Description

Mcl-1 inhibitor 6 is an orally active, selective myeloid cell leukemia 1 (Mcl-1) protein inhibitor with a Kd of 0.23 nM and a Ki of 0.02 μM. Mcl-1 inhibitor 6 possesses superior selectivity over other Bcl-2 family members (Bcl-2, Bcl2A1, Bcl-xL, and Bcl-w, Kd>10 μM). Mcl-1 inhibitor 6 is a potent antitumor agent[1].

In Vitro

Mcl-1 inhibitor 6 has Kis of 10 μM and 1.57μM for Bcl-2 and Bfl-1, respectively[1].
Mcl-1 inhibitor 6 (1, 5 μM; for 48 h) significantly induces apoptosis in a concentration-dependent manner[1].
Mcl-1 inhibitor 6 (0.1, 5 μM; for 4 h) remarkably upregulates PARP cleavage in H929 cells in a concentration-dependent manner[1].
Mcl-1 inhibitor 6 (for 72 h) shows antiproliferative activities against the tumor cell lines (H929, MV4-11, SK-BR-3, NCI-H23; IC50=0.36-3.02 μM). Mcl-1 inhibitor 6 shows ideal selectivity against CML cell line K562 (IC50>30 μM)[1].

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.
