive smoke inhalations for 20 min/day for 60 days. One of the groups exposed to cigarette smoke did not receive treatment. The others were treated by inhalation with beclomethasone dipropionate (400 mcg/kg) and aqueous and lyophilized extracts of X. americana (500 mg/kg) separately or in combination for a period of 15 days. The structural and inflammatory pulmonary alterations were evaluated by histological examination. Additional morphometric analyses were performed, including the alveolar diameter and the thickness of the right ventricle wall. RESULTS The results showed that the aqueous extract of the bark of X. americana possesses (-) epi -catechin, in silico studies with 5-LOX indicate that the EpiC ligand showed better affinity parameters than the AracA ligand, which is in accordance with the results obtained in vivo studies. Genotoxity was not observed at the dose tested and the extract was able to stagnate the alveolar enlargement caused by the destruction of the interalveolar septa, attenuation of mucus production and decrease the presence of collagen fibers in the bronchi of animals submitted to cigarette smoke. CONCLUSION Altogether, the results proved that the aqueous extract of X. americana presents itself as a new option of therapeutic approach in the treatment of COPD.

Abstract
OBJECTIVE The objective of this work was evaluate the cytotoxic, leishmanicidal and tripanocidal activity, as well as to evaluate its antimicrobial and modulatory activity in association with different antibiotics of the hydroethanolic extract of the Ximenia Americana stem bark (EHXA). METHOD In vitro tests against Trypanosoma cruzi, Leishmania sp. and citotoxicity were performed. The evaluation of the antibacterial and bacterial resistance modulatory effect was given by the microdilution method. RESULTS The chemical profile show different classes of compounds with significant presence of quercetrin and caffeic acid. The EHXA demonstrated activity only in the concentration of 1000 μg/mL against the L. infantum and L. brasiliensis promastigotes, causing mortality percentage of 40.66 and 27.62%, respectively. The extract presented a significant toxicity only in the concentration of 1000 μg/mL, causing a mortality of 55.42% of fibroblasts. The antibacterial activity of the EHXA demonstrated a MIC value ≥1024 μg/mL against all the tested bacteria. However, in the modulation assay with EHXA in association with different antibiotics the extract had a synergistic effect against S. aureus strains when associated with norfloxacin. CONCLUSION The results of this investigation demonstrate for the first time the chemical composition of the hydroethanolic extract of the Ximenia Americana stem bark, your potential antiparasitic and modulatory effect. The low cytotoxic and biological potential against S. aureus open therapeutic perspectives against leishmaniosis and bacterial infections.

Abstract
Kalanchoe brasiliensis and Kalanchoe pinnata are used interchangeably in traditional medicine in the treatment of wound healing. In this context, the objective of the present study was to evaluate the local anti-inflammatory activity of a topical formulation containing aqueous extract of both species. The in vivo model used was ear edema induced by croton oil and paw edema induced by carrageenan. The Swiss mice treatments use formulations containing aqueous extract at different concentrations (1.25%, 2.5%, and 5%) or dexamethasone (1 mg/g), all administered topically and immediately after edema induction. The treatment with formulations containing aqueous extract of both species reduced ear and paw edema, besides that, the decrease in edema was evidenced by reduction of myeloperoxidase activity, IL-1β, and TNF-α levels and increase IL-10 levels. In conclusion, the two species showed local anti-inflammatory activity; however K. brasiliensis showed a better result in both edematogenic models since it had activity in the lowest concentration.
