产品描述:
Toyocamycin is a natural adenosine analog first isolated from Streptomyces and shown in early studies to be cytotoxic to bacteria, fungi, and cancer cells and to have antiviral activities. Toyocamycin prevents IRE1α-induced mRNA cleavage (IC50 = 80 nM) and inhibits constitutive activation of XBP1 in multiple myeloma cell lines.{31592} It is used to study IRE1α action in the endoplasmic reticulum stress response, particularly in the context of cancer.{31589,31593} It also inhibits phosphatidylinositol kinase in vitro (IC50 = 3.3 µg/ml), but not in cells, and blocks the ribosomal RNA-processing kinase Rio1 (IC50 = ~30 nM).{31591,31590}
