Sumatriptan has been used for the acute treatment of migraine attacks. There are many similarities between migraine and epilepsy and the medications used to treat one of these disorders can effectively be used to treat the other. The purpose of this study was to evaluate and compare the anticonvulsant effects of sumatriptan with sodium valproate in NMRI mice. 62 male NMRI mice were divided into 8 groups. The groups consisted of a saline (control) group, 4 intraperitoneally (ip) administered sumatriptan groups (1, 10, 50, and 100 mg/kg, ip), and 3 sodium valproate groups (50, 150, and 300 mg/kg, ip)...

Pyridazines, their oxo derivatives; pyridazinone as well as fused bi- or tricyclic pyridazine containing scaffolds are key structural features of many biologically active compounds with diverse pharmacological applications, including cancer therapy. Since protein kinases play prominent role in tumor biology, the inhibition of its signaling pathway is considered an effective therapeutic option for the treatment of cancer.Based on the various advantages of pyridazines in drug design including modulation of the physico-chemical properties, improving ADME and toxicity profile as well as easy and diverse synthetic methods of access, makes them an invaluable tool for designing compounds as future drugs for targeted cancer treatment...

Chemical substances have an important threat due to extensive use in medicine, agriculture, industry and environment. In this retrospective study, etiological and demographic characteristics of acute poisoning cases admitted to a hospital in Iran were investigated. We compared these data with those reported from other parts of the country and the international experiences to evaluate any difference if exists. 7 052 poisoned cases admitted to the hospital from April 2006 to March 2013, by data collected from the medical record in poison center section...

Isradipine (ID), is an antihypertensive drug, having low oral bioavailability (15-24%) due to poor aqueous solubility (0.01 mg/mL) and also hepatic first-pass metabolism. Among various approaches, Solid lipid nanoparticles (SLNs) were developed using stearic acid, glyceryl monostearate as lipid matrices for improving the oral bioavailability of ID. ID-SLNs were prepared by using hot homogenization followed by ultrasonication. The prepared SLNs were characterized for size, PDI, zeta potential (ZP), entrapment efficiency (EE) and drug content...

Silent information regulator 2 homologue one (SIRT1) modulators have therapeutic potential for a number of diseases like cardiovascular, metabolic, inflammatory and age related disorders. Here, we have studied both activators and inhibitors of SIRT1 and constructed differential quantitative structure activity relationship (QSAR) models using CORAL software by Monte Carlo optimization method and SMILES notation. 3 splits divided into 3 subsets: sub-training, calibration and test sets, were examined and validated with a prediction set...

Chlorambucil (CBL) is an alkylating agent, which widely use in the treatment of various types of tumors. The main purpose of this study is to evaluate the in-vivo biodistribution of CBL conjugated to the anionic dendrimer, which has a great ability to labeled with (99m)Tc through binding to carboxylate terminate groups. Whole body scans were used to analyze the percentage of the injected dose in different times. Radiochemical purity (RCP) and in-vivo biodistribution were also calculated with the SPECT/CT instrument...

Purpose Monoamine oxidase (MAO) inhibitors are considered to be useful therapeutic agents and isoform specific inhibitors are employed for the treatment of depression and Parkinson's disease. MAO inhibitors are also under investigation for the treatment of disorders ranging from Alzheimer's disease, prostate cancer and certain cardiomyopathies. While a number of irreversible MAO inhibitors are available in the clinic, reversible inhibitors, particularly of the MAO-B isoform are still being developed. Based on our interest in discovering reversible inhibitors with specificity for MAO-B, we have recently reported that, among a series of 10 3,4-dihydro-2(1H)-quinolinone derivatives, are high potency MAO-B inhibitors, with a number of homologues displaying good selectivities for MAO-B over the MAO-A isoform...

Phase I, randomized, controlled patch studies were conducted to evaluate skin sensitization and irritation potential of a new gel formulation containing 1% diclofenac and 3% menthol as a fixed-combination product.In study A, healthy volunteers were exposed to 4 test patches containing 1% diclofenac+3% menthol, diclofenac, menthol, or placebo gels during an induction (nine 48 to 72-h applications) and challenge phase (one 48-h application). Some subjects were re-challenged to evaluate suspected sensitization...

Gold nanoparticles (AuNPs) due to their unique properties and manifold surface functionalities have been applied in bio-nanotechnology. The application of GNPs in recent medical and biological research is very extensive. Especially it involves applications such as detection and photothermalysis of microorganisms and cancer stem cells, biosensors; optical bio-imaging and observing of cells and these nanostructures also serve as practical platforms for therapeutic agents. In this review we studied all therapeutic applications of gold nanoparticles in biomedicine, synthesis methods, and surface properties...

The antimicrobial property of silver is associated to the quantity of silver and the grade of silver released. The ionized silver is extremely sensitive, as it binds to tissue proteins and gets operational alterations in the bacterial cell wall and nuclear membrane leading to cell modification and death.Silver nanoparticles have the talent to anchor to the bacterial cell wall and consequently infiltrate it, so causing physical modifications in the cell membrane like the absorptivity of the cell membrane and death of the cell...

Background:Helicobacter pylori is a prevalent pathogen which is considered as an etiological cause for gastroduodenal ulcers, and a substantial risk factor for gastric malignancies. The vital factor to take into account is that roughly half of the world's population is infected with this bacterium. However, most subjects colonized remain asymptomatic and do not require any treatment. Several antimicrobial agents such as amoxicillin, clarithromycin and metronidazole are used to eradicate the infection. However, these drug regiments do not eradicate H...

Purpose: Relatively little is known about gender-dependent susceptibility to hepatic injury induced by nutritional factors. In the current study, we investigated dietary fructose-induced hepatic degeneration and roles of endothelial nitric oxide synthase (eNOS), insulin receptor (IRβ) and substrate-1 (IRS-1) expressions in association with inflammatory markers in male and female rats. Moreover, we examined potential effect of resveratrol on fructose-induced changes. Methods: Male and female rats were divided into 4 groups as control, resveratrol, fructose and resveratrol plus fructose...

Using a click chemistry approach, a series of gallic-acid-1-phenyl-1H-[1,2,3]triazol-4-ylmethyl esters was synthesized to develop more effective antioxidants. The results of DPPH screening indicate that few of the synthesized analogs display better antioxidant effect compared to the standards. Among all, compounds, 9 and 20 displayed highest DPPH radical scavenging effect with IC50 values as low as 6.4±0.2 and 7.9±0.4 µM respectively, compared to the standard ascorbic acid (IC50=12±0.8 µM) and gallic acid (IC50=9...

A sensitive, specific and reproducible liquid chromatography coupled to tandem mass spectrometric method was developed and validated for the estimation of ciprofloxacin, an extensively used second-generation quinolone antibiotics, in human plasma. A liquid-liquid extraction of ciprofloxacin and the internal standard, ofloxacin, has been approached from the biological matrix using chloroform. Chromatographic separation was achieved in positive ion modes, isocratically on a 3.5 μm C18 analytical column (75 mm×4...

The skin is fortified with a setup of lipophilic and hydrophilic, enzymatic and non-enzymatic antioxidant systems. Ascorbyl palmitate (AP) and sodium ascorbyl phosphate (SAP) are reported as lipophilic and hydrophilic antioxidants, respectively used for skin care. Present study was aimed to assess the combined AP (in oil phase) and SAP (in aqueous phase) via multiple emulsion (ME1) for controlling sebum secretions in healthy human females. FTIR analysis of AP and SAP was performed for identification. Multiple emulsions (ME1 and control) were prepared and analyzed for physical stability...
