Ciprofloxacin hydrochloride

A broad-spectrum antimicrobial carboxyfluoroquinoline. (In Vitro) :Ciprofloxacin (Bay-09867) monohydrochloride (5-50 μg/mL; 0-24 h; tendon cells) inhibits cell proliferation and causes cell cycle arrest at the G2/M phase.Ciprofloxacin (Bay-09867) monohydrochloride shows potent activity against Y. pestis and B. anthracis with MIC90 of 0.03 μg/mL and 0.12 μg/mL, respectively. (In Vivo) :Ciprofloxacin (Bay-09867) monohydrochloride (30 mg/kg; i.p.; for 24 hours; BALB/c mice) has protection against Y. pestis in murine model of pneumonic plague.Ciprofloxacin (Bay-09867) monohydrochloride (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.Ciprofloxacin (Bay-09867) monohydrochloride (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.
