An oxidative coupling product of luteolin with cysteine ester and its enhanced inhibitory activity for xanthine oxidase

Oxidative coupling reactions of several flavonoids with a cysteine ester (a radicalic and nucleophilic biochemical) were carried out and the abilities of the coupling products against xanthine oxidase (XO) were screened. One of the products, derived from luteolin, showed a notable inhibitory effect. A potent XO inhibitory compound was isolated from the complex mixture of the product of the coupling of luteolin and cysteine ethyl ester, and its structure was determined by NMR and MS analysis. The compound has a unique 1,4-thiazine ring unit on the luteolin B-ring and is inhibited XO 4.5 times more strongly than it did luteolin. (C) 2015 Elsevier Ltd. All rights reserved.

Crystal structure of meso-3,3 ‘-(1,4-ohenylene)bis(2-phenyl-2,3,5,6-tetrahydro-4H-1,3-thiazm-4-one)

The crystal structure of the title compound – meso-C26H24N2O2S2 with two stereocenters – has half the molecule in the asymmetric unit with the other half generated by a crystallographic center of inversion. The thiazine ring is in a conformation that is between half-chair and envelope [theta = 52.51 (17)degrees]. The phenyl ring on the 2-carbon atom of the thiazine ring is pseudo-axial. The central phenyl ring of the molecule is close to orthogonal to the phenyl rings on either side with an angle of 76.85 (11)degrees between those planes. In the crystal, pairwise, weak C-H center dot center dot center dot O hydrogen bonds between the central phenyl ring and the oxygen atoms of neighboring molecules result in continuous strips propagating along the a-axis direction. Hydrophobic interactions of the C-H center dot center dot center dot pi type are also observed.

Breslow Intermediates from a Thiazolin-2-ylidene and Fluorinated Aldehydes: XRD and Solution-Phase NMR Spectroscopic Characterization

The first generation and X-ray diffraction (XRD) analysis of a crystalline Breslow intermediate (BI) derived from a thiazolin-2-ylidene, that is, the aromatic heterocycle present in vitamin B-1, is reported. Key to success was the combined use of pentafluorobenzaldehyde and a thiazolin-2-ylidene carrying an enol-stabilizing dispersion energy donor as N-substituent. A so-called primary intermediate (PI) could be isolated in protonated form (pPI) as well and analyzed by XRD. Furthermore, the first stable BI derived from an aromatic thiazolin-2-ylidene and an aliphatic aldehyde (trifluoroacetaldehyde) was prepared and characterized by NMR spectroscopy in solution. When switching to a saturated thiazolidin-2-ylidene, reaction with pentafluorobenzaldehyde afforded a new BI in solution (NMR spectroscopy). Attempts to crystallize the latter BI resulted in the isolation of a novel thiazolidin-2-ylidene dimer that had undergone rearrangement to a hexahydro[1,4]-thiazino[3,2-b]-1,4-thiazine.

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 5326-23-8. COA of Formula: C6H4ClNO2.

Oxicams, a Class of Nonsteroidal Anti-inflammatory Drugs and Beyond

Oxicams are a class of nonsteroidal anti-inflammatory drugs (NSAIDs) structurally related to the enolic acid class of 4-hydroxy-1,2-benzothiazine carboxamides. They are used clinically to treat both acute and chronic inflammation by inhibiting the activity of the two cyclooxygenase (COX) isoforms, COX-1 and COX-2. Oxicams are structurally distinct from all other NSAIDs, exhibiting a novel binding pose in the COX active site. The 4-hydroxyl group on the thiazine ring partners with Ser-530 via hydrogen bonding while two coordinated water molecules mediate a polar interaction between the oxicam and COX. The rotation of Leu-531 in the complex opens a new pocket, which is not used for binding other NSAIDs to the enzyme. This structure provides the basis for understanding documented structure-activity relationships within the oxicam class. In addition, from the oxicam template, a series of potent microsomal prostaglandin E synthase-1 (mPGES-1) inhibitors represents a new direction for drug development. Here, we review the major route of oxicam synthesis and structure-activity for COX inhibition, as well as recent advances in oxicam-mediated mPGES-1 inhibition.

One-pot cis-selective route to sugar-fused thiazines via a masking-unmasking strategy in basic ionic liquid

A novel sequential Knoevenagel condensation, thia-Michael, and amino/mercaptoacetylative ring transformation reaction cascade for cis-selective synthesis of sugar-fused 1,3-thiazine is reported. The expeditious one-pot multicomponent annulation was performed using masked amino acid viz. 2-phenyl-1,3-oxazol-5-one or masked mercaptoacid viz. 2-methyl-2-phenyl-1,3-oxathiolan-5-one, D-xylose/D-glucose, and N-aryldithiocarbamic acid in ionic liquid [bmim] OH. The acetophenone obtained as a by-product and [bmim] OH itself could be easily recycled for further use without loss of efficiency. The envisaged method is operationally simple, high yielding, and excellent diastereoselective in favor of the cis-isomer of fused thiazines.

Synthesis of New Derivatives of Heterocyclic Systems Containing Triazolopyrimidine, thiazolo[3,2-a]pyrimidine and pyrimido[2,1-b] thiazine Moiety Showing Promising Antimicrobial Activity

Background and Objective: Continuing our research in the field of heterocyclic compounds and exploiting our experience in the synthesis of pyridothieno(furo)[3,2-d]pyrimidine derivatives decorated by suitable reactive groups (in turn able to give rise to the formation of new heterocyclic rings), we now carried out a research with the aim of building in different position of the pyrimidine some new hetero-rings: the 1,3,4-triazole, thiazole and thiazine. Moreover their possible antimicrobial activity against some gram-positive and gram-negative bacilli strains has been evaluated. Methods: Starting from the hydrazino derivative of pyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidines 2 (7) by reflux with triethyl orthoformate or formic acid, some substituted isomeric pyrido[3′,2′:4,5]thieno(furo)[2,3-e][1,2,4]triazolopyrimidines 3 and 4 (10) have been synthesized. By alkylation of compounds 8 with alkyl dichlorides, the cyclization to a thiazoline or to a thiazine ring on the [a] side of the pyrimidine ring occurs, with the formation of the new pentacyclic systems: pyrido[3′,2′:4,5]thieno[3,2-d][1,3]thiazolo[3,2-a]pyrimidin-7(8)-one 15 and pyrido[3 ”,2 ”:4′,5′]furo(thieno)[3′,2′:4,5]pyrimido[2,1-b][1,3]thiazin-7(8)-ones 16. Results: 11-Alkyl(aryl)-8,8-dimethyl-7,10-dihydro-8H-pyrano[4 ”,3 ”:4′,]pyrido[3′,2′:4,5]thieno[2,3-e][1,2,4] triazolo[4,3-c]pyrimidines 3 gave a Dimroth rearrangement in acidic media. It was observed that the cyclization of compounds 7 and 8 occurred linearly with the expected formation of pyrido[3′,2′:4,5]thieno(furo)[3,2-d][1,2,4]triazolo[4,3-a]pyrimidin-7(8)-ones 10 and pyrido[3′,2′:4,5]thieno[3,2-d][1,3]thiazolo[3,2-a]pyrimidin-7(8)-one 15 and pyrido[3 ”,2 ”:4′,5′]furo(thieno)[3′,2′:4,5]pyrimido[2,1-b][1,3]thiazin-7(8)-ones 16: that is triazole, thiazole and thiazine ring condensation occurs at the [b] side of the pyrimidine ring. During the alkylation of compounds 7, the unusual cleavage of the hydrazino group took place with the formation of 8(9)-methylpyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidin-7(8)-ones 12. Conclusion: The synthesis of some new ‘complex’ pentaheterocyclic systems containing triazolopyrimidine, thiazolo[3,2-a]pyrimidine and pyrimido[2,1-b]thiazine moiety based on the pyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidines is described. During the alkylation of 9(10)-hydrazinopyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidin-7(8)-ones 7 an unexpected cleavage of the hydrazino group has been observed with the formation of 8(9)-methylpyrido[3′,2′:4,5]thieno(furo)[3,2-d]pyrimidin-7(8)-ones 12. Biological tests on the newly synthesized compounds evidenced that some of them showed promising antimicrobial activity.
