Imipenem (Primaxin among others) is an intravenous β-lactam antibiotic discovered by Merck scientists Burton Christensen, William Leanza, and Kenneth Wildonger in the mid-1970s.[1] Carbapenems are highly resistant to the β-lactamase enzymes produced by many multiple drug-resistant Gram-negative bacteria,[2] thus play a key role in the treatment of infections not readily treated with other antibiotics.[3]

Imipenem was patented in 1975 and approved for medical use in 1985.[4] It was discovered via a lengthy trial-and-error search for a more stable version of the natural product thienamycin, which is produced by the bacterium Streptomyces cattleya. Thienamycin has antibacterial activity, but is unstable in aqueous solution, so impractical to administer to patients.[5] Imipenem has a broad spectrum of activity against aerobic and anaerobicGram-positive and Gram-negative bacteria.[6] It is particularly important for its activity against Pseudomonas aeruginosa and the Enterococcus species. It is not active against MRSA, however.

Medical uses

Spectrum of bacterial susceptibility and resistance

Acinetobacter anitratusAcinetobacter calcoaceticusActinomyces odontolyticusAeromonas hydrophilaBacteroides distasonisBacteroides uniformis, and Clostridium perfringens are generally susceptible to imipenem, while Acinetobacter baumannii, some Acinetobacter spp., Bacteroides fragilis, and Enterococcus faecalis have developed resistance to imipenem to varying degrees. Not many species are resistant to imipenem except Pseudomonas aeruginosa (Oman) and Stenotrophomonas maltophilia.[7]

Coadministration with cilastatin

Imipenem is rapidly degraded by the renal enzyme dehydropeptidase 1 when administered alone, and is almost always coadministered with cilastatin to prevent this inactivation[8]

Adverse effects

Common adverse drug reactions are nausea and vomiting. People who are allergic to penicillin and other β-lactam antibiotics should take caution if taking imipenem, as cross-reactivity rates are high. At high doses, imipenem is seizurogenic.[9]

Mechanism of action

Imipenem acts as an antimicrobial through inhibiting cell wall synthesis of various Gram-positive and Gram-negative bacteria. It remains very stable in the presence of β-lactamase (both penicillinase and cephalosporinase) produced by some bacteria, and is a strong inhibitor of β-lactamases from some Gram-negative bacteria that are resistant to most β-lactam antibiotics.

SYM

By reaction of thienamycin (I) with methyl formimidate (II) by means of NaOH in water.

SYN 2

WO 0294828

The reaction of (3R,5R,6S)-6-(1(R)-hydroxyethyl)-2-oxo-1-carbapenem-3-carboxylic acid p-nitrobenzyl ester (I) with diphenyl chlorophosphate by (II) means of DMAP and DIEA in DMA/dichloromethane gives the enol phosphate (III), which is condensed with 2-aminoethanethiol (IV) in DMA to yield the 2-aminoethylsulfanyl derivative (V). The reaction of (V) with benzyl formimidate (VI) by means of DIEA in DMA affords the intermediate p-nitrobenzyl ester (VII), which is finally hydrogenated with H2 over Pd/C in water/isopropanol/N-methylmorpholine to provide the target Imipemide.

SYN 3

Tetrahedron Lett 1982,23(47),4903

The condensation of 7-oxo-6-(1-hydroxyethyl)-3-(diphenoxyphosphate)-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylic acid p-nitrophenyl ester (I) with the bis(trimethylsilyl) derivative of 2-(iminomethylamino)ethanethiol (II) in the presence of base gives p-nitrophenyl ester of MK-0787, protected with a trimethylsilyl group (III), which is finally deprotected by hydrogenolysis.
