Ampicillin Trihydrate (NCI-C56086,D-(-)-α-Aminobenzylpenicillin trihydrate) is a β-lactam antibiotic, which inhibits bacterial cell-wall synthesis (peptidoglycan cross-linking) by inactivating transpeptidases on the inner surface of the bacterial cell membrane.

Biological Activity

Description

Features

More effective than levofloxacin and ciprofloxacin against Streptococcus pneumoniae.

Targets

beta-lactamase ^[1]

In vitro
In vitro	Ampicillin Trihydrate (500 mg) results in rapid bactericidal effect for SP34, the concentrations declines to the limit of detection (100 CFU/mL) during the initial 6 hours, and regrowth is not observed over the remaining 18 hours. ^[1]

In Vivo
In vivo	Ampicillin Trihydrate (10 mg/kg) results in half life (t _1/2) of 1.2 hours in goats and 2.48 hours in sheep, clearance (Cl) of 2921 mL/h·kg in goats and 262 mL/h·kg in sheep, ampicillin volume of distribution (Vdarea) of 5673 mL/kg in goats and 992 mL/kg in sheep. ^[2] Ampicillin Trihydrate (0.18 kg/kg-3 kg/kg) results in no dose-related mortality, normal body weights, no compound-related gross or histopathologic lesions and diarrhea in mice and rats. ^[3] Ampicillin in combination of norfloxacin, at a dose of 1g/L, maximally suppresses the numbers of cecal aerobic and anaerobic bacteria in ob/ob mice. Ampicillin in combination of norfloxacin results in a significant improvement in fasting glycemia and oral glucose tolerance reduced liver triglycerides and increased liver glycogen and concomitant reduction of plasma lipopolysaccharides in ob/ob mice. ^[4] Ampicillin trihydrate (20 mg/kg) treats five foals, the mean peak serum ampicillin concentration at two to three days old is 5.0 μg/mL at 1 hours after treatment, the mean peak serum concentration at 16 days to 21 days old is 2.7 μg/mL at 2 hours, the concentrations steadily declines and ampicillin is not detected in the serum from any of the foals by 24 hours, and serum clearance averages 17.7 mL/min/kg at two to three days and 35.8 mL/min/kg at 16 days to 21 days. ^[5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
