Description

HDACs/EZH2-IN-1 (Compound 22a) is a HDACs/EZH2 inhibitor (EZH2 Y641N inhibition rate at 50 nM: 98%), with selective inhibition against HDAC1 and HDAC6 (IC50: 0.23 μM and 0.07 μM, respectively). HDACs/EZH2-IN-1 exerts a antiproliferative effect on diffuse large B-cell lymphoma cells harboring an EZH2 mutation and on various acute myeloid leukemia cells. HDACs/EZH2-IN-1 has the ability to induce cell differentiation and Apoptosis[1].

In Vitro

HDACs/EZH2-IN-1 (5 μM, 48-120 h) displays strong antiproliferative activities against SU-DHL-6 cells, which is a DLBCL cell line harboring EZH2 Y641N mutation, with IC50 of 1.04 μM (48 h) and 0.17 μM (120 h)[1].
HDACs/EZH2-IN-1 (0.1-100 μM 48 h) inhibits the growth of AML cells, with IC50 of 1.39 μM (MV4-11), 2.45 μM (U937), and 1.32 μM (OCI-AML3)[1].
HDACs/EZH2-IN-1 (4 μM, 6 h) increases the intracellular levels of the HDAC1/2/3 substrate acetylhistone H3 (AC-HH3) and the HDAC6 substrate acetyl-α-tubulin (AC-α-tubulin) [1].
HDACs/EZH2-IN-1 (2 μM, 48 h) induces differentiation of MOLM13 cells, with increasing expression of two myeloid maturation markers CD11b and CD14[1].
HDACs/EZH2-IN-1 (2-4 μM, 48 h) induces apoptosis of MOLM13 cells dose-dependently[1].
HDACs/EZH2-IN-1 (1-2 μM) synergizes with anti-AML compounds (Cytarabine (HY-13605), Daunorubicin (HY-13062A), Gilteritinib (HY-12432)) against cancer in MOLM13 cells[1].
HDACs/EZH2-IN-1 shows good metabolic stability in human and rat plasma, with T1/2 of >180 and 138 min, respectively[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.
