Occupancies: a0.684 (7); b0.316 (7).
1 Source of materials
Gatifloxacin (GAT) (15.0 mg, 0.04 mmol) and 2,5-dihydroxybenzoic acid (15.0 mg, 0.07 mmol) were dissolved in methanol (5 mL) and water (1.5 mL) at 50 °C. Then, the solution was filtered and the filtrate placed in a 10 mL glass bottle. The glass bottle was covered with a porous film. Single crystal of the title compound were obtained after 7 days.
2 Experimental details
Absorption corrections were applied by using multi-scan program [1]. Using Olex2 [2], the structure was solved with the Shelxt [3] structure solution program and refined with the SHELXL [4] refinement package.
3 Comment
Gatifloxacin is a novel extended-spectrum fluoroquinolone with improved Gram-positive and anaerobe coverage compared with older agents such as ciprofloxacin [5]. The drug is available as tablets and aqueous solutions for intravenous therapy as well as eye drop formulation (Zymar). The crystal structure of 1-cyclopropyl-6-fluoro-8-methoxy-7-(3-methyl-1-piperazinyl)-1,4-dihydro -4-oxo-3-quinolinecarboxylic acid hydrochloride, [C19H23FN3O4]Cl (CCDC:692347) was reported [6]. As one of the fourth-generation quinolones, due to its poor solubility and easy to develop drug resistance, it is difficult to give full play to its clinical effects. In order to improve the physiochemical properties of gatifloxacin, salts were designed and synthesized by pharmaceutical salt forming technology. For example, the solubility of GAT with the pharmaceutical salts of 2,3-dihydroxybenzoic acid increased its solubility, the hygroscopic stability and the antibacterial activities in vitro of GAT-dihydroxybenzoic is also superior to GAT [7]. To improve the solubility of the fluoroquinolone drug gatifloxacin, a pharmaceutical salt of GAT with 2,5-dihydroxybenzoic acid is designed, synthesized, and characterized.
