Bioactivity | Mupirocin (BRL-4910A, Pseudomonic acid) calcium hydrate is an orally active antibiotic isolated from Pseudomonas fluorescens. Mupirocin calcium hydrate apparently exerts its antimicrobial activity by reversibly inhibiting isoleucyl-transfer RNA, thereby inhibiting bacterial protein and RNA synthesis[1][2]. |
Invitro | Mupirocin (BRL-4910A, Pseudomonic acid) calcium hydrate (0-100 μM; 48 h) shows antibacterial effect against staphylococci, streptococci and certain gram-negative bacteria, with MIC values range from 0.06-0.25 μg/mL (MIC50 =0.12 μg/mL, MIC90 =0.25 μg/mL)[1].Mupirocin calcium hydrate is highly bound (95% bound) to human serum protein, thus results in activity inhibition in the presence of human serum[1].Mupirocin calcium hydrate apparently exerts its antimicrobial activity by reversibly inhibiting isoleucyl-transfer RNA, thereby inhibiting bacterial protein and RNA synthesis[2].Mupirocin calcium hydrate (2% ointment) reduces pro-inflammatory cytokines IL-1β and IL-17 level, decreases tumor necrosis factor-alpha (TNF-α) expression, and increases the leavel of vascular endothelial growth factor (VEGF)[4].Mupirocin calcium hydrate inhibits MS (S. epidermidis ATCC 12228), MR (S. epidermidis (Se56-99)), and VIR (S. epidermidis (Se43-98)) with MICs of 0.25, 1.26, 1.59 mg/L[5].Note: MIC, the minimum inhibition concentration.
