Synthesis and Antibacterial Activities of Citral Derivatives
Citral, a bioactive compound in Palmrose oil, although known to have antibacterial effect, has not been used in current drug research. Optimization of the lead structure could enhance the utility of this compound. Hence citral was modified using natural amino acids to produce the Schiff’s base, a potential pharmacophore and the corresponding amines. In this study, we report the synthesis of 9 S...
متن کاملSynthesis and In-vitro Antibacterial Activities of Acetylanthracene and Acetylphenanthrene Derivatives of Some Fluoroquinolones
Novel analogues of N-piperazinyl fluoroquinolones were prepared and evaluated against a panel of Gram-positive and Gram-negative bacteria, to study the effect of introducing bulky anthracene and phenanthrene moieties on the antibacterial effects of norfloxacin, ciprofloxacin and gatifloxacin. Although most of the novel synthesized compounds had lower antibacterial effects, some derivatives show...

متن کاملSynthesis and antibacterial activities of new metronidazole and imidazole derivatives.
New imidazole ring derivatives comprising 1,3-oxazoline, Schiff's bases, thiadiazole, oxadiazole and 1,2,4-triazole moieties are reported. 3-Aminobiimidazol-4-one compounds 7a-c were synthesized by the reaction of compounds 6a-c with hydrazine hydrate. Biimidazole esters 9a-c were converted into biimidazole hydrazide esters 10a-c. Compounds 7a-c and 10a-c were converted into a variety of deriva...
