Biochem/physiol Actions

Pactamycin is a potent protein synthesis inhibitor, inhibiting protein synthesis at the translocation step on the 70S ribosome. It has activity against Gram-positive and Gram-negative bacteria, and broad antitumor, antiviral, and antiplasmodial activity. Cytotoxicity limits it clinical use.
