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.

We constructed an assay system of a luciferase reporter with p16/lNK4a gene transcriptional regulatory domain to identify p16-inducing substances, and found toyocamycin to induce gene expression from the screening of culture fluids of Streptomyces. Toyocamycin is a nucleoside analog, and

Toyocamycin and some analogues have shown potent antitumor activities; however, none of them could be used clinically primarily owing to their cytotoxicity to normal human cells. In order to overcome the weakness of these nucleoside analogues, substitution of a variety

The ability to control expression of a specific gene is a prerequisite to understand the function of essential genes. Many gene regulation systems operate on the transcriptional level by employing heterologous cis- and trans-acting elements. Recently, novel approaches employing autocatalytic

Recent studies on the control of specific metabolic pathways in bacteria have documented the existence of entirely RNA-based mechanisms for controlling gene expression. These mechanisms involve the modulation of translation, transcription termination or RNA self-cleavage through the direct interaction of
