生物活性

Lascufloxacin (KRP-AM1977X) is a potent and orally active fluoroquinolone antibacterial agent. Lascufloxacin potently inhibits infections caused by various pathogens, including quinolone-resistant strains. Lascufloxacin has the potential for various infectious diseases treatment, including lower respiratory tract infections[1][2].

IC50 & Target

Quinolone

 

体外研究
(In Vitro)

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. Lascufloxacin shows potent activity against macrolide-resistant M. pneumoniae isolates with an MIC90 of 0.12 μg/mL[1].
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[1].

体内研究
(In Vivo)

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.]) [2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
