Tigecycline Antineoplastic and Immunosuppressive Antibiotics inhibitor

Cat.nr.: S1403

Tigecycline is bacteriostatic and is a protein synthesis inhibitor by binding to the 30S ribosomal subunit of bacteria and thereby blocking entry of Aminoacyl-tRNA into the A site of the ribosome during prokaryotic translation. This compound induces autophagy by downregulating the PI3K-AKT-mTOR pathway.

Opmerking: 1. Zorg ervoor dat de vloeistof helder is voordat u het volgende oplosmiddel toevoegt.
2. Zorg ervoor dat u het/de oplosmiddel(en) in de juiste volgorde toevoegt. U moet ervoor zorgen dat de verkregen oplossing, bij de vorige toevoeging, een heldere oplossing is voordat u verdergaat met het toevoegen van het volgende oplosmiddel. Fysieke methoden zoals vortexen, ultrasoon of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

Werkingsmechanisme (Mechanism of Action)

In vitro

Tigecycline evades the Tet(A-E) efflux pumps, which account for most acquired resistance to tetracycline and minocycline in Enterobacteriaceae and Acinetobacter spp. This compound binds to bacterial ribosomes that have been modified by the Tet(M) protein, a mechanism that compromises all available tetracyclines, and which is frequent in Gram-positive cocci and Neisseria spp. It remains vulnerable to the chromosomally-encoded multidrug efflux pumps of Proteeae and Pseudomonas aeruginosa, and to Tet(X), a tetracycline-degrading mono-oxygenase found, albeit rarely, in Bacteroides spp. Its MICs for enterococci, staphylococci, and streptococci are mostly 0.06–0.25 mg/L, again with little or no skew to the distribution. This agent is prone to oxidation, and MIC values, particularly for the most susceptible isolates, may be raised if the drug is added to broth that has become oxygenated during storage, or if drug-containing media are stored before inoculation. It is a poor substrate for tetracycline-specific efflux pumps, and it still attaches to ribosomes that have been modified by the Tet(M) protein. This antibacterial has demonstrated activity against a wide variety of gram-positive and gram-negative pathogens, including multidrug-resistant strains. It is active against many gram-positive and -negative organisms, including methicillin-resistantStaphylococcus aureus, vancomycin-intermediate and -resistant enterococci, and extended-spectrum β-lactamase–producing Escherichia coli and Klebsiella pneumoniae. This compound exhibits antibacterial activity against a wide spectrum of aerobic and anaerobic bacteria. It is a broad-spectrum, protein-inhibiting, antibacterial agent possessing activity against strains resistant to other chemotherapeutic agents. This chemical demonstrates in vitro activities against the GISA and the methicillin-resistant and methicillin-susceptible staphylococcal strains tested (MICs at which 90% of isolates tested are inhibited [MIC90s], 0.5 to 1 μg/ml). It has MIC90s of 0.25 μg/ml for all of the S. pneumoniae strains and demonstrates similar activities against all of the S. pneumoniae strains tested.

In vivo

Tigecycline is bactericidal against methicillin-susceptible S. aureus (MSSA) in the rabbit osteomyelitis model and exhibits good, but not excellent, activity in Legionellapneumophila pneumonia in guinea pigs. This compound at 50 mg/kg twice daily was not toxic to mice. It is effective in inhibiting NSCLC growth in vivo through decreasing proliferation and increasing apoptosis of tumor cells.
