Bacampicillin (hydrochloride)
Based on 1 Customer Validation
Bacampicillin hydrochloride is an orally active semi-synthetic aminopenicillin derivative, prodrug and bactericide that is readily inactivated by β-lactamases. Bacampicillin hydrochloride is hydrolyzed by carboxylester hydrolases and non-specific esterases in the gastrointestinal wall and plasma to form Ampicillin (HY-B0522), and produces higher levels of Ampicillin in rodents in vivo. Bacampicillin hydrochloride exhibits bactericidal activity against Gram-positive and Gram-negative bacteria. Bacampicillin hydrochloride can be used in studies related to bacterial infections.

Biological Activity
Bacampicillin (10-20 μg/mL; 30 min) hydrochloride is stable in synthetic gastric juice (pH 1.2) and phosphate buffer (pH 7.4), but undergoes extensive hydrolysis to Ampicillin (HY-B0522) in the presence of 10% human or rat serum after 30 min incubation at 37°C, with rat serum driving more complete hydrolysis than human serum[1].
Bacampicillin (100 μg/mL; up to 30 min) hydrochloride undergoes rapid first-order hydrolysis to Ampicillin in heparinized human blood, human plasma, and canine plasma at 37°C, with the fastest hydrolysis observed in human blood[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Bacampicillin (135 mg/kg; p.o.; single dose) hydrochloride produces significantly higher and longer-lasting interstitial fluid Ampicillin levels in female SPF-grade Sprague-Dawley rats with subcutaneous tissue cages compared to equimolar doses of Ampicillin[1].
Bacampicillin (135 mg/kg; p.o.; single dose) hydrochloride produces ampicillin concentrations in the kidney and liver tissues of female SPF-grade Sprague-Dawley rats that are 3 to 4 times those of equimolar ampicillin[1].
Bacampicillin (20 mg/kg; p.o.; single dose) hydrochloride exhibits 3-fold higher bioavailability than equimolar ampicillin in female beagle dogs[1].
Bacampicillin hydrochloride (p.o.; single dose) exhibits potent activity against a variety of bacterial infections in female NMRI mice, with better efficacy than Ampicillin[1].

Animal Model:Sprague-Dawley (female, SPF, ~100 g, subcutaneous coil spring tissue cage implantation)[1]
-
Dosage:135 mg/kg
-
Administration:p.o.; single dose
-
Result:Produced mean blood ampicillin concentrations of 33.83 μg/mL (0.25 h).
Produced mean transudate ampicillin concentrations of 0.14 μg/mL (0.25 h).
Resulted in transudate levels consistently two to three times higher than those from equimolar ampicillin, with a statistically significant difference at 2 h, and transudate levels remained significantly detectable at 4 h.
-
Animal Model:Swiss mice (female, 8-12 weeks old, mean body weight 29 g)[2]
-
Dosage:0.40 mg per mouse daily; 0.80 mg per mouse daily; 1.50 mg per mouse daily; 3.00 mg per mouse daily
-
Administration:p.o.; daily; 4 weeks
-
Result:Caused only an insignificant increase in concentrations of both endogenous Enterobacteriaceae and the inoculated amoxycillin-resistant E.coli strain in faeces, with mean log concentrations of the resistant E.
coli strain measuring 3.8 (0.6) at 0.40 mg/day, 3.3 (0.8) at 0.80 mg/day, 4.0 (1.0) at 1.50 mg/day, and 3.9 (0.8) at 3.00 mg/day.
Induced only slight disturbances to colonization resistance-associated flora at 3.00 mg/day, as indicated by minimal increases in relative cecal weight.
Detected a low concentration of β-aspartylglycine in faeces at doses of 2 mg/day and higher.
