RESUMO

OBJECTIVE: The present study was taken up to evaluate the combination of two drugs in the management of behavioral disorders such as locomotor activity, muscle relaxation, analgesic, and anxiolytic activity. MATERIALS AND METHODS: In the methodology, Wistar rats weighing (150-180 g) were divided into six groups of 6 each (n=6). All the animals (groups II to VI) were subjected to stress and analyzed for anxiolytic activity using an elevated plus maze. The animals were treated for 28 days with poppy seed oil in lower and higher doses (1,000 and 2,000 mg/kg), tramadol in lower and higher doses (1.5 and 3 mg/kg) as individual groups, and one group with a combination of both drugs in lower doses. RESULTS: The results depicted showed that the combined treatment had significantly (**p <0.001) improvised behavior deficits, extemporized, and diminished anxiety-like attitude in rats, and showed the analgesic property in a significant manner. The pro-inflammatory cytokines TNF-α and IL-1ß were evaluated in the serum and were observed to be lessened the values of both in a significant manner with the co-administration of both the test drugs. The dopamine concentrations were also determined in the serum, which disclosed a decline (**p <0.001) significantly. CONCLUSIONS: It was concluded from the results that a combined effect of drugs might be beneficial in the management of behavioral disorders and pain management.

RESUMO

The present work was designed to investigate the presence of bioactive chemicals in the reaction mixtures (RMs) of peels of Valencia, Mandarin, and African navel oranges, through GC-MS and FT-IR studies. Limonene, a unique compound, is present in the RMs of the three orange peels. Moreover, hexadecanoic acid 2-hydroxy-1-(hydroxymethyl) ethyl ester was identified in the RMs of all the three-orange peels. The RM of Mandarin orange exhibited potent cytotoxic effect against MCF-7 ATCC human breast cancer cells (HBC). All the three RMs exhibited moderate antibacterial activity against the human pathogenic bacteria Staphylococcus aureus (ATCC 25923), Staphylococcus epidermidis (ATCC 12228), Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25922), Klebsiella pneumoniae (ATCC 700603), Salmonella choleraesis (ATCC 10708), Pseudomonas aeruginosa (ATCC 27853), and Proteus mirabilis (ATCC 299).

RESUMO

Abstract The objective of the present study was to analyse the bioactive compounds of the leaves of Conocarpus lancifolius (C. lancifolius). The GC-MS analysis of the hot methanolic extract of the leaves (HMEL) of C. lancifolius exhibited the bioactive compounds such as 1-(3-Methoxy-2-nitrobenzyl) iso quinoline, morphin-4-ol-6,7-dione, 1-bromo-N-methyl-, phytol, hexadecanoic acid, 2,3-dihydroxypropyl ester, 2,2':4',2"-terthiophene, ethyl iso-allocholate, caryophyllene oxide, campesterol, epiglobulol, cholestan-3-ol, 2-methylene-, (3á,5à)-, dasycarpidan-1-methanol, acetate (ester) and oleic acid, eicosyl ester. The FT-IR analysis of HMEL of C. lancifolius showed a unique peak at 3184, 2413, 1657 cm-1 representing coumaric acid, chlorogenic acid and ferulic acid. The HMEL of C. lancifolius was actively inhibiting the proliferation of breast cancer cells MCF-7 ATCC at the concentration of 72.66 ± 8.21 µg/ml as IC50 value. The HMEL of C. lancifolius also revealed a good spectrum of activity against Gram-positive and Gram-negative bacterial cultures screened in this work. The activity observed has shown more or less similar effects against screened bacteria. However, the magnitude of potentiality was significantly lesser compared to standard ciprofloxacin disc at p< 0.001 level (99% confidence intervals). Furthermore, the study demonstrating the bioactive compounds can be isolated from the leaves of C. lancifolius.

RESUMO

Serum levels of the inflammatory C-X-C motif chemokine 10 (CXCL10) are raised in tuberculosis (TB). CXCL10 gene expression is downregulated in monocytes by metabolically active vitamin D3 (1,25dihydroxy vitamin D). Stratification of patients by serum 25hydroxyvitamin D (25[OH]D) levels at baseline showed that treatment-induced decrease in CXCL10 occurred in those with 'insufficient' and 'deficient' but not in those with 'optimal' levels. In the deficient group, 25(OH)D showed an inverse correlation with CXCL10 levels. CXCL10 may thus be a useful biomarker for the follow-up of response to treatment. However, CXCL10 levels should be interpreted taking into account the baseline serum vitamin D levels of the TB patients.

RESUMO

Zafirlukast is a selective leukotriene receptor antagonist used for the prophylaxis and chronic treatment of asthma. The aim of the present study was to develop a simple sensitive ultra-performance liquid chromatography tandem mass spectroscopy method for rapid determination of zafirlukast in plasma. After a simple one step protein precipitation by acetonitrile, zafirlukast and montelukast (IS) were separated on Acquity UPLC BEH(TM) C18 column (50 × 2.1 mm, i.d. 1.7 µm, Waters, USA) using a mobile phase of acetonitrile:water containing 10 mM acetic acid (80:20, v/v) at a flow rate of 0.3 mL/min. Zafirlukast and IS were eluted at 0.51 and 1.1 min, respectively with a total run time of only 1.5 min. The mass spectrometric determination was carried out using an electrospray interface operated in the negative mode with multiple reactions monitoring mode. The precursor to product ion transitions of m/z 574.11>462.07 and m/z 584.2>472.1 were used to quantify zafirlukast and IS, respectively. The method was linear in the concentration range of 0.17-600 ng/mL with coefficients of determination greater than 0.996 and lower limit of quantitation of 0.17 ng/mL. Intra-day and inter-day accuracies were 88.3-113.9% and the precisions were ≤ 12.6%. Zafirlukast was found to stable under various storage and sample processing conditions as per guidelines of bio-analytical method validation. The method developed herein is simple and rapid, and was successfully applied for the pharmacokinetic study in rabbits.

RESUMO

A series of 3-arylidene-5-(4-chloro-phenyl)-2(3H)-furanones (2-13) and their nitrogen analogues 1-benzylpyrrolones (14-18) were synthesized. The compounds were evaluated for their anti-inflammatory, analgesic, ulcerogenic and lipid peroxidation actions. Some of the newly synthesized compounds showed good anti-inflammatory and analgesic activities with low GI toxicity and reduced lipid peroxidation. The biological activity was found to improve upon replacement of oxygen of furanone ring with benzylamine moiety i.e. 1-benzylpyrrolones. Similarly, compounds containing halogen group(s), compounds 15 and 17, showed higher degree of anti-inflammatory activity and their activity was comparable to that of the standard. These compounds showed interesting profile of analgesic activity in acetic acid induced writhing test (peripheral effect) and in the hot-plate test (central effect). The compounds were also tested for their ulcerogenic and lipid peroxidation action and showed superior GI safety profile along with reduction in lipid peroxidation as compared to that of the standard.
