Sulthiame add-on therapy for epilepsy

Background This is an updated version of the Cochrane Review previously published in the Cochrane Database of Systematic Reviews 2015, Issue 10. Epilepsy is a common neurological condition, characterised by recurrent seizures. Most people respond to conventional antiepileptic drugs, however, around 30% will continue to experience seizures, despite treatment with multiple antiepileptic drugs. Sulthiame, also known as sultiame, is a widely used antiepileptic drug in Europe and Israel. We present a summary of the evidence for the use of sulthiame as add-on therapy in epilepsy. Objectives To assess the efficacy and tolerability of sulthiame as add-on therapy for people with epilepsy of any aetiology compared with placebo or another antiepileptic drug. Search methods For the latest update, we searched the Cochrane Register of Studies (CRS Web), which includes the Cochrane Epilepsy Group’s Specialized Register and CENTRAL (17 January 2019), MEDLINE Ovid (1946 to January 16, 2019), ClinicalTrials.gov and the WHO ICTRP Search Portal (17 January 2019). We imposed no language restrictions. We contacted the manufacturers of sulthiame, and researchers in the field to seek any ongoing or unpublished studies. Selection criteria Randomised controlled trials of add-on sulthiame, with any level of blinding (single, double or unblinded) in people of any age, with epilepsy of any aetiology. Data collection and analysis Two review authors independently selected trials for inclusion, and extracted relevant data. We assessed these outcomes: (1) 50% or greater reduction in seizure frequency between baseline and end of follow-up; (2) complete cessation of seizures during follow-up; (3) mean seizure frequency; (4) time-to-treatment withdrawal; (5) adverse effects; and (6) quality of life. We used intention-to-treat for primary analyses. We presented results as risk ratios (RR) with 95% confidence intervals (CIs). However, due to the paucity of trials, we mainly conducted a narrative analysis. Main results We included one placebo-controlled trial that recruited 37 infants with newly diagnosed West syndrome. This trial was funded by DESITIN Pharma, Germany. During the study, sulthiame was given as an add-on therapy to pyridoxine. No data were reported for the outcomes: 50% or greater reduction in seizure frequency between baseline and end of follow-up; mean seizure frequency; or quality of life. For complete cessation of seizures during a nine-day follow-up period for add-on sulthiame versus placebo, the RR was 11.14 (95% CI 0.67 to 184.47; very low-certainty evidence), however, this difference was not shown to be statistically significant (P = 0.09). The number of infants experiencing one or more adverse events was not significantly different between the two treatment groups (RR 0.85, 95% CI 0.44 to 1.64; very low-certainty evidence; P = 0.63). Somnolence was more prevalent amongst infants randomised to add-on sulthiame compared to placebo, but again, the difference was not statistically significant (RR 3.40, 95% CI 0.42 to 27.59; very low-certainty evidence; P = 0.25). We were unable to conduct meaningful analysis of time-to-treatment withdrawal and adverse effects due to incomplete data. Authors’ conclusions Sulthiame may lead to a cessation of seizures when used as an add-on therapy to pyridoxine in infants with West syndrome, however, we are very uncertain about the reliability of this finding. The included study was small and had a significant risk of bias, largely due to the lack of details regarding blinding and the incomplete reporting of outcomes. Both issues negatively impacted the certainty of the evidence. No conclusions can be drawn about the occurrence of adverse effects, change in quality of life, or mean reduction in seizure frequency. No evidence exists for the use of sulthiame as an add-on therapy in people with epilepsy outside West syndrome. Large, multi-centre randomised controlled trials are needed to inform clinical practice, if sulthiame is to be used as an add-on therapy for epilepsy.

Selective Construction of Diverse Polycyclic Spirooxindoles via a Three-Component Reaction of Cyclic Mercapto-Substituted beta-Enamino Esters, Isatins, and Cyclic 1,3-Diketones

The three-component reaction of alkyl 2-(benzo[b][1,4]thiazin-3-ylidene)acetates, isatins, and 1,3-indanedione (1,3-cyclopentanedione) in ethanol in the presence of acetic acid conveniently afforded spiro[indeno[1,2-b]phenothiazine-6,3′-indolines] or spiro[cyclopenta[b]phenothiazine-4,3′-indolines] in good yields and with high diastereoselectivity. More interestingly, a similar three-component reaction with 4-hydroxychromen-2-one resulted in the unexpected polycyclic spiro[benzo[b]chromeno[3′,4′:5,6]-pyrano[2,3-e][1,4]thiazine-7,3′-indolines] in satisfactory yields. A plausible reaction mechanism was rationally proposed for formation of different kinds of the spiro compounds, and the stereochemistries of the various spiro compounds were clearly elucidated.

Thiazine Red(+) platelet inclusions in Cerebral Blood Vessels are first signs in an Alzheimer’s Disease mouse model

Strong evidence shows an association between cerebral vascular diseases and Alzheimer’s disease (AD). In order to study the interaction of beta-amyloid (A beta) plaques with brain vessels, we crossbred an AD mouse model (overexpressing amyloid precursor protein with the Swedish-Dutch-Iowa mutations, APP_SweDI) with mice expressing green fluorescent protein (GFP) under the flt-1/VEGFR1 promoter in vessels (GFP_FLT1). Our data show, that only very few A beta plaques were seen in 4-months old mice, focused in the mammillary body and in the lateral septal nucleus. The number of plaques markedly increased with age being most prominent in 12-months old mice. Thiazine Red was used to verify the plaques. Several Thiazine Red(+) inclusions were found in GFP(+) vessels, but only in non-perfused 4-months old mice. These inclusions were verified by Resorufin stainings possibly representing cerebral amyloid angiopathy. The inclusions were also seen in non-crossbred APP_SweDI but not in wildtype and GFP_FLT1 mice. In order to characterize these inclusions Flow Cytometry (FACS) analysis demonstrated that platelets were specifically stained by Thiazine Red(+), more pronounced when aggregated. In conclusion, our data show that Thiazine Red(+) inclusions representing aggregated platelets are a first pathological sign in AD before plaque development and may become important therapeutic targets in early AD.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 82911-69-1. The above is the message from the blog manager. Recommanded Product: N-(9-Fluorenylmethoxycarbonyloxy)succinimide.

An Approach to Polysubstituted Triazipines, Thiadiazoles and Thiazoles Based on Benzopyran Moiety Through The Utility of Versatile Hydrazonoyl Halides as In Vitro Monoamine Oxidase Inhibitors

The chromene compound 1 is used as a key intermediate for synthesis of new heterocyclic compounds, and it reacted with hydrazonoyl chlorides in presence of TEA to give the amidrazone derivatives 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, which were cyclized to the corresponding triazepines 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h on boiling with sodium ethoxide. Conversion of compound 1 to the methylthiocarbamate derivative 6 was performed through its reaction with carbon disulfide and KOH followed by treatment with methyl iodide. Compound 6 reacted with hydrazonoyl chlorides in presence of TEA to give thiadiazoles 8a, 8b, 8c, 8d, 8e, 8f, 8g. In addition, chromene 1 combined with aminodithiocarbamic acid in DMF under reflux to furnish the thiosemicarbazide derivative 9, which in turn interacted with several hydrazonoyl chlorides to give the thiazole derivatives 11a, 11b, 11c, 11d, 11e. The structures of the prepared compounds were confirmed from their spectroscopic data and elemental analysis. The synthesized compounds were tested against both monoamine oxidase (MAO)-A and MAO-B and corrected to analyses showed good inhibitory activities especially against MAO-A.

Laccase mediator system obtained from a marine spore exhibits decolorization potential in harsh environmental conditions

Laccases play a significant role in remedying dye pollutants. Most of these enzymes are originated from terrestrial fungi and bacteria, thus they are not proper to be used in the environments with neutral/alkaline pH, or they may require laborious extraction/purification steps. These limitations can be solved using marine spore laccases through high stability and easy to use application. In the current study, laccase activity of the marine spore-forming Bacillus sp. KC2 was measured according to the guaiacol and syringaldazine oxidation. Abiotic stresses like pH of 6, temperature of 37 degrees C and 0.3 mM CuSO4 (in comparison with optimal sporulation conditions: pH of 8, temperature of 20 degrees C and 0.0 mM CuSO4) enhanced laccase formation in sporal coat. Maximum activity of enzyme was observed at 50 degrees C and pH 7, which did not change in the alkaline pH and temperature range of 20-70 degrees C. Results indicated ions, inhibitors and solvent stability of the enzyme and its activity were stimulated by Co2+, Mn2+, PMSF, acetone, acetonitrile, ethanol, and methanol. The spore laccase could decolorize synthetic dyes from various chemical groups including azo (acid orange, amaranth, trypan blue, congo red, and amido black), indigo (indigo carmine), thiazine (methylene blue, and toluidine blue), and triarylmethane (malachite green) with ABTS/syringaldazine mediators after 5 h. Degradation products were not toxic against Sorghum vulgare and Artemia sauna model organisms. The enzyme mediator system showed high potentials for dye bioremediation over a wide range of harsh conditions.

Lipophilicity estimation of anti-proliferative and anti-inflammatory 6-substituted 9-fluoroquino[3,2-b]benzo[1,4]thiazines

The lipophilicity parameters (logP(calcd), R-M0 and logP(TLC)) of 17 new anti-proliferative and anti-inflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines were determined theoretically using computational methods and experimentally by reversed-phase thin-layer chromatography. The experimental parameter R-M0 was determined on the RP-18 silica plates with acetone-aqueous TRIS buffer as mobile phase. The obtained parameter R-M0 was further transformed into parameter logP(TLC) by use of the calibration curve. The theoretical logP(calcd) values differed depending on the substituents and nature of calculating programs. Fluoroquinobenzothiazines turned out to be rather middling or highly lipophilic compounds. The parameter R-M0 and specific hydrophobic surface area b were meaningly intercorrelated showing congeneric two classes of quinobenzothiazines. The calculated logP(calcd) and experimental logP(TLC) values were compared and intercorrelated to show different prediction power of the computational programs. The lipophilicity was correlated with molecular descriptors (molar mass, molar volume, and molar refractivity), biomolecular descriptors (HIA, PB, MDCK, Caco-2, and BBB) and in vitro tested biological activities (tumor necrosis factor alpha inhibition and antiproliferative activity).

Discovery of an Extremely Potent Thiazine-Based beta-Secretase Inhibitor with Reduced Cardiovascular and Liver Toxicity at a Low Projected Human Dose

Genetic evidence points to deposition of amyloid-beta (A beta) as a causal factor for Alzheimer’s disease. A beta generation is initiated when beta-secretase (BACE1) cleaves the amyloid precursor protein. Starting with an oxazine lead 1, we describe the discovery of a thiazine-based BACE1 inhibitor 5 with robust A beta reduction in vivo at low concentrations, leading to a low projected human dose of 14 mg/day where 5 achieved sustained A beta reduction of 80% at trough level.
