A series of 4-isothiazolecarbonitriles was synthesized and screened for in vitro antiviral activity. The effect of various substituents on the phenyl ring, as well as the substitution of the phenyl for other aromatic and heteroaromatic rings, was examined to establish the requirements for optimum activity. The most active member of the series, 3-methylthio-5-phenyl-4-isothiazolecarbonitrile, exhibited a high level of activity against enteroviruses polio 1 and ECHO 9. Preliminary studies on its mechanism of action indicated that this compound had an effect on an early event in the replication of poliovirus type 1. (C) 1998 Published by Elsevier Science Ltd.

New Advances in Chemical Research in 2021, Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media. 3034-86-4, Name is Methyl 4-ethynylbenzoate, molecular formula is C10H8O2, belongs to isothiazole compound. In a document, author is Abdel-Magid, Ahmed F., introduce the new discover, Application In Synthesis of Methyl 4-ethynylbenzoate.

The invention in this patent application relates to isothiazole and thiophene derivatives represented generally by formula (I), which are GPR120 agonists and may potentially be useful for the treatment of Type 2 diabetes mellitus, obesity, obesity-related disorders, impaired oral glucose tolerance, and insulin resistance. Statistics have shown that current drug therapies for Type 2 diabetes are lacking durable efficacy. More than half of patients on current oral medications fail to reach the targeted blood glucose control after 5 years of treatment. Thus, there is an urgent need for new drug therapies to treat Type 2 diabetes. Glucagon-like peptide-1 receptor (GLP-1) is a member of the glucagon receptor family of G protein-coupled receptors. It is a key regulator of glucose homeostasis, which is secreted by the L-cells in the colon following meals. It is an incretin hormone that potentiates insulin secretion, reduces glucagon secretion, preserves beta-cell function, and improves satiety. GLP-1 has been a therapeutic target for several of the recently approved Type 2 diabetes drugs including Januvia (Merck) and Galvus (Novartis), which act by prolonging the half-life of GLP-1, and Byetta (Amylin), which acts by activating the GLP-1 receptor. The complex pathology of free fatty acids (FFAs) plays a key role in the progression of diabetes. While the acute exposure of FFAs in the pancreas and the colon stimulates glucose-dependent insulin secretion and GLP-1 release, chronic exposure of FFAs impairs insulin secretion and becomes toxic to beta-cells. The accumulation of FFAs in insulin responsive tissues such as muscles and liver causes tissue insulin resistance. Hyperinsulinemia in the liver has been linked to increased accumulation of fatty acids and hepatic glucose output, which cause impaired insulin resistance and create a vicious cycle of disease progression. Currently available Type 2 diabetes drugs can only treat some of the damaging effects of FFAs on the progression of diabetes. Therefore, researchers are aiming to develop effective new therapies that can address all or most of these effects to efficiently potentiate the release of GLP-1, significantly improve blood glucose control, maintain beta-cells function, and may additionally be capable of treating obesity. G-protein coupled receptor 120 (GPR120) is a member of the rhodopsin family of G protein-coupled receptors (GPCRs), which also includes GPR40, GPR41, and GPR43. GPR120 is expressed predominantly in the intestine and adipose tissue and functions as a receptor for long chain FFAs. It is activated by unsaturated long chain FFAs, which stimulate the secretion of GLP-1. It is believed that GPR120 signaling activates Ca2+ flux as well as protein kinase C (PKC), which may explain how FFAs contribute to the release of GLP-1 in the L-cells. While GPR120 is not yet very well studied, available data suggest that GPR120 agonists would potentiate insulin secretion and reduce glucagon indirectly via GLP-1 release. The beneficial effects of elevating GLP-1 levels are already well documented in clinical studies. Thus, GPR120 presents a potentially viable therapeutic target to develop novel treatments for Type 2 diabetes, obesity, and insulin resistance. GPR120 agonists such as the compounds described in this patent application may be effective in improving glucose homeostasis and can potentially treat obesity. They might additionally act as complementary treatments to existing diabetes therapies that affect liver insulin sensitivity and those that preserve beta-cells function.

New research progress on 3034-86-4 in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 3034-86-4, Name is Methyl 4-ethynylbenzoate, formurla is C10H8O2. In a document, author is Hegelund, F., introducing its new discovery. Name: Methyl 4-ethynylbenzoate.

The gas phase IR spectrum of isothiazole, C3H3NS, between 550 and 1700 cm(-1) was recorded with a resolution of ca. 0.003 cm (-1). The rotational structure of seven fundamental bands in the region 750-1500 cm-1 has been assigned and analysed by the Watson Hamiltonian model. A number of local resonances in the bands have been identified and explained qualitatively in terms of Coriolis interactions. For each band upper state spectroscopic constants, including band center, rotational constants, and quartic centrifugal distortion constants are given. From observed crossings due to resonances we locate the weak bands v(9)(A’) and v(13)(A’) at 1041.9(2) and 642.0(3) cm(-1) respectively. The anharmonic frequencies have been determined using a cc-pVTZ basis set, at the MP2 and B3LYP levels; the two theoretical methods give very similar results for rotational constants, anharmonic band center frequencies and distortion constants, and many of these are in good agreement with experiment.

Investigation of the reaction between benzo[d]isothiazol-3-one, 2-aminobenzo[d]isothiazol-3-one, its isoster 2-aminoisoindolin-1-one, and activated acetylenes, in the presence of triphenylphosphine, led us to synthesize novel heterocyclic compounds that could be attractive for the building of biologically active molecules. A one-pot PPh3-promoted tandem reaction, with acetylene dicarboxylates and dibenzoylacetylene, afforded new tricyclic pyrazolo-fused benzisothiazoles. The PPh3-promoted reaction between benzisothiazolones and methyl propiolate afforded 1,4-benzothiazepine-5-one derivatives, via an isothiazole ring expansion. These studies are providing additional insights in benzisothiazolone chemistry and describe simple and original synthetic accesses to novel derivatives.

New Advances in Chemical Research, April 2021. Synthetic Route of 3034-86-4, In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. The reactant in an enzyme-catalyzed reaction is called a substrate. 3034-86-4, Name is Methyl 4-ethynylbenzoate, SMILES is O=C(OC)C1=CC=C(C#C)C=C1, belongs to isothiazole compound. In a article, author is SWAYZE, EE, introduce new discover of the category.

A series of imidazo[4,5-d]isothiazoles have been prepared from isothiazole precursors via a strategy employing ring annulation of the appropriate isothiazole diamine. In this manner, several 4,5-diaminoisothiazoles were converted into the corresponding 5-(alkylthio)imidazo[4,5-d]isothiazoles via a two-step, one-pot procedure in good yield. This methodology proved quite general and allows for the introduction of various substituents onto the 3-, 5-, and 6-positions of this ring system. Reaction with Raney nickel destroyed the ring system, presumably through removal of the sulfur at the 1-position, and the 5-mercapto substituent could not be removed selectively. Ring annulation with diethoxymethyl acetate provided the 5-unsubstituted imidazo[4,5-d]isothiazoles but was less general, and only the 3-methyl derivatives could be prepared. Imidazo[4,5-d]isothiazoles bearing no substituents on nitrogen readily underwent alkylation to afford mixtures of the N-4- and N-6-substituted compounds. The chemical and physical properties of these novel heterocycles were studied in detail, and the structure of 3-methyl-5-methanesulfonyl-6-(phenylmethyl)imidazo[4,5-d] isothiazole was verified by single crystal X-ray diffraction studies.
