New carbapenem antibiotic (carbapenem family members)
Biapenem, together with several drugs developed in different companies in the United State, Japan, and China, all belong to the rapid-developing carbapenem family members. It is white to yellowish white crystalline powder, and is a kind of carbapenem-class antibiotics for injection developed by both the Lederle Company in Japan and the Cyanamid Company in the united state in 1989. It has a broad antibacterial spectrum and has an excellent bactericidal effect on Gram-negative, Gram-positive, aerobic and anaerobic bacteria. The C1 position of its structure contains a 1β-methyl group which can enable drugs to be stable to the effects of the dehydropeptidase I (DHP-I) in the human kidney without the necessity to be combined with DHP-I inhibitor for therapy, and thus reducing its renal toxicity, and is also stable to β-lactamase stability; it also has excellent pharmacokinetic properties and low toxicity; It has excellent therapeutic effect on treating various diseases such as concurrent intra-abdominal infections, plastic surgery infections, gynecological infections, ENT infections, lower respiratory tract infections (including bacterial pneumonia), and also concurrent urinary tract infections with a good tolerance and a lower incidence of adverse reactions.
A notable feature of this product is the existence of the 1β-methyl carbapenem (containing bicyclic triazole) located at the S at 2-position. Structure-function relationship studies have showed that the presence of quaternary ammonium cation located in the side chain is the key that affects the outer membrane permeability, making the inhibitory effect of the product on Pseudomonas aeruginosa and anaerobic bacteria be 2 to 4 times as potent as that of imipenem, and the inhibitory effect on the drug-resistant Pseudomonas aeruginosa be 4 to 8 times as potent as that of meropenem, and moreover, making it more effective in treating Acinetobacter spp, anaerobic bacteria than ceftazidime. Thus, it is promising that it is expected to become a novel first-line drug for treating severe infection. The general dose for intravenously infusion of Biapenem is about 300mg with time being 30~60min at 2 times per day.
Antibacterial activity
Studies have shown that biapenem has broad-spectrum and potent antibacterial activity against G+ bacteria, G-as well as anaerobic bacteria, etc. MIC90 range of this product against 456 clinical isolates of G + bacteria was 0.006~3.13μg/ml; for 1145 G-bacteria, the MIC90 range is 0.1~3.13μg/ml with its antibacterial activity being 2 times as strong as imipenem; for most anaerobes, the MIC90 range is 0.05~1.56μg/ml. Biapenem has broad-spectrum antimicrobial activity. The antimicrobial activity of it is similar as that of imipenem and meropenem, and stronger than that latamoxef and ceftazidime. The MIC value and MBC values are ??similar with each other for this drug. Upon MIC concentration, it can cause morphological changes of Pseudomonas aeruginosa and Escherichia coli; upon a concentration higher than MIC, the bacteria exhibits lytic phenomenon. Staphylococcus aureus, GPB, Streptococcus pyogenes and Streptococcus pneumoniae are highly sensitive to the drug; but methicillin-resistant Staphylococcus aureus and GPB are also resistant to this drug.
In addition, this product also has excellent antibacterial activity against Bacteriodes fragilis also with MIC90 being 1.56μg /ml. The research of Ichiro Murakami has shown that this antibacterial activity against clinical isolates of G + bacteria and Enterobacteriaceae of this drug is similar as or slightly weaker than that of imipenem, but with a stronger anti-bacterial activity against Enterobacteriaceae family than imipenem; for non G-fermentation bacteria, especially Pseudomonas aeruginosa and GM-resistant Pseudomonas aeruginosa, this antibacterial activity of this drug is two times as strong as imipenem.
Biapenem has a high affinity to the protein PBP2 and PBP4 of Pseudomonas aeruginosa, exhibiting its excellent antibacterial activity and low endotoxin release property during the bactericidal process. In 2001, the study of Japanese Scholars (Hiraishi.T) had shown that the transient bactericidal action of biapenem against Pseudomonas aeruginosa PAO1 is superior to that of meropenem. In 2005, during the comparison of transient bactericidal effects against Pseudomonas aeruginosa for biapenem, imipenem, and meropenem, Japanese scholars (Shimauchi.C) found that biapenem has a best bactericidal activity within the same treatment time.

2. Biapenem is a kind of carbapenem synthetic antibiotic. Its salt form is white or off-white powder. It is soluble in water, but insoluble in common organic solvents. It is more stable to the action of renal dehydropeptidase than meropenem and is not necessary to be combined with the enzyme inhibitor. It can fight against gram-negative bacteria, especially with a stronger antibacterial activity against Pseudomonas aeruginosa than imipenem; the antibacterial activity against aerobic Gram-positive bacteria is slightly lower than that of imipenem; its anti-anaerobe activity is the same as imipenem.
2. Biapenem is a carbapenem antibiotic. It has in vitro activity against anaerobes. Biapenem is a new parenteral carbapenem antibacterial agent with a broad spectrum of in vitro antibacterial activity encompassing many Gram-negative and Gram-positive aerobic
3. An carbapenem antibacterial.
4. A carbepenem with antibacterial action
Description
Biapenem was introduced in Japan as a parenteral treatment for bacterial
infections. This new 1-β-methylcarbapenem can be prepared by reaction of commercially
available 4-nitrobenzyl protected β-methylcarbapenem enolphosphate with mercapto
bicyclotriazolium chloride, obtained in 11 steps starting from hydrazine, followed by
deprotection of the carboxylic acid function. Biapenem is a bacterial cell wall synthesis
inhibitor with a broad spectrum in vitro antibacterial activity encompassing many Gramnegative
and Gram-positive aerobic and anaerobic bacteria, including species producing
β-lactamases. Like imipenem, biapenem is moderately active against fnferococcus
faecalis and E. faecuirn and is inactive against methicillin-resistant Staphylococcus aureus.
Biapenem is stable to hydrolysis by human renal dihydropeptidase I (DHP-I) and therefore
does not require the coadministration of a DHP-I inhibitor. In clinical trials, biapenem
showed good clinical and microbiological efficacy in the treatment of patients with intraabdominal,
lower respiratory tract and complicated urinary tract infections. After
intravenous administration, the drug is widely distributed, has linear pharmacokinetics and
is mainly excreted in the urine with an elimination half-life of approximately 1 h. Biapenem
is generally well tolerated, the most common adverse events being skin eruptions/rashes,
nausea and diarrhea.

Biapenem 1, (1R,5S,6S,)-2-[(6,7-dihydro-5H-pyrazolo[1,2- α][1,2,4]triazolium-6-yl)thio]-6-yl)thio]-6-[(R)-1-hydroxyethyl]-1- methylcarbapen-2-em-3-carboxylate, is a new non-natural 1β-methylcarbapenem antibiotic which exhibits a wide range of antibacterial activity, remarkable chemical stability, and extensive stability against human renal dehydropeptidase-I. Mercaptobicyclotriazolium chloride 2 useful for the pendant moiety of 1 was successfully synthesized starting from hydrazine hydrate 3 along an economically available synthetic route. The thiol 2 was efficiently exploited for an expeditious synthesis of biapenem 1. Characterization (crystal structure, nonbonded S- - -O interaction, conformational analysis, and CH- - -O hydrogen bonds) of 1 was investigated by its X-ray crystallographic, 1H NMR, and deuteration experiment analyses.
