Tacedinaline Usage And Synthesis

Description

CI-994 (112522-64-2) is an orally active histone deacetylase (HDAC) inhibitor, IC50 = 0.9, 0.9, 1.2 and >20 μM for HDAC1, HDAC2, HDAC3 and HDAC8 respectively.1 Mediates G1 cell cycle arrest, inhibits proliferation and induces apoptosis in vitro and in vivo.2,3 Increases neuroplasticity during memory extinction.4 Protects beta cells from cytokine-induced apoptosis.4

Uses

Tacedinaline is a histone deacetylase (HDAC) inhibitor. Tacedinaline is an anti-cancer agent as HDAC inhibitors block angiogenesis, arrest cell growth, and lead to differentiation and apoptosis in tumor cells. Studies show Tacedinaline to be effective against acute myeloid leukemia in vitro and in vivo when used in combination with conventional anti-cancer agents.

Definition

ChEBI: A benzamide obtained by formal condensation of the carboxy group of 4-acetamidobenzoic acid with one of the amino groups of 1,2-phenylenediamine. An oral cytostatic drug with impressive differential activity against leukemic cells and normal stem-cells. Al o used in combination therapy for selected tumors including non-smoll cell lung, pancreatic, breast, and colorectal cancers.

Biological Activity

Orally active histone deacetylase (HDAC) inhibitor (K i values are 0.41, 0.75, >100 and >100 μ M for HDAC1, HDAC3, HDAC6 and HDAC8 respectively). Mediates G 1 cell cycle arrest, inhibits proliferation and induces apoptosis in vitro and in vivo .
