Avibactam sodium Chemical Properties,Usage,Production

Description

Avibactam sodium (NXL-104), a diazabicyclooctanone compound, is currently the most favoured novel β-lactamase inhibitor. Compared with the three marketed β-lactamase inhibitors, NXL-104 has a long duration of action and reversible covalent binding to the enzyme, and does not induce β-lactamase production.

Characteristics

Avibactam sodium is a novel beta-lactamase inhibitor. In its structure, Na+ readily forms coordination bonds with water molecules. In addition, there are several O atoms as hydrogen bond acceptors and -NH2 as hydrogen bond donors. As a result, avibactam sodium crystallises easily into its hydrated form^[1]. The structure is shown below:

History

Avibactam sodium and its free acid, avibactam, are diazabicyclooctane (DBO)–based, non-β-lactam β-lactamase inhibitors (BLIs) that are used to treat multi-drug–resistant Gram-negative bacterial pathogens. The compounds were jointly developed by Actavis Generics (now part of Teva Pharmaceutical Industries) and AstraZeneca.
In 2015, avibactam sodium, in combination with ceftazidime, a cephalosporin antibiotic, was approved by the US Food and Drug Administration. The dual-drug’s target was complex urinary tract and intra-abdominal infections caused by Gram-negative, often hospital-acquired, bacteria.
In 2018, in the continuing quest to combat multi-drug–resistant bacteria, Eric M. Gordon, Matthew A. J. Duncton, and Mark A. Gallop at Arixa Pharmaceuticals (Palo Alto, CA) prepared analogues of avibactam that are more orally available than the free acid or its salt.

Uses

Avibactam (NXL104) is a novel β-lactamase inhibitor with a non-lactam structural scaffold. NXL104 irreversibly inhibits lactamase from Mycobacterium tuberculosis.

Definition

ChEBI: Avibactam sodium is an organic sodium salt that is the monosodium salt of avibactam. Used in combination with ceftazidime pentahydrate for the treatment of complicated urinary tract infections including pyelonephritis. It has a role as an EC 3.5.2.6 (beta-lactamase) inhibitor, an antibacterial drug and an antimicrobial agent. It contains an avibactam(1-).

Biological Activity

Avibactam[1192491-61-4] is a β-lactamase inhibitor (IC50s = 8, 80, and 38 nM for TEM-1, P99, and KPC-2 β-lactamases, respectively). It restores the antimicrobial activity of ceftazidime , ceftriaxone , imipenem , and piperacillin against antibiotic-resistant Enterobacteriaceae in vitro (MIC90 reduction 4-1,024-fold across 190 E. coli and K. pneumoniae clinical isolates). Formulations containing avibactam have been used to treat carbapenem-resistant Enterobacteriaceae infections.

Synthesis

A solution of sodium 2-ethyl hexanoate (475.0 g, 2.850 mol) in ethanol (2.00 L) was added to a solution of tetrabutylammonium [(2S,5R)-2-carbamoyl-7-oxo-1,6-diazabicyclo[3.2.1]octan-6-yl] sulfate 13 (723.0 g) in ethanol (2.50 l) and water (50 mL) over approximately 1 h, and the temperature was maintained at rt. The reaction mixture was held for 2 h. The product was filtered, washed with ethanol (2 × 2.0 L), and dried to yield a white crystalline solid 1 (395.0 g, 96.2%), mp 259.1–262.4 °C (decomposition); [α]D20 = ?46.40 (c = 0.79, MeOH/H2O = 1/1); 1H NMR (500 MHz, D2O) δ 4.15 (dd, J = 5.8, 2.8 Hz, 1H), 4.01 (d, J = 7.5 Hz, 1H), 3.28 (d, J = 12.2 Hz, 1H), 3.06 (d, J = 12.2 Hz, 1H), 2.23–2.09 (m, 1H), 2.06–1.96 (m, 1H), 1.94–1.82 (m, 1H), 1.81–1.69 (m, 1H). 13C NMR (126 MHz, D2O) δ 174.72 (s), 169.53 (s), 60.43 (s), 59.93 (s), 47.33 (s), 20.03 (s), 18.31 (s).
