Description

Tylosin A, EvoPure®is a highly purified (>99.00% pure) form of tylosin A. Tylosin is a macrolide antibiotic that was originally isolated from Streptomyces fradiae by the Lilly Research Laboratories in 1961 from a soil sample collected in Thailand. Tylosin is a mixture of four macrolide antibiotics, the main component of the mixture (> 80%) is tylosin A; tylosin B (desmycosin), tylosin C (macrocin), and tylosin D (relomycin) may also be present.  Tylosin has broad spectrum bacteriostatic activity against gram-positive bacteria and mycoplasma, but much less activity against most gram-negative bacteria and fungi.

Tylosin A contains a polyketide lactone (tylactone) substituted with three 6-deoxyhexose sugars. The addition of D-mycaminose to the aglycone is followed by concurrent ring oxidation at C-20 and C-23 (to generate the tylonolide moiety) and substitution with L-mycarose and 6-deoxy-Dallose.

Tylosin, like other Macrolide antibiotics, is a bacteriostatic compound that reversibly bind to the 23S rRNA in the 50S (L27 protein) ribosome subunit and inhibit mRNA-directed protein synthesis.

Tylosin has been used to study protein synthesis, abscess prevention in cattle, and Mycoplasma infections.

    CAS Number

    8026-48-0

    Molecular Formula

    C46H77NO17

    Molecular Weight

    916.10

    Mechanism of Action

    Tylosin A binds to the 50S ribosomal subunit interfering with the binding of aminoacyl-tRNA-to 50S and block peptide bond formation. This inhibits the translocation of a newly synthesized peptidyl tRNA molecule from the acceptor site to the peptidyl site.
