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.

: Toyocamycin purchased from MedChemExpress. Usage Cited in: Am J Pathol. 2023 Sep;193(9):1284-1297. [Abstract]; Bar plots showing the fold-changes at selected Toyocamycin (0-40 nmol/L) concentrations at 72 hours after treatment.

: Toyocamycin purchased from MedChemExpress. Usage Cited in: Am J Pathol. 2023 Sep;193(9):1284-1297. [Abstract]; To investigate the underlying mechanism of Toyocamycin-related toxicity in PCa cells, short-term experiments (24 hours) in PC3 and 22Rv1 cells at a concentration of 100 nmol/L were performed. To differentiate between Toyocamycin-specific and general cell death related alterations, the clinically used chemotherapeutic drug docetaxel (100 nmol/L) was included in these experiments. RIOK1 protein expression was significantly reduced within 24 hours after biochemical inhibition of RIOK1, which might indicate that RIOK1 auto-activates its own expression, as observed in budding yeast.

: Toyocamycin purchased from MedChemExpress. Usage Cited in: Am J Pathol. 2023 Sep;193(9):1284-1297. [Abstract]; The impact of Toyocamycin on rRNA content was measured, given the importance of RIOK1 in the production of rRNA and in the processing of the 18S-E pre-rRNA. Total rRNA content per cell was significantly reduced, by >30%, in both cell lines.

: Toyocamycin purchased from MedChemExpress. Usage Cited in: Am J Pathol. 2023 Sep;193(9):1284-1297. [Abstract]; To assess whether Toyocamycin induces apoptosis in PCa cells, the sub-G1 fraction was measured in PC3 and 22Rv1 cells using fluorescence-activated cell sorting analysis after 72 hours of Toyocamycin treatment, and the effect was compared to that with docetaxel treatment. With the two drugs at a concentration of 100 nmol/L, apoptosis was significantly induced at 72 hours after treatment.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
