Synthesis and biological evaluation of a new series of 4-alkoxy-2-arylquinoline derivatives as potential antituberculosis agents
(2015)
Three new series of 33 quinolone compounds, 2-(2-, 3-, and 4-fluorophenyl)-4-O-alkyl(C5−15) quinolines (7a– k, 8a–k, and 9a–k), were synthesized from 2-(2-, 3-, and 4-fluorophenyl)-2,3-dihydroquinolin-4(1H )-one (4, ...
Antibacterial activity of bryophyte species against Paenibacillus larvae isolates
(2017)
This study was performed to determine the antibacterial activity of methanol extracts of 23 bryophyte species against Paenibacillus larvae isolates that cause American foulbrood diseases in honeybee larvae. The honey and ...
In vitro evaluation of antimicrobial features of vasopressors
(Elsevier Editora Ltda, 2014)
Background: Drugs administered as intravenous infusion may be contaminated during several stages of production or preparation. However studies focusing on antibacterial effects of vasopressor drugs are very rare. This study ...
