General description

A novel anti-neoplastic agent and transcriptional regulator. Also acts as an inducer of tumor cytostasis and differentiation. Increases fetal hemoglobin production in vitro and in vivo.
An antineoplastic agent that demonstrates potent differentiating capacity in multiple hematopoietic and solid tumor cell lines. Acts as an inducer of tumor cytostasis and differentiation as well as of peroxisomal proliferation. A more effective inhibitor of histone deacetylase and inducer of histone acetylation than its structural analogs including 2- and 3-phenylbutyrate. Acts as a transcriptional regulator and improve the targeting of δF508-CFTR (cystic fibrosis transmembrane regulator) for ubiquitination and degradation by reducing the expression of HSC70 in epithelial cells. Also, reported to increase fetal hemoglobin production in vitro and in vivo.
