Résumé
A facile and efficient method for the synthesis of novel derivatives of FQ citrate conjugates with 1,2,4-triazoles and 1,3,4-oxadiazole scaffolds 8-11 using conventional, as well as microwave irradiation methods, was reported. Based on these original building blocks, the new derivatives of 3, 7-disubstituted fluoroquinolones bearing the oxadiazolyl-triazole groups were obtained. These invaluable derivatives are of great interest in medicinal and pharmaceutical studies because of their important biological properties. All the reactions were examined under conventional as well as microwave mediated conditions. The structures of obtained compounds were confirmed by A novel approach for the synthesis of benzylthio-1,2,4-triazole and 1,3,4-oxadiazoles core with regioisomeric norfloxacin citrate conjugates was developed. Among the title compounds, 11b, 10a reveal pronounced activity against S. pneumoniae with minimum inhibitory concentrations of 0.89, 0.96 mg/mL and MBCs of 2.95, 2.80 mg/mL, respectively. Minimum Fungicidal Concentration (MFC) has been determined for each compound against two fungal strains. Compound 11b showed maximum anti-cancer activity against HeLa cell line with IC The present work, through simple synthetic approaches, led to the development of novel hybrids of fluoroquinolone containing citrate-triazole-oxadiazole pharmacophores that exhibited remarkable biological activities against different microorganisms and cell lines.

BACKGROUND & OBJECTIVE
A facile and efficient method for the synthesis of novel derivatives of FQ citrate conjugates with 1,2,4-triazoles and 1,3,4-oxadiazole scaffolds 8-11 using conventional, as well as microwave irradiation methods, was reported. Based on these original building blocks, the new derivatives of 3, 7-disubstituted fluoroquinolones bearing the oxadiazolyl-triazole groups were obtained. These invaluable derivatives are of great interest in medicinal and pharmaceutical studies because of their important biological properties.
METHODS
All the reactions were examined under conventional as well as microwave mediated conditions. The structures of obtained compounds were confirmed by
RESULTS
A novel approach for the synthesis of benzylthio-1,2,4-triazole and 1,3,4-oxadiazoles core with regioisomeric norfloxacin citrate conjugates was developed. Among the title compounds, 11b, 10a reveal pronounced activity against S. pneumoniae with minimum inhibitory concentrations of 0.89, 0.96 mg/mL and MBCs of 2.95, 2.80 mg/mL, respectively. Minimum Fungicidal Concentration (MFC) has been determined for each compound against two fungal strains. Compound 11b showed maximum anti-cancer activity against HeLa cell line with IC
CONCLUSION
The present work, through simple synthetic approaches, led to the development of novel hybrids of fluoroquinolone containing citrate-triazole-oxadiazole pharmacophores that exhibited remarkable biological activities against different microorganisms and cell lines. The compounds showed suitable druglike properties and are expected to present good bioavailability profile. An efficient combination of molecular modeling and biological activity provided an insight into QSAR guidelines that could aid in further development and optimization of the norfloxacin derivatives.
