Description

CDK/HDAC-IN-3 is an orally active HDACs/CDKs dual inhibitor. CDK/HDAC-IN-3 has potent and selective inhibition of CDK9, CDK12, CDK13, HDAC1, HDAC2 and HDAC3 with IC50 values of 98.32 nM, 98.85 nM, 100 nM, 62.12 nM, 93.28nM and 82.87 nM. CDK/HDAC-IN-3 can be used for the acute myeloid leukemia (AML) [1].

IC50 & Target

IC50: 98.32 nM (CDK9), 98.85 nM (CDK12), 100 nM (CDK13), 62.12 nM (HDAC1), 93.28nM (HDAC2) and 82.87 nM (HDAC3), 0.72 μM (U937 cell), 1.43μM (HL-60 cell), 1.63μM (SKNO-1 cell) and 0.89 μM (Kaumi-1 cell)[1].

In Vitro

CDK/HDAC-IN-3 (compound 33a) (1μM) has potent and selective inhibition of CDK9, CDK12, CDK13, HDAC1, HDAC2 and HDAC3 with IC50 values of 98.32 nM, 98.85 nM, 100 nM, 62.12 nM, 93.28nM and 82.87 nM, respectively[1].
CDK/HDAC-IN-3 (0.5 μM, 1.0 μM) significantly induces differentiation of leukemic stem-like cells and inhibits AML proliferation[1].
CDK/HDAC-IN-3 (0.5 μM, 1.0 μM, 2.0 μM) significantly induced differentiation of LSCs[1].
CDK/HDAC-IN-3 has inhibitory effect for U937, HL-60, SKNO-1 and Kaumi-1 cell with IC50 values of 0.72 μM, 1.43μM, 1.63μM and 0.89 μM, 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.
