diABZI-V/C-DBCO is a STING agonist with an EC50 of 1.47 nM. diABZI-V/C-DBCO activates the STING pathway, induces the production of IFN-I, and stimulates the secretion of IFN-β. diABZI-V/C-DBCO serves as a substrate for cathepsin B, and releases active diABZI-amine via cathepsin B-mediated cleavage. In an orthotopic mouse model of breast cancer, diABZI-V/C-DBCO increases serum IFN-β levels and the frequency of granzyme B+ CD8+ T cells. diABZI-V/C-DBCO is applicable to research related to triple-negative breast cancer.

Beschreibung

diABZI-V/C-DBCO is a STING agonist with an EC50 of 1.47 nM. diABZI-V/C-DBCO activates the STING pathway, induces the production of IFN-I, and stimulates the secretion of IFN-β. diABZI-V/C-DBCO serves as a substrate for cathepsin B, and releases active diABZI-amine via cathepsin B-mediated cleavage. In an orthotopic mouse model of breast cancer, diABZI-V/C-DBCO increases serum IFN-β levels and the frequency of granzyme B+ CD8+ T cells. diABZI-V/C-DBCO is applicable to research related to triple-negative breast cancer[1].

In Vitro

diABZI-V/C-DBCO (0.000001-100 μM, 24 h) activates the STING pathway in THP1-Dual cells with an EC50 of 1.47 nM, and induces the production of type I interferon (IFN-I)[1].
diABZI-V/C-DBCO (0.001-100 μM, 24 h) stimulates mouse splenocytes to secrete beta interferon (IFN-β), with an EC50 of 7.7 μM[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

ELISA Assay[1]

Cell Line: mouse splenocytes
Concentration: 0.001, 0.01, 1, 10, 100 μM
Incubation Time: 24 h
Result: Stimulated mouse splenocytes to secrete beta interferon (IFN-β), with an EC50 of 7.7 μM
In Vivo

diABZI-V/C-DBCO (0.68 mg/kg; i.v.; single/3 doses; once every 4 days) increases serum IFN-β levels and elevates the frequency of granzyme B+ CD8+ T cells in orthotopic breast cancer mouse models[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6 (female, 7 weeks old, EO771 breast cancer cell inoculation model)[1]
Dosage: 0.009 μmol/mouse (0.68 mg/kg)
Administration: i.v.; single dose/3 doses; once every 4 days
Result: Failed to significantly upregulate STING-related genes (Ifnb1, Cxcl10, Tmem173, Tnf, Il6) in tumor tissue relative to PBS control.
Increased serum IFN-β levels relative to PBS but lower than levels induced by SAPCon[100 kDa].
Increased the frequency of granzyme B+ CD8+ T cells relative to PBS.

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.
