Telavancin hydrochloride
Based on 1 publication(s) in Google Scholar
Telavancin hydrochloride (TD-6424 hydrochloride) is a bactericidal agent that exhibits inhibitory activity against Staphylococcus aureus. Telavancin hydrochloride inhibits bacterial cell wall synthesis by binding to the lipid-linked N-acetylglucosamine-N-muramyl pentapeptide (with a D-Ala-D-Ala terminus), a peptidoglycan precursor, and blocks the transglycosylation and transpeptidation steps. Telavancin hydrochloride disrupts bacterial membrane barrier function, induces dissipation of bacterial membrane potential, and causes leakage of cytoplasmic ATP and potassium ions, with its activity restricted exclusively to bacterial membranes. Telavancin hydrochloride can be used in research on bacterial infections, central venous catheter-related bloodstream infections, and Gram-positive bacterial pneumonia.

Biological Activity
Description
In Vitro
Telavancin hydrochloride (TD-6424 hydrochloride) exerts rapid, concentration-dependent bactericidal activity against extracellular and intracellular MRSA, MSSA, VISA, β-haemolytic streptococci, and viridans group streptococci in vitro, with a ≥3 log10 reduction in cfu/mL achieved at multiples of the MIC within 8-24 hours[1].
Telavancin hydrochloride exhibits a post-antibiotic effect of 0.3-3.9 hours against MRSA, streptococci, and Vancomycin (HY-B0671)-susceptible enterococci in vitro[1].
Telavancin hydrochloride achieves a ≥3 log10 reduction in MRSA and MSSA cfu/mL in vitro, including activity against nongrowing bacteria[1].
Telavancin hydrochloride displays potent in vitro activity against a broad range of gram-positive bacteria, including drug-resistant S. aureus strains, with MIC90 values ranging from 0.03 μg/mL (for S. pneumoniae) to 8 μg/mL (for Van A enterococci)[3].
Telavancin hydrochloride has bactericidal activity against S. aureus biofilms (including VISA strains) in a Sorbarod model[3].
Telavancin hydrochloride induces rapid, concentration-dependent bacterial membrane depolarization and cytoplasmic leakage, with specificity for bacterial rather than mammalian membranes[3].
Telavancin hydrochloride exhibits in vitro synergy with Gentamicin (HY-A0276A) and Rifampin (Rifampicin) (HY-B0272) against S. aureus[3].
Telavancin (2-5 mg/mL; 72 h at 37 °C) hydrochloride maintains >90% of its initial concentration and physical compatibility when combined with Heparin Sodium (Heparin sodium salt) (HY-17567A) 2500 units/mL, TSC 22 mg/mL, or TSC 40 mg/mL over 72 hours at 37 °C[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Telavancin (10 mg/kg; i.v.) demonstrates greater efficacy than vancomycin in reducing blood and spleen bacterial titers in immunocompromised mice with MRSA or VISA bacteremia[3].
Telavancin hydrochloride is highly bactericidal against penicillin-resistant Streptococcus pneumoniae in a rabbit meningitis model, producing a 6.12 log reduction in CSF bacterial counts and sterilizing CSF in 60% of treated rabbits[3].
Telavancin (30 mg/kg; every 12 h; 4 weeks) sterilizes 80% of tibial S. aureusMRSA osteomyelitis infections in rabbits[3].
