Microspheres containing Repaglinide was prepared by emulsion solvent evaporation technique using two types of surfactants Tween 80 (polysorbate 80) and Span 80 (Sorbitanmonooleate 80). The effect of change in the type and surfactant amount on the size and drug release from the microspheres was investigated. The release of Repaglinide from the microspheres exhibit diffusional characteristics and closely follows Higuchi Model and also highly correlated with first-order release model. The in-vitro release study was performed in pH 6.8, phosphate buffer Solution and 0.1N HCl. Scanning electron microscopy study revealed that the microspheres were spherical and porous in nature. In vivo testing of the microspheres in diabetic albino rats demonstrated significant antidiabetic effect of Repaglinide. Repaglinide loaded microspheres expected to give new choice for safe, economical formulation for effective management of NIDDM. A clear correlation between the types of surfactant on mean diameter of the microspheres was found. When Span 80 was used, the microspheres were smaller in size as compared to those obtained using Tween 80, while there was a...

Self nano-emulsifying system drug delivery system (SNEDDS) is promising for drugs of BCS class II. The objective of present study to develop self nano-emulsifying drug delivery system for Lipophillic drug Telmisartan (antihypertensive drug), labrafil 1944, Kolliphor ELP: Span 80 (1:1) and PEG 400: Ethanol (1:1) was chosen as oil, Surfactant and Co-surfactant as they show higher solubility for Telmisartan. Screening of Surfactant, Co-surfactant done by percent transmittance and were also observed for turbidity or phase separation visually. Pseudo ternary phase diagram were constructed to identify the self emulsifying regions and also to establish the optimum concentration of oil, surfactant and co-surfactant. Box bhenken desine applied for optimization of formulation. Prepared formulation further Characterization done. Percent Drug Content found 99.71, thermodynamic stability studies show homogenous and no phase separation, Emulsifying Study performed transparent appearance after 24 hr, for robustness Dilutability in water and 0.1N HCl give Percentage Transmittance 99.5 and 100, conducting in vitro dissolution test compared with marketed preparation in stimulated gastric (S.G.F) pH 1.2 showed Percent Drug Release...

2, 6-dithiol-4-methylphenol (DTMP) is proposed as an analytical reagent for the extractive spectrophotometric determination of molybdenum (V). DTMP in the presence 2, 6- bis (N, N-dimethylaminomethyl)-4-methylphenol (AP) forms red colored complex with molybdenum (V) in the pH range 4.8 – 5.8. The Beer’s law was applicable in the range 0.4-22μg mL−1. The dark red Mo-DTMP-AP complex shows a maximum absorbance at 525 nm, with molar absorptivity of 5.21× 104 dm3 mol−1 cm−1 and Sandell’s sensitivity of the complex obtained from Beer’s data is 1.84 ng cm-2. The composition of the Mo (V)-DTMP-AP complex is found to be 1:2:1 (Mo: DTMP: AP). The interference of various cations and anions in the method were studied. The results of the prescribed procedure applied for the determination of the micro amounts of Mo (V) in plant, water and soil samples are...

Context: Ziziphus mistol (mistol) fruits and their derivate product (arrope) have been traditionally used as food and in folk medicine for the treatment of a wide variety of diseases including bronchopulmonary disorder. Objective: The objective of this study is to evaluate the antitussive and expectorant effects of Z. mistol ethanol extract (EE), aqueous extract (AE) and arrope (Ar). Materials and Methods: The antitussive activity was evaluated using two models against ammonia and citric acid induced cough in rats. The expectorant activity was evaluated by volume of phenol red secretion in rats’ tracheas. The tested doses of extracts were of 250, 500 and 1000 mg/kg, (p.o.). Results: The aqueous extract and arrope showed the highest activity in all tested models. The arrope, at 1000 mg / kg, proved to be more effective with inhibitions of 79.69% and 93.75% in the number of coughs induced by ammonium liqueur and citric acid, respectively, while it was similar to codeine. Expectorant activity showed an 87.73% increase in red phenol secretion at the same dose,...

NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) is a protein complex that controls transcription of DNA, cytokine production and cell survival. Incorrect regulation of NF-κB has been linked to cancer, inflammatory and autoimmune diseases and improper immune development. The main objective of the present research work was the synthesis of N-(4-{[5-(substituted phenyl)-1,3,4-oxadiazol-2-yl] methoxy}phenyl) acetamide derivatives and to evaluate the hepatocytes regenerator potentiality by molecular docking with 2V2T-NF-KB and as well as In vivo methods and the synthesized compounds were characterized by IR, NMR, and Mass spectroscopy. The in-vivo Hepatoprotective activity was carried out by using albino rats where CCl4 was used as a hepatotoxin. Molecular docking is performed to find out the binding affinity or molecular interaction energy (kcal/mol) of docked compounds. In silico molecular docking studies displayed the binding energies: -5.17, -5.52, -5.40, -4.60, -4.60, -4.87, -3.42, -3.85 k.cal/mol, of the synthesized compounds (AB1-AB8) which indicated that the compound had the high binding affinity towards the 2V2T-NF-KB protein and inhibit the NF-KB protein function in comparison with...
