Objective: This research is to investigate the antihyperglycaemic activity and the underlying mechanisms of action of the ethylacetate extract of Chlorophytum alismifolium (EACA) tubers in a type 2 diabetes model. Methods: The tubers were processed and sequentially extracted in hexane followed by ethylacetate, using a Soxhlet apparatus, and subjected to gas chromatography-mass spectrometry (GC-MS). The acute toxicity of EACA was investigated in albino Wistar rats. An antihyperglycaemic study was carried out using high-fat diet (pelletized diet and margarine in the ratio of 10:1 and 20% fructose solution) and streptozotocin-induced hyperglycaemic Wistar rats. The effects of the extract (150, 300 and 600 mg/kg) on blood glucose level, insulin, peroxisome proliferator-activated receptor gamma (PPAR-gamma) and dipeptidyl peptidase-4 (DPP-4) were evaluated using enzyme-linked immunosorbent assay. Results: The oral median lethal dose in Wistar rats was estimated to be > 5000 mg/kg. Treatment with EACA at all doses significantly reduced the fasting blood glucose levels, compared to the hyperglycaemic control, and over time. Administration of EACA increased the serum insulin and PPAR-gamma levels while decreasing DPP-4 levels. GC-MS analysis revealed the presence of 13 compounds, with isothiazole and isoxazolidine covering total area of 24.6% and 22.69%, respectively. Conclusion: The findings from this study showed that EACA has important compounds with beneficial effect in type 2 diabetes and acts by increasing insulin secretion and PPAR-gamma level and decreasing DPP-4 activity.

This study is concerned with the implementation of structure-based techniques for the design of new heterocyclic compounds based on pseudosaccharine scaffold with protein kinase inhibition activity. This nucleus was exploited based on the well-known quinazoline core and its interactions with several protein kinases. Two series of compounds employing this new scaffold were synthesized and evaluated at enzymatic and cellular levels. Compound 9b displayed broad spectrum antiproliferative activity on NCI 60-cell lines panel with mean GI(50) of 5.4 mu M. Investigation of the molecular mechanism showed probable inhibitory activity against Src kinase. (C) 2012 Elsevier Masson SAS. All rights reserved.

In an article, author is Swiatek, Piotr, once mentioned the application of 91-40-7, Name is 2-(Phenylamino)benzoic acid, molecular formula is C13H11NO2, molecular weight is 213.2319, MDL number is MFCD00002421, category is isothiazole. Now introduce a scientific discovery about this category, Quality Control of 2-(Phenylamino)benzoic acid.

One of the main challenges for nowadays medicine is drugs selectivity. In COX-1 and COX-2, the active sites are composed of the same group of amino acids with the exception of the only one residue in position 523, in COX-1 is an isoleucine, while in COX-2 is a valine. Here, we presented a series of isothiazolopyridine/ benzisothiazole derivatives substituted differently into an isothiazole ring, which were synthesized and investigated for their potencies to inhibit COX-1 and COX-2 enzymes by colorimetric inhibitor screening assay. All the tested compounds inhibited the activity of COX-1, the effect on COX2 activity was differential. The mode of binding was characterized by a molecular docking study. Comparing biological activity of the investigated compounds, it was observed that compounds sharing the most similar position to flurbiprofen and meloxicam, representing the two main enzyme subdomains, achieved higher biological activity than others. It is directly related to the fit to the enzyme’s active site, which prevents too early dissociation of the compounds. (C) 2016 Elsevier Ltd. All rights reserved.

Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.3466-32-8, Name is 1-Bromo-4-(methylsulfonyl)benzene, SMILES is O=S(C1=CC=C(Br)C=C1)(C)=O, belongs to isothiazole compound. In a document, author is Ioannidou, Heraklidia A., introduce the new discover, Product Details of 3466-32-8.

The conversion of isothiazoles into pyrazoles on treatment with hydrazine is investigated. The influence of various C-3, C-4 and C-5 isothiazole substituents and some limitations of this ring transformation are examined. When the isothiazole C-3 substituent is a good nucleofuge, 3-aminopyrazoles are obtained. However, when the 3-substituent is not a leaving group it is retained in the pyrazole product. Treatment of 4-bromo-3-chloro-5-phenylisothiazoie 56 or 3-chloro-4,5-diphenylisothiazole 57 with anhydrous hydrazine at ca. 200 degrees C for a few minutes gives the corresponding 3-hydrazinoisothiazoles 61 and 64 respectively in high yields; the stability of these new hydrazines is investigated. 5,5′-Diphenyl-3,3′-biisothiazole-4,4′-dicarbonitrile 78 reacts with hydrazine to give 5,5′-diphenyl-3,3′-bi(1H-pyi-azole)-4,4′-dicarbonitrile 79. Methylhydrazine reacts with 3-chloro-5-phenytisothiazole-4-carbonitrile 1 to give 3-(1-methylhydrazino)-5-phenylisothiazole-4-carbontrile 83 and 3-amino-lmethyl-5-phenylpyrazole-4-carbonitrile 84. All products are fully characterised and rational mechanisms for the isothiazole into pyrazole transformation are proposed. (C) 2009 Elsevier Ltd. All rights reserved.

The palladium-catalyzed reaction of 5-bromo-3-diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide(3) with a variety of vinyl-, aryl-, heteroaryl- and alkynylstannanes 4 provides a general and efficient method for the synthesis of 5-substituted isothiazole 1,1-dioxides 5. Different reaction conditions (catalyst, solvent, temperature) were tested for the coupling. The best results were obtained using toluene at reflux and benzylchlorobis(triphenylphosphine)palladium as catalyst. When organostannanes appeared to be less reactive, prolonged heating resulted in the formation of variable amounts of the reduction product 3-diethylamino-4-(4 methoxyphenyl)-isothiazole 1,1-dioxide(1).

The cycloaddition of tri-O-benzyl-2,5-anhydro-D-allononitrile-N-sulfide with dimethyl acetylenedicarboxylate or with dimethyl fumarate followed by DDQ oxidation was found to give the benzoyl protected dimethyl 3-beta-D-ribofuranosyl-isothiazoledicarboxylate 10. This compound was converted to C-nucleosides 7a, 8 and 9, analogues of pyrazofurin, oxoformycin B and formycin respectively. Despite their structural similarities they did show neither antiviral nor antitumor activity.

Synthesis of epoxybenzo[d]isothiazole 1,1-dioxides via a reductive-Heck, metathesis-sequestration protocol

An atom-economical purification protocol, using solution phase processing via ring-opening metathesis polymerization (ROMP) has been developed for the synthesis of tricyclic sultams. This chromatography-free method allows for convenient isolation of reductive-Heck products and reclamation of excess starting material via sequestration involving metathesis catalysts and a catalyst-armed Si-surface.
