Haemophilus Influenza Infection

Nemonoxacin malate solution is mainly composed of Nemonoxacin malate hemihydrate (HY-14956A). Nemonoxacin (TG-873870) malate is a nonfluorinated quinolone antibiotic. Nemonoxacin malate has broad-spectrum activity against Gram-positive, Gram-negative and atypical pathogens. Nemonoxacin malate can inhibit drug-resistant Streptococcus pneumoniae and Methicillin-resistant Staphylococcus aureus. Nemonoxacin malate can be used for the research of community-acquired pneumonia.

Cefcanel is an orally active cephalosporin and antibacterial agent. Cefcanel inhibits growth of methicillin-susceptible Staphylococcus aureus, methicillin-susceptible Staphylococcus epidermidis, Haemophilus influenzae, Moraxella catarrhalis. Cefcanel acts as a substrate hydrolyzed by TEM-1, TEM-3, and Moraxella Bro-1 beta-lactamases.

LY164846 is an orally active cephalosporin. LY164846 is highly sensitive to Haemophilus influenzae (including Ampicillin (HY-B0522)-resistant strains) and Moraxella catarrhalis (with MIC₉₀ ≤ 4 μg/mL). LY164846 is generally sensitive to Methicillin (HY-121544)-resistant Staphylococcus aureus and Streptococcus (except Enterococcus) (with MIC₉₀: 0.25 - 8 μg/mL), and moderately sensitive to anaerobic bacteria. LY164846 has MBC/MIC ratio to Haemophilus influenzae of ≤ 2, showing bactericidal activity. LY164846 can be used for research on respiratory and skin infections.

Desmycosin is a macrolide antibiotic. Desmycosin exhibits biological activity against H. influenzae, S.aureus, S. pneumoniae, and S. pyogenes with MIC values of 4, 1, <0.125, and <0.125 µg/ml, respectively. Desmycosin is an acidic degradation product of tylosin.

Cefdaloxime is an orally active cephalosporin and HR-916 ester metabolite. Cefdaloxime has a broad spectrum of activity against pathogens such as the majority of members of the family Enterobacteriaceae, staphylococci, Streptococcus spp., Neisseria gonorrhoeae, Moraxella catarrhalis, Haemophilus influenzae.

CGP 31523A is a broad-spectrum aminothiazole cephalosporin. CGP 31523A exhibits potent inhibitory effects on Enterobacteriaceae, Neisseria, Haemophilus influenzae, and Streptococcus (except Enterococcus faecalis), among others. CGP 31523A can be hydrolyzed by the common Escherichia coli type Ic β-lactamase, but is stable against the Ia type enzyme. CGP 31523A is neither an effective β-lactamase inhibitor nor does it induce the production of β-lactamase. CGP 31523A can be used for studying infections caused by Gram-negative bacteria (including drug-resistant strains).
