Pipracil Chemical Properties,Uses,Production

Chemical Properties

Crystalline Solid




Broad spectrum semi-synthetic antibiotic related to Penicillin. Antibacterial.


ChEBI: A penicillin in which the substituent at position 6 of the penam ring is a 2-[(4-ethyl-2,3-dioxopiperazin-1-yl)carboxamido]-2-phenylacetamido group.

brand name

Pipracil (Wyeth).

Antimicrobial activity

It displays good activity against non-β-lactamaseproducing strains of N. gonorrhoeae, ampicillin-susceptible H. influenzae and many Enterobacteriaceae. It is the most active of the antipseudomonal penicillins against Ps. aeruginosa and retains its activity in the absence of a β-lactamase inhibitor. Synergy with aminoglycosides has been demonstrated against many strains of Enterobacteriaceae and Ps. aeruginosa.

Acquired resistance

There is complete cross-resistance with other ureidopenicillins, but ticarcillin-resistant strains of Ps. aeruginosa may be susceptible. Piperacillin-resistant strains of B. fragilis and other Bacteroides spp. are common. Because piperacillin is hydrolyzed by most β-lactamases, many β-lactamaseproducing isolates are resistant unless it is protected by β-lactamase inhibitors.


Oral absorption: Negligible
Cmax 2 g (2–3 min intravenous injection): 305 mg/L after 5 min
Plasma half-life: 0.9 h
Volume of distribution: 16–24 L/1.73 m2
Plasma protein binding: 16%
In patients with meningitis, mean CSF penetration of 30% has been found. The urine is the principal route of excretion, 50–70% of the dose appearing over 12 h, most in the first 4 h. Most is excreted via the tubules, 75–90% in active form. The half-life is prolonged in renal failure but much less than is the case with carboxypenicillins. There is substantial biliary excretion, levels in the common duct bile after a 1 g intravenous dose commonly reaching 500 mg/L or more. During hemodialysis the plasma half-life remains elevated and only 10–15% of the dose is removed.

Clinical Use

Piperacillin (Pipracil) is the most generally useful of the extended-spectrum acylureidopenicillins. It is more active thanmezlocillin against susceptible strains of Gram-negativeaerobic bacilli, such as Serratia marcescens, Proteus,Enterobacter, Citrobacter spp., and P. aeruginosa.Mezlocillin, however, appears to be more active againstProvidencia spp. and K. pneumoniae. Piperacillin is alsoactive against anaerobic bacteria, especially B. fragilis andS. faecalis (enterococcus). β-Lactamase–producing strainsof these organisms are, however, resistant to piperacillin,which is hydrolyzed by S. aureus β-lactamase. The β-lactamase susceptibility of piperacillin is not absolute becauseβ-lactamase–producing, ampicillin-resistant strainsof N. gonorrhoeae and H. influenzae are susceptible topiperacillin.
Piperacillin is destroyed rapidly by stomach acid; therefore,it is active only by intramuscular or intravenousadministration. The injectable form is provided as the white,crystalline, water-soluble sodium salt. Its pharmacokineticproperties are very similar to those of the other acylureidopenicillins.

Clinical Use

Intra-abdominal infection
Urinary tract infections
Gynecological and gonococcal infections
Lower respiratory infections
Skin and skin structure infections
Bone and joint infections

Side effects

Piperacillin is generally well tolerated, with mild to moderate pain on injection, thrombophlebitis and diarrhea in some patients. It otherwise exhibits side effects common to the group, including hypersensitivity, leukopenia and abnormalities of platelet aggregation without coagulation defect, except on prolonged treatment.

Enzyme inhibitor

This semisynthetic broad-spectrum antibiotic (FWfree-acid = 517.56 g/mol; CAS 61477-96-1; 59703-84-3 for monosodium salt), known systematically as (2S,5R,6R)-6-{[(2R)-2-[(4-ethyl-2,3-dioxo-piperazine-1-carbonyl)- amino]-2-phenylacetyl]amino}-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2. 0]heptane-2-carboxylic acid, inhibits proteoglycan biosynthesis. Piperacillin is often used in combination with tazobactam and marketed as Tazocin?, Zosyn?, Brodactam? and Trezora?. Target(s): penicillin-binding protein-3; serine-type D-Ala-D-Ala carboxypeptidase, or D-alanine carboxypeptidase.
