Abstract
Fungal infections caused by Candida are still a public health concern. Particularly, the resistance to traditional chemotherapeutic agents is a major issue that requires efforts to develop new therapies. One of the most interesting approaches to finding new active compounds is drug repurposing aided by computational methods. In this work, two databases containing anticandidal agents and drugs were studied employing cheminformatics and compared by similarity methods. The results showed 36 drugs with high similarities to some candicidals. From these drugs, trimetozin, osalmid and metochalcone were evaluated against C. albicans (18804), C. glabrata (90030), and miconazole-resistant strain C. glabrata (32554). Osalmid and metochalcone were the best, with activity in the micromolar range. These findings represent an opportunity to continue with the research on the potential antifungal application of osalmid and metochalcone as well as the design of structurally related derivatives.

Abstract
Type 2 diabetes (T2D) is one of the most common diseases and the 8th leading cause of death worldwide. Individuals with T2D are at risk for several health complications that reduce their life expectancy and quality of life. Although several drugs for treating T2D are currently available, many of them have reported side effects ranging from mild to severe. In this work, we present the synthesis in a gram-scale as well as the in silico and in vitro activity of two semisynthetic glycyrrhetinic acid (GA) derivatives (namely FC-114 and FC-122) against Protein Tyrosine Phosphatase 1B (PTP1B) and α-glucosidase enzymes. Furthermore, the in vitro cytotoxicity assay on Human Foreskin fibroblast and the in vivo acute oral toxicity was also conducted. The anti-diabetic activity was determined in streptozotocin-induced diabetic rats after oral administration with FC-114 or FC-122. Results showed that both GA derivatives have potent PTP1B inhibitory activity being FC-122, a dual PTP1B/α-glucosidase inhibitor that could increase insulin sensitivity and reduce intestinal glucose absorption. Molecular docking, molecular dynamics, and enzymatic kinetics studies revealed the inhibition mechanism of FC-122 against α-glucosidase. Both GA derivatives were safe and showed better anti-diabetic activity in vivo than the reference drug acarbose. Moreover, FC-114 improves insulin levels while decreasing LDL and total cholesterol levels without decreasing HDL cholesterol.

Abstract
An extract from a PDB static culture of Malbranchea dendritica exhibited α-glucosidase and PTP-1B inhibitory activities. Fractionation of the active extract led to the isolation of gymnoascolide A (1), a γ-butenolide, and xanthones sydowinin A (2), sydowinin B (3), and AGI-B4 (4), as well as orcinol (5). Compound 1 exhibited important inhibitory activity against yeast α-glucosidase (IC50 = 0.556 ± 0.009 mM) in comparison to acarbose (IC50 = 0.403 ± 0.010 mM). Kinetic analysis revealed that 1 is a mixed-type inhibitor. Furthermore, compound 1 significantly reduced the postprandial peak in mice during a sucrose tolerance test at the doses of 5.16 and 10 mg/kg. Compound 1 was reduced with Pd/C to yield a mixture of enantiomers 1a and 1b; the mixture showed similar activity against α-glucosidase (IC50 = 0.396 ± 0.003 mM) and kinetic behavior as the parent compound but might possess better drug-likeness properties according to SwissADME and Osiris Property Explorer tools. Docking analysis with yeast α-glucosidase (pdb: 3A4A) and the C-terminal subunit of human maltase-glucoamylase (pdb: 3TOP) predicted that 1, 1a, and 1b bind to an allosteric site of the enzymes. Compounds 1-5 were evaluated against PTP-1B, but only xanthone 3 moderately inhibited in a noncompetitive fashion the enzyme with an IC50 of 0.081 ± 0.004 mM. This result was consistent with that of docking analysis, which revealed that 3 might bind to an allosteric site of the enzyme. From the inactive barley-based semisolid culture of M. dendritica, the natural pigment erythroglaucin (6) and the nucleosides deoxyadenosine (7), adenosine (8), thymidine (9), and uridine (10) were also isolated and identified.

Abstract
Cancer is the second leading cause of death, after cardiovascular diseases. Different strategies have been developed to treat cancer; however, chemotherapy with cytotoxic agents is still the most widely used treatment approach. Nevertheless, drug resistance to available chemotherapeutic agents is still a serious problem, and the development of new active compounds remains a constant need. Taking advantage of the molecular hybridization approach, in the present work we designed, synthesized, and tested the cytotoxic activity of two hybrid compounds and seven derivatives based on the structure of combretastatin A-4 and 2,3-diphenyl-2H-indazole. Practical modifications of reported synthetic protocols for 2-pheny-2H-indazole and 2,3-dipheny-2H-indazole derivatives under microwave irradiation were implemented. The cytotoxicity assays showed that our designed hybrid compounds possess strong activity, especially compound 5, which resulted even better than the reference drug cisplatin against HeLa and SK-LU-1 cells (IC50 of 0.16 and 6.63 µM, respectively), and it had similar potency to the reference drug imatinib against K562 cells. Additionally, in silico and in vitro studies strongly suggest tubulin as the molecular target for hybrid compound 5.

Abstract
A ligand-based virtual screening study to search for giardicidal compounds on a 6551 ChEMBL drugs database was carried out using molecular similarity. Three fingerprints implemented in MayaChemTools with different design and validated by ROC curves, were used. Twelve compounds were retrieved from this screening, from which, four representative compounds were selected to carry out biological assays. Whereas two compounds were commercially available, the additional two compounds were synthesized during the development of this work. The biological assays revealed that the compounds possess in vitro activity against five strains of Giardia intestinalis, each with different susceptibility/resistance rates to metronidazole, albendazole and nitazoxanide. Particularly, tenatoprazole showed the best effect against the WB and IMSS strains. Furthermore, fabomotizole, tenatoprazole and ipriflavone showed a higher activity against resistant strains than the reference drugs: metronidazole, albendazole and nitazoxanide.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cuphea aequipetala (Lythraceae) is a medicinal plant highly appreciated in Mexico to treat stomach ailments such as pain and burning sensation, stomach infections, ulcers, diarrhea, dysentery, and different types of tumors and bruises. In this work, the infusion of aerial parts of this plant (CAI) was investigated for its polypharmacological potential. MATERIALS AND METHODS In vitro anti-Helicobacter pylori activity was assessed by broth dilution method. Pharmacological studies included acute toxicity in mice using Lorke´s model, anti-inflammatory activity by xylene and TPA induced ear edema assay, as well as gastroprotection with ethanol-induced gastric ulcer model. DPPH and ABTS assays were used to determine antioxidant capacity. Polyphenols and flavonoid contents were determined by Folin-Ciocalteu method and AlCl3 reaction, respectively. RESULTS CAI showed good anti-Helicobacter pylori activity with a MIC of 125μg/mL. The infusion was not toxic according to Lorke's model with a LD50 greater than 5g/kg. CAI exhibited low anti-edematogenic action in the models assayed. Oral administration of 300mg/kg CAI significantly reduced gastric lesions by 87.9%. The effect was reversed only by indomethacin and N-ethylmaleimide demonstrating the role of endogenous prostaglandins and sulfhydryl compounds in gastroprotection. Total phenolic and flavonoid contents of CAI were 109.9mg GAE/g DW and 28.1mg QE/g DW, respectively, and the infusion exhibited a good antioxidant activity that is thought to play a role in its biological activity. The analysis of a preliminary fractionation of the infusion indicates that the complete extract conserves all its pharmacological activities in contrast to fractionated extracts. CONCLUSIONS Cuphea aequipetala is a promising native herb in an integral therapy for the treatment of bacterial or non-bacterial gastric ulcer because it possesses some anti-inflammatory properties, as well as exhibits good gastroprotective and antibacterial effects. It represents an important source for the isolation of anti-Helicobacter pylori compounds. This work provides ethnopharmacological evidence that supports the traditional use of this species.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cyrtocarpa procera Kunth (Anacardiaceae) is a Mexican endemic tree; its bark has been traditionally employed in Mexico since prehispanic times to relieve digestive disorders. AIM OF THE STUDY To perform an acute evaluation of the toxicity, gastroprotective, and anti-inflammatory properties, as well as the anti-Helicobacter pylori action of C. procera bark extracts, in order to determine polypharmalcological activities. MATERIALS AND METHODS Five different polarity extracts (hexanic, CH(2)Cl(2), CH(2)Cl(2)-MeOH, methanolic, and aqueous) were prepared. Each of them was evaluated in the following acute mice models: toxicity Lorke test, ethanol-induced gastric ulcer, TPA-induced ear edema; and the in vitro anti-H. pylori activity with a broth dilution method. RESULTS None of the extracts were toxic under acute administration. The methanolic, hexanic, and aqueous extracts possess remarkable gastroprotective activity. All the extracts inhibit H. pylori growth, being the hexanic the most active, and only this one showed significant anti-inflammatory effect. CONCLUSIONS This work demonstrates that C. procera bark has polypharmacological activities; which makes it a promising asset to the development of an integral treatment for gastritis or peptic ulcer related or not to H. pylori. Our findings contribute to the ethnopharmacological knowledge about this species.

Abstract
Oral administration of a CH(2)Cl(2)-MeOH (1:1) extract of Scaphyglottis livida produced dose-dependent antinociceptive and anti-inflammatory effects when tested in mice and rats using the hot-plate (150-600 mg/kg) and carrageenan-induced inflammation (150-600 mg/kg) models, respectively. Morphine (1.5-6 mg/kg, p.o.) and indomethacin (10-40 mg/kg, p.o.) were used as positive controls, respectively. Four compounds were isolated from the active extract of Scaphyglottis livida, namely 5alpha-lanosta-24,24-dimethyl-9(11),25-dien-3beta-ol (LDD), 24,24,dimethyl-9,19-cyclolanosta-9(11),25-dien-3-one (cyclobalanone), gigantol and 3,4'-dihydroxy-3',4,5-trimethoxybibenzyl (DTB). LDD and gigantol (25-100 mg/kg, p.o.) significantly increased the hot-plate latency in comparison to vehicle-treated mice and decreased carrageenan-induced inflammation in rats. The antinociception provoked by LDD and gigantol was partially blocked by naloxone (1mg/kg, i.p.). However, pretreatment with L-NAME (100 mg/kg, i.p.) and glibenclamide (10 mg/kg, i.p.) did not affect the antinociceptive response induced by LDD or gigantol suggesting that their pharmacological effect could be partially due to activation of opioid receptors. Moreover, a CH(2)Cl(2)-MeOH (1:1) extract of Maxillaria densa reduced acetic acid-induced abdominal writhes but was not able to produce antinociception in the hot-plate assay. Two compounds were isolated from the active extract of Maxillaria densa, namely fimbriol A and erianthridin. Both compounds partially reduced acetic acid-induced writhes. The results tend to support the popular use of this species in folk medicine for treatment of painful complaints.
