Desacetylcephapirin sodium  (Synonyms: 脱乙酰头孢匹林钠盐; Deacetylcephapirin sodium)

Desacetylcephapirin sodium (Deacetylcephapirin sodium) is an active metabolite of Cephapirin (HY-A0153A). Desacetylcephapirin sodium has antimicrobial against S. aureus and coagulase-negative staphylococci mastitis pathogen^[1][2].

Antibacterial^[2]

Desacetylcephapirin sodium exhibits inhibitory activity on Streptococcus dysgalactiae, with MIC₅₀s both of 0.25 µg/mL for clinical and subclinical bacterial strain^[2].
Desacetylcephapirin sodium exhibits inhibitory activity on coagulase-negative staphylococci mastitis pathogen, with MIC₅₀s both of 0.12 µg/mL for clinical and subclinical bacterial strain^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
