Antimicrobial evaluation and action mechanism of chalcone derivatives containing quinoxaline moiety

Abstract: A series of chalcone derivatives containing quinoxaline moieties were synthesized, and their antibacterial activities were evaluated. Antibacterial bioassays indicated that some of the compounds exhibited significant antibacterial activity against Xanthomonas axonopodis pv. Citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Ralstonia solanacearum (Rs) at the concentrations of 50 or 100?mug/cm3. 50% effective concentration (EC50) values of (E)-3-(pyridin-2-yl)-1-[4-(quinoxalin-2-yloxy)phenyl]prop-2-en-1-one against Xac, Xoo, and Rs were 6.72, 15.17, and 9.29?mug/cm3, respectively, which were better than those of bismerthiazol (44.31, 42.46, and 62.36?mug/cm3, respectively). Scanning electron microscopy (SEM) was employed to analyze the mechanism of antibacterial action of that compound toward Xac. Graphical abstract: [Figure not available: see fulltext.].

A study of the synthesis and nonlinear optical properties of 3-substituted 5H-[1,2,4]triazolo[3?,4?:2,3] [1,3,4]thiadiazino[5,6-b]quinoxaline derivatives

3-Alkyl-5H-[1,2,4]triazolo[3?,4?:2,3][1,3,4]thiadiazino[5,6-b]quinoxaline derivatives have been synthesized by the reaction of 4-amino-5-alkyl-4H-1,2,4-triazole-3-thiol and 2,3-dichloroquinoxaline under solvent-free conditions in moderate yields or refluxing in EtOH in the presence of K2CO3 in excellent yields. Third-order, nonlinear optical properties of the quinoxaline derivatives were measured. The replication of linear optics of the new compounds (16a-d) was investigated by UV-Visible techniques in N,Ndimethylformamide as a solvent. The nonlinear absorption coefficient and refraction index of (16a-d) were also measured in N,Ndimethylformamide via a Z-scan method using a continuous-wave, Nd-YAG laser at 532 nm. The nonlinear refraction index was measured from the order of 10-10 m2/W that is caused the compounds appropriate candidate in optoelectronic and electronic modulators and switches.
