Microwave-assisted regioselective reaction of furanone derivative supported by DFT stimulation and molecular docking to afford controlling insecticidal agents

The furanone 1 was allowed to react with different nitrogen nucleophiles such as hydrazine hydrate, hydroxyl amine, anisidine, anthranilic acid, glycine, ethylglycinate and isatin and some carbon nicleophiles under Michael reaction conditions assisted by microwave irradiation. They afforded new synthesized some important heterocyclic compounds 2-16. The structures of the synthesized new compounds were characterized by spectral data and elemental analysis. DFT calculation is serving to clarify not only the active electrophilic sites attacked by suitable nucleophiles in the organic reaction but also the bioactivity of the larvicidal compounds. The larvicidal activities of the synthesized compounds were tested against Plutella xylostella and Helicoverpa armigera larvae in vitro. The results revealed that the synthesized compounds 4, 13 and 14 showed good insecticidal activity against Plutella xylostella larvae with 100%, 87.2% and 91.4% activities, respectively, while 13 and 14 displayed 92% and %, 94.8 activities, respectively, against Helicoverpa armigera larvae. Therefore, they exhibited good larvicidal activity. The executed molecular docking simulations evinced the selective binding of the novel synthesized compounds toward acetylcholinesterase (AchE) of Drosophila Melanogaster, which signifies their role as a prominent larvicides. Compound 4, 13 and 14 showed clear docking affinity and to the assumed binding sites in terms of both calculated binding energies and the types of interactions, which provided a solid rationalization for the conducted experimental results.

Synthesis of 6,7-Dihydropyrrolo[2,1-c][1,3]thiazino[3,2-a]pyrazine-4(11bH)-(thi)ones from 1,2-Dithiolo-3-(thi)ones

An efficient synthesis of 6,7-dihydropyrrolo[2,1-c][1,3]thi-azino[3,2-a]pyrazine-4(11bH)-(thi)ones from readily available 1,2-di-thiolo-3-(thi)ones and 3,4-dihydropyrrolo[1,2-a]pyrazine is reported. The S2 atom in both monocyclic and fused 1,2-dithioles is selectively replaced by aminomethylene to afford fused, rigid six-membered 1,3-thiazines. The scope of this two-step one-pot reaction was investigated: 1,2-dithiolo-3-ones were more reactive than the corresponding 1,2-dithiole-3-thiones. Optimized reaction conditions and a mechanistic rationale for the ring transformation are presented.

Stereoselective synthesis of 4-aminobenzo[c][1,2] thiazine via modification of the Harmata benzothiazine synthesis

A stereoselective synthesis of 4-aminobenzothiazines was developed through a modified Harmata benzothiazine synthesis. The reaction has very good substrate scope and good functional group tolerance was observed. The products were obtained with high enantiomeric purity. Many interesting heterocyclic analogues were made using this methodology.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 10297-73-1. Category: thiazines.

Sulthiame add-on therapy for epilepsy

Background Epilepsy is a common neurological condition characterised by recurrent seizures. Most patients respond to conventional antiepileptic drugs, however, around 30% will continue to experience seizures despite 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 compare the efficacy and side-effect profile of sulthiame as add-on therapy compared with placebo or another antiepileptic drug. Search methods We searched the Cochrane Epilepsy Group’s Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, ClinicalTrials.gov and the WHO ICTRP Search Portal on 11 August 2015. No language restrictions were imposed. We contacted the manufacturers of sulthiame and researchers in the field to seek any ongoing or unpublished studies. Selection criteria Randomised controlled add-on trials of sulthiame 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. The following outcomes were assessed: 1) reduction in seizure frequency of 50% or greater 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 drug effects; and 6) quality of life scoring. Primary analyses were intention-to-treat. We present a narrative analysis. Main results We included one trial with 37 participants with a new diagnosis of West syndrome. Sulthiame was given as an add-on therapy to pyridoxine. No data were reported for outcomes 1), 3) or 6). Overall risk ratio with 95% confidence intervals (CI) for complete cessation of seizures during a nine-day follow-up period versus placebo was 0.71 (95% CI 0.53 to 0.96). Meaningful analysis of time to treatment withdrawal and adverse drug effects was not possible due to incomplete data. Authors’ conclusions Sulthiame may lead to a cessation of seizures when used as an add-on therapy to pyridoxine in patients with West syndrome. The included study was small and had a significant risk of bias which limits the impact of the evidence. No conclusions can be drawn about the occurrence of adverse drug 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 patients with epilepsy outside West syndrome. Large, multi-centre randomized controlled trials are necessary to inform clinical practice if sulthiame is to be used as an add-on therapy for epilepsy.
