Design and Synthesis of Mannich bases as Benzimidazole Derivatives as Analgesic Agents
Mannich bases were selected for 2D QSAR study to derive meaningful relationship between the structural features and analgesic activity. Using the knowledge of important features a novel series was designed to obtain improved analgesic activity. A series of novel Mannich bases 1-(N-substituted amino)
A Derivative Method with Free Radical Oxidation to Predict Resveratrol Metabolites by Tandem Mass Spectrometry
In this study, we demonstrated an oxidative method with free radical to generate 3,5,4 -trihydroxy-transstilbene (trans-resveratrol) metabolites and detect sequentially by an autosampler coupling with liquid chromatography electrospray ionization tandem mass spectrometer (LC-ESI–MS/MS). In this ox
A Simple and Sensitive Hydrazine Electrochemical Sensor Based on Platinum Nanoclusters
In this paper, platinum nanoclusters (PtNCs) were synthesized by less sophisticated equipments with low cost and tedious procedures, and then applied to construct a simple electrochemical hydrazine sensor rapidly within the applied potential. PtNCs were proved to have advantages over platinum nanopa
Emerging Antimicrobial Applications of Nitric Oxide (NO) and NO-Releasing Materials
During the past few decades, the potential of treating infections with nitric oxide (NO) has been firmly demonstrated in various laboratories. Both in vitro and in vivo studies have afforded promising results in terms of reducing microbial loads in chronic wounds in addition to its utility in keepin
Design, Synthesis, and Evaluation of Genistein Analogues as Anti-Cancer Agents
Genistein is a bioactive isoflavone derived from soybeans. The tie-in between the intake of genistein and the decreased incidence of some solid tumors (including prostate cancer) has been demonstrated by epidemiological studies. The potential of genistein in treating prostate cancer has also been di
Development of Montelukast Sodium Loaded Niosomal Carriers by Film Hydration Technique
The aim of this study was to develop and characterize montelukast sodium loaded niosomal drug carrier systems. The vesicles were prepared by film hydration technique using different surfactants. The optimized formulation was selected on the basis of results obtained from drug entrapment, morphology
Effects of CAP-regimen Chemotherapy on Blood Redox Status in Patients with Ovarian Cancer
Background: Ovarian cancer (OC) is the most lethal of gynecologic tumors because women generally present with advanced stage disease. Platinum-based chemotherapy play a pivotal role in OC treatment. The aim of the study was to assess the effects of CAP-regimen chemotherapy on blood redox status in p
Determination of Carprofen in the Presence of some Hydrosoluble Vitamins of Group B by HPLC Method
A new HPLC method have been developed and validated for simultaneous determination of carprofen, vitamin B1, B6 and B12 in veterinary pharmaceutical preparations medicines. The method used a Hypersil GOLD aQ (250 x 4.6 mm, 5 µm) column, under the following chromatographic conditions: gradient e
Synthesis of Isoxazole Moiety Containing Thieno[2,3-d]pyrimidine Derivatives and Preliminarily in vitro Anticancer Activity (Part II)
21 new structures of isoxazole-moiety-containing thieno[2,3-d]pyrimidine derivatives(3a~3u) were synthesized for the first time and characterized using IR, 1H NMR, 13C NMR, ESI-MS and elemental analysis techniques. And then their in vitro anticancer activity against lung cancer A549, colorectal HCT1
A Novel Multi-functional Fluorescent Probe for Cu2+, Fe3+ and Ag+ Based on a Pyrimidine Thiourea Derivative
A multi-functional “turn-off” fluorescent probe, N-[[(6-Amino-1,2,3,4-tetrahydro-1,3- dimethyl-2,4-dioxo-5-pyrimidinyl)amino]thioxomethyl]- benzamide, was synthesized and characterized. The probe showed high sensitivity and selectivity towards copper(II), iron(III) and silver(I) ions via quenchi
Anti-Inflammatory Activity of Polysaccharide Fraction of Curcuma longa Extract (NR-INF-02)
The aim of the study was to investigate the safety and anti-inflammatory effects of polysaccharide fraction (F1) of Curcuma longa extract (NR-INF-02) in classical rodent models of inflammation. F1 was evaluated for its acute oral toxicity and found to be safe upto 5000 mg/kg body weight in rats. The
Quercetin Increase the Chemosensitivity of Breast Cancer Cells to Doxorubicin Via PTEN/Akt Pathway
Our previous study indicated that nontoxic doses of quercetin (Que) could increase the chemosensitivity of breast cancer cells to doxorubicin (Dox) although the mechanism still remains elusive. Therefore, in this study, we aimed to investigate the underlying mechanisms. MCF-7 cells and MCF-7/dox cel
Induction and Escalation Therapies in Multiple Sclerosis
Multiple sclerosis (MS) is a chronic demyelinating disease affecting the central nervous system. Pharmacological therapy of MS includes symptomatic drugs, treatment for relapses (corticosteroid and intravenous immunoglobulin) and disease modifying drugs (DMDs) defined as pharmacological agents that
