VPA (Valproic acid)

VPA (Valproic acid) is a fatty acid with anticonvulsant properties used in the treatment of epilepsy. It is also a histone deacetylase (HDAC) inhibitor and is under investigation for treatment of HIV and various cancers. Valproic acid (VPA) induces autophagy and mitophagy by upregulation of BNIP3 and mitochondrial biogenesis by upregulating PGC-1α. Valproic acid activates Notch-1 signaling.

製品説明

VPA (Valproic acid) is a fatty acid with anticonvulsant properties used in the treatment of epilepsy. It is also a histone deacetylase (HDAC) inhibitor and is under investigation for treatment of HIV and various cancers. Valproic acid (VPA) induces autophagy and mitophagy by upregulation of BNIP3 and mitochondrial biogenesis by upregulating PGC-1α. Valproic acid activates Notch-1 signaling.

Targets

HDAC ^[1]	HDAC1 ^[1] (Cell-free assay)
	0.4 mM

In Vitro
In vitro	Valproic acid (VPA), like lithium, activates Wnt-dependent gene expression, but unlike lithium, VPA does not inhibit GSK-3β in vivo. VPA can inhibit GSK-3β-mediated phosphorylation of a CREB peptide in vitro. VPA may activate Wnt-dependent gene expression through inhibition of HDAC, which in turn leads to both increased expression of β-catenin and de-repression of Tcf/Lef (as well as activation of other HDAC-regulated genes). In vitro, VPA can stimulate glutamic acid decarboxylase, which is involved in GABA biosynthesis, and inhibit GABA transaminase, succinic semialdehyde dehydrogenase, and α-ketoglutarate dehydrogenase, enzymes involved in GABA degradation^[1]. Valproic acid relieves HDAC-dependent transcriptional repression and causes hyperacetylation of histones in cultured cells and in vivo. VPA induces differentiation and/or apoptosis of carcinoma cells, PML-RAR-transformed hematopoietic progenitor cells and leukemic blasts from AML patients^[2]. In addition to selectively inhibiting the catalytic activity of class I HDACs, VPA also induces proteasomal degradation of HDAC2^[3].
細胞実験	細胞株	Neuro2A cells
	濃度	0.5-5 mM
	反応時間	24 h
	実験の流れ	Neuro2A cells are treated with VPA (0.5-5 mM) or with TSA (300 nm) for 24 h and then histones are isolated. Histone acetylation is assessed by immunoblotting with an antibody specific to acetylated histone H4.

In Vivo
In Vivo	Valproic acid (VPA) increases the level of the inhibitory neurotransmitter γ-aminobutyric acid (GABA), with acute administration causing a 15-45% increase in GABA in the brains of rodents^[1]. VPA also inhibits tumor growth and metastasis in animal experiments. It is a well-tolerated drug even during long-term treatment^[2].
