Description

GMB-805 is a BCR-Abl PROTAC degrader with a DC50 of 30 nM in K562 cells. GMB-805 exerts antiproliferative activity in K562 cells. GMB-805 exhibits potent anti-tumor activity with favorable safety profile in vivo. GMB-805 can be used for chronic myeloid leukemia research[1][2].

IC50 & Target[1]

Bcr-Abl

30 nM (DC50)

In Vitro

GMB-805 (1-30000 nM, 24 h) dose-dependently degrades BCR/Abl protein in K562 cells with a DC50 of 30 nM in K562 cells[1].
GMB-805 (1 μM, 8 h) induces BCR/Abl protein degradation via the proteasome in K562 cells[1].
GMB-805 (1000 nM, 24 h) reduces VHL-dependent BCR/Abl and c-Abl protein levels in K562 cells[1].
GMB-805 (3 days) possesses potent antiproliferative activity against the BCR-Abl driven cell line K562 with an IC50 of 169 nM[1].

Western Blot Analysis[1]

Cell Line: K562 cells
Concentration: 25, 250 and 2500 nM
Incubation Time: 24 h
Result: Demonstrated an enhanced ability to induce BCR-Abl degradation.

Western Blot Analysis[1]

Cell Line: K562 cells
Concentration: 1 μM
Incubation Time: 8 h
Result: Reduced BCR-Abl and Abl protein expression, and this effect was rescued by cotreatment with Epoxomicn (1 μM) (HY-13821).
Reduced BCR-Abl and Abl protein expression, and this effect was not rescued by cotreatment with Chloroquine (50 μM) (HY-17589A).
Reduced BCR-Abl and Abl protein expression, and this effect was rescued by cotreatment with Pevonedistat (1 μM) (HY-70062).

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.
