Product Description: Toyocamycin (Vengicide) is an adenosine analog produced by Streptomyces diastatochromogenes, acts as an XBP1 inhibitor. Toyocamycin blocks RNA synthesis and ribosome function, and induces apoptosis. Toyocamycin affects IRE1α-XBP1 pathway, and inhibits XBP1 mRNA cleavage with an IC50 value of 80 nM with affecting IRE1α auto-phosphorylation. Toyocamycin specifically inhibits CDK9 with an IC50 value of 79 nM[1][2][3].
Applications: Cancer-Kinase/protease
Formula: C12H13N5O4
