ABSTRACT
Treatment of chronic lung infection becomes a great challenge due to the drug resistant bacteria. In this scenario, evolving a new drug based on lipid metal conjugation loaded with potential antibiotic provides better drug delivery. In this study, ciprofloxacin loaded selenium-lipid nanoparticle (CxLSENPs) is produced in a novel route and its antimicrobial properties were tested against clinically important Gram-negative P. aeruginosa. The synthesized CxLSENPs was characterized by biophysical techniques (UV, Fluorescence spectroscopy, Raman spectroscopy, FTIR, FESEM, HRTEM and Zeta potential). Raman spectra coupled with FTIR spectra confirmed the possible interaction of lipid components in the NPs. HRTEM analysis confirmed the spherical shape of NPs. CxLSENPs recorded greater antibacterial effects on P. aeruginosa. A drastic reduction in the count of P. aeruginosa was observed after treatment with CxLSENPs. In order to further confirm the antibacterial efficiency, the live/dead cell assay was carried out. Live/dead analysis helps us to investigate the viability of bacterial cells. The number of dead bacterial cells was significantly higher in CxLSENPs treated groups when compare to the control. Furthermore, CxLSENPs increased the antioxidant enzyme activities (SOD, GPx, CAT and LPO) in mouse and protected the liver damage from bacterial infection. This study concludes that the developed CxLSENPs might be employed as strong antimicrobial and antioxidant agents for treating lung infection or interstitial lung diseases.
