Summary
Valproic acid (VPA) is an orally active HDAC inhibitor, with IC 50 in the range of 0.5 and 2 mM, also inhibits HDAC1 ( IC 50 , 400 μM), and induces proteasomal degradation of HDAC2 . Valproic acid activates Notch1 signaling and inhibits proliferation in small cell lung cancer (SCLC) cells. Valproic acid is used in the treatment of epilepsy, bipolar disorder, metabolic disease , HIV infection and prevention of migraine headaches [1] [2] [3] [4] [5] [6] [7] .

In Vitro
Valproic acid (VPA) (0-15 mM; 24 and 72 h) inhibits Hela cell growth in a dose- and time- dependent manner
[1]
.
Valproic acid (10 mM; 24 h) significantly attenuates the activities of total, cytosol and nuclear HDACs
[1]
.
Valproic acid (0-15 mM; 24 h) induces a G1 phase arrest at 1–3 mM and a G2/M phase arrest at 10 mM, and increases the percentage of sub-G1 cells in HeLa cells. Valproic acid also induces necrosis, apoptosis and lactate dehydrogenase (LDH) release
[1]
.
Valproic acid (0-20 mM; 24 h) activates Tcf/Lef-dependent transcription and synergizes with lithium
[2]
.
Valproic acid (0-5 mM; 0-18 h) increases β-catenin levels in Neuro2A cells
[2]
.
Valproic acid (0-2 mM; 0-24 h) stimulates phosphorylation of AMPK and ACC in hepatocytes
[5]
.
Valproic acid (0-10 mM; 2 days) induces Notch1 signaling and morphologic differentiation, suppresses production of NE tumor markers in SCLC cells
[6]
.

[5]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
| Animal Model: | Female BALB/c nude mice, Kasumi-1 tumor model [3] |
| Dosage: | 500 mg/kg |
| Administration: | Intraperitoneal injection, daily for 12 days |
| Result: |
Inhibited tumor growth and tumor angiogenesis.
Inhibited the mRNA and protein expression of VEGF, VEGFR2 and bFGF. Inhibited HDAC activity and increased acetylation of histone H3. Enhanced the accumulation of hyperacetylated histone H3 on VEGF promoters. |
| Animal Model: | Timed-pregnant Long Evans rats [4] |
| Dosage: | 350 mg/kg |
| Administration: | Intraperitoneal injection, once |
| Result: | Demonstrated more social investigation and play fighting than control animals. |
| Animal Model: | Obese phenotype of ob/ob mice [5] |
| Dosage: | 0.26% (w/v) |
| Administration: | Oral via drinking water, 14 days |
| Result: | Revealed a marked reduction in the accumulation of fats in the liver as compared with the untreated mice, significantly decreased liver mass to body mass, decreased serum triglyceride concentrations, and did not induce hepatotoxicity. |
