Summary
Carumonam (AMA-1080; Ro 17-2301) is a sulfonated monocyclic β-Lactam Antibiotic , targeting to penicillin-binding protein (PBP) . Carumonam exerts highly activity against Enterobacteriaceae , Pseudomonas aeruginosa , and Haemophilus influenzae , while it weakly and even inactively inhibits Streptococcus pneumoniae and Staphylococcus aureus . Carumonam is resistant to beta-lactamase-mediated hydrolysis [1] .
IC50 & Target
Penicillin-binding protein, PBP [1]
In Vitro
Carumonam shows inhibition against
Enterobacteriaceae
isolates with MIC
90
values of 0.013-25 μg/mL, while it inhibits
P. aeruginosa
with a MIC
90
value of 12.5 μg/mL
[1]
.
Carumonam (0-400 μg/mL) has high affinity to binding PBP-3 in
Enterobacteriaceae
and
P. aeruginosa
with IC
50
s as same with or smaller than the MICs
[1]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Carumonam (20 mg/kg; s.c. or i.m.; single dose) is easily absorbed and distributes in high concentrations in plasma, kidneys, liver and lungs in pharmacokinetic analysis in mice, rats, rabbits, dogs and cynomolgus monkeys
[2]
.
Animal: Five-week-old male Slc:ICR mice (20-25 g), 7-week-old male Jcl:SD rats (210-250 g), male New Zealand White rabbits (2.5-3.5 kg), male and female beagle dogs (10-15 kg), and female cynomolgus monkeys (2.8-3.7 kg). They are deprived of feed for 16 to 18 h before the antibiotic was administered; water was given ad libitum
[2]
.
