Abstract
A multicomponent-derived synthesis of arylidene isoquinolinones decorated with phenolic moieties is described. The series demonstrated good DPPH trapping and, in the case of sinapic acid-containing analogs, excellent activity against lipoperoxidation; EPR also demonstrated that one derivative scavenged hydroxyl radicals. In addition, some compounds showed excellent inhibition of α-glucosidase activity and, according to both Lineweaver-Burk plots and molecular docking, they act as non-competitive or mixed inhibitors. In vitro assay also demonstrated that two compounds significantly reduced the plasma glucose levels after sucrose administration. In summary, the studied isoquinolinones become novel compounds with dual action (antioxidant and α-glucosidase inhibition) against diabetes and related metabolic diseases, whose optimization would lead to more potent candidates.

Abstract
The aim of this work was to evaluate the vasorelaxant and antihypertensive effects of a standardized precipitate of the hydroalcoholic extract from Agastache mexicana (PPAm), comprising ursolic acid, oleanolic acid, acacetin, luteolin and tilianin, among others. In the ex vivo experiments, preincubation with L-NAME (nonspecific inhibitor of nitric oxide synthases) reduced the relaxation induced by PPAm; nevertheless, preincubation with indomethacin (nonspecific inhibitor of cyclooxygenases) did not generate any change in the vasorelaxation, and an opposed effect was observed to the contraction generated by CaCl2 addition. Oral administration of 100 mg/kg of PPAm induced a significant acute decrease in diastolic (DBP) and systolic (SBP) blood pressure in spontaneously hypertensive rats, without changes in heart rate. Additionally, PPAm showed a sustained antihypertensive subacute effect on both DBP and SBP for 10 days compared to the control group. On the other hand, human umbilical vein cells treated with 10 µg/mL of PPAm showed a significant reduction (p < 0.05) in intracellular adhesion molecule-1, compared to the control, but not on vascular cell adhesion molecule-1. In conclusion, PPAm induces a significant antihypertensive effect in acute- and subacute-period treatments, due to its direct vasorelaxant action on rat aortic rings through NO production and Ca2+ channel blockade.

Abstract
Salvia hispanica L., commonly known as chía, and its seeds have been used since ancient times to prepare different beverages. Due to its nutritional content, it is considered a dietary ingredient and has been reported with many health benefits. Chia seed components are helpful in cardiovascular disease (CVD) by reducing blood pressure, platelet aggregation, cholesterol, and oxidation. Still, its vasodilator effects on the vascular system were not reported yet. The hexanic (HESh), dichloromethanic (DESh), and methanolic (MESh) extracts obtained from chía seeds were evaluated on an aortic ring ex-vivo experimental model. The vasorelaxant efficacy and mechanism of action were determined. Also, phytochemical data was obtained through 13C NMR-based dereplication. The MESh extract showed the highest efficacy (Emax = 87%), and its effect was partially endothelium-dependent. The mechanism of action was determined experimentally, and the vasorelaxant curves were modified in the presence of L-NAME, ODQ, and potassium channel blockers. MESh caused a relaxing effect on KCl 80 mM-induced contraction and was less potent than nifedipine. The CaCl2-induced contraction was significantly decreased compared with the control curve. Phytochemical analysis of MESh suggests the presence of mannitol, previously reported as a vasodilator on aortic rings. Our findings suggest NO-cGMP pathway participation as a vasodilator mechanism of action of S. hispanica seeds; this effect can be attributed, in part, to the mannitol presence. S. hispanica could be used in future research focused on antihypertensive therapies.

Abstract
Asthma is a condition in which a person's airways become inflamed, narrowed, and produce greater amounts of mucus than normal. It can cause shortness of breath, chest pain, coughing, or wheezing. In some cases, symptoms may be exacerbated. Thus, the current study was designed to determine the mechanism of action of 6-aminoflavone (6-NH2F) in ex vivo experiments, as well as to determine its toxicity in acute and sub-chronic murine models. Tissues were pre-incubated with 6-NH2F, and concentration-response curves to carbachol-induced contraction were constructed. Therefore, tracheal rings pre-treated with glibenclamide, 2-aminopyridine, or isoproterenol were contracted with carbachol (1 µM), then 6-NH2F relaxation curves were obtained. In other sets of experiments, to explore the calcium channel role in the 6-NH2F relaxant action, tissues were contracted with KCl (80 mM), and 6-NH2F was cumulatively added to induce relaxation. On the other hand, tissues were pre-incubated with the test sample, and after that, CaCl2 concentration-response curves were developed. In this context, 6-NH2F induced significant relaxation in ex vivo assays, and the effect showed a non-competitive antagonism pattern. In addition, 6-NH2F significantly relaxed the contraction induced by KCl and CaCl2, suggesting a potential calcium channel blockade, which was corroborated by in silico molecular docking that was used to approximate the mode of interaction with the L-type Ca2+ channel, where 6-NH2F showed lower affinity energy when compared with nifedipine. Finally, toxicological studies revealed that 6-NH2F possesses pharmacological safety, since it did not produce any toxic effect in both acute and sub-acute murine models. In conclusion, 6-aminoflavone exerted significant relaxation through calcium channel blockade, and the compound seems to be safe.

Abstract
Plantago australis Lam. Subsp. hirtella (Kunth) Rahn is a medicinal plant used as a diuretic, anti-inflammatory, antibacterial, throat cancer treatment and for the control of diabetes. P. australis was collected in the state of Morelos, México. The hydroalcoholic extract (HAEPa) of P. australis was obtained by maceration and concentrated in vacuo. Once dry, it was evaluated through an oral glucose tolerance test (OGTT) in normoglycemic mice and in a non-insulin-dependent diabetic mice model. The expression of PPARγ and GLUT-4 mRNA was determined by rt-PCR, and GLUT-4 translocation was confirmed by confocal microscopy. The toxicological studies were conducted in accordance with the guidelines suggested by the OECD, sections 423 and 407, with some modifications. HAEPa significantly decreased glycemia in OGTT curves, as well as in the experimental diabetes model compared to the vehicle group. In vitro tests showed that HAEPa induced an α-glucosidase inhibition and increased PPARγ and GLUT-4 expression in cell culture. The LD50 of HAEPa was greater than 2000 mg/kg, and sub-chronic toxicity studies revealed that 100 mg/kg/day for 28 days did not generate toxicity. Finally, LC-MS analysis led to the identification of verbascoside, caffeic acid and geniposidic acid, and phytochemical approaches allowed for the isolation of ursolic acid, which showed significant PPARγ overexpression and augmented GLUT-4 translocation. In conclusion, HAEPa induced significant antidiabetic action by insulin sensitization through PPARγ/GLUT-4 overexpression.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bocconia arborea S. Watson (Papaveraceae) is known as "palo llora sangre" and is used in Mexican traditional medicine for the treatment of infections, it is also used as anxiolytic, analgesic, and antidiabetic, among others. AIM OF THE STUDY to evaluate the antinociceptive and gastroprotective activities of extracts from B. arborea and dihydrosanguinarine (DHS) in murine models. MATERIALS AND METHODS Organic extracts [hexane (HEX), dichloromethane (DCM) and methanol (MeOH)] were obtained by maceration. DHS was isolated and purified from HEX and DCM by precipitation and chromatographic column, respectively. Organic extracts and DHS were evaluated to determine their antinociceptive effect using formalin test in murine model. Also, the ambulatory effect of the HEX and DHS was determined in Open field test. The possible mechanism of action of DHS was explored in the presence of naltrexone (NTX, 1 mg/kg, i.p.), and picrotoxin (PTX, 1 mg/kg, i.p.). Gastric damage as possible adverse effect or gastroprotection were also investigated. Whereas DHS acute toxicological study was done, and 100 mg/kg of DHS was examined by electroencephalographic (EEG) analysis to discard neurotoxic effects. RESULTS The B. arborea extracts significantly showed effects in both neurogenic and inflammatory phases of the formalin test, where the HEX extract reached the major antinociceptive effect. A significant and dose-response (10, 30, and 100 mg/kg) antinociceptive activity was observed with the HEX (ED50 = 69 mg/kg) and DHS (ED50 = 85 mg/kg) resembling the effect of the reference analgesic drug tramadol (30 mg/kg). The significant effect of DHS was inhibited in the presence of NTX and PTX. Neither the extracts or DHS produced sedative effects or gastric damage per se at antinociceptive doses. The EEG analysis demonstrated central depressant activity but not sedative or neurotoxic effects at the highest antinociceptive dosage tested, and LD50 is higher than 2000 mg/kg. CONCLUSIONS HEX, DCM, and MeOH extracts showed significant antinociceptive activity, and DHS was identified as one of bioactive compounds without producing sedative, neurotoxic or gastric damage effects, as possible adverse effects reported for analgesic drugs. A role of opioid and GABAA neurotransmission appears to be involved as mechanisms of action of DHS, suggesting its potential for pain therapy and reinforcing the traditional use of B. arborea.

Abstract
In current work, we prepared a series of nine 4-benzyloxy-5-benzylidene-1,3-thiazolidine-2,4-diones using a two-step pathway. Compounds 1-9 were tested in vitro using a set of three proteins recognized as important targets in diabetes and related diseases: PPARα, PPARγ, and GLUT-4. Compounds 1-3, 5, and 7 showed significant increases in the mRNA expression of PPARγ and GLUT-4, whereas compounds 1-3 did it over PPARα. Compounds 1-3 were identified as a dual PPAR α/γ modulators and were selected for evaluating the in vivo antidiabetic action at 100 mg/kg dose, being orally actives and decreasing blood glucose concentration in a hyperglycemic mice model, as well as reducing the triacylglycerides levels in normolipidemic rats. Docking and molecular dynamics studies were conducted to clarify the dual effect and binding mode of compounds 1-3 on both PPARs. Compounds 2 and 3 exhibited robust in vitro and in vivo efficacy and could be considered dual PPAR modulators with antidiabetic and antidyslipidemic effects.

Abstract
Objective:
the aim of this study was to determine the vasorelaxant effect of semisynthetic derivatives of ursolic acid and to establish the mode of action, and the antihypertensive effect of the most active compound.
Methods:
Isolated aorta rat rings (ex vivo assay), with and without endothelium, were used to determine the vasorelaxant effect of seven semisynthetic derivatives of ursolic acid (UA-01 to UA-07). Then, the effect of the most active compound was studied in ex vivo assay using L-NAME, ODQ and indomethacin to determine its mode action. Finally, the in vivo cardiovascular effect and molecular docking of the most active compound were determined.
Results:
UA-07 was the most potent compound of the derivatives, since UA-07 induced significant relaxant effect in a concentration- and endothelium-dependent manners (Emax = 79.09% and EC50 = 110 µM), on aortic rat rings pre-contracted with noradrenaline (NA, 0.1 µM). Also, endothelium-derived nitric oxide seems to be involved in the mechanism of action of UA-07, because pre-incubation with L-NAME (a NOS inhibitor) and ODQ (a soluble guanylate cyclase inhibitor) significantly reduced its vasorelaxant effect. Further, UA-07 showed a similar binding affinity as ursolic acid on eNOS C1 binding pocket using in silico studies. Finally, treatment with UA-07 (50 mg/Kg) on spontaneously hypertensive rats (SHR) significantly decreased diastolic blood pressure during seven hours.
Conclusion:
These results demonstrate the significant antihypertensive effect of UA-07, possibly through NO/cGMP system.

Abstract
Four isobutyric acids (two nitro and two acetamido derivatives) were prepared in two steps and characterized using spectral analysis. The mRNA concentrations of PPARγ and GLUT-4 (two proteins documented as key diabetes targets) were increased by 3T3-L1 adipocytes treated with compounds 1–4, but an absence of in vitro expression of PPARα was observed. Docking and molecular dynamics studies revealed the plausible interaction between the synthesized compounds and PPARγ. In vivo studies established that compounds 1–4 have antihyperglycemic modes of action associated with insulin sensitization. Nitrocompound 2 was the most promising of the series, being orally active, and one of multiple modes of action could be selective PPARγ modulation due to its extra anchoring with Gln-286. In conclusion, we demonstrated that nitrocompound 2 showed strong in vitro and in vivo effects and can be considered as an experimental antidiabetic candidate.

Abstract
The current study aimed to determine the antidiabetic and antidyslipidemic activities of moronic acid methyl ester (1) by in vivo, in vitro, in silico and molecular biology studies. Compound 1 was evaluated to establish its dose-dependent antidiabetic and antihyperglycemic (50 mg/kg) activities, in diabetic and normoglycemic male CD1 mice, respectively. Also, compound 1 was subjected to a sub-acute study (50 mg/kg/day for eight days) to determine blood biochemical profiles and the expression of PTP-1B, GLUT4, PPAR-α, PPAR-γ, adiponectin, IL-1β, and MCP1 in adipose tissue of animals after treatment. Different doses in acute administration of 1 decreased glycemia (p < 0.05), compared with vehicle, showing greater effectiveness in the range 50-160 mg/kg. Also, the oral glucose tolerance test (OGTT) showed that 1 induced a significant antihyperglycemic action by opposing the hyperglycemic peak (p < 0.05). Moreover, 1 subacute administration decrease glucose and triglycerides levels after treatment (p < 0.05); while the expression of PPAR-α and γ, adiponectin and GLUT4 displayed an increase (p< 0.05) compared with the diabetic control group. In conclusion, compound 1 showed antihyperglycemic, antidiabetic and antidyslipidemic effects in normal and diabetic mice, probably due to insulin sensitization through increase mRNA expression of GLUT4, PPAR-α, PPAR-γ and adiponectin genes.

Abstract
Several 4H-pyran derivatives were designed and synthesized previously as vasorelaxant agents for potential antihypertensive drugs. In this context, the objective of the present investigation was to determine the functional mechanism of vasorelaxant action of 6-amino-3-methyl-4-(2-nitrophenyl)-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (1: ) and its in vivo antihypertensive effect. Thus, compound 1: showed significant vasorelaxant action on isolated aorta rat rings pre-contracted with serotonin or noradrenaline, and the effect was not endothelium-dependent. Compound 1: induced a significant relaxant effect when aortic rings were contracted with KCl (80 mM), indicating that the main mechanism of action is related to L-type calcium channel blockade. Last was corroborated since compound 1: induced a significant concentration-dependent lowering of contraction provoked by cumulative CaCl2 adding. Moreover, compound 1: was capable to block the contraction induced by FPL 64176, a specific L-type calcium channel agonist, in a concentration-dependent manner. On the other hand, docking studies revealed that compound 1: interacts on two possible sites of the L-type calcium channel and it had better affinity energy (-7.80+/-0.00 kcal/mol on the best poses) than nifedipine (-6.86+/-0.14 kcal/mol). Finally, compound 1: (50 mg/kg) showed significant antihypertensive activity, lowering the systolic and diastolic blood pressure on spontaneously hypertensive rats (SHR) without modifying heart rate.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Achillea millefolium L. (Asteraceae), known as yarrow (milenrama), is a plant used in Mexican traditional medicine for the treatment of hypertension, diabetes, and related diseases. AIM To determine the vasorelaxant and antihypertensive effect of A. millefollium and to isolate the main bioactive antihypertensive agents. MATERIALS AND METHODS Organic (hexane, dichloromethane and methanol) and hydro-alcohol (Ethanol-H2O: 70:30) extracts obtained from flowers, leaves and stems were evaluated on isolated aorta rat rings with and without endothelium to determine their vasorelaxant effect. Hexane extract from flowers (HEAmF) was studied to evaluate its antihypertensive effect on spontaneously hypertensive rats (SHR). From HEAmF, bioactive compounds were obtained by bio-guided phytochemical separation through chromatography. RESULTS Organic extracts showed the best vasorelaxant activity. Hexane extract from flowers was the most potent and efficient ex vivo vasorelaxant agent, showing significant decrease of systolic and diastolic blood pressure in SHR (p < 0.05). Phytochemical separation of HEAmF yielded two epimeric sesquiterpene lactones: leucodin (1) and achillin (2), the major components of the extract. Both 1 and 2 showed similar vasorelaxant action ex vivo (p < 0.05), and their effects where modified by L-NAME (10 μM, nitric oxide synthase inhibitor), by ODQ (1 μM, soluble guanylyl cyclase inhibitor), and also relaxed the contraction induced by KCl (80 mM). Finally, 1 and 2 intragastric administration (50 mg/kg) decreased systolic and diastolic blood pressure in SHR. CONCLUSIONS Achillea millefolium showed antihypertensive and vasorelaxant effects, due mainly to leucodin and achillin (epimers). Both compounds showed antihypertensive activity by vasorelaxation putatively by endothelium-dependent NO release and cGMP increase, as well as by calcium channels blockade.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tagetes lucida Cav. commonly known as "yauhtli" or "pericón" is used in Mexican traditional medicine for the treatment of anxiety, depressant diseases, pain, hypertension, among others. AIM To evaluate the antihypertensive and vasorelaxant modes of action of a crude ethanolic extract from T. lucida aerial parts and to isolate the bioactive compounds. MATERIALS AND METHODS Ethanolic extract was tested in an in vivo assay in SHR rats by intragastric administration at 10 and 100 mg/kg dosages, to measure and to compare hemodynamic parameters like diastolic and systolic blood pressure and heart rate. Also, extract (3.03-1000 μg/ml), fractions (3.03-1000 μg/ml) and pure isolated compounds (1.75-550 μM) were evaluated on isolated aortic rings contracted with noradrenaline (0.1 μM) to determine their vasorelaxant effect and extract-mode of action. RESULTS Ethanolic extract of T. lucida lowered systolic and diastolic blood pressure on SHR rats without heart rate modification (P > 0.05). Moreover, the extract showed concentration-dependent relaxant effect in a partially endothelium-dependent manner (P < 0.05), through NO/cGMP system activation and calcium channel blockade. 6,7,8-trimethoxycoumarin (1), 6,7-dimethoxycoumarin (2), and 7-methoxycoumarin (3) from T. lucida are the main bioactive compounds of the extract and showed significant vasorelaxant activity. CONCLUSIONS Results provide evidence and endorsed the antihypertensive properties attributed to T. lucida in traditional medicine, which is produced by vasorelaxant effect mainly through multitarget NO/cGMP system activation and calcium channel blockade. Coumarin derivatives 1, 2 and 3 are the responsible of the vasorelaxant activity.

Abstract
Smooth muscle is a central structure involved in the regulation of airway tone. In addition, it plays an important role in the development of some pathologies generated by alterations in contraction, such as hypercontractility and the airway hyperresponsiveness observed in asthma. The molecular processes associated with smooth muscle contraction are centered around myosin light chain (MLC) phosphorylation, which is controlled by a balance in the activity of myosin light-chain kinase (MLCK) and myosin light-chain phosphatase (MLCP). MLCK activation depends on increasing concentrations of intracellular Ca2+, while MLCP activation is independent of Ca2+. MLCP contains a phosphatase subunit (PP1c) that is regulated through myosin phosphatase target subunit 1 (MYPT1) and other subunits, such as glycogen-associated regulatory subunit and myosin-binding subunit 85 kDa. Interestingly, MLCP inhibition may contribute to exacerbation of smooth muscle contraction by increasing MLC phosphorylation to induce hypercontractility. Many pathways inhibiting MLCP activity in airway smooth muscle have been proposed and are focused on inhibition of PP1c, inhibitory phosphorylation of MYPT1 and dissociation of the PP1c-MYPT1 complex.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Achillea millefolium L. (Asteraceae) is used for the treatment of respiratory diseases, diabetes, and hypertension. AIM to explore its tracheal relaxant properties and clarify its functional mechanism of action on smooth muscle cells, which allow us to propose it as a potential anti-asthmatic drug. MATERIAL AND METHODS organic and hydro-alcoholic extracts from A. millefolium were obtained by macerations, then their relaxing effect on ex vivo isolated rat trachea rings was determined. Most active extract (hexanic extract, EHAm) was studied to determine its functional mechanism of action using synergic, antagonist and inhibitor agents related with the contraction/relaxation process of the smooth muscle. Also, EHAm was subjected to bio-guided fractionation by open-column chromatography (on silica gel) using cyclohexane-EtOAc (80:20) in an isocratic way to isolate main bioactive compounds. RESULTS organic and hydro-alcoholic extracts showed relaxant effect in a concentration-response dependent manner, being EHAm the most active. The functional mechanism of action indicates that EHAm induced a non-competitive antagonism to the muscarinic receptors ; in addition, the NO/cGMP pathway is involved in the relaxation process of the tracheal smooth muscle. However, the most important mechanism of action showed by EHAm was related with the calcium channel blockade influx into the smooth muscle cells. On the other hand, epimeric sesquiterpene lactones leucodin (1) and achillin (2) were isolated and purified, which are responsible for the observed smooth muscle relaxant activity of the extract. CONCLUSION hexanic extract of A. millefollium induced a significant relaxant effect on tracheal rat rings by calcium channel blockade and NO release.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE CORDIA MORELOSANA: Standley (Boraginaceae) is commonly used in folk medicine for the treatment of diarrhoea, kidney inflammation, diabetes, lung pain, bronchitis, asthma, hoarseness, cough and fever. AIM Current work was conducted to develop a bio-guided isolation of antidiabetic compounds from ethanolic extract of Cordia morelosana (EECm). MATERIAL AND METHODS The phytochemical bio-guided study was conducted by successive chromatographic techniques, and isolated compounds were characterized by 1D and 2D-NMR experiments. The in vivo antihyperglycemic and antidiabetic activities of EECm (100 mg/kg), and methyl rosmarinate (MR, 50 mg/kg) were determined on normoglycemic and diabetic murine models. Additionally, the in vitro activity was conducted to determine α-glucosidase inhibitory effect, and PPARs, GLUT4 and FATP expression on 3T3-L1 cells by RT-PCR. Acute and sub-chronic toxicological studies for EECm were conducted on rats, following the OECD guidelines (No. 420 and 407). RESULTS EECm promotes significant α-glucosidase inhibition (55.6%) at 1 mg/kg respect to the control. Also, EECm (100 mg/kg) showed significant antihyperglycemic effect on oral glucose tolerance test (OGTT), and in non-insulin dependent type 2 diabetes (NIDD) model, had antidiabetic activity (p < 0.001) compared to controls. The bio-guided isolation allowed to obtain four known compounds described as rosmarinic acid (RA), methyl rosmarinate (MR), nicotiflorine and 1-O-methyl-scyllo-inositol. On the other hand, MR showed significant antidiabetic and anthiyperglycemic activities (p < 0.05), and overexpression of PPARγ, PPARα, GLUT-4 and FATP than control. Docking studies were conducted with PPARγ and PPARα, showing interesting binding mode profile on those targets. Finally, EECm displayed a LD50 > 2000 mg/kg and sub-chronic toxicological study reveals no toxic signs in animals tested compared to control. CONCLUSION EECm showed significant antihyperglycemic and antidiabetic actions being RA and MR the main antidiabetic metabolites.

Abstract
We prepared a series of 10 carbamates derivatives based on two common antiprotozoal drugs: metronidazole (1–5) and secnidazole (6–10). The compounds were tested in vitro against a set of two amitochondriate protozoa: Giardia duodenalis and Trichomonas vaginalis. Compounds 1–10 showed strong antiprotozoal activities, with potency values in the low micromolar-to-nanomolar range, being more active than their parent drugs. Metronidazole carbamate (1) was the most active of the series, with nanomolar activities against G. duodenalis (IC50 = 460 nM) and T. vaginalis (IC50 = 60 nM). The potency of compound 1 was 10 times greater than that of metronidazole against both parasites. None of compounds showed in vitro cytotoxicity against VERO cells tested at 100 µM. Molecular dynamics of compounds 1–10, secnidazole, and metronidazole onto the ligand binding site of pyruvate–ferredoxin oxidoreductase of T. vaginalis and the modeled β-tubulin of G. duodenalis revealed putative molecular interactions with key residues in the binding site of both proteins implicated in the mode of action of the parent drugs.

Abstract
Flavonoids are naturally occurring compounds that show health benefits on the liver. However, there is little investigation about identification and evaluation of new flavonoid-containing drugs for cholestatic liver disease, one of the most common liver illnesses. We aimed to a systematic search regarding efficacy of flavonoids for treatment of cholestatic liver disease, and then evaluate naringenin (NG) as representative flavonoid in an obstructive cholestasis model. We searched for information of experimental and clinical studies in four major databases without time and language limits. Intervention was defined as any flavonoid derivate compared with other flavonoid, placebo, or without comparator. In addition, we evaluated NG on a bile duct-ligated model in order to contribute evidence of its actions. Eleven experimental reports that support the efficacy of flavonoids in cholestatic liver disease were identified. However, there was no homogeneity in efficacy endpoints evaluated and methodology. On the other hand, NG showed beneficial effects by improving specific metabolic (cholesterol and lipoproteins) and liver damage (bilirubin and alkaline phosphatase) biomarkers. The review lacks homogeneous evidence about efficacy of flavonoids in experimental settings, and is susceptible to risk for bias. NG only showed improvements in specific disease biomarkers. More investigation is still needed to determine its potential for drug development.

Abstract
Agastache mexicana has gained importance during the last decade as a natural source of bioactive compounds, mainly due to the antidiabetic, antihyperlipidemic, and vasorelaxant effects derived from its flavonoids, particularly tilianin. The goal of this work was to evaluate the production of tilianin during the in-vitro process of morphogenesis leading to plant regeneration and to investigate the vasorelaxant activity of its methanolic extracts. The cultures were established from nodal segments and leaf explants, inoculated on Murashige and Skoog (MS) media supplemented with various concentrations of benzyl aminopurine (BAP) alone or in combination with 2,4-Dichlorophenoxyacetic acid (2,4-D). Callus inductions were obtained in all treatments from both types of explants, but the presence of auxin was essential. Maximal shoot multiplication and elongation was achieved with 0.1 mg/l 2,4-D and 1.0 mg/l BAP from nodal- segment explants. Shoots were rooted in 75% MS medium and the plantlets were transferred to a greenhouse with 33% average survival. Analysis of tilianin production in methanolic extracts from calli (0.15-2.01 ± 0.06 mg/g dry weight), shoots (4.45 ± 0.01 mg/g DW), and whole plants (9.77 ± 0.02 mg/g DW) derived from in-vitro cultured nodal segments reveals that tilianin accumulation is associated with high cell differentiation and morphogenetic response to the plant-growth regulators. All of the extracts showed strong vasorelaxant activity, as compared to those of wild plant extracts. These results indicate that plant-tissue cultures of A. mexicana possess vast potential as a source of tilianin and other bioactive compounds.

Abstract
Previously, we described tracheal rat rings relaxation by several flavonoids, being 6-hydroxyflavone (6-HOF) the most active derivative of the series. Thus, its mechanism of action was determined in an ex vivo tracheal rat ring bioassay. The anti-asthmatic effect was assayed in in vivo OVAlbumin (OVA)-sensitized guinea pigs. Finally, the toxicological profile of 6-HOF was studied based on Organization of Economic Cooperation and Development guidelines with modifications. 6-HOF-induced relaxation appears to be related with receptor-operated calcium channel and voltage-operated calcium channel blockade as the main mechanism of action, and also through the production of relaxant second messengers NO and cGMP. Molecular docking supports that 6-HOF acts as calcium channel blocker and by activation of nitric oxide synthase. In addition, the in vivo anti-asthmatic experiments demonstrate the dose-dependent significant anti-allergic effect of 6-HOF induced by OVA, with best activity at 50 /kg. Finally, toxicological studies determined a LD50 > 2,000 mg/kg and, after 28 day of treatment with 6-HOF (50 mg/kg) by intragastric route, mice did not exhibit evidence of any significant toxicity. In conclusion, experiments showed that 6-HOF exerts significant relaxant activity through calcium channel blockade, and possibly, by NO/cGMP-system stimulation on rat trachea, which interferes with the contraction mechanism of smooth muscle cells in the airways. In addition, the flavonoid shows potential anti-asthmatic properties in an anti-allergic pathway. Furthermore, because the pharmacological and safety evidence, we propose this flavonoid as lead for the development of a novel therapeutic agent for the treatment of asthma and related respiratory diseases.

Abstract
In this study, we synthesized five N-Boc-L-tyrosine-based analogues to glitazars. The in vitro effects of compounds 1-5 on protein tyrosine phosphatase 1B (PTP-1B), peroxisome proliferator-activated receptor alpha and gamma (PPARα/γ), glucose transporter type-4 (GLUT-4) and fatty acid transport protein-1 (FATP-1) activation are reported in this paper. Compounds 1 and 3 were the most active in the in vitro PTP-1B inhibition assay, showing IC50s of approximately 44 μM. Treatment of adipocytes with compound 1 increased the mRNA expression of PPARγ and GLUT-4 by 8- and 3-fold, respectively. Moreover, both compounds (1 and 3) also increased the relative mRNA expression of PPARα (by 8-fold) and FATP-1 (by 15-fold). Molecular docking studies were performed in order to elucidate the polypharmacological binding mode of the most active compounds on these targets. Finally, a murine model of hyperglycemia was used to evaluate the in vivo effectiveness of compounds 1 and 3. We found that both compounds are orally active using an exploratory dose of 100 mg/kg, decreasing the blood glucose concentration in an oral glucose tolerance test and a non-insulin-dependent diabetes mellitus murine model. In conclusion, we demonstrated that both molecules showed strong in vitro and in vivo effects and can be considered polypharmacological antidiabetic candidates.

Abstract
This work presents the synthesis of two hybrid compounds (1 and 2) with thiazolidine-2,4-dione structure as a central scaffold which were further screened in combo (in vitro as PTP-1B inhibitors, in vivo antihyperglycemic activity, in silico toxicological profile and molecular docking). Compound 1 was tested in the enzymatic assay showing an IC50 = 9.6 ± 0.5 μM and compound 2 showed about a 50% of inhibition of PTP-1B at 20 μM. Therefore, compound 1 was chosen to test its antihyperglycemic effect in a rat model for non-insulin-dependent diabetes mellitus (NIDDM), which was determined at 50 mg/kg in a single dose. The results indicated that compound showed a significant decrease of plasma glucose levels that reached 34%, after a 7 h post-administration. Molecular docking was employed to study the inhibitory properties of thiazolidine-2,4-dione derivatives against Protein Tyrosine Phosphatase 1B (PDB ID: 1c83). Concerning to the two binding sites in this enzyme (sites A and B), compound 1 has shown the best docking score, which indicates the highest affinity. Finally, compounds 1 and 2 have demonstrated an in silico satisfactory pharmacokinetic profile. This shows that it could be a very good candidate or leader for new series of compounds with this central scaffold.

Abstract
OBJECTIVES To explore the antihyperglycaemic and antidiabetic effects and to determine the acute toxicity of 5-(4-chlorophenyl)-1-(2,4-dichloro-phenyl)-4-methyl-N-(piperidin-1-yl)-1H-pyrazole-3-carboxamide (ENP-9). METHODS The antihyperglycaemic effect of ENP-9 (50 mg/kg) was determined by oral glucose tolerance test (OGTT). Also, the acute (16, 50 and 160 mg/kg) and subacute (50 mg/kg/day for 10 days) antidiabetic effects of ENP-9 were determined. After subacute treatment, blood samples were analysed to determine glucose and lipid profiles. Also, an acute toxicity determination of ENP-9 was conducted followed the OECD recommendation. Molecular docking was performed using AutoDock 4.2.6 at human cannabinoid receptor 1 (PDB code 5TGZ). KEY FINDINGS Acute Administration of ENP-9 showed significant antidiabetic effect and decreased the maximum OGTT peak, compared to the control group (P < 0.05). Moreover, the 10 days treatment induced a decrease in plasma glucose levels, being significant at the end of the experiments (P < 0.05); however, triacylglycerols and cholesterol were not modified. Finally, LD50 of ENP-9 was estimated to be greater than 2000 mg/kg. Molecular docking suggests that ENP-9 may act as rimonabant does. CONCLUSIONS ENP-9 showed significant antihyperglycaemic and antidiabetic properties and also was demonstrated to be safety in the studied doses, which might allow future studies for its potential development as antidiabetic agent.

Abstract
Hit, Lead & Candidate Discovery Protein tyrosine phosphatase 1B (PTP-1B) has attracted interest as a novel target for the treatment of type 2 diabetes, this because its role in the insulin-signaling pathway as a negative regulator. Thus, the aim of current work was to obtain seven ursolic acid derivatives as potential antidiabetic agents with PTP-1B inhibition as main mechanism of action. Furthermore, derivatives 1-7 were submitted in vitro to enzymatic PTP-1B inhibition being 3, 5, and 7 the most active compounds (IC50 = 5.6, 4.7, and 4.6 μM, respectively). In addition, results were corroborated with in silico docking studies with PTP-1B orthosteric site A and extended binding site B, showed that 3 had polar and Van der Waals interactions in both sites with Lys120, Tyr46, Ser216, Ala217, Ile219, Asp181, Phe182, Gln262, Val49, Met258, and Gly259, showing a docking score value of -7.48 Kcal/mol, being more specific for site A. Moreover, compound 7 showed polar interaction with Gln262 and Van der Waals interactions with Ala217, Phe182, Ile219, Arg45, Tyr46, Arg47, Asp48, and Val49 with a predictive docking score of -6.43 kcal/mol, suggesting that the potential binding site could be localized in the site B adjacent to the catalytic site A. Finally, derivatives 2 and 7 (50 mg/kg) were selected to establish their in vivo antidiabetic effect using a noninsulin-dependent diabetes mice model, showing significant blood glucose lowering compared with control group (p < .05).

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Achillea millefolium L. (Asteraceae) is a perennial herb used in Mexican folk medicine for treatment of several pathologies, including inflammatory and spasmodic gastrointestinal disorders, hepatobiliary complaints, overactive cardiovascular, respiratory ailments and diabetes. AIM OF THE STUDY To evaluate the potential antidiabetic effect in vivo and to establish the potential mode of action through in vitro approaches of Achillea millefolium. MATERIALS AND METHODS The antidiabetic effect of hydroalcoholic extract of Achillea millefolium (HAEAm) was evaluated on the oral glucose tolerance tests, in normoglycemic and experimental Type 2 diabetic mice models. In addition, we evaluated the possible mode of action in in vitro assays to determine α-glucosidases inhibition, the insulin secretion and calcium mobilization in RINm5F cells and PPARγ and GLUT4 expression in 3T3-L1 cells. RESULTS HAEAm showed significant glucose diminution on oral glucose tolerance test and in acute experimental Type 2 diabetic assay with respect to the control (p < 0.05). In addition, HAEAm promoted the α-glucosidases inhibition by 55% at 1mg/ml respect to control. On the other hand, HAEAm increased the PPARγ (five-times) and GLUT4 (two-fold) relative expression than control (p < 0.05). Finally, HAEAm significantly increased the insulin secretion and [Ca2+]i compared with control. CONCLUSION The HAEAm possesses in vivo antidiabetic effect, having such effect through multitarget modes of action that involve antihyperglycemic (α-glucosidases inhibition), hypoglycemic (insulin secretion) and potential insulin sensitizer (PPARγ/GLUT4 overexpression) actions.

Abstract
We have synthesized a small series of five 3-[4-arylmethoxy)phenyl]propanoic acids employing an easy and short synthetic pathway. The compounds were tested in vitro against a set of four protein targets identified as key elements in diabetes: G protein-coupled receptor 40 (GPR40), aldose reductase (AKR1B1), peroxisome proliferator-activated receptor gama (PPARγ) and solute carrier family 2 (facilitated glucose transporter), member 4 (GLUT-4). Compound 1 displayed an EC50 value of 0.075 μM against GPR40 and was an AKR1B1 inhibitor, showing IC50 = 7.4 μM. Compounds 2 and 3 act as slightly AKR1B1 inhibitors, potent GPR40 agonists and showed an increase of 2 to 4-times in the mRNA expression of PPARγ, as well as the GLUT-4 levels. Docking studies were conducted in order to explain the polypharmacological mode of action and the interaction binding mode of the most active molecules on these targets, showing several coincidences with co-crystal ligands. Compounds 1–3 were tested in vivo at an explorative 100 mg/kg dose, being 2 and 3 orally actives, reducing glucose levels in a non-insulin-dependent diabetes mice model. Compounds 2 and 3 displayed robust in vitro potency and in vivo efficacy, and could be considered as promising multitarget antidiabetic candidates. This is the first report of a single molecule with these four polypharmacological target action.

Abstract
The design of compounds 1 and 2 was based on the similar scaffold of pharmacophoric groups for PPARγ and GPR40 agonists. In order to find new compounds with improved biological activity, the current manuscript describes a new dual PPARγ-GPR40 agonist. We synthesized two compounds, which were prepared following a multistep synthetic route, and the relative mRNA expression levels of PPARγ, GLUT4, and GPR40 were quantified in cell culture, as well as insulin secretion and [Ca2+] intracellular levels. Compound 1 showed a 7-times increase in the mRNA expression of PPARγ, which in turn enhanced the expression levels of GLUT4 respect to control and pioglitazone. It also showed an increase of 2-fold in the [Ca2+]i level allowing an increment on insulin release, being as active as the positive control (glibenclamide), causing also an increase of 2-fold in mRNA expression of GPR40. Furthermore, the compound 2 showed lower activity than the compound 1. The ester of 1 showed antidiabetic activity at a 50mg/kg single dose in streptozotocin-nicotinamide-induced diabetic mice model. In addition, we achieved a molecular docking study of compound 1 on PPARγ and GPR40 receptors, showing a great affinity for both targets. We observed important polar interactions between the carboxylic group and main residues into the binding pocket. Therefore, the compound 1 has a potential for the development of antidiabetic agents with newfangled dual action.

Abstract
In the current investigation, the physicochemical, biopharmaceutical and pharmacokinetic characterization of a new clofibric acid analog (Compound 1) was evaluated. Compound 1 showed affinity by lipophilic phase in 1 to 5 pH interval, indicating that this compound would be absorbed favorably in duodenum or jejunum. Also, Compound 1 possess two ionic species, first above of pH 4.43 and, the second one is present over pH 6.08. The apparent permeability in everted sac rat intestine model was 8.73 × 10-6 cm/s in duodenum and 1.62 × 10-5 cm/s in jejunum, suggesting that Compound 1 has low permeability. Elimination constant after an oral administration of 50 μg/kg in Wistar rat was 1.81 h-1, absorption constant was 3.05 h-1, Cmax was 3.57 μg/mL at 0.33 h, AUC0-α was 956.54 μ/mL·h and distribution volume was 419.4 mL. To IV administration at the same dose, ke was 1.21 h-1, Vd was 399.6 mL and AUC0-α was 747.81 μ/mL·h. No significant differences were observed between pharmacokinetic parameters at every administration route. Bioavailability evaluated was 10.4%. Compound 1 is metabolized to Compound 2 probably by enzymatic hydrolysis, and it showed a half-life of 9.24 h. With these properties, Compound 1 would be considered as a prodrug of Compound 2 with potential as an antidiabetic and anti dyslipidemic agent.

Abstract
CONTEXT Agastache mexicana (Kunth) Lint & Epling (Lamiaceae) is a plant used in Mexican traditional medicine for the treatment of hypertension, anxiety and so on. OBJECTIVE To determine the vasorelaxant effect and functional mode of action of dichloromethane-soluble extract from A. mexicana (DEAm) and isolate the constituents responsible for the pharmacological activity. MATERIALS AND METHODS Extracts were prepared from the aerial parts of A. mexicana (225.6 g) by successive maceration with hexane, dichloromethane and methanol (three times for 72 h at room temperature), respectively. DEAm (0.01-1000 μg/mL), fractions (at 174.27 μg/mL), acacetin and ursolic acid (UA) (0.5-500 μM) were evaluated to determine their vasorelaxant effect on ex vivo rat aorta ring model. In vivo UA antihypertensive action was determined on spontaneously hypertensive rats. RESULTS AND DISCUSSION DEAm induced a significant vasorelaxant effect in concentration-dependent and endothelium-independent manners (EC50 = 174.276 ± 5.98 μg/mL) by a calcium channel blockade and potassium channel opening. Bio-guided fractionation allowed to isolate acacetin (112 mg), UA (2.830 g), acacetin/oleanolic acid (OA) (M1) (155 mg) and acacetin/OA/UA (M2) (1.382 g) mixtures, which also showed significant vasodilation. UA significantly diminished diastolic (80 mmHg) and systolic blood pressure (120 mmHg), but heart rate was not modified. CONCLUSION DEAm produced significant vasorelaxant action by myogenic control cation. The presence of acacetin, OA and UA into the extract was substantial for the relaxant activity of DEAm. In vivo antihypertensive action of UA corroborates the use of A. mexicana as an antihypertensive agent on Mexican folk medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Brickellia cavanillesii (Asteraceae) (Cass.) A. Gray is one of the popular plants consumed in Central America and Mexico for the treatment of several diseases such as hypertension, diabetes and anxiety, among others. AIM OF THE STUDY To determine the anxiolytic-like effect of B. Cavanillesii and the safety of its use through toxicological studies. MATERIAL AND METHODS Anxiolytic-like effects of soluble-methanol extract of B. cavanillesii (MEBc) were evaluated in ambulatory activity (open-field test), hole-board test, cylinder of exploration, the elevated plus-maze and the potentiation of the sodium pentobarbital-induced hypnosis mice models. On the other hand, in vivo toxicological studies were conducted on acute and sub-acute mice models recommended by OECD. Active MEBc was subjected to phytochemical studies through conventional chromatographic techniques to isolate bioactive compounds. RESULTS MEBc (100mg/Kg) showed significant anxiolytic-like effect on animal model used (p<0.05). The phytochemical analysis of MEBc allowed the isolation of two major compounds nicotiflorin and acacetin, among others. Both compounds were found to be partially responsible for the anxiolytic-like effects. Moreover, a median lethal dose (LD50) higher than 2000mg/Kg was determined in mice and sub-acute oral administration of MEBc (100mg/Kg) did not alter body weight, clinical chemistry parameters (ALT and AST) and it did not induce any toxic nor alteration in the liver, kidney and heart functions. CONCLUSIONS In current investigation, we have shown that MEBc has a wide range of pharmacology-toxicology patterns. The results support further investigation of MEBc as a potential anxiolytic phytomedicinal agent.

Abstract
Compound 2-(3,4-dichlorophenoxy)-N-(2-morpholin-4-ylethyl)acetamide (1) was designed, prepared and the in vitro binding evaluation against σ1 and σ2 receptors was measured. Compound 1 showed high σ1 receptor affinity (Ki=42 nM) and it was 36-times more selective for σ1 than σ2 receptor. Also, it was performed a molecular docking of compound 1 into the ligand binding pocket homology model of σ1 receptor, showing a salt bridge between the ionized morpholine ring and Asp126, as well as important short contacts with residues Tyr120, His154 and Trp164. Ligand efficiency indexes and predicted toxicity analysis revealed an excellent intrinsic quality of 1. The antinociceptive effect of compound 1 was determined using the formalin test. The ipsilateral local peripheral (10-300 μg/paw) and intrathecal (100 μg/rat) administration of 1 produced a reduction in formalin-induced nociception. The in vivo results indicated that 1 may be effective in treating inflammatory pain.

Abstract
OBJECTIVE To determine the depressant-like effects and the possible mechanism of action of tilianin isolated from active methanol extract of Agastache mexicana (A. mexicana). Also, to establish the pharmacophoric requirements of tilianin, as a possible ligand of GABAA/BZD receptor, by the alignment of diazepam, CGS-9896 and diindole, using a previously described pharmacophoric model. METHODS Tilianin (30 to 300 mg/kg, ip. and 300 mg/kg, po.) and methanol crude extract (10 to 300 mg/kg, ip. and 300 mg/kg po.) from A. mexicana were evaluated for potential sedative and anxiolytic-like response drugs by using open-field, hole-board, cylinder of exploration, plus-maze and sodium pentobarbital-induced hypnosis mice methods. RESULTS Methanol extract and tilianin showed anxiolytic-like activity from a dosage of 30 mg/kg, ip. or 300 mg/kg, po. and were less potent than diazepam 0.1 mg/kg, a reference anxiolytic drug used. Moreover, depressant activity of both potentiates sodium pentobarbital (SP)-induced sleeping time. The anxiolytic-like effect of 30 mg/kg ip. observed for the extract and tilianin, by using the plus-maze model, was partially prevented in the presence of flumazenil (a GABAA/BZD antagonist, 5 mg/kg ip.) but not in the presence of WAY 100635 (a selective 5-HT1A receptor antagonist, 0.32 mg/kg, ip.). Pharmacophoric modeling alignments of three agonist of GABAA/BZD allow identify seven chemical features. Tilianin contains six of the seven features previously determined. CONCLUSIONS Results indicate that tilianin is one of the bioactive metabolites in the anxiolytic-like activity of A. mexicana, reinforcing its central nervous system uses, where GABAA/BZD, but not 5-HT1A, receptors are partially involved.

Abstract
We synthesized four 5-nitrothiazole (1-4) and four 6-nitrobenzothiazole acetamides (5-8) using an easy two step synthetic route. All compounds were tested in vitro against amitochondriate parasites Giardia intestinalis and Trichomonas vaginalis, showing excellent antiprotozoal effects. IC₅₀'s of the most potent compounds range from nanomolar to low micromolar order, being more active than their drugs of choice. Compound 1 (IC₅₀=122 nM), was 44-times more active than Metronidazole, and 10-fold more effective than Nitazoxanide against G. intestinalis and showed good trichomonicidal activity (IC₅₀=2.24 μM). This compound did not display in vitro cytotoxicity against VERO cells. The in vitro inhibitory effect of compounds 1-8 and Nitazoxanide against G. intestinalis fructose-1,6-biphosphate aldolase (GiFBPA) was evaluated as potential drug target, showing a clear inhibitory effect over the enzyme activity. Molecular docking of compounds 1, 4 and Nitazoxanide into the ligand binding pocket of GiFBPA, revealed contacts with the active site residues of the enzyme. Ligand efficiency metrics of 1 revealed optimal combinations of physicochemical and antiprotozoal properties, better than Nitazoxanide.

Abstract
Abstract
Objectives
This study was conducted to evaluate the vasorelaxant effect of the fungal alkaloids malbrancheamides on pre-contracted rat aorta rings. Also, we explored the probable mode of action using experimental and theoretical docking studies.
Methods
The vasorelaxant effect was assessed on rat aorta rings pre-contracted with noradrenaline (0.1 μm). The mechanism of action was evaluated using different inhibitors of the pathways involved in the vasorelaxation process, such as l-NAME, indomethacin, tetraethylammonium and atropine. The docking analyses were carried out with AutoDock 4.2 software using the crystallized structure of the cyclooxygenase domain of eNOS.
Key findings
Malbrancheamides (1–3) induced a significant vasorelaxant activity in a concentration- and endothelium-intact model in rat aorta rings, and a lesser effect in an endothelium-denuded model. Malbrancheamide-induced vasorelaxation was significantly weakened by pretreatment of endothelium-intact aortic rings with L-NAME (10 μm), indicating a nitrergic relaxant mechanism. Docking analysis predicted that 1–3 could activate eNOS throughout an allosteric fashion at C1 and C2 pockets.
Conclusions
Experimental evidence revealed that malbrancheamides induced both endothelium-independent and endothelium-dependent relaxant effects. According to theoretical studies, it is feasible that the endothelium-independent relaxation exerted by malbrancheamide could be mediated by its calmodulin inhibitory properties throughout an interference with myosin light chain phosphorylation and a positive modulation of eNOS.

Abstract
The asymmetric unit of the title compound, C13H14O3, contains two independent mol-ecules, A and B, that are inter-connected through an offset π-π inter-action [inter-centroid separation = 3.6087 (4) Å]. The fused benzene and pyran-2-one rings in each mol-ecule are essentially coplanar, having dihedral angles of 1.22 (12) and 1.57 (12)° for mol-ecules A and B, respectively. Similarly, the coumarin ring system and the 7-prop-oxy substituent are close to being coplanar [C-C-O-C torsion angles = 2.9 (2) and 1.4 (2)° for mol-ecules A and B, respectively]. In the crystal, the mol-ecules are connected by C-H⋯O hydrogen bonds, forming supra-molecular tapes along [100] that are linked into a three-dimensional network by C-H⋯π inter-actions, as well as by the aforementioned π-π inter-actions.

Abstract
Asthma is a chronic inflammatory disorder that causes contraction in the smooth muscle of the airway and blocking of airflow. Reversal the contractile process is a strategy for the search of new drugs that could be used for the treatment of asthma. This work reports the semisynthesis, ex vivo relaxing evaluation and SAR studies of a series of 18 coumarins. The results pointed that the ether derivatives 1-3, 7-9 and 13-15 showed the best activity (Emax = 100%), where compound 2 (42 μM) was the most potent, being 4-times more active than theophylline (positive control). The ether homologation (methyl, ethyl and propyl) in position 7 or positions 6 and 7 of coumarins lead to relaxing effect, meanwhile formation of esters generated less active compounds than ethers. The SAR analysis showed that it is necessary the presence of two small ether groups and the methyl group at position 4 (site 3) encourage biological activity through soft hydrophobic changes in the molecule, without drastically affecting the cLogP.

Abstract
Current work was conducted to evaluate the vasorelaxant effect of dihydrospinochalcone-A (1) and isocordoin (2), compounds type chalcone isolated from Lonchocarpus xuul, an endemic tree of the Yucatan Peninsula, Mexico. Compounds 1 and 2 were found to induce significant relaxant effect in a concentration-dependent manner on aortic rat rings pre-contracted with noradrenaline (NA, 0.1 μM). Compound 1 was the most active and its effect was endothelium-dependent (Emax=79.67% and EC50=21.46 μM with endothelium and Emax=23.58% and EC50=91.8 μM without endothelium, respectively). The functional mechanism of action for 1 was elucidated. Pre-incubation with L-NAME (unspecific nitric oxide synthase inhibitor), indomethacin (unspecific COX inhibitor), ODQ (soluble guanylyl cyclase inhibitor), atropine (cholinergic receptor antagonist), TEA (unspecific potassium channel blocker) reduced relaxations induced by 1. Oral administration of 50 mg/kg of compound 1 exhibited significant decrease in diastolic and systolic blood pressure in SHR rats. The heart rate was not modified. Compound 1 was docked with a crystal structure of eNOS. Dihydrospinochalcone-A showed calculated affinity with eNOS in the C1 binding pockets, near the catalytic site; Trp449, Trp447 and His373 through aromatic and π-π interactions, also His463 and Arg367 are the residues that make hydrogen bonds with the carbonyl and hydroxyl groups. In conclusion, dihydrospinochalcone-A induces a significant antihypertensive effect due to its direct vasorelaxant action on rat aorta rings, through NO/sCG/PKG pathway and potassium channel opening.
