Piperacillin hydrate
Based on 16 publication(s) in Google Scholar
Piperacillin hydrate is a semisynthetic broad-spectrum β-lactam antibiotic which exhibits potent bactericidal activity against Gram-negative bacteria as well as select Gram-positive strains through penicillin-binding proteins. Piperacillin hydrate is most commonly used in combination with the β-lactamase inhibitor Tazobactam (HY-B1418).

製品説明
体外実験
Piperacillin (12.5 μg/mL, 24h) hydrate inhibits 92% of isolates of Pseudomonas aeruginosa, 82% of Serratia marcescens, 73% of Escherichia coli, 61% of Klebsiella spp, and 42% of Enterobacter spp, most Proteus spp. are extremely susceptible. Piperacillin hydrate fails to inhibit the growth of gram-negative bacilli when large inocula were used (minimum inhibitory concentration >25 μg/mL) [2].

-
Animal Model:BALB/c low inoculum model of K. pneumoniae, KEN-11 strain[3].
-
Dosage:100 mg/kg
-
Administration:Intravenous injection (i.v.), 4 times a day, 5 d, in combination with Tazobactam (12.5 mg/kg, i.v., 4 times a day, 5 d)
-
Result:Enabled all mice survived whereas all control mice died by 5 d, decreased the number of bacteria in lungs compared with control group.
Observed no bacteria in the blood of most mice (except for two mice at the early phase) while bacteria were observed in the blood of control group.
Observed few inflammatory cells in the alveoli whereas an influx of numerous inflammatory cells were observed in the control group.

Piperacillin hydrate purchased from MedChemExpress. Usage Cited in: J Exp Med. 2026 Mar 2;223(3):e20241287. [Abstract]
Piperacillin strongly inhibited microbial growth in riboflavin-synthesizing bacteria. Cecal and colonic microbiota from 2.5–3-week-old WT mice were anaerobically collected and cultured in Chopped Meat Carbohydrate Broth with the indicated antibiotics or no antibiotic (No Abx) for 24 hours at 37°C.
