Synthesis of Some New Azoloazines with Potent Anti-inflammatory and Analgesic Activity

Starting from pyrimidine-2-thiones, a set of new fused triazoles, thiazoles, and thiazines has been obtained. The mechanistic pathway and structures of all the novel products were ascertained on the foundation of spectral information and elemental analyses. The analgesic and anti-inflammatory activities of all the prepared compounds were predestined. The outcomes disclosed that all of the examined samples revealed potent activity. Moreover, the relation between the structure and the activity has been researched.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 7143-01-3, you can contact me at any time and look forward to more communication. Quality Control of Methanesulfonic anhydride.

Crystal structures of two 2,3-diary1-2,3-dihydro-4H1,3-benzothiazin-4-ones

The syntheses and crystal structures of 2,3-bis[3-(trifluoromethyl)phenyl]-2,3dihydro-4H-1,3-benzothiazin-4-one (di-m-CF3; C22H13F6NOS) (1) and 2,3-bis(4-methylphenyl)-2,3-dihydro-4H-1,3-benzothiazin-4-one (di-p-CH3; C22H9NOS) (2) are reported. Each structure is racemic: the asymmetric unit of 2 consists of two molecules. In both 1 and 2, the six-membered 1,3-thiazine ring is close to an envelope conformation with the chiral C atom forming the flap. In 1, the 2-aryl group is pseudo-equatorial, while in 2 it is pseudo-axial. In 1, the pendant aryl rings form a V shape with an inter-centroid distance of 3.938 (3) A and an acute dihedral angle of 48.3 (2) between them. Both CF3 groups are disordered over two orientations in 0.687 (19):0.313 (19) and 0.667 (16):0.33 (16) ratios. In each of the independent molecules of 2, the aryl rings are almost orthogonal to each other [dihedral angles = 85.50 (12) and 86.07 (11) I. In both structures, the chiral C atom and the 0 atoms participate in C-H center dot center dot center dot O-type hydrogen bonding between symmetry-related molecules of 1 or the independent enantiomers in 2, forming chains along the c-axis direction in 1 and the b-axis direction in 2. Additionally, in 1, pi-pi contacts of both face-to-face and edge-to-face type, as well as pi-H center dot center dot center dot O and pi-H center dot center dot center dot F interactions are observed. In 2, a racemic mixture of molecules forms layers in the ac plane linked by weak pi-pi and C-H center dot center dot center dot pi interactions.

Synthesis of quinoline/naphthalene-containing azaphenothiazines and their potent in vitro antioxidant properties

New tetracyclic and pentacyclic azaphenothiazines containing one or two quinoline rings instead of benzene rings were obtained in the original reactions of isomeric diquinodithiins, dichlorodiquinolinyl sulfides, and disulfide with aromatic amines. The type of ring fusion in the azaphenothiazine system was concluded from the H-1 NMR spectra. The obtained azaphenothiazines were evaluated in vitro for their antioxidant activity on rat hepatic microsomal membranes for protection of non-enzymatic lipid peroxidation promoted by the Fe2+/ascorbic acid redox system. Most compounds exhibited a very significant antioxidant activity with IC50 values between 1 and 23 mu M. The degree of antioxidant activity depends on the lipophilicity and molecular size as well as the (non)substitution of the thiazine nitrogen atom and type of ring system fusion. It is the first time to our knowledge that azaphenothiazines are shown to exhibit such potent antioxidant activity.

The complex of zinc with N-(5,6-dihydro-4H-1,3-thiazine-2-yl)benzamide

A complex of zinc with N-(5,6-dihydro-4H-1,3-thiazin-2-yl)benzamide (L) ligand, LZnCl2, was synthesized for subsequent medical trials. The molar extinction coefficients were determined for LHBr solutions in water and physiological saline, and for LZnCl2 ethanol solution. The ligand stability in various solvents was evaluated and the value of its protonation constant was found for the physiological saline solution, logK = 5.3 +/- 0.2. The impossibility of determination of the complex stability constant by the potentiometric titration method was demonstrated. The complex exhibited an insufficient stability in aqueous and physiological saline solutions, but was stable as the solution in alcohol. There was no sorption observed upon the treatment of ligand with hydroxyapatite nanoparticles, which could be a potential carrier for the therapeutic form of LZnCl2, providing additional degrees of freedom for the interaction of ligand with cell membranes and a prolonged action of zinc ions.

A new route for the synthesis of pyrimido[2,1-b][1,3]thiazine ring system

A simple and efficient pathway to conjugate monosaccharides to thienopyrimidines via click chemistry establishing a 1,2,3-triazole linker was reported. Potential pharmaceutical interest is envisaged for the expected target products. Starting from a 2-isothiocyanate-thiophene-3-carboxylate, an allylthiourea was obtained with allylamine, cyclized and S-propargylated to give a thienopyrimidine-alkyne core. Click reaction with tetraacetyl-1-azidoglucose was successful to give the target conjugate with one sugar unit. When propargylamine was used in the first step, the expected thiourea cyclized via the alkyne moiety leading to pyrimido[2,1-b][1,3]thiazine.

Epinephrine electrochemical sensor based on a carbon paste electrode modified with hydroquinone derivative and graphene oxide nano-sheets: Simultaneous determination of epinephrine, acetaminophen and dopamine

In this paper, an electrochemical sensor was constructed for determination of epinephrine based on carbon paste electrode (CPE) modified with graphene oxide (GO) and 2-(5-Ethyl-2,4-dihydroxyphenyl)-5,7-dimethy1-4H-pyrido[2,3-d][1,3]thiazine-4-one (EDDPT) as modifiers. The modified electrode was applied as an electrochentical sensor for oxidation of epinephrine (EP). Under the optimum conditions, the over potential of EP oxidation decreased about 279 mV at the modified CPE more than a non-modified CPE. Electrochemical behavior of EP was investigated on the fabricated electrode by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) methods, and some kinetic parameters of EP Were obtained, too. The linear range and the detection limit for EP were found to be 1.5-600.0 WM and 0.65 uM (based on 3 sum), respectively using the EDDPT/GO/CPE sensor and the differential pulse voltammetry (DPV) method. Also, the designed electrochemical sensor was applied to determine EP in the drug sample and simultaneous determination of epinephrine (EP), acetaminophen (AC) and dopamine (DA) in human serum solutions.

Synthesis of 5,6-dihydro-4H-1,3-thiazine containing peptide mimics from N-(3-hydroxypropyl)thioamides and epimerization studies

The first synthesis of 1,3-thiazine fused peptide mimics is described from N-(3-hydroxypropyl)thioamides under MsCl/NEt3 conditions. The method is amenable to oligopeptidomimics with polar and apolar side chains. Substantial epimerization occurs at chiral C(2) exo methines in non-Pro fused mimics even under neutral conditions. H-1 NMR and crystal structure analyses indicate that the Thi analogues primarily associate with each other through intermolecular hydrogen bonds, involving the nitrogen of 1,3-thiazine and the N-H of the fused residue, which may be the basis for enamination-racemization process in these peptide mimics.
