Tetrodotoxin
Niharika Mandal et al. / Journal of Pharmacy Research 2012,5(7),3567-3570 Review Article Available online through ISSN: 0974-6943 http://jprsolutions.info Tetrodotoxin: An intriguing molecule Niharika Mandal*, Samanta Sekhar Khora, Kanagaraj Mohanapriya, and Soumya Jal School of Biosciences and Technology, VIT University, Vellore-632013 Tamil Nadu, India Received on:07-04-2012; Revised on: 12-05-2012; Accepted on:16-06-2012 ABSTRACT Tetrodotoxin (TTX) is one of the most potent neurotoxin of biological origin. It was first isolated from puffer fish and it has been discovered in various arrays of organism since then. Its origin is still unclear though some reports indicate towards microbial origin. TTX selectively blocks the sodium channel, inhibiting action potential thereby, leading to respiratory paralysis. TTX toxicity is mainly caused due to consumption of puffer fish. No Known antidote for TTX exists. Treatment is symptomatic. The present review is therefore, an effort to give an idea about the distribution, origin, structure, pharmacol- ogy, toxicity, symptoms, treatment, resistance and application of TTX. Key words: Tetrodotoxin, Neurotoxin, Puffer fish. INTRODUCTION One of the most intriguing biotoxins isolated and described in the twentieth cantly more toxic than TTX.

Interestingly, there is also some evidence for a bacterial bio- ing with membrane proteins and ion channels mostly resulting in paralysis. -
Illegal Drugs in Canada: Refocusing Canada’S Drug Strategy
Illegal Drugs in Canada: Refocusing Canada’s Drug Strategy Major Research Paper By: Nicole Barrafato Ottawa University 1 May 2013 Introduction “Billions of dollars have gone into the anti-drug war and it has brought only huge criminal organizations. When you have poured in money for a century surely it is time for you to decide it is not working.” Dr E.K. Rodrigo, former Drug Tsar of Sri Lanka 2005 In the last decade international attitudes towards the prohibition of illegal drugs have undergone rapid change. For over half a century governments around the world have been fighting a declared “war on drugs.” Within the last two decades, however, most have conceded that this crusade has been an unmitigated failure. Even though most of the international community has acknowledged this failure, it has been slow to re-conceptualize how it views illegal drugs and explore alternative policies. Part I of this paper demonstrates that the rapid globalization of the past three decades has had a significant impact on the scope, speed and scale of deviant globalization, where illicit industries operate in the shadows of the legitimate global economy. It was also around this time that the American-led “war on drugs” was launched, which essentially shaped the international drug control regime. Part II addresses the failures of the current prohibition regime and outlines alternative policy approaches that could instead be taken to address the problem of illicit drugs. In addition, case studies on countries that have been at the forefront of innovative drug policies, namely the Netherlands, Portugal and Australia, will also be examined. -
The Seed of Industrial Hemp (Cannabis Sativa L.): Nutritional Quality and Potential Functionality for Human Health and Nutrition
nutrients Review The Seed of Industrial Hemp (Cannabis sativa L.): Nutritional Quality and Potential Functionality for Human Health and Nutrition Barbara Farinon * , Romina Molinari , Lara Costantini and Nicolò Merendino * Department of Ecological and Biological Sciences (DEB), Tuscia University, Largo dell’Università snc, 01100 Viterbo, Italy; [email protected] (R.M.); [email protected] (L.C.) * Correspondence: [email protected] (B.F.); [email protected] (N.M.) Received: 25 May 2020; Accepted: 23 June 2020; Published: 29 June 2020 Abstract: Hempseeds, the edible fruits of the Cannabis sativa L. plant, were initially considered a by-product of the hemp technical fibre industry. Nowadays, following the restorationing of the cultivation of C. sativa L. plants containing an amount of delta-9-tetrahydrocannabinol (THC) <0.3% or 0.2% (industrial hemp) there is a growing interest for the hempseeds production due to their high nutritional value and functional features. The goal of this review is to examine the scientific literature concerning the nutritional and functional properties of hempseeds. Furthermore, we revised the scientific literature regarding the potential use of hempseeds and their derivatives as a dietary supplement for the prevention and treatment of inflammatory and chronic-degenerative diseases on animal models and humans too. In the first part of the work, we provide information regarding the genetic, biochemical, and legislative aspects of this plant that are, in our opinion essential to understand the difference between “industrial” and “drug-type” hemp. In the final part of the review, the employment of hempseeds by the food industry as livestock feed supplement and as ingredient to enrich or fortify daily foods has also revised. -

A Polyketoacyl-Coa Thiolase-Dependent Pathway for the Synthesis of Polyketide Backbones
ARTICLES https://doi.org/10.1038/s41929-020-0471-8 A polyketoacyl-CoA thiolase-dependent pathway for the synthesis of polyketide backbones Zaigao Tan1,3, James M. Clomburg1,2, Seokjung Cheong1, Shuai Qian1 and Ramon Gonzalez 1,2 ✉ Polyketides found in nature originate from backbones synthesized through iterative decarboxylative Claisen condensations catalysed by polyketide synthases (PKSs). However, PKSs suffer from complicated architecture, energy inefficiencies, complex regulation, and competition with essential metabolic pathways for extender unit malonyl-CoA, all combining to limit the flux of polyketide biosynthesis. Here we show that certain thiolases, which we term polyketoacyl-CoA thiolases (PKTs), catalyse polyketide backbone formation via iterative non-decarboxylative Claisen condensations, hence offering a synthetic and effi- cient alternative to PKSs. We show that PKTs can synthesize polyketide backbones for representative lactone, alkylresorcinolic acid, alkylresorcinol, hydroxybenzoic acid and alkylphenol polyketide families, and elucidate the basic catalytic mechanism and structural features enabling this previously unknown activity. PKT-catalysed reactions offer a route to polyketide formation that leverages the simple architecture of thiolases to achieve higher ATP efficiencies and reduced competition with essential metabolic pathways, all of which circumvent intrinsic inefficiencies of PKSs for polyketide product synthesis. olyketides represent a large class of secondary metabolites that Here we show that enzymes other -

The central hypothesis to be tested is that the time-and drug-dependent KOR-mediated regulation of ERK1/2 MAP kinase activity occurs via distinct molecular mechanisms, which in turn may determine the modulation (suppression or potentiation) by KOR effects on cocaine conditioned place preference (CPP). Three studies were performed to test this hypothesis. Study 1 examined the effects of U50,488 and salvinorin A on cocaine reward. In these studies, mice were treated with equianalgesic doses of agonist from 15 to 360 min prior to daily saline or cocaine place conditioning. At time points corresponding with peak biological activity, both agonists produced saline-conditioned place aversion and suppressed cocaine-CPP, effects blocked by the KOR antagonist nor-BNI. However, when mice were place conditioned with cocaine 90 min after agonist pretreatment, U50,488-pretreated mice demonstrated a 2.5-fold potentiation of cocaine-CPP, whereas salvinorin A-pretreated mice demonstrated normal cocaine-CPP responses. -

Design & Synthesis of Polycyclic Amine Derivatives for Sigma Receptor Activity
UNIVERSITY OF THE WESTERN CAPE Design & Synthesis of Polycyclic Amine derivatives for Sigma Receptor Activity Natasha Strydom February 2013 Supervisor: Prof. S.F. Malan Co-Supervisor: Dr. J. Joubert A thesis submitted in partial fulfilment of the requirements for the degree of Magister Scientiae in the Department of Natural Sciences, University of the Western Cape. KEYWORDS Polycyclic amine Pentacycloundecane Amantadine Heterocyclic amines Sigma receptor Neurodegeneration Drug addiction Blood brain permeability Drug Design Ligand based Structure activity relationship i ABSTRACT New therapeutic strategies are needed for a diverse array of poorly understood neurological impairments. These include neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, and the psychiatric disorders such as depression, anxiety and drug dependence. Popular neuropharmacotherapies have focused on dopamine (DA), serotonin (5HT), γ-aminobutric acid (GABA) and glutamate systems (Jupp & Lawrence, 2010). However recent research points to the sigma receptor (σR) as a possible neuromodulatory system. Due to its multi-receptor action, the σR can trigger several significant biological pathways. This indicates its ideal potential as a drug target to effectively minimise drug dosage and potential side effects. Currently there are a limited number of σR ligands available and few possess the selectivity to significantly show σR’s role in neurological processes. Polycyclic amines have shown notable sigma activity and provide an advantageous scaffold for drug design that can improve pharmacodynamic and pharmacokinetic properties (Banister et al., 2010; Geldenhuys et al., 2005). Aryl-heterocycle amine groups were also shown to improve σR activity (Piergentili et al., 2009). A series of pentacycloundecane compounds were synthesised which aimed at evaluating the inclusion of a amine containing aryl group in the design compared to previous pentacycloundecane structures containing only two lipophilic regions.
