Analytical Method Development and Validation of Amlodipine in Human Plasma by using Lc-Ms/Ms

A touchy and precise excessive-overall performance liquid chromatography combined with triple quadrupole mass spectrometry (lc-ms/ms) method, working in the positive ionization mode, for quantifying of Amlodipine in human plasma using Amlodipine maleate d4 as inner widespread (IS) was advanced and confirmed. The analyte and internal standard were extracted by using solid-section extraction with a aggregate of 5 mm ammonium acetate in 0.1% formic acid: methanol: acetonitrile (40: 30: 30%). The Chromatographic separation was performed on zorbax sb, c18, 50* 4.6 mm, 3.5 mm. The analytical approach is legitimate for the estimation of amlodipine, in human plasma over a number 0.100 ng/ml to 9.990 ng/ml with the detection of amlodipine m/z-409.10 (determine) and 238.00 (product) and internal standard amlodipine maleate d4 m/z-413.20 (determine) and 238.00 (product) in positive ion mode. The results of carryover test, matrix impact, linearity, precision and accuracy, stabilities, dilution integrity, run size assessment check provided in this document are inside the popularity range. The robust and rapid lc-ms/ms approach has been efficaciously carried out for ordinary assay to aid bioequivalence or pharmacokinetics studies of amlodipine administered as oral dose to wholesome volunteers.

Synthesis Characterization and Evaluation of Novel Substituted Azole Derivatives

Image
Benzimidazole is a very stable nucleus and the derivatives of 2-methyl benzimidazole may show different and better biological activity. Thepresence of the thiazolidinone ring in a benzimidazole derivative enhances its antimicrobial activity. 2-methyl benzimidazole derivative are formed by the condensation of o-phenylenediamine with acetic acid. Combination of two or more active moieties into one is a common procedure, can result in augmenting the activity and removes untoward side effects. Hence, the present work focuses on synthesis of potent antimicrobial benzimidazole derivatives by the condensation of Schiff's bases of 2-methyl benzimidazole moiety with thiomalic acid affording the thiazolidinone ring and to study their antimicrobial activity. In antibacterial activity (Staphylococcus aureus and Escherichia coli), it shows that compound TE6 is the most active compound and in antifungal activity (Candida albicans), TE3 & TE4 are found to be most active.

Reuse of Treated Wastewater of the City of Salé in Agriculture

Image
The city of Salé produces about 24 millions m3 /year of wastewater. The majority of this water is discharged directly into the Atlantic coast and Bouregreg estuary without any treatment. To preserve the quality of the receiving waters. treating wastewater and reusing it in agricultureproves very interesting. The objective of this study is thus to investigate the treatment and recycling of wastewater in agriculture. We are particularly interested in studying the growth of the stem and the average number of leaves in order to prove the positive effects of reusing treated wastewater in agriculture as compared to untreated wastewater. To achieve this objective. we have investigated the irrigation of the broad bean by three types of water: Untreated wastewater (UW). Well water (WW) and biologically treated wastewater (TW).

Computational Analysis of Physico Chemical Properties of Beta Asarone

Image
The variation in the Physico Chemical properties of Beta Asarone when the temperature is raised is studied here. The Solvent effect has alsobeen calculated with 2 solvents-water and ethanol by (Polarizable continuum Model (PCM) method where a solute cavity is created by a set ofover lapping spheres and computes the energy in solution. The electrostatic interactions of molecules are studied using their Mulliken charge distribution. SCF Energy, Molecular electrostatic Potential mapping, Dipole moment, Ionization Potential and Thermal properties are also studied. Beta Asarone which is the reported toxic constituent of Acorus calamus might undergo variations with higher temperature and also when it is in solution. The study of variations in solution is challenging and here the quantum mechanical calculations are performed in two different solutions to test for any variations of Beta Asarone in solution.
