Application

Trapoxin A has been used:
  • to study its effects on the inhibition of histone deacetylase 11 (HDAC11)
  • to study its effects on the inhibition of HDAC3 in human cell lines
  • to study its effects on the inhibition of HDAC6 in rat pyramidal neurons

Biochem/physiol Actions

Trapoxin A is a cyclotetrapeptide and a histone deacetylase (HDAC) inhibitor. It increases the level of chromatin acetylation associated with histone H3 at low nanomolar concentrations. Unlike the reversible HDAC inhibition induced by TCA, Trapoxin A irreversibly inhibites HDAC activity in crude cell lysates, and induces the accumulation of hyperacetylated core histones in a number of mammalian cell lines and tissues. Histone acetylation and methylation have been studied extensively for their anti-tumor activities in carcinogenesis and Trapoxin has been suggested as a potential anticancer agent for pre-clinical trials.
