The Cu-doped ZnO photocatalysts were prepared with a green and coprecipitation approach by using water hyacinth (
Synthetic modifications of sulfathiazole derivatives become an interesting approach to enhance their biological properties in line with applications. As a result, good candidate and potential class organic compounds play important role towards medicinal chemistry. In present study, one thiazole derivative two new are synthesized 94% 72–81% yields, respectively. Furthermore, the were evaluated for vitro antibacterial activity against Gram-negative (E. coli P. aeruginosa) Gram-positive...
The incorporation of heterocyclic moieties into azo dye derivatives influences the bioactive properties synthesized derivatives.
Porphyrins and their structural analogs have drawn continuous attention owing to physico-chemical properties associated with biological, medical material chemistry. Consequently, many modifications of the porphyrin skeleton been reported as a fundamental tool for tuning variety new classes porphyrinoids emerged. A vast number applications such photodynamic therapy (PDT), redox catalysis, chemosensors, nonlinear optical (NLO) two photon absorption (TPA) studied utilizing these systems. The...
In present study, two pyrazoline derivatives were synthesized and characterized. The 6 9 screened for their antibacterial activity against Gram-negative bacteria (E. coli P. aeruginosa) Gram-positive (S. aureus S. pyogenes). Both displayed good tested bacterial strains. Pyrazoline derivative showed activities with mean inhibition zones of 17.05 ± 0.03 18.2 0.02 mm at 200 µg/mL respectively. also revealed E. pyogenes 19.5 15.2 0.04 100 µg/mL. promising aeruginosa a 17.7 concentration....
A deep‐cavity calix[4]pyrrole anion receptor bearing 5,6‐dichlorobenzimidazole subunits at diametrically opposed meso positions was synthesized and its anion‐binding properties were investigated. The showed higher affinity for fluoride anions than chloride with a high discrimination factor. Significant differences in the solid‐state geometries between complexes observed.
A series of carbazole–benzimidazole conjugates and corresponding BF 2 ‐complexes ( BODIPYs ) are synthesized characterized. Carbazole–benzimidazole by the condensation 1‐formyl carbazole phenylene diamines in good yields. Various substituents introduced into benzimidazole moiety subsequent reaction with 3 • Et O afforded moderate to yield. The structural photophysical properties fluorophores investigated various spectroscopic techniques such as UV /Vis fluorescence spectroscopy, cyclic...
Introduction: In the present work, two novel compounds were synthesized using zinc oxide nanoparticles through green synthesis protocol. The catalyzed reactions afforded good to excellent yields of target 76.3– 98.6%. Methodology: characterized by UV-Vis, IR and NMR. antibacterial activity was screened against Gram-positive bacteria ( Bacillus cereus Staphylococcus aureus ) Gram-negative Escherichia coli Salmonella typhimurium ). Results Discussion: displayed potent bacterial strains. Among...
Laser-induced fluorescence spectroscopy (LIFS) was tested for detecting changes in fruitquality with respect to fruit pigment contents. The technique non-destructively applied on soundmarket apple fruits (Malus domestica Elstar) studying the influencing factors measurementsaiming development of a measuring routine monitor quality. For samepurpose, additional tests were made homogenized apples and their PE extracts. Such initialtests LIFS application pointed out difficulties method analyzing...
Benziporphyrin systems are widely explored, yet alternative improved synthetic routes towards these needed. Here, a fairly and efficient synthesis of the free base its metal complex is well designed. Dimethoxybenzene dicarbinol intermediate was prepared in excellent yields by reacting 4-methoxyphenylmagnesium bromide with isophthaladehyde diethyl ether. Reaction equivalent pyrrole pentafluorobenzaldehyde presence trifluoroacetic acid (TFA), followed oxidation...
