Structure-activity relationship studies of valproic acid (VPA) derivatives have revealed a quantitative correlation between histone deacetylase (HDAC) inhibition and induction of neural tube defects (NTDs) in the NMRI-exencephaly-mouse model, but this correlation has been, so far, limited to congeners with a carboxylic acid function. Whereas the classical HDAC inhibitor trichostatin ...

CYP4B1 belongs to the mammalian CYP4 enzyme family that also includes CYP4A, 4F, 4V, 4X, and 4Z subfamilies. CYP4B1 shares with other CYP4 proteins a capacity to omega-hydroxylate medium-chain fatty acids, which may be related to an endogenous role for the enzyme. CYP4B1 also participates in the metabolism of certain ...

Valproic acid (sodium valproate) is widely used as a first-line antiepileptic agent. As with many antiepileptic drugs, there are a number of consequences associated with the use of valproic acid in women of child-bearing potential. Most pregnancies have a favourable outcome in women with epilepsy, and these women should not ...

Valproic acid (2-n-propylpentanoic acid; VPA) has several therapeutic indications, but it is used primarily as an anticonvulsant. VPA is a relatively safe drug, but its use is associated with idiosyncratic hepatotoxicity, which in some cases may lead to fatality. The underlying mechanism responsible for the hepatotoxicity is still not well ...

Valproic acid, a commonly used antiepileptic agent, is associated with a 1 to 2% incidence of neural tube defects when taken during pregnancy; however, the molecular mechanism by which this occurs has not been elucidated. Previous research suggests that valproic acid exposure leads to an increase in reactive oxygen species ...

Valproic acid (VPA), an anticonvulsant and mood-stabilizing drug, has been reported to exert neuroprotection against a variety of insults. We now show that VPA attenuates rotenone (a potent complex I inhibitor)-induced apoptosis through the induction of heat shock protein 70, which may interact with apoptotic-protease-activating factor 1. Activation of p-Akt, ...

In utero exposure to valproic acid (VPA) during pregnancy is associated with an increased risk of neural tube defects (NTDs). Although the mechanism by which VPA mediates these effects is unknown, VPA-initiated changes in embryonic protein levels have been implicated. The objectives of this study were to investigate the effect ...

There have been many recent developments in the pharmacological management of alcohol withdrawal and alcohol dependence. Although previous treatments had included benzodiazepines as their mainstay, the use of these agents in the alcoholic population is problematic. Benzodiazepines are themselves addictive and they may increase the risk of alcohol relapse. Non-benzodiazepine ...

Rice polishing is a by-product of rice milling. It is a good source of energy and an assortment of amino acids. The anti-nutritive factors associated with rice polishing reduce the availability of amino acids and other nutrients to poultry. Defatted rice polishing (DRP) was chemically treated with 0.4N HCl and ...
