生物活性

Cloxacillin sodium is an orally active antibacterial agent and β-lactamase inhibitor with an IC50 of 0.04 μM. Cloxacillin sodium can suppress the S. aureus-induced inflammatory response by inhibiting the activation of MAPKs, NF-кB and NLRP3-related proteins[1][2][3].

IC50 & Target

Tetracycline

 

體外研究
(In Vitro)

Cloxacillin sodium (0-2048 μg/mL; 20-24 h) shows good antibacterial activity for S. aureus 8325-4 and DU1090 with MIC values both of 0.125 μg/mL[1].
Cloxacillin sodium (0.015625 μg/mL; 6 h) inhibits the hemolytic activity of Hlα in vitro, and this inhibition is not only more pronounced when combined with TZ and TZ, but also suppresses the inflammatory response by inhibiting the activation of MAPKs, NF-кB and NLRP3-related proteins[1].

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

Cell Viability Assay[1]

Cell Line: S. aureus 8325-4, S. aureus DU1090 (an Hlα-deleted strain)
Concentration: 0-2048 μg/mL
Incubation Time: 20-24 h
Result: Inhibited S. aureus 8325-4 and DU1090 with MIC values both of 0.125 μg/mL.

Western Blot Analysis[1]

Cell Line: S. aureus 8325-4
Concentration: 0.015625 μg/mL (combines with Thioridazine (TZ, 0.25 μg/mL) and Tetracycline (TC, 0.03125 μg/mL)).
Incubation Time: 6 h
Result: Inhibited the expression of Hlα and the inhibition was more pronounced when combined with TZ and TC.

Western Blot Analysis[1]

Cell Line: RAW264.7 cells (exposes to S. aureus 8325-4/DU1090 or pure Hlα)
Concentration: 0.015625 μg/mL (combines with TZ (0.25 μg/mL) and TC (0.03125 μg/mL)).
Incubation Time: 6 h
Result: Inhibited the activation of MAPKs, NF-кB and NLRP3-related proteins thereby inhibiting the inflammatory response when combined with TC and TZ.
體內(nèi)研究
(In Vivo)

Cloxacillin sodium (1.6125 mg/kg; s.c.; 12-h intervals for 72 h) protects mice from S. aureus peritonitis in vivo when combines with Thioridazine and Tetracycline[1].
Cloxacillin sodium (7.5 mg/per; i.p.; twice daily from day 3 for 3 days) develops less severe synovitis and reduces bone erosions when combines with anti-IL-15 antibodies[3].

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

Animal Model: Female BALB/c mice (6-week-old; peritonitis model)[1].
Dosage: 1.6125 mg/kg (combines with TC (3.125 mg/kg) and TZ (25 mg/kg))
Administration: Subcutaneous injection; 12-h intervals for 72 h.
Result: Reduced the degree of inflammatory cell infiltration in the mouse lung tissue and alveolar structures tended to be normal.
Significantly reduced the pathological changes in spleen and liver tissue, as well as decreased the CFU counts of S. aureus in the peritoneal cavity.
Animal Model: Female wildtype C57BL/6 mice (8-week-old; systemic S. aureus-induced arthritis model)
Dosage: 7.5 mg/per (combines with 25 μg/per anti-IL-15 antibodies)
Administration: Intraperitoneal injection; twice daily from day 3 (after bacterial inoculation) and stopped at day 6.
Result: Showed activities of reducing severe synovitis and bone erosions when combined with anti-IL-15 antibodies.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
