Abstract
Xanthine oxidase (XO) has been widely recognized as a pivotal enzyme in developing hyperuricemia, primarily contributing to the excessive production of uric acid during purine metabolism in the liver. One of the standard treatment approaches involves reducing uric acid levels by inhibiting XO activity. In this study, the leaf extract of Dolichandrone spathacea, traditionally used in folk medicine, was found to inhibit XO activity in the ethyl acetate and butanol fractions at a concentration of 100 µg/mL, their values were 78.57 ± 3.85 % (IC50 = 55.93 ± 5.73 µg/ml) and 69.43 ± 8.68 % (IC50 = 70.17 ± 7.98 µg/ml), respectively. The potential XO inhibitory components were isolated by bioactivity assays and the HR-ESI-MS and NMR spectra system. The main constituents of leaf extracts of Dolichandrone spathacea, six compounds, namely trans-4-methoxycinnamic acid (3), trans-3,4-dimethoxycinnamic acid (4), p-coumaric acid (5), martynoside (6), 6-O-(p-methoxy-E-cinnamoyl)-ajugol (7), and scolymoside (17), were identified as potent XO inhibitors with IC50 values ranging from 19.34 ± 1.63 μM to 64.50 ± 0.94 μM. The enzyme kinetics indicated that compounds 3-5, 7, and 17 displayed competitive inhibition like allopurinol, while compound 6 displayed a mixed-type inhibition. Computational studies corroborated these experimental results, highlighting the interactions between potential metabolites and XO enzyme. The hydrogen bonds played crucial roles in the binding interaction, especially, scolymoside (17) forms a hydrogen bond with Mos3004, exhibited the lowest binding energy (-18.3286 kcal/mol) corresponding to the lowest IC50 (19.34 ± 1.63 μM). Furthermore, nine compounds were isolated for the first time from this plant. In conclusion, Dolichandrone spathacea and its constituents possess the potential to modulate the xanthine oxidase enzyme involved in metabolism.

Abstract
Metabolic syndrome (MetS) predisposes individuals to chronic non-communicable diseases (NCDs) like type 2 diabetes (T2D), non-alcoholic fatty liver disease, atherosclerosis, and cardiovascular disorders caused by systemic inflammation, intestinal dysbiosis, and diminished antioxidant ability, leading to oxidative stress and compromised insulin sensitivity across vital organs. NCDs present a global health challenge characterized by lengthy and costly pharmacological treatments. Complementary and alternative medicine using herbal therapies has gained popularity. Approximately 350,000 plant species are considered medicinal, with 80% of the world's population opting for traditional remedies; however, only 21,000 plants are scientifically confirmed by the WHO. The Rubiaceae family is promissory for preventing and treating MetS and associated NCDs due to its rich content of metabolites renowned for their antioxidative, anti-inflammatory, and metabolic regulatory properties. These compounds influence transcription factors and mitigate chronic low-grade inflammation, liver lipotoxicity, oxidative stress, and insulin resistance, making them a cost-effective non-pharmacological approach for MetS prevention and treatment. This review aims to collect and update data that validate the traditional uses of the Rubiaceae family for treating MetS and associated NCDs from experimental models and human subjects, highlighting the mechanisms through which their extracts and metabolites modulate glucose and lipid metabolism at the molecular, biochemical, and physiological levels.

Alibertia patinoi (Cuatrec.) Delprete & C.H.Perss. (Borojó): food safety, phytochemicals, and aphrodisiac potential. SN APPLIED SCIENCES 2023.

Abstract
AbstractAlthough the western discovery of borojó [Alibertia patinoi Cuatrec. (Delprete & C.H.Perss.)] is as recent as 1948, its several traditional uses in gastronomy and medicine, and its fame as an aphrodisiac are long standing and strong: the “love juice” extracted from it is very appreciated in Colombia, Ecuador, and Panama. Its medicinal potential, though, is far wider. This literature review aims to summarize the knowledge about the fruit, its ethnomedical uses, its biological activity and phytochemical composition, to validate ethnomedical claims and to help envision future lines of research. Borojó extracts have confirmed antimicrobial and antioxidant, and potential anticancer activities, which can be at least partially explained by its phytochemical composition -compounds isolated and identified through Gas Chromatography, High Performance Liquid Chromatography and spectroscopic and spectrometric techniques- rich in phenolic compounds, some of which, for example oleuropein, chlorogenic acid and rutin, possess proven biological activity. There is potential for borojó products as a source of bioactive natural products, which have not been exhaustively identified despite phytochemical screenings that show the presence of unstudied compound families: terpenoids, alkaloids, steroids; and functional alimentary products. Although its aphrodisiac properties have not been confirmed, several compounds with confirmed aphrodisiac activity in other species, mainly flavonoids, are also found in borojó. These, coupled with its nutritional profile and perhaps compounds yet unidentified, could validate the claim.

Abstract
Medicinal plants are used in traditional medicine to treat a wide range of ailments. The knowledge of them is handed down from generation to generation and is described in several pharmacopoeia and in the general literature. The immense biodiversity of the Brazilian flora, covering about 25% of all plant species worldwide, makes Brazil a huge potential source of medicinal plants. Indeed, many of these plant species are already used in the Brazilian ethnopharmacology for their probable effect to induce diuresis, to reduce fluid retention, and to treat cardiovascular and renal disorders. This review article describes and discusses the main native Brazilian medicinal plants (including some of their isolated compounds) used as diuretics. It also gives a comprehensive analysis of the most relevant scientific studies presented to date, as well as addressing a special topic with future prospects for plant species that have not yet been scientifically studied. In brief, several plants can be indicated for more detailed study, with a view to obtain scientific subsidies for a new and effective diuretic medicine in the future. These include Bauhinia forficata, Leandra dasytricha, and Tropaeolum majus. Other species have reputed medicinal properties but lack experimental assays to demonstrate their pharmacological effects (e.g., Mikania hirsutissima, Phyllanthus niruri, and Tagetes minuta). Several active principles are indicated as responsible for the diuretic effects of the plants studied, with emphasis on phenolic compounds as flavonoids, phenolic acids, and xanthones. These results should encourage more detailed preclinical, clinical, and phytochemical investigations on Brazilian plants in the future.

Abstract
Alibertia edulis leaf extract is commonly used in folk medicine, with rutin caffeic and vanillic acids being its major compounds. The Alibertia edulis leaf extract was investigated for its pharmacological effects via platelet aggregation, calcium mobilization, cyclic nucleotides levels, vasodilator-stimulated phosphoprotein Ser157 and Ser239 and protein kinase Cβ2 phosphorylation, thromboxane B2, cyclooxygenases 1 and 2, docking and molecular dynamics. Alibertia edulis leaf extract significantly inhibited (100-1000 μg mL-1) platelet aggregation induced by different agonists. Arachidonic acid increased levels of calcium and thromboxane B2, phosphorylation of vasodilator-stimulated phosphoprotein Ser157 and Ser239, and protein kinase Cβ, which were significantly reduced by Alibertia edulis leaf extract, rutin, and caffeic acid as well mixtures of rutin/caffeic acid. Cyclooxygenase 1 activity was inhibited for Alibertia edulis leaf extract, rutin and caffeic acid. These inhibitions were firsrtly explored by specific stabilization of rutin and caffeic acid compared to diclofenac at the catalytic site from docking score and free-energy dissociation profiles. Then, simulations detailed the rutin interactions close to the heme group and Tyr385, responsible for catalyzing the conversion of arachidonic acid to its products. Our results reveal the antiplatelet aggregation properties of Alibertia edulis leaf extract, rutin and caffeic acid providing pharmacological information about its origin from cyclooxygenase 1 inhibition and its downstream pathway.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Alibertia edulis (L.C. Rich.) A.C. Rich is a vegetable species used in Brazilian folk medicine due to it is putative hypoglycemiant effect but has never been pharmacologically investigated. It is popularly used for the control of diabetes, especially in the state of Mato Grosso, Brazil. Following confirmation of the antioxidant activity of A. edulis by Aquino et al. (2017), the aim of this study was to evaluate the effects of leaves of A. edulis aqueous extract (AEAE) on some biochemical parameters in mice fed a high-fat fed. MATERIAL AND METHODS Leaves of A. edulis were air-dried in an oven at 40 °C for 10 days and ground into a fine powder by mechanical milling. The AEAE was prepared by decoction (1:10 w/v) at 97 °C for 15 min, and later filtered and lyophilized. Preliminary phytochemical analysis of the AEAE has been already indetified the presence of caffeic acid, quercetin 3-rhamnosyl-(1 → 6)-galactoside and iridois ioxide, ferulic acid and rutin in decocted leaves (Aquino et al., 2017). In one experiment, the acute oral toxicity AEAE was evaluated at 2,000 mg/kg of body weight. The animals were observed periodically for 14 days. In second experiment, the animals were divided into four groups (n = 5): Control, AEAE 200, AEAE 400 mg/kg and positive control (Metformin 100 mg/kg). In a third experiment, animals were divided into: Control RC (standard diet) (n = 24) and Control HFF (high-fat fed) (n = 24) groups for induction of glucose intolerance. After eight weeks, they were further subdivided into six groups (n = 8 each) RC or HFF with or without AEAE at doses of 200 and 400 mg/kg (2-wk) treatments to assess glucose tolerance. Plasma indicators of glucose tolerance and liver damage, skeletal muscle expression of antioxidant enzymes, and expression of the antioxidant proteins of superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx) and phosphorylated IKK were determined. RESULTS The HF-fed animals developed glucose intolerance which the AEAE failed to revert. Meanwhile, the AEAE treatment did lower the glucose levels in the normolipidic cohorts by virtue of its antioxidant property. It was also observed that the treatment with the AEAE reduced food intake negatively interfering weight accretion. Beyond that, the treatment with AEAE interfered in the SOD and catalase expression and inhibited phosphorylation of IKK thus suggesting that the observed hypoglycemiant power may be related to its known antioxidant potential. No sings of toxicity or hemolysis were detectaed at indicating that, at the concentrations evaluated, the extract was not toxic to normal cells. CONCLUSION The AEAE showed a hypoglycemiant effect in the normolipidic mice that received the control diet, but not in those that were made glucose-intolerant by consuming a high-fat fed. The extract also exhibited substantial protection against hemolysis and oxidative stress. Moreover, no signs of toxicity were evident at 2000 mg/kg of body weight.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Talinum paniculatum (Jacq.) Gaertn. (Talinaceae), popularly known as "major gomes" and "erva gorda", is a non-conventional food plant extensively distributed throughout the Brazilian territory. In Brazilian folk medicine, this species is used as aphrodisiac, to treat gastrointestinal problems, and as a cardioprotective agent. However, there are no reports in the literature proving its cardiovascular effects. AIM To perform a whole-ethnopharmacological investigation of the cardiorenal properties of the ethanol soluble fraction from T. paniculatum (ESTP) in Wistar rats. MATERIAL AND METHODS First, plant samples were collected, properly identified and a morpho-anatomical characterization was carried out to provide quality control parameters. Then, ESTP was obtained and its chemical profile was determined by LC-DAD-MS. In addition, an acute toxicity assay was conducted in female Wistar rats in order to observe any toxic effects after one single administration. Finally, the diuretic and hypotensive potential of ESTP (30, 100 and 300 mg/kg) were investigated in male rats followed by the evaluation of its possible effects on peripheral vascular resistance. RESULTS Chemical compounds identified from ESTP were chlorogenic acids, amino acids, nucleosides, O-glycosylated flavones and organic acids. No signs of toxicity as well as no changes in urine volume or electrolyte elimination were observed after ESTP acute treatment. On the other hand, prolonged treatment with all doses of ESTP significantly increased urine volume and electrolyte excretion (Na+, K+ and Cl-) without affecting blood pressure or heart rate. Apparently, these effects are involved with the activation of the small conductance calcium-activated potassium channels contributing to the increase of renal blood flow and glomerular filtration rate. CONCLUSION Data presented show important information about the ethnomedicinal properties of T. paniculatum. In addition, the study presents the ESTP as a possible herbal medicine, especially when a sustained diuretic effect is required.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Although Luehea divaricata Mart. (Malvaceae) is popularly used by the population of the Brazilian Pantanal for the treatment of different types of kidney diseases, no study has been carried out to prove this ethnobotanical indication. AIM To investigate the possible cardiorenal effects of an herbal preparation obtained from L. divaricata leaves. MATERIALS AND METHODS First, to provide quality control standards, a detailed morphological and microchemical characterization of L. divaricata leaves was performed. Then, the purified aqueous extract was obtained from the leaves of this species (ESLD) and a thorough phytochemical characterization was performed. Subsequently, acute oral toxicity test was performed after single administration of different doses (5, 50, 300, 2000mg/kg) in male and female Wistar rats. Finally, the diuretic, hypotensive and antioxidant properties of ESLD (30, 100, 300mg/kg) were evaluated after acute and prolonged treatment and the role of angiotensin converting enzyme, aldosterone, vasopressin, and nitric oxide in these effects was investigated. RESULTS Analyses performed by liquid chromatography-mass spectrometry showed that the main secondary metabolites present in ESLD were flavonol O-glycosides and flavone C-glycosides. Acute and prolonged treatment with ESLD was able to expressively increase urinary volume and electrolyte excretion. Mean blood pressure and systolic blood pressure were also significantly reduced after acute treatment. Moreover, treatment with ESLD was able to reduce thiobarbituric acid reactive species and increase serum nitrate levels. CONCLUSION The data obtained showed that ESLD has an important diuretic and hypotensive effect, which is probably dependent on the reduction of oxidative stress and increased bioavailability of nitric oxide.

Alismatis rhizoma (AR), the dried rhizoma of Alisma orientale Juzepzuk (Alismataceae), is a traditional Chinese medicine. AR is an important part of many prescriptions and is commonly used as a diuretic agent in Asia. This study aimed to evaluate the diuretic effects of total triterpene extract (TTE) and triterpene component compatibility (TCC, the mixture of alisol B 23-acetate, alisol B, alisol A 24-acetate, alisol A, and alisol C 23-acetate) of AR in saline-loaded rats. The optimal diuretic TCC of AR was optimized using a uniform design. Different doses (5, 20, and 40 mg/kg) of TTE and TCC groups (N1–N8) were orally administered to rats. Urinary excretion rate, pH, and electrolyte excretion were measured in the urine of saline-loaded rats. Results showed that TTE doses increased urine volume and electrolyte excretion compared with the control group. All uniformly designed groups of TCC also increased urine excretion. In addition, optimal diuretic TCC was calculated (alisol B 23-acetate: alisol B: alisol A 24-acetate: alisol A: alisol C 23-acetate 7.2:0.6:2.8:3.0:6.4) and further validated by saline-loaded rats. This study demonstrated that TTE presented a notable diuretic effect by increasing Na+, K+, and Cl− displacements. The most suitable TTC compatible proportion of alisol B 23-acetate: alisol B: alisol A 24-acetate: alisol A: alisol C 23-acetate for diuretic activity was validated, and triterpenes were the material basis for the diuretic activity of AR.
