Description

STL127705 (Compound L) is a potent Ku 70/80 heterodimer protein inhibitor with an IC50 of 3.5 μM. STL127705 interferes the binding of Ku70/80 to DNA and by inhibits the activation of the DNA-PKCS kinase. STL127705 shows antiproliferative and anticancer activity. STL127705 induces apoptosis[1][2].

IC50 & Target

IC50: 3.5 μM (Ku 70/80), 2.5 μM (DNA-PKCS)[1]
In Vitro

STL127705 (Compound L) (0-100 μM) inhibits binding of Ku70/80 to a DNA substrate and inhibits Ku-dependent activation of the DNA-PKCS kinase[1].
? STL127705 (0-100 μM; 6h) decreases the expression of DNA-PKCS auto-phosphorylation in SF-767 cells[1].
? STL127705 (0-40 μM; 6h) shows antiproliferative activity in a dose dependent manner[1].
? TL127705 (1 μM; 48 h) significantly promotes apoptotic when combination with gemcitabine[2].

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.
