Application

Oxamflatin has been used as a histone deacetylase (HDAC) inhibitor:
  • to study its effect on specificity protein 1 (Sp1) transcription and transactivation activity and CD1d mRNA expression in various tumor cells
  • to study its inhibitory effect on long transcript- survival motor neuron gene 2 (SMN2) silencing mediated by DNA methylation
  • to study its effect on somatic embryogenesis in Coffea arabica thorough a miniaturized and automated screening system
  • to study its stand-alone effect on cytarabine-sensitive and resistant cells.

Biochem/physiol Actions

Oxamflatin is an aromatic sulfonamide derivative with a hydroxamic acid group. It stimulates the expression of the transcription factor, JunD, and fibronectin. In addition, oxamflatin also aids in the morphological reversion of various NIH3T3-derived transformed cell lines. It inhibits the proliferation of various mouse and human tumor cell lines in vitro.
Histone deacetylase inhibitor; anti-cancer agent.
