Clerocidin interacts with the cleavage complex of Streptococcus pneumoniae topoisomerase IV to induce selective irreversible DNA damage [PDF]

open access: yes, 2006
Clerocidin (CL), a diterpenoid natural product, alkylates DNA through its epoxide moiety and exhibits both anticancer and antibacterial activities. We have examined CLaction in the presence of topoisomerase IV from Streptococcus pneumoniae.

Development of the quinolones [PDF]

open access: yesJournal of Antimicrobial Chemotherapy, 2003
Since their discovery in the early 1960s, the quinolone group of antibacterials has generated considerable clinical and scientific interest. Nalidixic acid, the first quinolone to be developed, was obtained as an impurity during the manufacture of quinine.

Inhibiting quinolone biosynthesis of Burkholderia

open access: yes, 2021
2-Alkylquinolones are important signalling molecules of Burkholderia species. We developed a substrate-based chemical probe against the central quinolone biosynthesis enzyme HmqD and applied it in competitive profiling experiments to discover the first ...

Crystal structure of 2-chloro-3-(dimethoxymethyl)-6-methoxyquinoline

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C13H14ClNO3, crystallizes with Z′ = 2 in the space group Pca21, but a search for possible additional crystallographic symmetry found none.

Antibacterial Residue Excretion via Urine as an Indicator for Therapeutical Treatment Choice and Farm Waste Treatment

open access: yesAntibiotics, 2021
Many of the infectious diseases that affect livestock have bacteria as etiological agents. Thus, therapy is based on antimicrobials that leave the animal’s tissues mainly via urine, reaching the environment through slurry and waste water.

Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

open access: yesAdvanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

Imidoylketene−Oxoketenimine Interconversion. Rearrangement of a Carbomethoxyketenimine to a Methoxyimidoylketene and 2-Methoxy-4-quinolone

open access: yes, 2016
FVP of triazole 13 produces the isolable ketenimine 11 together with indole 15. 11 undergoes reversible interconversion with imidoylketene 10 above 380 °C. The latter cyclizes to quinolone 12.

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
