Application

  • In yeast cells, doxycycline has been used in doxycycline-inducible system for overexpression of methyltransferase Hmt1 (hnRNP methyltransferase 1).
  • It has been used in the doxycycline-inducible IFITM (interferon-induced transmembrane) cell lines.
  • It has also been used as an antimicrobial agent.

Biochem/physiol Actions

Doxycycline is a semisynthetic tetracycline that is active against bacteria, mycoplasma and protozoan parasites. It inhibits the bacterial protein synthesis by inhibiting the interaction of aminoacyl-tRNA and the bacterial ribosome.
