体外研究
(In Vitro) | Ciprofloxacin (Bay-09867) (5-50 μg/mL; 0-24 h; tendon cells) inhibits cell proliferation and causes cell cycle arrest at the G2/M phase[1].
Ciprofloxacin (Bay-09867) shows potent activity againstY. pestisandB. anthraciswith MIC90of 0.03 μg/mL and 0.12 μg/mL, respectively[2].
Cell Cycle Analysis[1] | Cell Line: | Tendon cells | | Concentration: | 5, 10, 20 and 50 μg/mL | | Incubation Time: | 24 hours | | Result: | Decreased the cellularity of tendon cells. |
Apoptosis Analysis[1] | Cell Line: | Tendon cells | | Concentration: | 50 μg/mL | | Incubation Time: | 24 hours | | Result: | Arrested cell cycle at the G2/M phase and inhibited cell division in tendon cells. |
Western Blot Analysis[1] | Cell Line: | Tendon cells | | Concentration: | 50 μg/mL | | Incubation Time: | 0, 6, 12, 17 and 24 hours | | Result: | Down-regulated the expression of CDK-1 and cyclin B protein and mRNA. Up-regulated the expression of PLK-1 protein. |

体内研究
(In Vivo) | Ciprofloxacin (Bay-09867) (30 mg/kg; i.p.; for 24 hours; BALB/c mice) has protection againstY. pestisin murine model of pneumonic plague[3].
Ciprofloxacin (Bay-09867) (100 mg/kg; i.g.; daily, for 4 weeks; C57BL/6J mice) accelerates aortic root enlargement and increases the incidence of aortic dissection and rupture by decreases LOX level and increases MMP levels and activity in the aortic wall[4].
Ciprofloxacin (Bay-09867) (100 mg/kg; i.g.; daily, for 4 weeks; C57BL/6J mice) induces DNA damage and release of DNA to the cytosol, mitochondrial dysfunction, and activation of cytosolic DNA sensor signaling. Ciprofloxacin lactate increases apoptosis and necroptosis in the aortic wall[4].
| Animal Model: | BALB/c mice[3] | | Dosage: | 30 mg/kg | | Administration: | Intraperitoneal injection; for 24 hours | | Result: | Reduced the lung bacterial load in murine model of pneumonic plague. |
| Animal Model: | C57BL/6J mice[4] | | Dosage: | 100 mg/kg | | Administration: | Oral gavage; daily, for 4 weeks | | Result: | Had aortic destruction that was accompanied by decreased LOX expression and increased MMP expression and activity. |
| Animal Model: | C57BL/6J mice[4] | | Dosage: | 100 mg/kg | | Administration: | Oral gavage; daily, for 4 weeks | | Result: | Caused mitochondrial DNA and nuclear DNA damage, leading to mitochondrial dysfunction and ROS production. Increased apoptosis and necroptosis in the aortic wall. |
