Catalog Number: 2682
Alternate Names: 4-PB, Sodium phenylbutyrate
Chemical Name: 4-Phenylbutyric acid, sodium salt
Biological Activity
Histone deacetylase inhibitor that displays anticancer activity. Inhibits cell proliferation, invasion and migration and induces apoptosis in glioma cells. Also inhibits protein isoprenylation, depletes plasma glutamine, increases production of fetal hemoglobin through transcriptional activation of the γ-globin gene and affects hPPARγ activation.
