Valerenic Acid Potentiates and Inhibits GABAA Receptors: Molecular Mechanism and Subunit Specificity

Hering a,* a Department of Pharmacology and Toxicology, University of Vienna, Althanstrasse 14, A-1090 Vienna, Austria b Department of Pharmacognosy, University of Vienna, Althanstrasse 14, A-1090 Vienna, Austria Received 8 December 2006; received in revised form 11 April 2007; accepted 30 April 2007 Abstract Valerian is a commonly used herbal medicinal product for the treatment of anxiety and insomnia. Here we report the stimulation of chloride currents through GABAA receptors (IGABA) by valerenic acid (VA), a constituent of Valerian. To analyse the molecular basis of VA action, we expressed GABAA receptors with 13 different subunit compositions in Xenopus oocytes and measured IGABA using the two-microelectrode voltage-clamp technique. We report a subtype-dependent stimulation of IGABA by VA. Only channels incorporating b2 or b3 subunits were stimulated by VA. Replacing b2/3 by b1 drastically reduced the sensitivity of the resulting GABAA channels. The stimulatory effect of VA on a1b2 receptors was substantially reduced by the point mutation b2N265S (known to inhibit loreclezole action). Mutating the corresponding residue of b1 (b1S290N) induced VA sensitivity in a1b1S290N comparable to a1b2 receptors. Modulation of IGABA was not significantly dependent on incorporation of a1, a2, a3 or a5 subunits. VA displayed a significantly lower efficiency on channels incorporating a4 subunits. IGABA modulation by VA was not g subunit dependent and not inhibited by flumazenil (1 mM). -

However, a comprehensive review of plant-based anxiolytics has been absent to date. Thus, our aim was to provide a comprehensive narrative review of plant-based medicines that have clinical and/or preclinical evidence of anxiolytic activity. We present the article in two parts. In part one, we reviewed herbal medicines for which only preclinical investigations for anxiolytic activity have been performed. In this current article (part two), we review herbal medicines for which there have been both preclinical and clinical investigations for anxiolytic activity. -

Zebrafish Behavioural Profiling Identifies GABA and Serotonin
ARTICLE https://doi.org/10.1038/s41467-019-11936-w OPEN Zebrafish behavioural profiling identifies GABA and serotonin receptor ligands related to sedation and paradoxical excitation Matthew N. McCarroll1,11, Leo Gendelev1,11, Reid Kinser1, Jack Taylor 1, Giancarlo Bruni 2,3, Douglas Myers-Turnbull 1, Cole Helsell1, Amanda Carbajal4, Capria Rinaldi1, Hye Jin Kang5, Jung Ho Gong6, Jason K. Sello6, Susumu Tomita7, Randall T. Peterson2,10, Michael J. Keiser 1,8 & David Kokel1,9 1234567890():,; Anesthetics are generally associated with sedation, but some anesthetics can also increase brain and motor activity—a phenomenon known as paradoxical excitation. Previous studies have identified GABAA receptors as the primary targets of most anesthetic drugs, but how these compounds produce paradoxical excitation is poorly understood. To identify and understand such compounds, we applied a behavior-based drug profiling approach. Here, we show that a subset of central nervous system depressants cause paradoxical excitation in zebrafish. Using this behavior as a readout, we screened thousands of compounds and identified dozens of hits that caused paradoxical excitation. Many hit compounds modulated human GABAA receptors, while others appeared to modulate different neuronal targets, including the human serotonin-6 receptor. Ligands at these receptors generally decreased neuronal activity, but paradoxically increased activity in the caudal hindbrain. Together, these studies identify ligands, targets, and neurons affecting sedation and paradoxical excitation in vivo in zebrafish. 1 Institute for Neurodegenerative Diseases, University of California, San Francisco, CA 94143, USA. 2 Cardiovascular Research Center and Division of Cardiology, Department of Medicine, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA. -

Updating the Biological Interest of Valeriana Officinalis
ARTICLES Mediterranean Botany ISSNe 2603-9109 https://dx.doi.org/10.5209/mbot.70280 Updating the biological interest of Valeriana officinalis Marta Sánchez1 , Elena González Burgos1 , Irene Iglesias1 & M. Pilar Gómez-Serranillos1 Received: 23 June 2020 / Accepted: 5 August 2020 / Published online: 11 January 2021 Abstract. Valeriana officinalis L. (Caprifoliaceae) has been traditionally used to treat mild nervous tension and sleep problems. The basis of these activities are mainly attributed to valerenic acid through the modulation of the GABA receptor. Moreover, V. officinalis is claimed to have other biological activities such as cardiovascular benefits, anticancer, antimicrobial, and spasmolytic. The current review aims to update the biological and pharmacological studies (in vitro, in vivo, and clinical trials) of V. officinalis and its major secondary metabolites to guide future research. Databases PubMed, Science Direct, and Scopus were used for literature search, including original papers written in English and published between 2014 and 2020. There have been identified 33 articles that met the inclusion criteria. Most of these works were performed withV. officinalis extracts, and only a few papers (in vitro and in vivo studies) evaluated the activity of isolated compounds (valerenic acid and volvalerenal acid K). In vitro studies focused on studying antioxidant and neuroprotective activity. In vivo studies and clinical trials mainly investigated the nervous system activity (anticonvulsant activity, antidepressant, cognitive problems, anxiety, and sleep disorders). Just a few studies were focused on other different activities, highlight effects on symptoms of premenstrual and postmenopausal syndromes. Valeriana officinaliscontinues to be one of the medicinal plants most used by today’s society for its therapeutic properties and whose biological and pharmacological activities continue to arouse great scientific interest, as evidenced in recent publications. -

Equestrian Canada Drug Classification Scheme
Equestrian Canada Drug Classification Scheme This Classification Scheme does not constitute a Prohibited List of banned substances not allowed in horses. Rather, it is designed to allow a hearing panel, after an equine medication violation has been determined, to determine the most appropriate sanction. The drugs, medications and types of substances listed under each Class are not exhaustive. The list in each Class provides examples of drugs, medications and types of substances with similar effects on a horse or that are considered equivalently serious when detected in a horse participating in an EC sanctioned competition. Sanctions will be imposed on a Class by Class basis. Class 1: - Substances which have no place in performing horses. Many of these compounds do not have legitimate medical uses in horses, and the remaining compounds would only be used for severely debilitated animals. Abuse of these compounds is of serious ethical (and many cases, legal) concern. - Most of these compounds are included in Schedules 1 and 3 of the Canadian Controlled Drugs and Substances Act (CDSA) - Examples of Class 1 drugs: o Opioids such as fentanyl, morpine, heroin and codeine o Cocaine o Amphetamine and its derivatives listed in Schedule 3 of the CDSA o Methylphenidate (Ritalin) o Methaqualone Class 2: - These compounds are not appropriate for use around the time of performance. Inappropriate use may alter the horse’s behaviour and ability to perform; medical use of these compounds indicates health status incompatible with athletic competition. -

Root Culture of Valeriana Officinalis by Elicitation

The plant produces only small amounts of this metabolite naturally. So, induction of hairy roots as well as elicitation can be useful to increase its commercial production. In this study, Wild-type strain ‘A13’ of Agrobacterium rhizogenes was used to induce hairy roots in valerian. The influence of three different elicitors including Fusarium graminearum extract (FE), methyl jasmonate (MJ) and salicylic acid (SA) on VA production in the selected hairy root line ‘LeVa-C4’ was also investigated. The 23-day-old cultures were treated with different concentrations of the elicitors at exposure time of 3 and 7 days. FE (1%) and MJ (100 µM L-1) highly promoted VA production at 7 days after elicitation, to a level of 12.31- and 6-fold higher than that of non-elicited controls, respectively, and FE did not exert any negative effects on biomass yield of hairy root. -
