Aztreonam Usage And Synthesis
Outline Aztreonam 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 .
indications It 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 properties white 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.
Uses It 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 method Threonine 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.
Category Toxic substances

Flammability and hazard characteristics Combustible; combustion produces toxic fumes of nitrogen oxides and sulfur oxides.
Storage Characteristics Ventilated, low-temperature ,dry storeroom.
Extinguishing agent Dry powder, foam, sand, carbon dioxide, water spray.
Chemical Properties White Crystalline Powder
Uses The first totally synthetic monocyclic β-lactam antibiotic.
Uses antiserotonin
Uses The first totally synthetic monocyclic ?lactam antibiotic
Uses Aztreonam 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.
