产品介绍
Lascufloxacin是一种有效的、具有口服活性的氟喹诺酮类抗菌剂。Lascufloxacin 有效抑制由多种病原体 (包括对喹诺酮类耐药的菌株) 引起的感染。Lascufloxacin 可用于多种传染病的研究,包括下呼吸道感染。

产品描述

Lascufloxacin has the potential for various infectious diseases treatment, including lower respiratory tract infections.Lascufloxacin is a potent and orally active fluoroquinolone antibacterial agent. Lascufloxacin potently inhibits infections caused by various pathogens, including quinolone-resistant strains.

体外活性

Lascufloxacin shows potent activity against macrolide-resistant M. pneumoniae isolates with an MIC90 of 0.12 μg/mL. The MICs of Lascufloxacin against parent S. aureus strains ranged from 0.008 to 0.015 μg/mL, and those against fourth-step parC, gyrA, parC, and gyrA mutant strains are all 2 μg/mL. Lascufloxacin shows incomplete cross-resistance against the mutant strains. The activities of Lascufloxacin against first- and second-step mutant strains of S. pneumoniae are more potent than the activities of other quinolones, and the MICs of Lascufloxacin against gyrA and parC double mutants are 0.25 to 0.5 μg/mL.In the Gram-negative bacteria, Lascufloxacin shows antibacterial activities against Moraxella catarrhalis and β-lactamase-negative ampicillin-susceptible and ampicillin-resistant strains of Haemophilus influenzae, with an MIC90 value of 0.06 μg/mL in all cases. The MIC90 values against Enterobacter spp., Klebsiella pneumoniae, and Acinetobacter spp. are 0.25 μg/mL, 0.25 μg/mL, and 0.5 μg/mL, respectively. Lascufloxacin inhibits E. coli and P. aeruginosa with MIC90s of 0.25 μg/mL and 4 μg/mL, respectively. The MIC50 and MIC90 values of Lascufloxacin against M. pneumoniae are 0.12 μg/mL and 0.25 μg/mL, respectively[1].

体内活性

A pharmacodynamic study using a mouse thigh infection model indicates that the ratios of the free area under the curve (fAUC) to MIC in plasma required for bacteriostasis, or 1-log or 2-log CFU killing against S. pneumoniae isolates, are 10, 16, and 28, respectively. Lascufloxacin shows significant bacterial killing in the mouse model when emulated the area under the concentration-time curve (AUC) in plasma in dose of 75 mg per day [q.d.]) [1].
