L-Mycin, also known as Levomycin, is a broad-spectrum antibiotic with the chemical name D(-)-su-1-p-nitrophenyl-2-dichloroacetamido-1,3-propanediol, and D-threo-(-)-N-[α-(hydroxymethyl)-β-hydroxy-p-nitrophenethyl]-2,2-dichloroacetamide. Its CAS number is 56-75-7. The molecular formula is Câ‚â‚Hâ‚â‚‚Clâ‚‚Nâ‚‚Oâ‚…, and its molecular weight is 323.13. It is available in USP grade with a purity range of 97% to 103%. The specific optical rotation is between +17° and +20°, and it has a melting point ranging from 149°C to 153°C. When dissolved in water at 2.5%, the pH at 25°C is between 4.5 and 7.5.
This compound typically appears as white or yellowish needle-shaped crystals or a crystalline powder. It is slightly soluble in water (2.5 mg/mL at 25°C), slightly soluble in propylene glycol (150.8 mg/mL), and readily soluble in methanol, ethanol, butanol, and ethyl acetate. However, it is insoluble in ether, benzene, petroleum ether, and vegetable oil. The substance has a very bitter taste.
L-Mycin functions as an antibacterial agent by inhibiting protein synthesis at the peptidyl transferase step on the 50S ribosomal subunit. It is widely used in biochemical research for its antimicrobial properties. For storage, it should be kept at room temperature (RT) in a cool, dry place away from direct sunlight.
