ActiTarg-H, HDAC Inhibitors

Histone deacetylase (HDAC) inhibitors are compounds that modulate the function of histone deacetylase and are divided into four classes.  HDAC determines the acetylation status of histones and controls the regulation of gene expression.

Histone deacetylases present lucrative targets and their inhibitors display wide range of epigenetic activities opening the doorway for therapeutic approaches to good number of health conditions, among others, involving central nervous system, cancers, diabetes.

TimTec collection of HDAC inhibitors gathers 1,700 compounds-analogs to known HDAC approved therapies across all classes. These are the structures with the same fragments, scaffolds, and the overall molecular similarity. ActiTarg-H compound pool is available for cherry-picking and is offered in custom formatting if you are interested in a subset. Structural files are available for preview prior to purchase – please inquire.

As a partial example, the following well-known molecules were included in ActiTarg-H design consideration: PCI-24781, PCI-34051, Erlotinib, CUDC-101, Entinostat, Trichostatin, LAQ 824, Panobinostat, Belinostat, Apicidin, Romidepsin, Vorinostat, Abexinostat, Valproic acid, Trichostatin A, Mocetinostat, Givinostat, Quisinostat, Sulforaphane, Pracinostat, hydroxamic acids, cyclic peptide mimic.
