|Description||Valproic acid is a fatty acid with anticonvulsant properties used in the treatment of epilepsy. It is also a histone deacetylase inhibitor and is under investigation for treatment of HIV and various cancers.|
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. 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. In addition to selectively inhibiting the catalytic activity of class I HDACs, VPA also induces proteasomal degradation of HDAC2.
|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. VPA also inhibits tumor growth and metastasis in animal experiments. It is a well-tolerated drug even during long-term treatment.|

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
