Abstract
The main intentof this work is to create novel 1,4-dihydropyridine, pyrimidoquinoline, triazoloquinazolinone, and imidazoquinazolinone dimers through microwave irradiation. These conformers were then evaluated for their capacity to impede the spread of bacteria in vitro against Salmonella typhi, Listeria monocytogenes, Candida albicans, Escherichia coli, and Staphylococcus aureus. The effective positive control substances involved vancomycin and ampicillin.With a MIC level between 57 to 147 mg/mL, substrates 3, 5, 7a, 7b, 9, and 12 shown the modest effectiveness towards inhibiting the growth both of bacteria and fungi. Compounds 13, 19, 15a, 15b, and 17 demonstrated excellent effectiveness in inhibiting the growth of the candida albicans fungus, with MIC level between 51 to 74 mg/mL, matching the positive control.With MIC level between 62 to 82 mg/mL, analogs 13, 19, 15a, and 15b showed outstanding activity against four different bacterial strains for growth suppression. Their activity was comparable to that of the positive control. Furthermore, compound 17 demonstrates remarkable growth inhibitory activity, outperforming the positive control in the 69–86 mg/mL MIC range. The dimer derivative triazoloquinazolinone 17 showed excellent antibacterial efficacy and showed tremendous promise for development into medicinal drugs in the future.
期刊介绍:
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
