Polymeric and polymer-ligated spirobicyclic zwitterionic Janovsky complexes

A novel approach to the synthesis of spirobicyclic Janovsky complexes is described. The complexes were prepared on silica and polystyrene polymeric supports as well as on a solution-borne poly(carbodiimide) polymer with 100% atom economy. A carbon-centered intramolecular de-aromatizing nucleophilic aromatic substitution ipso-cyclization mechanism describes the synthesis of these spirobicyclics. The molecules were characterized by solution and solid-state 1H and 13C NMR, IR, and MS. Crown Copyright

Inter-laboratory assessment of a harmonized zebrafish developmental toxicology assay – Progress report on phase I

This report provides a progress update of a consortium effort to develop a harmonized zebrafish developmental toxicity assay. Twenty non-proprietary compounds (10 animal teratogens and 10 animal non-teratogens) were evaluated blinded in 4 laboratories. Zebrafish embryos from pond-derived and cultivated strain wild types were exposed to the test compounds for 5 days and subsequently evaluated for lethality and morphological changes. Each of the testing laboratories achieved similar overall concordance to the animal data (60-70%). Subsequent optimization procedures to improve the overall concordance focused on compound formulation and test concentration adjustments, chorion permeation and number of replicates. These optimized procedures were integrated into a revised protocol and all compounds were retested in one lab using embryos from pond-derived zebrafish and achieved 85% total concordance. To further assess assay performance, a study of additional compounds is currently in progress at two laboratories using embryos from pond-derived and cultivated-strain wild type zebrafish.

Fenfluramine hydrochloride for the treatment of Dravet syndrome

Introduction: Fenfluramine (3?trifluoromethyl?N?ethylamphetamine), a former anorectic agent, has been successfully repurposed for Dravet syndrome (DS). Area covered: A systematic review of data on fenfluramine in the treatment of patients with DS has been conducted, with 11 published papers on the use of fenfluramine for DS (six clinical trials, of which two were randomized controlled trials (RCTs), and five preclinical studies). Following clinical observations suggesting the efficacy of fenfluramine, the effect on convulsive seizures has been confirmed by two RCTs. The first RCT demonstrated the efficacy of the two tested doses of 0.2 mg/kg/day and 0.7 mg/kg/day, while the second RCT showed the efficacy of 0.4 mg/kg/day fenfluramine in patients with DS treated with stiripentol. Expert opinion: Preclinical studies provide insights into the mechanisms of action of fenfluramine. There are still no large real-life studies. Fenfluramine is under investigation for the treatment of other epilepsy syndromes.

Acid-Base Basics

Summary: Although students initially learn of ionic buffering in basic chemistry, buffering and acid-base transport in biology often is relegated to specialized classes, discussions, or situations. That said, for physiology, nephrology, pulmonology, and anesthesiology, these basic principles often are critically important for mechanistic understanding, medical treatments, and assessing therapy effectiveness. This short introductory perspective focuses on basic chemistry and transport of buffers and acid-base equivalents, provides an outline of basic science acid-base concepts, tools used to monitor intracellular pH, model cellular responses to pH buffer changes, and the more recent development and use of genetically encoded pH-indicators. Examples of newer genetically encoded pH-indicators (pHerry and pHire) are provided, and their use for in vitro, ex vivo, and in vivo experiments are described. The continued use and development of these basic tools provide increasing opportunities for both basic and potentially clinical investigations.

The novel antiepileptic drug levetiracetam (ucb L059) appears to act via a specific binding site in CNS membranes

Levetiracetam ((S)-alpha-ethyl-2-oxo-pyrrolidine acetamide, ucb L059) is a novel potential antiepileptic agent presently in clinical development with unknown mechanism of action. The finding that its anticonvulsant activity is highly stereoselective (Gower et al., 1992) led us to investigate the presence of specific binding sites for [3H]levetiracetam in rat central nervous system (CNS). Binding assays, performed on crude membranes, revealed the existence of a reversible, saturable and stereoselective specific binding site. Results obtained in hippocampal membranes suggest that [3H]levetiracetam labels a single class of binding sites (nH=0.92+/-0.06) with modest affinity (Kd=780+/-115 nM) and with a high binding capacity (Bmax=9.1+/-1.2 pmol/mg protein). Similar Kd and Bmax values were obtained in other brain regions (cortex, cerebellum and striatum). ucb L060, the (R) enantiomer of levetiracetam, displayed about 1000 times less affinity for these sites. The binding of [3H]levetiracetam is confined to the synaptic plasma membranes in the central nervous system since no specific binding was observed in a range of peripheral tissues including heart, kidneys, spleen, pancreas, adrenals, lungs and liver. The commonly used antiepileptic drugs carbamazepine, phenytoin, valproate, phenobarbital and clonazepam, as well as the convulsant agent t-butylbicyclophosphorothionate (TBPS), picrotoxin and bicuculline did not displace [3H]levetiracetam binding. However, ethosuximide (pKi=3.5+/-0.1), pentobarbital (pKi=3.8+/-0.1), pentylenetetrazole (pKi=4.1+/-0.1) and bemegride (pKi=5.0+/-0.1) competed with [3H]levetiracetam with pKi values comparable to active drug concentrations observed in vivo. Structurally related compounds, including piracetam and aniracetam, also displaced [3H]levetiracetam binding. (S) Stereoisomer homologues of levetiracetam demonstrated a rank order of affinity for [3H]levetiracetam binding in correlation with their anticonvulsant activity in the audiogenic mouse test (r2=0.84, n=12, P<0.0001). These results support a possible role of this binding site in the anticonvulsant activity of levetiracetam and substantiate the singular pharmacological profile of this compound. This site remains however to be further characterised. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 695-53-4, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 695-53-4, in my other articles.
