SYNTHESIS AND BIOLOGICAL EVALUATION OF SOME NEW OXAZINES AND THIAZINES

In an approach to hostile the growing microbial drug resistance and to advance new antimicrobial moieties having more potent effect, here we have synthesized some novel substituted heterocyclic chalcone derivatives containing oxazine and thiazine moieties. Conversion of 2, 4-dihydroxyphenyl-3-phenylpropenones into 4-(2-hydrazinyl-6-phenyl-6H-1, 3-oxazin-4-yl) benzene-1,3-diols 3(a-i) was achieved by stirring 2(a-i) with semicarbazide in ethanolic sodium hydroxide. Similarly, conversion of 2(a-i) into 4-(2-hydrazinyl-6-phenyl-6H-1, 3-thiazin-4-yl) benzene-1, 3-diols 4(a-i) was achieved by stirring 2(a-i) with thiosemicarbazide in ethanolic sodium hydroxide. All the compounds were screened for in vitro antimicrobial, anti-inflammatory, and cytotoxic activity. The newly synthesized compounds exhibited significant inhibition values compared to standard drugs.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 92-39-7 help many people in the next few years. Application In Synthesis of 2-Chloro-10H-phenothiazine.

Synthesis and biological evaluation as well as in silico studies of arylpiperazine-1,2-benzothiazine derivatives as novel anti-inflammatory agents

Novel arylpiperazine-1,2-benzothiazine derivatives have been designed and synthesized as potential antiinflammatory agents. Their structure and properties have been studied using spectroscopic techniques (H-1 NMR, C-13 NMR, FT-IR), MS, elemental analyses, and single-crystal X-ray diffraction (SCXRD, for compound 7b). This study aimed to evaluate the inhibitory activity of new derivatives against both cyclooxygenase isoforms COX-1 and COX-2 due to the similarity of new compounds to oxicams drugs from the NSAIDs group. All new compounds were divided into two series – A and B – with a different linker between thiazine and piperazines nitrogens. Series A included the three-carbon aliphatic linker and series B – two-carbon with a carbonyl group. According to in vitro and molecular docking studies all new compounds exhibited cyclooxygenase inhibitory activity. The series of A compounds included COX-1 inhibitors only. In contrast, the B series showed inhibition of both COX-1 and COX-2, which suggested the importance of the acetoxy linker for COX-2 inhibition. Moreover, the most selective compound 7b, towards COX-2, was non-toxic for the normal human cell line (in concentration of 10 mu M) comparable to reference drug meloxicam. Additionally, investigation of influence on model membranes confirmed the ability of the compound 7b to penetrate lipid bilayers which seemed to be important to the influence with membrane protein-cyclooxygenase.

A Straightforward Approach for the Synthesis of Novel Derivatives of Benzo[b]pyrazolo[5,1:2,3]pyrimido[4,5-e][1,4]thiazine

Several derivatives of the novel benzo[b]pyrazolo[5,1:2,3]pyrimido[4,5-e][1,4]thiazine ring system have been synthesized through the one-pot cyclocondensation of 6-bromo-7-chloro-2-(ethylthio)-5-methylpyrazolo[1,5-a]pyrimidine-3-carbonitrile (4) with o-aminothiophenol in the presence of Et3N in CH3CN.

One-Pot Multicomponent Synthesis and Anticancer Activity of 1,3-Cyclopentathiazine and Pyrimidothiazine Derivatives

Novel 1,3-cyclopentathiazine and pyrimidothiazine derivatives were synthesized starting from 7-benzyl-4-phenylcyclopenta[d][1,3]thiazin-2-amine (CTA) prepared by a one-pot multicomponent reaction of cyclopentanone, benzaldehyde, and thiourea. Cyclocondensation of CTA with benzylidenemalononitrile gave a pyrimidothiazine. Oxidation of cyclopentathiazine with hydrogen peroxide afforded the corresponding epoxide, while its alkylation with ethyl iodide yielded anN-ethyl derivative. Cyclopentylidenemalononitrile was reacted with formaline and carbon disulfide to obtain pyridine-4-carbonitrile and thiapyrane, respectively, and the reactions of cyclopentylidenemalononitrile with aryl isocyanate and aryl isothiocyanate gave condensed diimino-substituted cyclopentanaphthyridine-1,6-dione and dithiaacenaphthylene-3,8-diylidedibenzamide, respectively. Heating cyclopentanone with benzoyl isothiocyanate and benzoyl chloride produced a sulfide derivative and an enolic dione, respectively. The structures of the newly synthesized compounds were confirmed by spectral analysis, and some products were screened for anticancer activity.

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.

General synthetic approach towards annelated 3a,6-epoxyisoindoles by tandem acylation/IMDAF reaction of furylazaheterocycles. Scope and limitations

An efficient and versatile one-pot synthesis of 3,6a-epoxyisoindoles annelated with oxazine, oxazole, thiazine, thiazole, pyrimidine fragments and with their benzoannelated analogues is presented. The method is based on tandem N-acylation/intramolecular cycloaddition (the intramolecular Diels-Alder reaction of furan, IMDAF) reaction between alpha,beta-unsaturated acid anhydrides and alpha-furyl substituted azaheterocycles. The latter can be easily prepared by condensation of diverse furfurals and 1,2- or 1,3-N,X-binucleophiles (aminoalcohols, aminothiols, diamines). The observed IMDAF reaction is stereo-selective: exo-adducts are formed exclusively with large prevalence of one of the diastereoisomers. In most cases, the condensation/N-acylation/IMDAF reaction sequence may be carried out via a one-pot domino protocol. The scope and limitations of the proposed approach are thoroughly investigated. The obtained Diels-Alder adducts are attractive and useful substrates for further transformations. Fused isoindoles can be prepared from them in one-step by aromatization of the 7-oxabicyclo[2.2.1]heptene ring. Other transformations, including halogenation, ring cleavage, and Wagner-Meerwein skeletal rearrangement, are also demonstrated. The spatial structures of the obtained compounds have been established by X-ray diffraction analyses. (C) 2014 Elsevier Ltd. All rights reserved.
