Description

Actinonin ((-)-Actinonin) is a naturally occurring antibacterial agent produced by Actinomyces. Actinonin inhibits aminopeptidase M, aminopeptidase N and leucine aminopeptidase. Actinonin is a potent reversible peptide deformylase (PDF) inhibitor with a Ki of 0.28 nM. Actinonin also inhibits MMP-1, MMP-3, MMP-8, MMP-9, and hmeprin α with Ki values of 300 nM, 1, 700 nM, 190 nM, 330 nM, and 20 nM, respectively. Actinonin is an apoptosis inducer. Actinonin has antiproliferative and antitumor activities.

How to use

In Vitro:

Actinonin inhibits cell growth in various human tumor cell lines. The IC50 of 4, 6.9, 12.8, 16.6, 27.4, 15.7 and 49.3 μM for Raji cells, MDA-MB-468 cells, PC3 cells, SK-LC-19 cells, Hela cells, HT-1080 cells and AL67 cells, respectively. HsPDF is a critical target of actinonin and that the inhibition of this protein in the mitochondria leads to cell death in tumor cells. Actinonin treatment of cells led to a tumor-specific mitochondrial membrane depolarization and ATP depletion in a time- and dose-dependent manner. Actinonin is a potent inhibitor of all three forms (Zn-, Ni-, and Fe-) of peptide deformylases from both S. aureus and E. coli bacteria. Under the assay conditions, the IC50 values for Actinonin are 90, 3, 0.8, and 11 nM for Zn-PDF (E. coli), Ni-PDF (E. coli), Fe-PDF (E. coli), and Ni-PDF (S. aureus), respectively. Actinonin is active against Gram-positive bacteria, including S. aureus (MIC value of 8-16 µg/mL), Streptococcus pyogenes (MIC value of 8 µg/mL) and Streptococcus epidermidis (MIC value of 2-4 µg/mL). Actinonin is also active against fastidious Gramne-gative bacteria, such as H. influenzae (MIC value of 1-2 µg/mL), Moraxella catarrhalis (MIC value of 0.5 µg/mL), and Neisseria gonorrheae (MIC value of 1-4 µg/mL). Actinonin is very active against the H. influenzae acr (MIC value of 0.13 µg/mL) and E. coli acr (MIC value of 0.25 µg/mL) efflux pump mutants.

In Vivo:

Actinonin has been safely administered to mice as an antibiotic at doses up to 400 mg/kg. Actinonin does not appear to have significant toxicity to normal tissues, despite its antitumor activity in vitro. Remarkably, Actinonin exhibits significant antitumor activity when given i.p. or orally in a CWR22 human prostate tumor xenograft model in nude mice. During treatment, the animals show no signs of toxicity.
