CAS Number

1404-93-9

Molecular Formula

C₆₆H₇₅Cl₂N₉O₂₄ · HCl

Molecular Weight

1485.71

Mechanism of Action

Vancomycin prevents peptidoglycan synthesis by two separate mechanisms. One mechanism prevents N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) from linking together forming the peptidoglycan backbone. The second mechanism prevents crosslinking between amino acid residues in the peptidoglycan chain.

Storage Conditions

2-8°C, protect from light

Tariff Code

2941.90.5000

Spectrum

Vancomycin inhibits growth of many Gram positive bacteria including the antibiotic resistant superbug, MRSA (Methicillin resistant Staphylococcus aureus). Vancomcyin is effective for treating MRSA infections because it inhibits cell wall synthesis through a different mechanism than β-lactam antibiotics.

Applications

Microbiology Applications

Vancomycin HCl, USP is commonly used in selective media for isolation of Gram-negative pathogens including Campylobacter jejuni, Escherichia coli, Haemophilus influenzae, Helicobacter pylori, and Neisseria gonorrhoeae. superbug vancomycin resistant enterococcus (VRE) detection. Representative MIC values include:

Methicillin resistant Staphylococcus aureus (MRSA) 0.25 µg/mL - 2 µg/mL
Clostridium difficile 0.06 µg/mL - 4 µg/mL

Plant Biology Applications

Vancomycin is often used in Agrobacterium mediated transformations to control bacterial growth and shows a synergistic effect when used in combination with cefotaxime. Vancomycin does not appear to have any negative effects on plants; however, a study by Silva and Fukai (2001) observed a lower transformation efficiency when >500 µg/ml was used.
