Aulosirazole, the major cytotoxin in the blue-green alga (cyanobacterium) Aulosira fertilissima Ghose (UH strain DO-8-1), shows solid tumor selective activity in the Corbett assay. Its structure has been determined to be 5-hydroxy-3-methoxynaphtho[2,3-d]-1,2-thiazole-4,9-dione by a combination of spectroscopic, notably NMR, and X-ray crystallographic methods. The carbon skeleton and the juglone nature of 1 was determined by two-dimensional H-1-C-13 NMR correlation spectral analysis and one-dimensional C-13-C-13 decoupling experiments, the latter on the C-13-enriched cytotoxin. The presence of an isothiazole ring and the position of attachment for the juglone system was rigorously established by an X-ray crystallographic study.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield.

The antifungal activity of 4-amino-3-methyl-1 -phenylpyrazolo-(3,4-c)isothiazole was studied on Trichophyton rubrum. The compound, at concentrations between 20 and 100 mu g ml(-1), induces a remarkable reduction in the growth and causes deep morphogenetic anomalies. The ultrastructural modifications have demonstrated that the compound targets the cell membrane of the fungus, breaking down not only the endomembrane system, but also the ‘outer’ membrane, with consequent extrusion of materials in the medium. The results suggests a mechanism of action similar to other azoles clinically utilized.

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 95-01-2. Synthetic Route of 95-01-2.

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.

Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 92-91-1, Name is 1-([1,1′-Biphenyl]-4-yl)ethanone, SMILES is CC(C1=CC=C(C2=CC=CC=C2)C=C1)=O, in an article , author is Liu, Genyan, once mentioned of 92-91-1, Reference of 92-91-1.

gamma-Aminobutyric acid (GABA) receptors are important targets of parasiticides/insecticides. Several 4-substituted analogs of the partial GABA(A) receptor agonist 5-(4-piperidyl)-3-isothiazolol (Thio-4-PIOL) were synthesized and examined for their antagonism of insect GABA receptors expressed in Drosophila S2 cells or Xenopus oocytes. Thio-4-PIOL showed weak antagonism of three insect GABA receptors. The antagonistic activity of Thio-4-PIOL was enhanced by introducing bicyclic aromatic substituents into the 4-position of the isothiazole ring. The 2-naphthyl and the 3-biphenylyl analogs displayed antagonist potencies with half maximal inhibitory concentrations in the low micromolar range. The 2-naphthyl analog induced a parallel rightward shift of the GABA concentration-response curve, suggesting competitive antagonism by these analogs. Both compounds exhibited weak insecticidal activities against houseflies. Thus, the orthosteric site of insect GABA receptors might be a potential target site of insecticides. (C) 2014 Elsevier Ltd.

Quality Control of Isobutyrophenone, Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. 611-70-1, Name is Isobutyrophenone, SMILES is CC(C)C(=O)C1=CC=CC=C1, belongs to isothiazole compound. In a article, author is MARTENS, T, introduce new discover of the category.

The title compounds are obtained in good yields from 1,2-dithiole-3-thiones. Using cyclic voltammetry in dimethylformamide, two kinds of behaviour are evidenced and discussed in terms of the aromaticity of the 5-substituent (Ar). With Ar = pyrazinyl or pyridazinyl, isothiazole-3-thiones undergo an electrochemical chemical electrochemical mechanism and the rate constant of the chemical step has been deduced from voltammetric measurements. When the aromaticity increases (Ar = pyridyl or phenyl) an apparent one-step irreversible two-electron addition occurs. Whatever the nature of Ar the resulting two-electron reduction product has been isolated after controlled-potential electrolysis (CPE). In addition, in acetonitrile, CPE affords a thiophene derivative as a secondary product.
