Piracetam (2-oxo-1-pyrrolidine acetamide) is a popular cognitive enhancer, which has recently been detected in waste and drinking water. Nootropic drugs are designed to affect human metabolism and act on the nervous system, but their environmental effects have yet to be the subject of detailed studies. In this report, we present the efficient biodegradation of the cognitive enhancer, piracetam. Two bacterial strains capable of using this compound as the sole carbon source were isolated and later identified as Ochrobactrum anthropi strain MW6 and Ochrobactrum intermedium strain MW7...

Developing brain ischemia due to cerebral vascularization leads to disruption of brain metabolism. Chronic cerebral hypoperfusion leads to irreversible brain damage and plays an important role in the development of some types of dementia. Early use of antioxidants such as ethyl ether apovincamine acid (vinpocetine) and 2-ethyl-6-methyl-3-hydroxypyridine-succinate in the treatment of this pathology is seen as a real pathogenetically based method of correction of cerebral metabolism with cerebral vascular disorders, demonstrating the increase in cerebral blood flow and also neuroprotective effects...

Neurodegenerative diseases and inflammation are always linked to each other; therefore the elaboration of new chemical compounds, which interact with pharmacological targets involved into these two processes, can become one of ways of correction of these types of human CNS pathology. In the field of this problem the anti-inflammatory activity of ten 3-amino derivatives of quinolizidine alkaloid (-)-cytisine (the data about nootropic activity of these compounds are outlined by us previously) was studied by using in vivo, in vitro and in silico approaches...

Alzheimer's disease (AD) is a progressive neurodegenerative disease of the elderly. The rapid increase in its incidence has necessitated development of newer drugs. Ayurvedic herbal medications are increasingly researched due to their biosafety profile and usefulness in cognitive impairment. In this article, we critically reviewed one such Medhya Rasayana (nootropic drug) Brahmi-derived from extract of Bacopa monnieri (EBm). Studies have shown that EBm promotes free radical scavenger mechanisms and protects cells in prefrontal cortex, hippocampus, and striatum against cytotoxicity and DNA damage implicated in AD...

BACKGROUND: The current therapy of neuropathic pain is inadequate and is limited by the extent of pain relief and the occurrence of dose dependant side effects. Insufficient control of pain with conventional medications prompts the use of complementary and alternative medicine therapies by patients with neuropathic pain. This study therefore investigated a standardized methanolic extract of Bacopa monnieri, a widely reputed nootropic plant, for prospective antinociceptive effect in the chronic constriction injury (CCI) model of neuropathic pain...

Choline alfoscerate (α-GPC) and Cytidine 5'-diphosphocholine (CDP-Choline) are both acetylcholine precursors and are considered to act as pro-cholinergic nootropic agents. Acetylcholine precursors have also recently found frequent use in the neurology clinic. Stroke and many types of dementia have been shown to respond favorably after treatment with these agents, not only in terms of cognitive dysfunction but also behavioral and psychological symptoms. The primary mechanisms of Acetylcholine precursors are the following: 1) Acetylcholine precursors themselves are used in the biosynthesis of acetylcholine and 2) byproducts like glycerophosphate have protective functions for neuronal phospholipids...

Alcohol addiction is a worldwide problem. It has mainly two components: dependence and withdrawal. Characteristic properties of most anti-addictive compounds include anti-anxiety, anticonvulsant, antidepressant, and nootropic actions. Shankhpushpi (Convolvulus pluricaulis. Convolvulaceae), known ethnopharmacologically as brain tonic, possess all the properties mentioned above. Here, we screen shankhpushpi for possible anti-addictive potential. Effect of shankhpushpi churna was measured on ethanol withdrawal anxiety using elevated plus maze...

Tardive dyskinesia (TD) is associated with the use of antipsychotic drugs such as D2 antagonist haloperidol (HP). The chronic use of HP is involved in the causation of free radicals and/or oxidative stress. In view of the nootropic, anti-anxiety, anti-inflammatory-like effects of rice bran oil (RBO) in a variety of investigations, we assessed the protective properties of RBO on HP-induced TD and neurochemical alteration. Rats treated with HP orally at a dose of 0.2 mg/kg/day for a period of 5 weeks developed VCMs which increased progressively as the treatment continued for 5 weeks...

Acute kidney injury (AKI) represents a complex clinical condition associated with significant morbidity and mortality. Approximately, 19-33% AKI episodes in hospitalized patients are related to drug-induced nephrotoxicity. Although, considered safe, non-steroidal anti-inflammatory drugs such as diclofenac have received special attention in the past years due to the potential risk of renal damage. Vinpocetine is a nootropic drug known to have anti-inflammatory properties. In this study, we investigated the effect and mechanisms of vinpocetine in a model of diclofenac-induced AKI...

ACTH, a member of the melanocortin family of peptides, is often used in the treatment of the developmental epileptic encephalopathy spectrum disorders including, Ohtahara, West, Lennox Gastaut and Landau-Kleffner Syndromes and electrical status epilepticus of sleep. In these disorders, although ACTH is often successful in controlling the seizures and/or inter-ictal EEG abnormalities, it is unknown whether ACTH possesses other beneficial effects independent of seizure control. We tested whether ACTH can ameliorate the intrinsic impairment of hippocampal-based learning and memory in epileptic Kcna1-null (KO) mice...

The piperazine ring of the potent nootropic drug DM235 has been decorated with H-bond donor and acceptor groups (CH2OH, CH2OMe, CH2OCOMe, COOEt); the aim was to insert new functional groups, suitable for further chemical manipulation. The influence of these modifications on nootropic activity was assessed by means of the mouse passive avoidance test; some of the newly synthesized molecules (alcohol 7b, acetate 8b and ester 10d) showed interesting in vivo potency. This makes it possible to use these functional groups for adding other residues, in order to increase molecular diversity, or for anchoring a biotin group, to obtain compounds useful to capture the biological target...

BACKGROUND: N-benzylpiperazine (BZP) belongs to a class of piperazine derivatives (PZDs) that have emerged as recreational drugs. These compounds increase the release of dopamine and serotonin. BZP mimics the psychoactive effects of 3,4-methylenedioxymethylamphetamine. BZP is metabolized to N-benzylethylenediamine (BEDA) and benzylamine. The compound N,N'-dibenzylpiperazine (DBZP) is obtained as a byproduct during the synthesis of BZP. Some PZDs have shown effects on memory; however, there are no previous reports on the activity of BZP, BEDA, and DBZP on memory or on a description of their neuropharmacological profile...

BACKGROUND: Diabetes mellitus (DM) of juvenile onset affects both the peripheral and central nervous systems (CNS). However, central effects are less documented and studied than peripheral deficits. Currently, the only feasible treatment available for type 1 DM (T1DM) is insulin which has its own limitations. Hence, an alternative therapy, especially a newer herbal formulation is very much the need of the time. The present study aimed to determine the effects of the alcoholic extracts of roots of the Salacia reticulata W...
