The chemicals used were of analytic grades, purchased from Sigma Aldrich, Pakistan, and used without purification except where mentioned. Sodium salt of naproxen was received from Moringa Pharma, Pakistan, as a gift. FTIR Prestige−21 (Shimadzu, Kyoto, Japan) was used for FTIR spectra of the synthesized products. Elemental analyses were carried out with an Exeter Analytical Inc-CE-440 Elemental Analyzer. Melting points were determined by a Gallenkamp digital melting point apparatus (MFB−595−010M). Bruker (KAPPA Apex II) XRD was used for determination of crystalline structure. 1H-NMR and 13C-NMR spectra were recorded on a Varian Unity INOVA (300 MHz) spectrometer. 1H-NMR (300 MHz) and 13C-NMR (75 MHz) chemical shift values are reported as δ using the residual solvent signal as an internal standard. All NMR measurements were recorded in CDCl3 as a solvent unless mentioned otherwise. Antibacterial activity was screened by using fresh cultures of different species of bacteria by following the disc diffusion method [42 (link)].

All melting points reported for the monomers, pre-monomers and model compound are uncorrected and determined on a Gallen-kamp Melting Point apparatus with a digital thermometer type MFB-595-010M. Elemental analyses were estimated by an Elemental Analyses system GmbH, VARIOEL, V2.3 July 1998 CHNS Mode. IR spectra were determined on IR-470, Infrared spectrophotometer, Shimadzu using the KBr pellet technique. Room temperature 1H-NMR spectra were carried out on a varian EM-390-NMR (90 MHz) spectrometer and a GNM-LA 400-MHz NMR spectrophotometer using DMSO or CDCl3 as deuterated solvents and in the presence of TMS as an internal reference. Mass spectra were investigated on a Jeol JMS600 mass spectrometer. I-V method (two electrodes composed onto fabricated GCE) was measured for toxic arsenic ions for PAAP/GCE by using Keithley-Electrometer from USA.

All the used organic solvents and metal salts were of analytical grade, purchased from Sigma Aldrich, and used without purification except where mentioned. IR Prestige-21 (Shimadzu) was used to record FT-IR spectra. UV-Vis spectra were recorded on a Shimadzu UV 240 spectrophotometer. The Elico-CM82 Conductivity Bridge was used to measure molar conductance at room temperature. Silica gel (60 F254Merk) coated Al sheets were used for thin-layer chromatography. In both positive and negative ion ESI modes, a mass spectrum was recorded on an Agilent 6224 Time of Flight (TOF) LC-MS mass spectrometer. NMR (1H and 13C) spectra were recorded on a Bruker US400 spectrometer at 400 and 100 MHz in DMSO-d6. An Exeter Analytical Inc-CE-440 Elemental Analyzer was used to carry out elemental analysis of the prepared compounds. The melting points of the products were determined by using the Gallenkamp digital melting point apparatus (MFB-595-010M). APEX3 (Bruker, 2016), SAINT (Bruker, 2016) and Mercury 4.0 were used from visualization to analysis, design and prediction. A thermogravimetric analyzer (TGA Q500) was used to study the thermal degradation trend of compounds at a heating rate of 10 °C min−1 under a nitrogen atmosphere with a flow rate of 5 mL min−1. Alkaline phosphatase inhibitory activity was screened by following the reported method.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
