The efficacy of the antiepileptic drug VPA is decreased by co-administered carbapenems (CBPMs). The mechanism of CBPM selective inhibition of acylpeptide hydrolase (APEH) hydrolysis of VPA-glucuronide (VPA-G) to VPA is unclear due to the lack of APEH structural information. Here we performed homology modeling of the three-dimensional structure of APEH and subsequent docking simulations with a modeled structure to understand this mechanism. Docking simulations indicated that four groups of binding structures were involved in the binding of VPA-G, panipenem, and meropenem to APEH, but only one or two binding structures were involved in the binding of meropenem with an open β-lactam ring structure and other antibiotics involving ampicillin...

Valproic acid (VPA)-exposed rat offspring have demonstrated autism spectrum disorder (ASD) phenotypes and impaired N-methyl-D-aspartate receptor (NMDAR)-dependent long-term depression (LTD) in the lateral nucleus of the amygdala. NMDAR partial agonist D-cycloserine (DCS) has been reported to act as a cognitive enhancer by increasing the NMDAR response to improve autistic-like phenotypes in animals. However, the mechanism of DCS in alleviating the ASD is still unknown. Using combined behavioral, electrophysiological, and molecular approaches, we found that DCS administration rescued social interaction deficits and anxiety/repetitive-like behaviors observed in VPA-exposed offspring...

BACKGROUND: Drug-induced gingival hyperplasia (DIGH) causes problems with chewing, aesthetics, and pronunciation, and leads to the deterioration of the patient's quality of life (QOL). Thus, the aim of this study was to evaluate the incidence of DIGH using spontaneous reporting system (SRS) databases. METHODS: We analyzed reports of DIGH from SRS databases and calculated the reporting odds ratios (RORs) of suspected drugs (immunosuppressants, calcium channel blockers, and anticonvulsants)...

PURPOSE OF REVIEW: The aim of this paper is to evaluate recent literature on valproic acid (VPA) in women and girls of childbearing age and to emphasize new findings. RECENT FINDINGS: Recent research confirms VPAs teratogenicity and risk of hormone disruption. VPA exposure in utero increases the risk for a variety of major congenital malformations (MCMs), reduced IQ and behavioral problems. In girls and women, VPA increases the risk of hormone abnormalities, obesity, and polycystic ovarian syndrome (PCOS)...

BACKGROUND: Obesity is known as an epidemic worldwide because of consumption of westernized high-fat diets and one of the major risk factors of hypertension. Histone deacetylases (HDACs) control gene expression by regulating histone/non-histone protein deacetylation. HDAC inhibitors exert anti-cancer and anti-inflammatory effects and play a protective role in cardiovascular diseases. In the present study, we tested the effect of an FDA-approved pan-HDAC inhibitor valproic acid (VPA) on high-fat diet (HFD)-induced hypertension in mice...

Depression is generally treated with antidepressants, but may often need antipsychotics and mood stabilizers. We discuss the updated data regarding the safety in pregnancy of antidepressants and antipsychotics, except selective serotonin reuptake inhibitors, and their possible impact on the long-term development of the offspring. Several earlier studies demonstrated a slight increase in the rate of major anomalies following maternal tricyclic antidepressant treatment, but most current literature shows their relative safety in pregnancy...

Neurodevelopmental disorders are congenital impairments, impeding the growth and development of the central nervous system. These disorders include autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder in Diagnostic and Statistical Manual of Mental Disorders-5. ASD is caused by a gene defect and chromosomal duplication. Despite numerous reports on ASD, the pathogenic mechanisms are not clear. The optimal methods to prevent ASD and to treat it are also not clear. Other studies have reported that endoplasmic reticulum (ER) stress contributes to the pathogenesis of neurodegenerative diseases...

Cancer stem cells (CSCs) are capable of reconstructing cancer tissues, are involved in both recurrence and metastasis, and contribute to therapeutic resistance. Therefore, elucidating the molecular mechanism in CSCs is important to successfully treat unresectable cancers. Previously we observed that colon cancer stem-like cells can be induced from human colon cancer cell lines by retrovirally introducing OCT3/4, SOX2 and KLF4, and we have designated such cells as induced cancer stem cells (iCSCs). In the current study, we used iCSCs to evaluate the molecular mechanism of colon CSCs and developed new methods to control them...

The chemotherapy drug, 5-fluorouracil (5-FU), has been reported to cause cognitive impairments in cancer patients. The drug also reduces cell proliferation and survival in the brain. Asiatic acid (AA) is a triterpene compound found in Centella asiatica that can protect against reduction of neurogenesis in the hippocampus and memory deficits induced by valproic acid (VPA). In the present study, we investigated the preventive effects of AA on the deficits in spatial working memory and cell proliferation and survival caused by 5-FU chemotherapy in a rat model...

BACKGROUND: Valproic acid (VPA) is a widely prescribed medicine, and acute toxicity is possible. As such, it should be included in any nontargeted urine drug screening method. In many published liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS/MS) methods, VPA is usually measured using a pseudo-multiple reaction monitoring (MRM) transition. We investigate a simple ultra-high-performance liquid chromatography-quadrupole time-of-flight (QTof) approach to detect the presence of VPA with more confidence...

BACKGROUND: Valproic acid (VPA) is widely used as an antiepileptic drug in children, and it is usually co-administered with other antiepileptic drugs. Due to its narrow therapeutic range and large variations in pharmacokinetic/pharmacodynamic behavior in different individuals, therapeutic drug monitoring (TDM) of the trough total VPA concentration is commonly used to guide dosing. However, as only the free fraction of VPA that exerts pharmacological and toxic effects, it may be more meaningful to determine the unbound VPA concentration in plasma...

BACKGROUND: We have previously shown that treatment with valproic acid (VPA) decreases brain lesion size in swine models of traumatic brain injury (TBI) and controlled hemorrhage. To translate this treatment into clinical practice, validation of drug efficacy and evaluation of pharmacologic properties in clinically realistic models of injury are necessary. In this study, we evaluate neurologic outcomes and perform pharmacokinetic analysis of a single dose of VPA in swine subjected to TBI, hemorrhagic shock, and visceral hemorrhage...

BACKGROUND: Our previous study has detected a stem cell deficiency in the renal medulla in Dahl salt-sensitive (S) rats. This study determined whether infusion of valproic acid (VA), an agent known to stimulate the stem cell function, attenuated salt-sensitive hypertension in Dahl S rats. METHODS: Uninephrectomized Dahl S rats were infused with vehicle or VA (50mg/kg/d) into the renal medulla and fed with a low (LS) or high salt diet (HS). Stem cell marker and number were analyzed by immunohistochemistry, Real-time RT-PCR and Western blot...

BACKGROUND: Administration of valproic acid (VPA) is complicated with approximately 0.9% of patients developing hyperammonemia, but the pathogenesis of this adverse effect remains to be clarified. The aim of the present study was to search for mechanisms associated with VPA-induced hyperammonemia in the light of changes in serum amino acids concentrations associated with the urea cycle of schizophrenic patients. METHOD: Blood samples (10 mL) were obtained from 37 schizophrenic patients receiving VPA for the prevention of violent behaviors in the morning after overnight fast...

The striatum comprises two neurochemical compartments: striosomes and the matrix. Striosomal and matrix compartments receive inputs from limbic-related and sensorimotor cortices, respectively. Here, we investigate the impact on the corticostriosomal pathway in the valproic acid (VPA)-induced autism spectrum disorder mouse model. VPA administration during the neurogenesis time windows of striosomes, but not the matrix, resulted in aberrant compartmentation [i.e., maternal VPA injections at embryonic day (E)12...
