: To improve the solubility and permeability of Sparfloxacin (SPX) and enhance its antimicrobial activity in vitro, two unreported pharmaceutical crystalline salts were synthesized and characterized in this paper. One is a hydrated crystal of Sparfloxacin with Pimelic acid (PIA), another is a hydrated crystal of Sparfloxacin with Azelaic acid (AZA), namely, SPX-PIA-HO (2CHFNO·CHO·2HO) and SPX-AZA-HO (4CHFNO·2CHO·5HO). : The structure and purity of two crystalline salts were analyzed using solid-state characterization methods such as single-crystal X-ray diffraction, powder X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, and infrared spectroscopy.

Article Synopsis
  • Norfloxacin (NORF) is a widely used fluoroquinolone antibiotic that has limitations due to its poor water solubility and low oral bioavailability.
  • This study focuses on improving NORF’s biopharmaceutical properties by creating two new hydrate salts using phenolic acid, namely NORF-3,5-DBA hydrate and NORF-VA hydrate.
  • The research shows that these salts significantly enhance NORF's solubility and antibacterial effectiveness, demonstrated by better inhibition of bacteria and reduced minimum inhibitory concentration values.
