The aim of the current investigation was Kinetic and mechanistic study of donepezil hydrochloride by sodium-N-chloro-p-tolunesulfonamide or chloramine-T (CAT) in NaOH medium was studied at 308 K. the re...
STUDY OF CLINICAL AND HISTOPATHOLOGICAL PATTERN, SEVERITY, CAUSALITY AND COST ANALYSIS IN HOSPITALISED PATIENTS WITH CUTANEOUS ADVERSE DRUG REACTIONS IN A TERTIARY CARE HOSPITAL
Objectives: To assess clinical and histopathological patterns, causative drugs, causality, severity and cost of treating cutaneous adverse drug reactions (CADRs) among patients admitted in tertiary care teaching hospital. Methods: In a prospective hospital-based study over a period of one year (June 2015- June 2016), CADRs of patients admitted to the dermatology department were recorded. The data ...
In this paper, we investigate several topological indices in honeycomb graphs: Randić connectivity index, sum-connectivity index, atom-bond connectivity index, geometric-arithmetic index, First and Second Zagreb indices and Zagreb polynomials. Formulas for computing the above topological descriptors in honeycomb graphs are given....
A RAPID AND SENSITIVE LC-MS/MS ASSAY FOR THE DETERMINATION OF CLOBAZAM IN HUMAN PLASMA USING ELECTRO SPRAY IONIZATION TECHNOLOGY
A simple, highly sensitive, precise and accurate liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for the rapid quantification of clobazam in human plasma samples. The chromatographic separation was achieved with a reverse phase column Reprosil Gold XBD C18 (100 × 3mm, 3µm) and the mobile phase consisted of 10 mM ammonium acetate buffer and 0.1% acetic acid in metha...
Helminthiasis is also known as worm infection and a endoparasitic disease of humans and other animals in which a part of a body is infected with parasitic worms. Tinospora cordifolia is a well known medicinal plant and widely used in folk medicine ayurvedic system. The objective of this work is to carry out phytochemical screening and in vitro anthelmintic activity of methanolic, petroleum ether a...
CONVENTIONAL AND MICROWAVE ASSISTED SYNTHESIS OF SOME NEW DERIVATIVES OF COUMARIN CONTAINING PYRAZOLINE AND INVESTIGATION OF THEIR ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES
Pyrazoline derivatives, being used as potential medicinal agents, 3-Acetyl-2H-chromen-2one (I) was prepared by Knoevenagel condensation of salicyladehyde with ethylacetoacetate in presence of piperidine. A series of 3-[(2E)-3-substituted-prop-2-enoyl]-2H-chro men-2-one derivatives (II a-h) were prepared by Claisen-Schmidt condensation of 3-acetyl coumarin with aromatic aldehydes. Treatment of 3-su...
HPTLC FINGERPRINTING FOR SIMULTANEOUS QUANTIFICATION OF HARMINE, KAEMPFEROL, DIOSGENIN AND OLEIC ACID IN THE FRUIT EXTRACT OF TRIBULUS TERRESTRIS L. AND ITS FORMULATION
A simple, accurate and reproducible HPTLC method has been developed for the simultaneous quantification of diosgenin, oleic acid, harmine and kaempferol from the methanolic extract of fruits of plant Tribulus terrestris L. and its marketed formulation. The CAMAG HPTLC systems with winCATS software used for the analysis. Double development with mobile phase Toluene: Ethyl acetate: Formic acid: Glac...
A sensitive, simple, accurate and fast method for vitamin C and E determination in pure and drug formulations using spectrophotometric was developed. The developed method is based on the formation of the charge transfer complex via the reaction between vitamins and Fe+3 [FeNH4(SO4)2.12H2O] in the presence of K3Fe(CN)6 which lead the formation of a blue-greenish colored product that has a maximum a...
A new spectrophotometric method is developed for the determination of artesunate (ARTS) in pharmaceutical preparation and bulk drug. The method involved heat-catalyzed derivatization of the drug with acetic anhydride and concentrated sulphuric acid producing a yellow coloured product peaking at 420.6 nm. The optimum conditions of the reaction and the analytical procedures of the assay were establi...
