Streamlined turn-off fluorescence sensing of Donepezil: Enhancing evaluation in pharmaceutical formulations, quality control labs, and biological fluids at nano levels.

Donepezil (DPZ) is used to treat Alzheimer's disease by increasing acetylcholine in the brain, necessitating precise analytical methods for its evaluation. This study aims to develop and validate a new turn-off fluorescence sensing method for quantifying DPZ, enhancing its evaluation in pharmaceutical formulations, quality control laboratories, and biological fluids. By leveraging the fluorescence-quenching interplay between DPZ and tetrabromofluorescein, the assay parameters were fine-tuned to enhance the development of an ion-associated complex.

Facile and green chemistry-compatible fluorescence spectroscopic applications of acid red 87 used to evaluate eletriptan, antimigraine, in its pharmaceutical and biological samples.

Eletriptan (ETR), a selective pharmaceutical agent agonist of the 5-hydroxytryptamine1 receptor subtype, are primarily used to treat acute migraine attacks. ETR is a triptan-class medication that works by narrowing cerebral blood vessels and reducing chemicals that produce headache pain, light and sound sensitivity, and nausea. Due to its effectiveness in reducing migraine symptoms, it is a worthwhile choice for those looking for quick and efficient treatment.

Synergistic utility of NBD-Cl fluorogenic loading activity and salting-out assisted liquid-liquid extraction as sample pretreatment in rasagiline tracking in different matrices.

A typical drug used to treat Parkinson's disease is called rasagiline. It belongs to an assortment of drugs known as monoamine oxidase inhibitors, which function by raising dopamine levels in the brain. This work created a unique spectrofluorimetric method for the analytical assay of rasagiline for the first time.

Application of isoindole fluorophore formation for determination of linagliptin in the sole and co-formulated tablets: Application for plasma assay and content uniformity testing.

Linagliptin is a new medicament belonging to dipeptidyl peptidase-4 enzyme inhibitors group. The mentioned medication is used to cure type 2 diabetes and is taken orally as a monotherapy or in a co-formulation with metformin. or empagliflozin.

A specific turn-on fluorescence probe for determination of nitazoxanide based on feasible oxidation reaction with hypochlorite: Applying cobalt ferrite nanoparticles for pre-concentration and extraction of its metabolite from real urine samples.

Nitazoxanide is an antimicrobial compound that was originally developed as an antiprotozoal drug. Recently nitazoxanide has been identified as broad-spectrum antiviral agent and redirected for the remediation of some respiratory tract viral infections. In this study, the spectrofluorimetric technique has been applied to determine Nitazoxanide (NTX) in tablets or its metabolite, tizoxanide (TZD), in human urine samples.

Synthesis, characterization, molecular docking, and antibacterial activities of some new nitrogen-heterocyclic analogues based on a -phenolic unit.

Nitrogen-containing heterocycles have shown pharmacological properties against various diseases. Herein, in our study, flavoHB enzyme is a highly promising well-validated target for identification of antibacterial inhibitors using and techniques. To identify a new class of antimicrobial agents, -(4-hydroxyphenyl)-3-oxobutanamide was utilized as a precursor in the synthesis of several nitrogen-based heterocycles (pyridine, pyrimidine, and pyrazole) attached to -phenolic substrates 2-8.

The control of poultry salmonellosis using organic agents: an updated overview.

Salmonellosis is a severe problem that threatens the poultry sector worldwide right now. Salmonella gallinarium and Salmonella pullorum (Fowl typhoid) are the most pathogenic serovars in avian species leading to systemic infection resulting in severe economic losses in the poultry industry. Nontyphoidal serotypes of Salmonella (Paratyphoid disease) constitute a public health hazard for their involvement in food poisoning problems in addition to their zoonotic importance.

High-temperature liquid chromatography for evaluation of the efficiency of multiwalled carbon nanotubes as nano extraction beds for removal of acidic drugs from wastewater. Greenness profiling and comprehensive kinetics and thermodynamics studies.

The retention behavior of a series of acidic drugs, namely ketoprofen (KET), naproxen (NAP), diclofenac (DIC), and ibuprofen (IBU), on the heat-resisting ZORBAX 300SB-C column, was studied thermodynamically using high-temperature liquid chromatography (HTLC). A perfect correlation of the compounds' lipophilicity and the calculated thermodynamic indicators evidenced its contribution to the retention behavior. Besides, the steric fitting has a subsidiary effect on IBU retention.

Pharmacological and natural products diversity of the brown algae genus .

(F. Sargassaceae) is an important seaweed excessively distributed in tropical and subtropical regions. Different species of have folk applications in human nutrition and are considered a rich source of vitamins, carotenoids, proteins, and minerals.

Detection of genes mediating beta-lactamase production in isolates of enterobacteria recovered from wild pets in Saudi Arabia.

Aim: To determine the genetic basis and types of beta-lactamase encountered among enterobacterial isolates of wild pets from the animal exhibit.

Materials And Methods: A total of 17 beta-lactamase-producing enterobacteria recovered from fecal samples of wild pet animals were analyzed for a selected beta-lactamase gene by polymerase chain reaction.

Results: Molecular analysis identified one or more β-lactamase-encoding genes in 14 enterobacterial isolates as a single or gene combination.
