HDAC-IN-53 is an orally active, and selective HDAC1-3 inhibitor with IC₅₀ values of 47 nM, 125 nM, and 450 nM, respectively. HDAC-IN-53 does not inhibit class II HDACs (HDAC4, 5, 6, 7, 9; IC₅₀>10 μM). HDAC-IN-53 induces caspase-dependent apoptosis. HDAC-IN-53 significantly inhibits the growth of human tumor xenografts in nude mice and murine tumor growth in immune-competent mice bearing MC38 colon cancer.

In Vitro

HDAC-IN-53 (compound 19h) has good antiproliferative activity against a panel of cancer cell lines, for example MC38 (IC₅₀=0.66 μM), HCT116 cell (IC₅₀=0.56 μM) ^[1].
HDAC-IN-53 (0.1-1 μM; 24 h) causes G0/G1 cell cycle arrest in MC38 cells and induces G2/M cell cycle arrest in HCT116 cells^[1].
HDAC-IN-53 (0.1-1 μM; 24 h) upregulates the expressions of cleaved caspase-3 and cleaved PARP in a dose-dependent manner^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
