The distribution of complexes (ZnLCl2)-Zn-69m-Cl-1, [Zn-69m(L-2)(2)]Cl-2, and [Zn-69m(L-2)(2)]Sal(2) (L-1 is N-(5,6-dihydro-4H-1,3-thiazin-2-yl)benzamide, L-2 is 2-aminopyrimidine, Sal is a salicylate ion) in vivo in mice

The distribution of complexes of thiazine and pyrimidine derivatives possessing antileukemic activity and labeled with radionuclide Zn-69m in the organs of mice and its rate of excretion were studied. A solution of ZnCl2 was used for comparison. An increase in the time of excretion of the drug from the body and a decrease of its penetration into the brain in the presence of a salicylate ion were observed.

Copper(I)-Catalyzed Oxidative Coupling between 2-Aminobenzothiazole and Terminal Alkyne: Formation of Benzothiazine

An unprecedented formation of benzothiazine during copper(I)-catalyzed oxidative coupling of 2-aminobenzothiazole and terminal alkyne in air has been observed. This unique transformation possibly occurs through the ring opening of 2-aminobenzothiazole and subsequent oxidative coupling with alkyne followed by intramolecular cyclization. A variety of substituted benzo[b][1,4]thiazine-4-carbonitriles are obtained by this protocol.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 154445-78-0, you can contact me at any time and look forward to more communication. COA of Formula: C13H17ClO3S.

An operational study comparing microscopes and staining variations for tuberculosis LED FM

SETTING: Tuberculosis control projects, Damien Foundation Bangladesh. OBJECTIVES: To compare transmitted fluorescence (Olympus CX21 (TM)/FRAEN FluoLED (TM)) with epi-fluorescence (Zeiss Primostar iLED (TM)) light-emitting diode microscopes (LED-FM) and various auramine staining and destaining/counterstaining techniques for the detection of acid-fast bacilli. DESIGN: Multicentre blinded reading of routine smears on both types of microscopes using different staining techniques in multiple phases. LED-FM rechecking of discordant series with and without restaining to calculate operating characteristics. RESULTS: Among 64 874 smears, both instruments detected 9.6% positives. Compared to the standard technique, the stronger auramine-O formulation did not perform better. Thiazine red counterstaining tended to yield more false-positive as well as false-negative errors. Combined destaining/counterstaining (sensitivity 93%, positive predictive value [PPV] 98%) proved significantly less effective. Both destaining with 1% hydrochloric acid (HCl) and 10% alcohol and the standard 0.5% HCl and 70-95% alcohol were equally accurate (sensitivity 95-96%, PPV 99%). The sturdiness of the microscopes in field conditions was sub-optimal: only 5/16 instruments did not break down. CONCLUSIONS: Both microscopes performed equally well. The standard staining technique is as good as the more complicated and expensive variations. A destaining solution containing only 10% alcohol works perfectly well. The inferior quality of LED-FM microscope components is an obstacle to FM expansion.

Synthesis of fluorine-containing 1,3-thiazine derivatives from primary polyfluoroalkanethioamides

New fluorine-containing 1,3-thiazine derivatives were obtained by the reactions of primary polyfluoroalkanethioamides with methyl vinyl ketone and ethyl acrylate in the presence of boron trifluoride etherate. The outcome of the reactions depends on the type of alpha,beta-unsaturated carbonyl compound and the polyfluoroalkyl chain length. Hydrolysis of the obtained 1,3-thiazines leads to the formation of thioester derivatives. (C) 2014 Elsevier B.V. All rights reserved.

Crystal structure of the 1 : 1 adduct of 2,3-diphenyl-3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one with triphenyltin chloride

The title adduct, chlorido(2,3-diphenyl-3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one-kappa O) triphenyltin, [Sn(C6H5)(3)Cl(C16H15NOS)], resulted from reaction of 2,3-diphenyl- 3,4,5,6-tetrahydro-2H-1,3-thiazin-4-one with triphenyltin chloride. The thiazine ring has an envelope conformation with the S atom forming the flap. The molecule has five phenyl rings, two of them attached to the thiazine ring at positions 2 and 3, and three in coordination with the Sn-IV atom. The three rings of the triphenyltin group are involved in intramolecular interactions of different types, C-H center dot center dot center dot O, edge-to-face (or T-type) pi-pi interactions with the 3-phenyl ring of the thiazine, T-type interactions with both phenyl rings of the thiazine etc. On the other hand, all the phenyl rings participate in intermolecular pi-pi interactions. There is one instance of a ‘parallel-displaced’-type interaction extending continuously along the a-axis direction and seven instances of T-type interactions stabilizing the crystal lattice.

Synthesis, Structural Elucidation, Cyclic Voltammetry, and Theoretical Modelling of 2-Ferrocenyl-4H-benzo[e][1,3]thiazines and 2-Aryl-4H-ferroceno[e][1,3]thiazines

2-Ferrocenyl-4H-benzo[e][1,3]thiazine and its 6,7-dimethoxy derivative were prepared by a Bischler-Napieralski-type annulation of the Mannich adducts of ferrocenecarboxamide, formaldehyde, and the corresponding thiophenol. A more efficient synthetic pathway, comprising a directed lithiation/iodination sequence followed by standard functional-group transformations and a final copper-catalyzed cyclization, was elaborated to convert [(dimethylamino)methyl]ferrocene into racemic mixtures of the first representatives of planar-chiral 4H-ferroceno[e][1,3]thiazines. A similar strategy with 2-iodobenzyl bromide as the precursor enabled a highly improved synthesis of 2-ferrocenyl-4H-benzo[e][1,3]thiazine. The relative tendency of the new ferrocene-based thiazines, composed of potential redox sites assembled in different molecular architectures, to behave as donors in single-electron transfer (SET) reactions was studied by cyclic voltammetry (CV) and DFT calculations. The results disclosed that 2-ferrocenyl-4H-ferroceno[e][1,3]thiazine can undergo two consecutive redox steps and is the most efficient reductant among the prepared models; it has the lowest first half-cell potential, the highest-energy highest occupied molecular orbital (HOMO) concentrated on the fused metallocene unit and the lowest first ionization energy.

Crystal Structure of Ethyl 2,4-Dimethyl-1-phenyl-6-thioxo-1,6-dihydropyrimidine-5-carboxylate: The Product from the Reaction of Ethyl 3-Aminocrotonate, Phenylisothiocyanate and Acetic Anhydride

The crystal structure of ethyl 2,4-dimethyl-1-phenyl-6-thioxo-1,6-dihydropyrimidine-5-carboxylate (7) has been determined (monoclinic, P2(1)/n, a 12.5543(9); b 7.6345(4); c 16.1568(14) , beta 107.210(9)A degrees) revealing a thioamide functional group instead of the thiazine ethyl (Z)-2,4-dimethyl-6-(phenylimino)-6H-1,3-thiazine-5-carboxylate (5) proposed previously. This has required the revision of the published structure for this multicomponent reaction which now has identified (7), not (5), as the product, supported by NMR and IR analysis. The crystal structure of the major product from the reaction of ethyl 3-aminocrotonate, phenylisothiocyanate and acetic anhydride is ethyl 2,4-dimethyl-1-phenyl-6-thioxo-1,6-dihydropyrimidine-5-carboxylate (shown), not the previously identified ethyl (Z)-2,4-dimethyl-6-(phenylimino)-6H-1,3-thiazine-5-carboxylate.
