Biochem/physiol Actions

Studies have implicated that toyocamycin blocks the replication of fowl plague virus.
Toyocamycin is a nucleoside- type antibiotic analogue of adenosine, isolated from Streptomyces species. Toyocamycin is an anti-tumor antibiotic with various target activities. Toyocamycin is a potent inhibitor of RNA self-cleavage in mammalian cells. It also inhibits phosphatidylinositol kinase, a cell proliferation regulator. Toyocamycin was also found to inhibit Auxin signaling. Auxins are plant hormones with a crucial role in plant development regulation, and Toyocamycin was found to specifically inhibit auxin-responsive gene expression.

Preparation Note

Toyocamycin is soluble in DMSO at 0.90 - 1.10 mg/ml and yields a clear, colorless solution. It is also soluble in acidic solutions and is moderately soluble in water, methanol and ethanol. Solutions prepared in DMSO can be diluted 10-fold in water.
