    Abstract The aim of this work was evaluate the effects of terpinolene on acute inflammatory responses in mice. In vivo preclinical research using different inflammatory agents to induce acute responses and evaluate the effects of terpinolene in orally treated mice. The acute inflammatory responses were induced by injecting phlogistic agents in the mice paw to observe the development of pain responses (formalin test) or edema (carrageenan, dextran, histamine, arachidonic acid, and prostaglandin). The antiedematogenic activity was also evaluated using a croton oil-induced ear edema model. Finally, cotton pellet-induced granuloma was used to carry out a preliminary evaluation of terpinolene in a chronic inflammatory model. Topically administered terpinolene (5, 10, and 20 mg/mL) significantly inhibited ear edema development (by 33.82%, 29.63%, and 33,30%, respectively). Following an oral administration, only the highest dose of the monoterpene (200 mg/kg) reduced the licking time of the formalin test in both phases 1 (73.55%) and 2 (96.61%). The carrageenan-induced edema significantly inhibited over time following the oral administration of terpinolene at 50 mg/kg (T1: 47.74%, T2: 54.67%, T3: 48.63%, and T4: 62.99%), 100 mg/kg (T1: 72.86%, T2: 71.03%, T3: 48.63%, and T4: 57.83%), and 200 mg/kg (T1: 43.22%, T2: 34.11%, T3: 36.47%, and T4: 45.20%). On the other hand, only the dose of 200 mg/kg) caused a significant reduction of the dextran-induced paw edema (T1: 51.18%, T2: 60%, T3: 50.92%, and T4: 65.15%). Regarding the participation of inflammatory pathways, the monoterpene (200 mg/kg, p.o.) had little impact on histamine-induced edema, while the edema induced by arachidonic acid was significantly reduced at all time-points (T1: 37.04%, T2: 24.32%, and T3: 35.13%, and T4: 35.53%), which was corroborated by the observation that the compound inhibited the response triggered by prostaglandin E₂ (PGE₂), suggesting interference with downstream signaling cascades. Finally, terpinolene (200 mg/kg, p.o.) reduced both the weight (21.43%) and total protein content (36.21%) of the cotton pellet-induced granuloma, indicating an anti-inflammatory activity in this chronic model. Terpinolene inhibited acute inflammatory responses and reduced granuloma development in vivo, possibly by interfering with the tissue changes orchestrated by inflammatory mediators such as histamine and PGE₂. However, the molecular mechanisms underlying this pharmacological observation need to be confirmed by further research.

    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 PGE

    Abstract Products of natural origin remain important in the discovery of new bioactive molecules and are less damaging to the environment. Benzaldehyde is a product of the metabolism of plants, and similarly to oxygenated terpenes, it can have antibacterial activity against Staphylococcus aureus and toxic action against Drosophila melanogaster

    we aimed to verify these activities. The broth microdilution tests determined the minimum inhibitory concentration (MIC) of benzaldehyde alone and in association with antibiotics and ethidium bromide (EtBr). Toxicity against Drosophila melanogaster was determined by fumigation tests that measured lethality and damage to the locomotor system. The results indicated that there was an association of norfloxacin and ciprofloxacin with benzaldehyde, from 64 μg/mL to 32 μg/mL of ciprofloxacin in the strain K6028 and from 256 μg/mL to 128 μg/mL of norfloxacin in the strain 1199B; however, the associations were not able to interfere with the functioning of the tested efflux pumps. In addition, benzaldehyde had a toxic effect on flies. Thus, the results proved the ability of benzaldehyde to modulate quinolone antibiotics and its toxic effects on fruit flies, thus enabling further studies in this area.

    Abstract Background: Terpinolene, a monoterpene that is naturally found in a variety of herbs, is widely used as a flavoring agent in the industry. Although it's well established in the literature that terpinolene is an important component of plant extracts, the biological properties and the potential therapeutic use of this compound remain poorly explored.
    Purpose: This work aimed to answer the following guiding question: "What are the biological activities of terpinolene demonstrated through in silico, in vitro, and in vivo assays?".
    Study design and methodology: A systematic review was carried out in four electronic databases (Embase, Web of Science, Scopus, and PubMed) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, using the following search terms: terpinolene "AND" activity "OR" properties "OR" therapeutic "OR" treatment. This search included manuscripts published between 1960 and June 2020. Study selection was conducted by two independent reviewers according to predefined criteria.
    Results: The initial search found a total of 2449 articles. However, only 57 of them were selected as they met the inclusion criteria and answered the guiding question. The analysis of these studies indicated that terpinolene presents a series of biological effects, from which the antioxidant, larvicide, and insecticide activities stand out. Despite the evidence demonstrating that terpinolene has the potential to be used in a broad pharmacological context, the mechanisms underlying its cellular and molecular effects remain to be better elucidated. In addition, the in vivo efficacy and safety of the administration of this compound have been poorly evaluated through either preclinical and clinical trials. Therefore, this study highlights the importance of characterizing the biological aspects and mechanisms of action of this natural compound.
    Conclusion: The data summarized in the present systematic review demonstrates the pharmacological potential of terpinolene. Nevertheless, most studies included in this review provide a superficial characterization of terpinolene biological effects and therefore, further research elucidating its mechanism of action and potential therapeutic benefits through preclinical and clinical trials are required. Nevertheless, due to its wide range of different biological activities, terpinolene will certainly attract the interest of scientific research, which could significantly contribute to the development of new products with both therapeutic and environmental applications.

    Abstract Ximenia americana L., popularly known in Brazil as “ameixa do-mato, ameixa-brava, and ameixa-do-sertão,” is widely used in folk medicine to treat several intestinal disorders. The present study assessed the potential mechanisms of action underlying the gastroprotective activity of the hydroethanolic extract of Ximenia americana L. (EHXA) stem bark. The acute toxicity of EHXA was estimated, and later, the gastroprotective effect in mice was assessed through acute models of gastric lesions induced by acidified or absolute ethanol and indomethacin, where the following mechanisms were pharmacologically analyzed: the involvement of prostaglandins (PG), histamine (H 2 ) receptors, ATP-dependent potassium channels, sulfhydryl groups (SH), α 2 adrenergic receptors, nitric oxide (NO), myeloperoxidase (MPO), gastric mucus production, and acetylcholine-mediated intestinal motility. Regarding toxicity, EHXA did not cause deaths or signs of toxicity (LD 50 greater than or equal to 2000 mg/kg/p.o.). When the gastroprotective effect was assessed, EHXA (50, 100, and 200 mg/kg/p.o.) reduced the rate of lesions induced by acidified ethanol by 65.63; 53.66, and 58.02% in absolute ethanol at 88.91, 78.82, and 74.68%, respectively, when compared to the negative control group. In the indomethacin-induced gastric injury model, the reductions were 84.69, 55.99, 55.99, and 42.50%, respectively. The study revealed that EHXA might stimulate mucus production and reduce intestinal motility through SH groups, NO production, and activation of α 2 adrenergic receptors. The results indicated that EHXA had significant gastroprotective activity in the evaluated models. However, further investigation is required to elucidate the cellular and molecular events underlying the action of EHXA components and to correlate them with the modulation of the signaling pathways, as demonstrated by the current pharmacological approach. Therefore, the results demonstrated in the present study, as well as previously reported findings, support the recommendation ...

The principle of the 3R’s (replacement, reduction and refinement) has been an important reference, such that in vitro, ex vivo and cord replacement methods have achieved a prominent place in research. Methods: Therefore, due to successful results from studies developed with these methods, the present study aimed to evaluate the myorelaxant effect of the Dysphania ambrosioides essential oil (EODa) using a Sus scrofa domesticus coronary artery model, and the toxicity of both the Dysphania ambrosioides essential oil and its major constituent, α-terpinene, against Drosophila melanogaster in toxicity and negative geotaxis assays. Results: The EODa relaxed the smooth muscle of swine coronary arteries precontracted with K + and 5-HT in assays using Sus scrofa domesticus coronary arteries. The toxicity results presented LC 50 values of 1.546 mg/mL and 2.282 mg/mL for the EODa and α-terpinene, respectively, thus showing the EODa and α-terpinene presented toxicity to these dipterans, with the EODa being more toxic. Conclusions: Moreover, the results reveal the possibility of using the EODa in vascular disease studies since it promoted the relaxation of the Sus scrofa domesticus coronary smooth muscle.
