Mupirocin calcium hydrate (Synonyms: BRL-4910A calcium hydrate; Pseudomonic acid calcium hydrate)

Cat. No.: HY-N7068
Handling Instructions

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.

Description

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].

In Vitro

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.

Cell Viability Assay[1]

Cell Line: Staphylococcus aureus
Concentration: 0-100 μM/mL
Incubation Time: 24, 48 hours
Result: Resulted in a 90 to 99% reduction at 24 h, with MIC values ranged from 0.12-1.0 μM/mL and MBC values ranged from 4.0-32 μM/mL at 48 h.
In Vivo

MRSA: Meticillin-resistant Staphylococcus aureus
Mupirocin (BRL-4910A, Pseudomonic acid) calcium is well absorbed after oral and parenteral administration but serum antibiotic concentrations were short-lived as a result of extensive degradation to the antibacterially inactive metabolite, monic acid A[1].
Mupirocin calcium (2% ointment; external administration; twice daily; 3-6 d) decreases the total bacterial loads in the skin lesions with either topical treatment[3].
Mupirocin calcium (2% ointment; external administration; 4 d) alleviates MRSA-infected pressure ulcers in mice[4].
Mupirocin calcium (100 mg/mL; s.c.; 7 d) exerts prevention efficacy against vascular prosthetic graft infection due to Staphylococcus epidermidis[5].

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

Animal Model: MRSA skin infection model in mice (10-12 weeks old)[3]
Dosage: 2% ointment
Administration: External administration; twice daily; 3-6 days
Result: Reduced the total bacterial loads in the skin lesions, and decreased by 2.0, 5.1 log10 CFU on day 3 and 6, respectively.
Animal Model: Diabetic pressure ulcer mouse model (33.2-39.2 g)[4]
Dosage: 2% ointment
Administration: External administration; 4 days
Result: Resulted less superficial mats of bacterial colonies, and improved histopathology evaluation.
Animal Model: Adult male Wistar rats (weight 275-325 g)[5]
Dosage: Impregnated with 100 μg of mupirocin/mL; segments:1.5 cm *1 cm2
Administration: Subcutaneous implantation; 7 days
Result: Resulted in preventing S. epidermidis infection of the graft in a rat model with spontaneously bound to collagen-sealed Dacron grafts.
