Description

RNAIII-inhibiting peptide(TFA) is a potent inhibitor of Staphylococcus aureus, effective in the diseases such as cellulitis, keratitis, septic arthritis, osteomylitis and mastitis.

IC50 & Target

Staphylococcus aureus[1]

In Vitro

RNAIII-inhibiting peptide(TFA) is a potent inhibitor of Staphylococcus aureus. RNAIII-inhibiting peptide (RIP) inhibits the synthesis of both RNAII and RNAIII, while RAP activates in wild type S. aureus cells. RNAIII-inhibiting peptide (5 μg/106 cells) potently reduces bacterial cell adhesion to HEp2 cells in the absence of serum, but with slight overall reduction the presence of serum. RNAIII-inhibiting peptide inhibits while RAP induces the phosphorylation of TRAP[1].

In Vivo

RNAIII-inhibiting peptide (20 mg/kg, i.v.) decreases lethality in mice challenged with S. aureus ATCC 25923, with the lethality rate of 70%, and when combined with cefazolin, imipenem, vancomycin, the rates are 20%, 15% and 10%. RNAIII-inhibiting peptide (20 mg/kg, i.v.) also causes decreased lethality in mice challenged with S. aureus Smith, with the lethality rate of 75%, and the lethality rate decreases to 30%, 10% and 10% when combined with cefazolin, imipenem, vancomycin[2].

Mice[2]
Mice are randomized to receive intravenously isotonic sodium chloride solution (controls C1 and C2) and 20 mg/kg RNAIII-inhibiting peptide alone or combined with 20 mg/kg cefazolin, 10 mg/kg imipenem, or 10 mg/kg vancomycin. Animals are returned to individual cages and monitored for 7 days. The endpoints of the study are quantitative plasma bacterial evaluation and lethality. For each animal model, toxicity is evaluated on the basis of the presence of any drug-related adverse effects, i.e. local signs of inflammation, anorexia, weight loss, vomiting, diarrhea, fever, and behavioral alterations. In particular, to evaluate the physiological effects of RNAIII-inhibiting peptide, temperature, pulse, blood pressure, respirations and oxygenation are monitored in a supplementary RNAIII-inhibiting peptide-treated group without infection[2].
