The final targets are established by different types of functional groups on aryl azides with terminal alkynes of pefloxacin via click chemistry in conventional and microwave irradiation conditions. A series of novel derivatives are characterized by proton, carbon nuclear magnetic resonance technique and mass spectral techniques. From screening antibacterial results the 5c, 5d, 5e, 5f and 5g exhibited outstanding activity against Gram-positive and Gram-negative microorganisms compared to CPF.
