Both complexes were characterized by the elemental combustion analysis, UV-visible and FT–IR spectroscopy, thermal analysis, and single crystal X-ray diffraction. From the crystal structure of complexes, it is evident that each copper (II) ion is six-coordinate and is bonded to chelating tmen. The complexes of copper (II) and TMEDA with Naproxen and Nimesulide were in the ratio 1:2:1. The Complexes were blue in colour and their melting points were recorded as 196 °C and 220 °C respectively. UV- Visible spectra of complexes exhibited three absorptions. The intense absorption band at higher energy was 250 nm and 300nm for both complexes respectively. Both complexes were found to possess antibacterial properties against four strains, including <em>Staphylococcus aureus</em>, <em>Bacillus spizizenii</em>, <em>Escherichia coli</em>, and <em>Klebsiella pneumonia</em>.</p> Muzamal Tehzeeb, Syeda Shahzadi Batool, Muhammad Arfan Hadyait Copyright (c) 2020 PSM https://creativecommons.org/licenses/by-nc/4.0/ https://journals.psmpublishers.org/index.php/ijnas/article/view/387 Wed, 25 Mar 2020 00:00:00 +0000 Copper(II) Complexes as Potential Antibacterial Agents https://journals.psmpublishers.org/index.php/ijnas/article/view/388 <p>There is increasing interest in the use of copper (Cu)-containing complexes to combat bacterial infections. The antibacterial potential of two copper(II) complexes namely, (+) -(S)-2-(6-Methoxynaphthalen-2-yl) propanoic acid (Naproxen) and N-(4-Nitro-2-phenoxyphenyl)methanesulfonamide (nimesulide) was studied against a range of medically significant pathogens, including <em>Staphylococcus aureus</em>, <em>Bacillus spizizenii</em>, <em>Escherichia coli</em>, and <em>Klebsiella pneumonia</em>. The antimicrobial assay showed that the complexes are active against <em>S. aureus</em> and <em>B. spizizenii</em>, <em>E. coli</em> and <em>K. pneumonia</em>. Hence, complexes possess biological activities and can be used to treat medically significant pathogens.</p> Muhammad Naeem Iqbal, Asfa Ashraf Copyright (c) 2020 PSM https://journals.psmpublishers.org/index.php/ijnas/article/view/388 Fri, 31 Jan 2020 00:00:00 +0000 A Spotlight on Physiology Teaching: Crossing the Bridges and Building the Channels in Teacher-Student Communication https://journals.psmpublishers.org/index.php/ijnas/article/view/389 <p>No abstract is available.</p> Shimaa Mohammad Yousof Copyright (c) 2020 PSM https://journals.psmpublishers.org/index.php/ijnas/article/view/389 Fri, 31 Jan 2020 00:00:00 +0000
