生物活性

Cephradine (Cefradine) is a broad-spectrum and orally active cephalosporin. Cephradine is active against both gram-positive and gram-negative pathogens. Cephradine is effective in eradicating most penicillinase-producing organisms. Cephradine has been used in the research of genitourinary, gastrointestinal and respiratory tract infections, and in infections of the skin and soft tissues. Cephradine blocks solar-ultraviolet induced skin inflammation through direct inhibition of TOPK.

体外研究

Cephradine (0~8 μg/mL; 12 hours) makes bacterial viability rapidly increased at antibiotic concentrations below the MIC (minimum inhibitory concentration) of 0.70 µg/mL at both pH 7.4 and pH 5.5.

体内研究

Cephradine (25 mg/kg; s.c.; 11 days) reduces the bacterial density and counts in the abscesses.

Animal Model: Nondiabetic mice
Dosage: 25 mg/kg
Administration: S.c.; 11 days
Result: Reduced the bacterial density and counts in the abscesses.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
