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.

Spinal muscular atrophy (SMA), a common neuromuscular disorder, is caused by homozygous absence of the survival motor neuron gene 1 (SMN1), while the disease severity is mainly influenced by the number of SMN2 gene copies. This correlation is not absolute

CD1d is a MHC class-like molecule that presents glycolipids to natural killer T (NKT) cells, then regulates innate and adaptive immunity. The regulation of CD1d gene expression in solid tumors is still largely unknown. Gene expression can be epigenetically regulated

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Histone Modification and Chromatin Remodeling | Epigenetics

Epigenetic modifications are thought to occur through two key interconnected processes—DNA methylation and the covalent modification of histones.
