In livestock systems, clanobutin sodium (CLB) is a pivotal veterinary medication due to its appetite-stimulant features. This contribution aims to design, for the first time, a straightforward and ecological framework for quantifying CLB in various matrices. Relying on a direct mix-and-read assay, tyrosine (TS) and tryptophan (TP) biosensors were exploited as turn-off fluorescence probes for quantifying CLB using λ 274/302 nm and 272/361 nm, respectively.

Drug-drug interactions may amplify or diminish their intended effects, or even produce entirely new effects. Multicomponent mixture HPLC analysis offers a thorough and effective method for comprehending the makeup and behavior of complicated materials, advancing research and development across a range of scientific and industrial domains. A novel experimental design-assisted HPLC methodology for the concurrent investigation of the drug-drug interaction of pholcodine, ephedrine, and guaifenesin in biological fluids has been established.

Article Synopsis
  • This study investigates the use of curcumin (CUR), a natural compound, alongside doxorubicin (DOX) in cancer treatment, highlighting CUR's ability to enhance anti-cancer effects while reducing side effects and drug resistance associated with DOX.
  • The researchers developed a novel synchronous spectrofluorimetric method to simultaneously measure both CUR and DOX, despite their overlapping emission spectra, by using specific wavelength settings (Δλ = 20 nm) and ethanol as a solvent.
  • The method demonstrated high sensitivity and accuracy with low detection and quantitation limits for both compounds, was validated according to regulatory standards, and showed effective application in testing mixtures and human samples with high

Atorvastatin-an oral lipid regulating drug is a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), which is the rate determining enzyme for cholesterol synthesis. Adenine is a purine nucleobase that is found in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to generate genetic information. The binding mechanism of atorvastatin and adenine was studied for the first time utilizing various techniques, including UV-visible spectrophotometry, spectrofluorimetry, synchronous fluorescence spectroscopy (SF), Fourier transform infrared (FTIR), fluorescence resonance energy transfer (FRET), and metal ion complexation.

Favipiravir (FVP) is an oral antiviral drug approved in 2021 for the treatment of COVID-19. It is a pyrazine derivative that can be integrated into anti-viral RNA products to inhibit viral replication. While, adenine is a purine nucleobase that is found in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to generate genetic information.
