[ 6 ] - Pharmacokinetics and Bioequivalence study of Two Formulations of Cefixime in Healthy Male Volunteers

Cefixime is a significant member of orally active third generation cephalosporin and has excellent activity against many pathogens. The virtual bioavailability of a newly industrial dispersible tablet as compared with a recognized identified formulation. An open-label, single-dose, randomized, 2-way crossover study was conducted in fasted healthy Iranian male volunteers. Eligible participa...

[ 7 ] - Simple and sensitive high performance liquid chromatographic (HPLC) method for the determination of the apigenin from dried powder of Cosmos bipinnatus, Apium graveolens and Petroselinum crispum

Apigenin is best known as an irreversible inhibitor of monoamine oxidase (MAO), an intracellular enzyme associated with the outer membrane of mitochondria. The purpose of this study is to establish a reliable and quick method for the assignment of Apigenin in Cosmos bipinnatus, Apium graveolens and Petroselinum crispum by high performance liquid chromatography with ultraviolet detection (HPLC-U...

[ 8 ] - A quick and Sensitive Liquid Chromatography–tandem Mass Spectrometry (LC-MS) Method for the Determination of Enalapril and Enalaprilat in Human Plasma: Application to a Bioequivalence Study

A rapid and sensitive liquid chromatography–tandem mass spectrometry (LC-MS) method for the estimation of enalapril and enalaprilat in human plasma. Detection of analytes was achieved by tandem mass spectrometry with electrospray ionization (ESI) interface in positive ion mode was operated under the multiple-reaction monitoring mode. Sample pretreatment involved in a one-step protein precipitat...

[ 9 ] - The Hypoglycemic Effects of an Ethanol Extract of Peganum harmala in Streptozotocin-Induced Diabetic Rats

Peganum harmala is a plant that is traditionally used as an analgesic, anti-inflammatory, antibacterial, antioxidant, anti-helmintic, and antimutagenic agent. Moreover, it is used to treat a variety of human ailments, including depression. This study was conducted to investigate the antidiabetic activity of hydro alcoholic extract of this herb. A hydro alcoholic extract from seeds of this herb ...

[ 10 ] - Synthesis and characterization of mPEG-PCL copolymers as a polymersomes for delivery of enalapril as a model hydrophilic drug

Purpose: Enalapril maleate (EPM), was used for hypertension and congestive heart failure. In this way, an innovative delivery system with mPEG–PCL was synthesized and the release profile of the EPM from the drug-loaded polymersomes was evaluated. Methods: Di-block methoxy)-poly (ethylene glycol) - Poly (caprolactone) (mPEG-PCL) copolymers were synthesized and used to prepare of polymersom...

[ 11 ] - Cell Suspension Culture of Plumbago europaea L. Towards Production of Plumbagin

Background: Plumbagin is as an important bioactive secondary metabolite found in the roots of Plumbago spp. The only one species, Plumbago europaea L., grows wild in Iran. The therapeutic use of plumbagin is limited due to its insufficient supply from the natural sources as the plants grow slowly and take several years to produce quality roots. O...
