Aztreonam Usage And Synthesis
OutlineAztreonam is a novel kind ofβ-lactam antibiotics belonging to monobactams. In 1978 it was first discovered from the culture brot of New Jersey soil purple bacterium Chromobacterium violaceum, it has been obtained with synthesis method.
Mechanism
Aztreonam belongs to bacteria fungicides. It can quickly go through the outer membrane of Gram-negative aerobic bacteria wall, while it has a high affinity with the penicillin-binding protein 3 (PBP-3) . By acting on the PBP-3 and inhibiting synthesis of bacterial cell wall , it leads to cell lysis and death.
Aztreonam has a narrow antimicrobial spectrum, it only has antibacterial effect on aerobic gram-negative bacilli , such as E. coli, Klebsiella, Serratia spp, Proteus mirabilis, indole-positive Proteus, Citrobacter, influenza addicted blood coli, Pseudomonas aeruginosa and other Pseudomonas, some Enterobacter, Neisseria gonorrhoeae. The product is highly stable to β-lactamase produced by many bacteria .it is inactive in Gram-positive bacteria and anaerobic bacteria . Aztreonam compared with ceftazidime, gentamicin, it effect on aerogenes, and Enterobacter cloacae is higher than ceftazidime, but lower than gentamicin; the effect on Pseudomonas aeruginosa is lower than ceftazidime , and similar to gentamicin .
indicationsIt is mainly used for the treatment of infections caused by susceptible strains which include the respiratory system, urinary, reproductive system infections (including acute gonorrhea), intra-abdominal infections, skin and soft tissue infections, before surgery preventing infections, other serious infections, such as sepsis.
Precautions 1.contraindication: patients allergic to the products or having a history of allergy on lidocaine and other local anesthetics or having anaphylactic shock on other β-lactam drugs are banned.
2. caution following:
It does not exist cross-allergic reactions between aztreonam and penicillins, but people having allergy body and allergic to penicillins, cephalosporins should take caution.
renal dysfunction patients should take caution.
aztreonam does not have toxicity for liver , but the patients having impaired liver function should observe the dynamic changes. It has been reported that in patients with alcoholic cirrhosis , the total clearance of the products can be reduced by 20-25%.
pregnant and lactating women, infants and young children should use with caution.
3. The impact of drugs on clinical outcomes:
direct anti-human globulin test (Coombs test) can be positive.
there may be a temporary increase of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and serum creatinine values after medication among a few patients, part thromboplastin time (PTT) and prothrombin time (PT) may be extended.
adverse reactions are skin symptoms such as skin rashes, purpura, pruritus (approximately 2%); gastrointestinal symptoms such as diarrhea, nausea, vomiting, taste changes, jaundice, and drug-induced hepatitis (approximately 2%); local irritation such as thrombophlebitis. Injection site swelling (approximately 2.4%); there are other neurological symptoms, vaginitis, oral lesions, fatigue, dizziness, and bleeding.
4. Long-term medication should pay attention to monitoring of liver, kidney and hematopoietic system.
The above information is edited by the chemicalbook of Tian Ye.
Chemical propertieswhite or colorless powder crystals, melting at 227 ℃ (decomposition). It is dissolved in dimethyl formamide, slightly soluble in methanol, very slightly soluble in ethanol, insoluble in toluene, chloroform or ethyl acetate.
Aztreonam disodium: C13 H15N5Na2O8 . Acute toxicity LD50 (mg/kg): 3300 intravenous injection in mice, 6600 in rats intraperitoneally.
UsesIt is Mainly used for the infections caused by sensitive gram-negative bacteria , including pneumonia, pleurisy, abdominal infections, biliary tract infections, bone and joint infections, skin and soft tissue inflammation, especially for urinary tract infections, but also for sepsis. Because this product has good resistance to enzyme performance, therefore, when a microorganism is not sensitive to penicillins, cephalosporins, aminoglycosides and other drugs ,the product should often be effective.
production methodThreonine for raw materials,chloride resulting from the chlorination forms an amide through ammonolysis, protect α-amino with benzyl chloroformate,esterifyβ-hydroxy with methanesulfonyl chloride , the amide group is sulfonated with sulfuric acid tetrabutylammonium , then it is cyclized to generate azetidine derivative in the potassium bicarbonate, then after hydrogen and Deprotection, produce 3-amino-2-methyl-4-oxo-1-sulfo-N oxetane.
Afetr dehydration amidation of side chains Azetidine derivative and thiazole derivatives obtained in the above, hydrolyse to deprotect and to obtain aztreonam.

DescriptionAztreonam is the first member of the monobactam class of antibiotics to be introduced into the world market. It possesses high β-lactamase stability and moderately good activity against gram negative aerobes such as E. coli, S. marcescens, -9 Proteus Providencia, Salmonella, g. influenzae, E. gonorrhea, and &. pneumonia. While somewhat less potent against Pseudomonas aeruginosa, it is nonetheless one of the better β-lactams against this species. It has poor activity against gram positive organisms.

Usesantiserotonin
UsesAztreonam is a synthetic β-lactam antibiotic of the monobactam class. It is effective against Gram-negative bacteria but inactive against Gram-positive bacteria. Its mechanism of action involves the inhibition of mucopeptide synthesis in the bacterial cell wall, thereby blocking peptidoglycan crosslinking. Aztreonam is resistant to hydrolysis by some β-lactamases, but is inactivated by extended-spectrum β-lactamases.
UsesThe first totally synthetic monocyclic ?lactam antibiotic
Brand nameAzactam (Bristol-Myers Squibb);PRIMBACTAM.
Antimicrobial activityConcentrations (mg/L) inhibiting 50% of other organisms are: Aeromonas spp., 0.1;Acinetobacter spp., 16; Mor. catarrhalis, 0.1; Burkholderia cepacia, 2; and Yersinia spp., 0.1. Synergy has been shown with gentamicin, tobramycin and amikacin against 52–89% of strains of Ps. aeruginosa and gentamicin-resistant Gram-negative bacteria.
General DescriptionAzactam (aztreonam for injection, intravenous or intramascular)contains the active ingredient aztreonam, which is amember of the monobactam class of antibiotics. A true antibiotic,aztreonam was originally isolated from cultures ofthe bacterium Chromobacterium violaceum. Now, the antibioticis prepared by total synthesis. Monobactams possessa unique monocyclic β-lactam nucleus, and are structurallyunlike other β-lactams like the penicillins, cephalosporins,carbapenems, and cephamycins. The β-lactam arrangementof aztreonam is unique, possessing an N-sulfonic acid functionality.This group activates the β-lactam ring towardattack. The side chain (3-position) aminothiazolyl oximemoiety and the 4-methyl group specify the antibacterialspectrum and β-lactamase resistance.
The mechanism of action of aztreonam is essentially identicalto that of other β-lactam antibiotics. The action of aztreonamis inhibition of cell wall biosynthesis resulting from ahigh affinity of the antibiotic for penicillin binding protein 3(PBP-3). Unlike other β-lactam antibiotics, aztreonam doesnot induce bacterial synthesis of β-lactamases. The structureof aztreonam confers resistance to hydrolysis by penicillinasesand cephalosporinases synthesized by most Gramnegativeand Gram-positive pathogens. Because of theseproperties, aztreonam is typically active against Gram-negativeaerobic microorganisms that resist antibiotics hydrolyzedby -lactamases. Aztreonam is active against strains that aremultiply-resistant to antibiotics such as cephalosporins, penicillins,and aminoglycosides. The antibacterial activity ismaintained over a broad pH range (6–8) in vitro, as well as inthe presence of human serum and under anaerobic conditions.
Aztreonam for injection is indicated for the treatment ofinfections caused by susceptible Gram-negative microorganism,such as urinary tract infections (complicated and uncomplicated),including pyelonephritis and cystitis(initial and recurrent) caused by E. coli, K. pneumoniae, P.mirabilis, P. aeruginosa, E. cloacae, K. oxytoca, Citrobactersp., and S. marcescens. Aztreonam is also indicated for lowerrespiratory tract infections, including pneumonia and bronchitiscaused by E. coli, K. pneumoniae, P. aeruginosa, H.influenzae, P. mirabilis, S. marcescens, and Enterobacterspecies. Aztreonam is also indicated for septicemia causedby E. coli, K. pneumoniae, P. aeruginosa, P. mirabilis, S.marcescens, and Enterobacter spp. Other infections respondingto aztreonam include skin and skin structure infections,including those associated with postoperative wounds andulcers and burns. These may be caused by E. coli, P.mirabilis, S. marcescens, Enterobacter species, P. aeruginosa,K. pneumoniae, and Citrobacter species. Intra-abdominalinfections, including peritonitis caused by E. coli,Klebsiella species including K. pneumoniae, Enterobacterspecies including E. cloacae, P. aeruginosa, Citrobacterspecies including C. freundii, and Serratia species includingS. marcescens. Some gynecologic infections, including endometritisand pelvic cellulitis caused by E. coli, K. pneumoniae,Enterobacter species including E. cloacae, and P.mirabilis also respond to aztreonam.
PharmacokineticsCmax 1 g intravenous: 90 mg/L end infusion
1 g intramuscular: 46 mg/L after 1 h
Plasma half-life: 1.7 h
Volume of distribution: 0.18 L/kg
Plasma protein binding: 56%
Absorption and distribution
Oral bioavailability is less than 1%. Peak concentrations above the median MIC for most Gram-negative pathogens are achieved in most tissues and body fluids after 1 g intramuscular or intravenous doses.
Metabolism and excretion
It is not extensively metabolized, the most prominent product, resulting from opening the β-lactam ring, being scarcely detectable in the serum and accounting for about 6% of the dose in the urine and 3% in the feces.
It is predominantly eliminated in the urine, where 58–72% appears within 8 h. Less than 12% is eliminated unchanged in the feces, suggesting low biliary excretion.
Clinical UseUrinary tract infections, including pyelonephritis and cystitis
Lower respiratory tract infections, including pneumonia and bronchitis
caused by Gram-negative bacilli
Septicemia
Skin and skin structure infections, including postoperative wounds, ulcers
and burns
Intra-abdominal infections, including peritonitis
Gynecological infections, including endometritis and pelvic cellulitis
Side effectsLocal reactions occasionally occur at the injection site. Systemic reactions include diarrhea, nausea and/or vomiting and rash (1–1.3%). Neutropenia was seen in 11.3% of the pediatric patients younger than 2 years. Pseudomembranous colitis has been reported.
There are no reactions in patients with immunoglobulin E (IgE) antibodies to benzylpenicillin or penicillin moieties. It is rarely cross-reactive with other β-lactam antibiotics and is weakly immunogenic.
Safety ProfileModerately toxic by severalroutes. An experimental teratogen. Other experimentalreproductive effects. When heated to decomposition itemits toxic fumes of NOx and SOx.
Veterinary Drugs and TreatmentsAztreonam is a monobactam antibiotic that may be considered for use in small animals for treating serious infections caused by a wide variety of aerobic and facultative gram-negative bacteria, including strains of Citrobacter, Enterobacter, E. coli, Klebsiella, Proteus, Pseudomonas and Serratia. The drug exhibits good penetration into most tissues and low toxic potential and may be of benefit in treating infections when an aminoglycoside or a fluoroquinolone are either ineffective or are relatively contraindicated. Any consideration for using aztreonam must be tempered with the knowledge that little clinical experience or research findings have been published with regard to target species.
Aztreonam has also been used to treat pet fish (koi) infected with Aeromonas salmonocida.
