Optimized microwave-assisted extraction of polyphenols and tannins from Syzygium cumini (L.) Skeels leaves through an experimental design coupled to a desirability approach.

The present study consisted in optimizing the extractive method of polyphenols and total tannins of leaves of Syzygium cumini (L) Skeels assisted by microwaves to potentiate the antimicrobial activity of the dried extract of S. cumini against sensitive and resistant strains. A Box-Behnken design that consisted of 27 experimental runs coupled with a desirability function for multiple response optimization was employed to optimize the total polyphenols content and total tannins content. Antimicrobial sensitivity tests were evaluated by obtaining the minimum inhibitory concentration, minimum fungicidal concentration and minimum bactericidal concentration in 96-well petri dishes. The optimal extraction conditions were found to be 8 min of extraction, under 300 w of microwave power, using a 1:34 g/mL solid/solvent ratio and 38% of ethanol concentration as extraction solvent. The parameter with the greatest influence in the extraction was primarily the time, followed by the potency and proportion solid/solvent. This yielded a total polyphenol content of 87.37 ± 1.85 mg TAE g-1ext and a total tannin content of 79.68 ± 1.64 mg TAE g-1 ext. All tested microorganisms were sensitive to the extract, evidencing the effectiveness of the extraction method optimization.

Development of an analytical method for determination of polyphenols and total tannins from leaves of Syzygium cumini L. Skeels.

Syzygium cumini L. Skeels belongs to Myrtaceae family. This species has been recognized by its antidiabetic, anti-inflammatory, and antimicrobial activities. Despite ever-increasing scientific interest for this species there is no pharmacopeia method for characterization and standardization of S. cumini yet. So, toward this aim, the objective of this work was to develop an efficient analytical methodology able to determine polyphenols and tannins content from leaves hydroethanolic extract of S. cumini using Folin-Ciocalteu method by ultraviolet absorption spectrophotometry (UV-Vis). The analytical methodology was developed for the first time in the literature for leaves of this specie shown to be fast and low-cost with results expressed through tannic acid equivalent (TAE). Moreover, the methodology presented selectivity with maximum absorption at 706 nm wavelength, linearity with R2>0.99; limit of detection 0.275 µg TAE mL-1 and 0.102 µg TAE mL-1; limit of quantification 1.046 µg TAE mL-1 and 0.912 µg TAE mL-1 for total polyphenols and total tannins, respectively. Furthermore, the methodology was accurate with recover value greater than 98%, as well as exact, reproductive, and robust with coefficient of variation values less than 15% for both compounds. All the results are found within the fixed limits according to RDC 166/2017.

ß-Cyclodextrin complex improves the bioavailability and antitumor potential of cirsiliol, a flavone isolated from Leonotis nepetifolia (Lamiaceae).

Cirsiliol is a flavone found in many Lamiaceae species with high cytotoxic activity against tumor cell lines. Although cirsiliol is being used in cancer therapy, its pharmacological potential is limited by its low solubility and bioavailability. In this paper, a cirsiliol-ß-cyclodextrin inclusion complex was developed in order to increase its solubility and bioavailability. The formation of inclusion complex was proved by scanning electron microscopy, Fourier-transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) and solubility increment was verified through the ultraviolet-visible (UV-Vis) method. The cytotoxic effect against tumor cells (PC3, HCT-116 and HL-60 human cell lines, and S-180 murine cell line) and the antitumor activity in mice bearing sarcoma S-180 were also investigated. The inclusion complex was obtained with 71.45% of total recovery and solubility 2.1 times higher compared to the compound in its free form. This increment in solubility was responsible by a tumor growth inhibition potentiation (1.5 times greater compared to compound in its free form). In addition, this study showed that cirsiliol and its inclusion complex in ß-cyclodextrin have strong antitumor potential at low doses without promoting side effects commonly observed for conventional drugs as doxorubicin.

Solid dispersions to enhance the delivery of a potential drug candidate LPSF/FZ4 for the treatment of schistosomiasis.

Drug candidate LPSF/FZ4 with promising schistosomicidal properties in vitro was previously synthesized. However, LPSF/FZ4 has limited aqueous solubility (<1 µg/mL), leading to ineffective dissolution and, therefore, no meaningful in vivo comparative studies could be pursued. This study was aimed to develop a proper amorphous solid dispersion (SD) to enhance the solubility and dissolution rate of LPSF/FZ4 such that its biological activity could be investigated. To better understand its physiological behavior, the pKa of LPSF/FZ4, a monoprotic weak acid with NH group at the imidazolidine ring, was first determined to be 8.13 using an automated SiriusT3. The development of SD systems for LPSF/FZ4 involved the evaluation of various water-soluble polymer carriers such as PVP K-29/32, PVP K-90, HPMC K4M, PVPVA 64 and SOLUPLUS®. The most promising SD systems were selected through in vitro dissolution studies under nonsink conditions, together with physicochemical characterization as well as accelerated stability study. It was shown that SD of 10% LPSF/FZ4 in SOLUPLUS® and PVP K-90 could significantly increase the area-under-the-curve value of the nonsink dissolution profile (AUC values of the SD in SOLUPLUS® and PVP K-90 were 1381.03 and 1342.34 µL/mL·min, respectively, and that of the pure crystalline drug was 0.02 µL/mL·min), a useful surrogate for the in vivo bioavailability. Cmax values for the SD in SOLUPLUS® (12.50 µL/mL) and PVP K-90 (25.86 µL/mL) were also higher than the one of the crystalline drug (0.02 µL/mL). The SD system of LPSF/FZ4 in SOLUPLUS® showed a significant increase in schistosomicidal activity in an animal model as compared with the conventional treatment using crystalline drug, consistent with the AUC trend from the nonsink dissolution. Thus this SD system of LPSF/FZ4 could be useful as a potential formulation for treating schistosomiasis.

Evaluation of anti-inflammatory potential of aqueous extract and polysaccharide fraction of Thuja occidentalis Linn. in mice.

Inflammation is a protective reaction of the microcirculation. However, sustained inflammation can lead to undesired effects. Thuja occidentalis Linn has many pharmacological properties but has no anti-inflammatory activity described. Thus, this study aims evaluating the anti-inflammatory activity of the aqueous extract (AE) and the polysaccharide fraction (PLS) of T. occidentalis L. in mice. The results of our evaluations in various experimental models indicated that AE and PLS (3, 10, and 30mg/kg, i.p.) reduced (p˂0.05) paw edema induced by carrageenan, dextran sulfate (DEX), compound 48/80, serotonin (5-HT), bradykinin (BK), histamine (HIST), and prostaglandin E2 (PGE2). Furthermore, it inhibited neutrophils recruitment; decreased MPO activity, tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) levels, vascular permeability, nitrite concentration, and MDA concentration; and maintained the GSH levels in the peritoneal exudate. The AE and PLS reduced neutrophil infiltration and cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) immunostaining in paw tissue. Treatment with the AE and PLS (300mg/kg) did not induce gastric toxicity. In conclusion, these results show that the AE and PLS reduced the inflammatory response by inhibiting vascular and cellular events, inhibiting pro-inflammatory cytokine production, and reducing oxidative stress. Furthermore, they did not induce gastric toxicity at high doses.

Theoretical and experimental studies of the stability of drug-drug interact.

Several factors can intervene in the molecular properties and consequently in the stability of drugs. The molecular complexes formation often occur due to favor the formation of hydrogen bonds, leading the system to configuration more energy stable. This work we aim to investigate through theoretical and experimental methods the relation between stability and properties of molecular complexes the molecular complex formed between the drugs, efavirenz (EFV), lamivudine (3TC) and zidovudine (AZT). With this study was possible determining the most stable complex formed between the compounds evaluated. In addition the energy and structural properties of the complex formed in relation to its individual components allowed us to evaluate the stability of the same.

Induction of cancer cell death by apoptosis and slow release of 5-fluoracil from metal-organic frameworks Cu-BTC.

This study aimed to evaluate the mechanism associated with cytotoxic activity displayed by the drug 5-fluorouracil incorporated in Cu-BTC MOF and its slow delivery from the Cu-BTC MOF. Structural characterization encompasses elemental analysis (CHNS), differential scanning calorimetry (DSC), thermogravimetric analysis (TG/DTG), Fournier transform infrared (FIT-IR) and X-ray diffraction (XRD) was performed to verify the process of association between the drug 5-FU and Cu-BTC MOF. Flow cytometry was done to indicate that apoptosis is the mechanism responsible for the cell death. The release profile of the drug 5-FU from Cu-BTC MOF for 48 hours was obeisant. Also, the anti-inflammatory activity was evaluated by the peritonitis testing and the production of nitric oxide and pro-inflammatory cytokines were measured. The chemical characterization of the material indicated the presence of drug associated with the coordination network in a proportion of 0.82 g 5-FU per 1.0 g of Cu-BTC MOF. The cytotoxic tests were carried out against four cell lines: NCI-H292, MCF-7, HT29 and HL60. The Cu-BTC MOF associated drug was extremely cytotoxic against the human breast cancer adenocarcinoma (MCF-7) cell line and against human acute promyelocytic leukemia cells (HL60), cancer cells were killed by apoptosis mechanisms. The drug demonstrated a slow release profile where 82% of the drug was released in 48 hours. The results indicated that the drug incorporated in Cu-BTC MOF decreased significantly the number of leukocytes in the peritoneal cavity of rodents as well as reduced levels of cytokines and nitric oxide production.

Anti-inflammatory and anti-arthritic activities of 3,4-dihydro-2,2-dimethyl-2H-naphthol[1,2-b]pyran-5,6-dione (ß-lapachone).

OBJECTIVE AND DESIGN: The purpose of this study was to evaluate the anti-inflammatory and anti-arthritic activities of 3,4-dihydro-2,2-dimethyl-2H-naphthol[1,2-b]pyran-5,6-dione (ß-lapachone; ß-lap) and to elucidate its probable mode of action. METHODS: Carrageenan-induced paw edema, cell migration evaluation and production of pro-inflammatory cytokines tumor necrosis factor (TNF)-α, interleukin (IL)-6 and nitric oxide were used for this study. Freund's complete adjuvant (FCA)-induced arthritis was used as a model of chronic inflammation. ß-Lap was tested in doses of 40 and 60 mg/kg, orally. RESULTS: In the paw edema test, the dose of 60 mg/kg gave a higher percentage inhibition of edema (49.3 %) than control. ß-Lap inhibited neutrophil migration and reduced concentrations of TNF-α, IL-6 and NO in peritoneal exudates of animals with peritonitis. In the arthritis test, ß-lap inhibited edema and NO production in the serum of treated animals. CONCLUSION: Significant anti-inflammatory and anti-arthritic activities were observed in animals treated with ß-lap. The effects of ß-lap can be attributed in part to immunomodulation with reduction of pro-inflammatory cytokines and NO.

Benznidazole drug delivery by binary and multicomponent inclusion complexes using cyclodextrins and polymers.

Benznidazole (BNZ) is the drug of choice for Chagas disease treatment, which affects about 9.8 million people worldwide. It has low solubility and high toxicity. The present study aimed to develop and characterize inclusion complexes (IC) in binary systems (BS) with BNZ and randomly methylated-ß-cyclodextrin (RMßCD) and in ternary systems (TS) with BNZ, RMßCD and hydrophilic polymers. The results showed that the solid BS had a large increase in dissolution rate (Q>80%). For the solid IC obtained, the kneading method, in ratio of 1:0.17 (77.8% in 60 min), appeared to be the most suitable for the development of a solid oral pharmaceutical product, with possible industrial scale-up and low concentration of CD. The solid TS containing 0.1% of hydroxypropylmethylcellulose (HPMC) showed no significant advantages compared to the binary IC in solid state. The use of cyclodextrins proved to be a viable tool for effective, standardized and safe drug delivery.

The use of solid dispersion systems in hydrophilic carriers to increase benzonidazole solubility.

The present study investigates the release mechanism of benznidazole (BNZ) in solid dispersions with polyethylene glycol 6000 (PEG 6000) and polyvinylpirrolydone K-30 (PVP K-30), with a view to observing the increase in solubility of BNZ in water in the presence of these two hydrophilic polymers. The interaction of BNZ with the polymers was evaluated using scanning electron microscopy, Fourier-transformation infrared spectroscopy, differential scanning calorimetry, X-ray diffraction, and in vitro dissolution tests, and a theoretical study of molecular modeling was also carried out. The drug-polymer interaction was studied trough molecular modeling, using density functional theory with the B3LYP exchange correlation function. The corrected interaction energies were calculated to be -20.9 kJ/mol with PVP and -6.6 kJ/mol with PEG. The experimental and theoretical results indicate that a powerful interaction occurred between BNZ and the polymers, which was especially strong in the case of PVP, and that this interaction contributed to improvement of BNZ solubility.

Development of a Bacillus sphaericus tablet formulation and its evaluation as a larvicide in the biological control of Culex quinquefasciatus.

This study aimed to analyze the final fermentation culture of Bacillus sphaericus 2362, standardize it and develop an active tablet formulation for use in urban mosquito breeding sites. It was performed in three phases: analysis and standardization of a B. sphaericus fermented culture; physical, chemical, and biological analysis of the active powder (solubility, residual humidity, particle size, resting angle, flowing off time, compacted density, and biological activity against Culex quinquefasciatus larvae); and the development of fast-disintegrating tablets. Five formulations with differing compositions were developed and a UV protector was added to the selected formulation. The formulation products with or without UV protector, as well as the active powder caused 100% larval mortality from 1 day to 2 months after a single treatment under simulated field conditions. These results show that the UV protector does not affect the initial larvicide activity of B. sphaericus, nor its persistence over a period of two months.
